Battery Powered Garden Sprayer Buyer’s Guide

The pump pressure sprayers that we have been using for years in the fields work well, so the new battery powered garden sprayers have to be fully featured and highly capable to usurp them. The main concern when doing yard work on a battery is that you will run out of power in the middle of a job. Lucky, the battery technology and the sprayer technology has improved dramatically over the years. When shopping for a garden sprayer, be sure to keep a few key considerations in mind.

Tank Capacity

Tank capacity is top of mind when shopping for sprayers because you do not want to have to constantly refill your tank during a job. Most homeowners find that a two-gallon or a four-gallon sprayer are more than sufficient for jobs. Ultimately, the type of job you are doing, be it weed prevention, weed remediation, fertilizing, or pest control will determine the amount of spray that you need to dispense.

Battery Life

No one wants to find out that they can’t finish the job because their battery is dead, so when shopping for a garden sprayer be sure to find one that has suitable power. All lithium-ion batteries are not the same, so looking for a high capacity battery that can work for four, six, or even eight hours is ideal. Some models of sprayers even offer lead acid batteries to deliver more charge and power to the sprayer.

Sprayer Wand

It makes your job a lot easier when you can precisely deliver spray, so look for something that offers a long wand and long tube that is highly flexible. Also look for wands that have good cut-offs so that you can avoid leaking dangerous pesticides or harmful fertilizers where they don’t belong. Many sprayers also come with an assortment of nozzles to allow for cone, fan tip, or fog applications. Homeowners that might be reluctant to spray their yard or garden appreciate tips that help them precisely administer spray.

Backpack Comfort

It can be a long day working outside with a garden sprayer, so look for one that you can comfortably transport around your backyard or job site. Backpack sprayers are equipped with helpful straps and handles, and the nicest options include extra padding to protect your back and shoulders.

Before buying a battery powered sprayers take some time to consider how often you will spray and how long those spraying sessions should last. That way you can make sure that the battery life of your sprayers doesn’t leave you with jobs half completed. Also be sure to think about how big of jobs you plan to tackle and if a two gallon or four gallon sprayer is more appropriate.

Below are five of the best battery powered garden sprayers for you to consider. Any of the five sprayers can do a good job with most spraying jobs encountered in your backyard. Some have more features than others, but all are highly recommended and capable at getting the job done.

1. How far do backpack sprayers spray?

Maximum up to 30 - 35 feet

This varies with backpack sprayers, but most can handle between 10 and 30 feet, with a minimum is 10 feet, 20 feet for average, and 30 - 35 feet for maximum. This has an impact on the cost of each sprayer. The stronger motor, the further spray. Users can consider some factors like garden size, usability, whether using for heavy-duty or just for home use,...

2. How much pressure should the pump sprayer have?

90 - 150 PSI

PSI is the unit of measurement for pressure. In the United States, the pound per square inch is the most common unit of pressure for domestic, commercial, and industrial garden equipment. For the backpack sprayers, the majority is 90-150 psi on average. Some may be able to hold more, so always check your owner's manual.

3. How many gallons does it take to cover 1000 square feet?

Most labels recommend using 1 to 2 ½ gallons of water per 1,000 square feet.

For the pesticide labels, mostly we rate 1,000 sq. ft. The difficulty is that most people are unaware of how much liquid they are spraying per 1,000 square feet. Spraying without calibration risks underapplying material and not getting the desired results, or overapplying and wasting material and money. Here are few ways to help you calculate it easily.

  • First, only use water in your sprayer, then fill to the measured mark on the side of the sprayer. On a one-gallon sprayer, this should be the one-gallon mark, and on a two-gallon sprayer, this should be the two-gallon mark. A "flat fan," even-spray tip, rather than a cone or "hollow circle," is the optimum tip for flat surface treatment.
  • Second, spray the 1,000 sq. ft. area with the sprayer you filled with water. Spray the entire area. In case it run out before covering the 1,000 sq. ft. area, it means you applying too heavily. Start a new with a lighter and faster application. One gallon of water is the bare requirement for a 1,000 square foot area.
  • Third, check the sprayer volume measurement after you've completed spraying to discover how much water is left in your sprayer. Calculate how much water you used to cover 1,000 square feet by subtracting this amount from the original volume.

For example, the amount of water you used to cover 1,000 square feet was ½ gallon. If the label specifies 4 oz/1,000 sq. ft., then you try to mix 4 oz. with ½ gallon of liquid and spray the 1,000 sq. ft. You could have used less or more, but the idea is to figure out how much water you used on a 1,000-square-foot area.

4. Are backpack sprayers safe?

Of course Yes!

Backpack pesticide sprayers are excellent garden equipment for administering pesticides and herbicides over areas. The majority of current sprayers have exceptionally high safety factor. Even many manufacturers prioritize safety when researching the sprayer feature. A few safety concerns are frequently considered, such as its easy to use, safety button, or the anti-leaking liquid while operating it,...However, to use it safely, user need to follow some operating precautions, such as

  • Always use protective equipment such as eye protection, chemical-resistant gloves, and coveralls, as well as chemical-resistant clothes and a respirator as necessary.
  • When mixing pesticides for use in a backpack, follow the instructions on the pesticide label sprayer. Use pesticides at the manufacturer's suggested rates.
  • When loading the backpack sprayer, pour the pesticide mixture through the filter basket.
  • Never use flammable liquids, acids, or caustic because of their inherent danger.

Types Of Backpack Sprayer

There are two common types of backpack sprayers: a piston pump and a diaphragm pump.

  • A Piston pump: Piston sprayers have a cylinder housing in which a piston rotates up and down to create pressure when the pump is turned on. Most piston models have a maximum pressure of 90 psi. Due to its higher pressure, they are best use for long distances. It work well on produce finer droplets or a mist that covers the area well. They're perfect for spraying up into trees or larger bushes and shrubs because of the distance and finer droplets.
  • A Diaphragm pump: Diaphragm pumps have a flat diaphragm that is kept together by screws inside a housing. The diaphragm stretches up and down to create pressure when you pump. This one can reach up to 60 psi. Because there is no touch with the cylinder wall, these pumps are more robust. When spraying weeds, fencelines, and driveways, diaphragm pumps produce larger droplets that are better at getting the spray onto your target and avoiding drift.

Tank size

The size of the tank is one of the most important things to look for in any type of product, whether it’s a cheap backpack sprayer or a more expensive one. Most devices designed for commercial use feature a four-gallon tank, enough to cover the area of a small vegetable garden, lawn, or backyard.

On the other hand, products designed for industrial use will require bigger tanks of 20+ gallons as they need to cover a significantly larger surface.

No matter the size of the tank you choose, make sure it is translucent to easily see when it requires a refill. Also, look for items made of sturdy materials and with secure locks that won’t leak the chemicals out, causing rashes, irritations, or even burns on your skin.


The weight is critical factor that need to consider because the sprayer is worn on the back. Especially if you use it for a long time. Backpack sprayers are supposed to be light, the weight of your sprayer will be determined by the size of its tank. When completely loaded, most backpack sprayers weigh between 15 and 45 pounds. More capacity is beneficial, but it must be balanced against the sprayer's weight. Some people will find operating a machine with a total weight of 40 or 50 pounds too difficult.

Pump sprayers or battery-operated models?

Most sprayers with small-sized tanks of 2-4 gallons will require you to push a pump to release the substances through a hose. These products are the most popular because they are used to cover medium surfaces.

However, sprayers used for industrial purposes or needed to cover a large area will require the help of a battery that makes pumping easier, without causing hand fatigue when operating them. Usually, the battery is rechargeable and lasts for a couple of years, depending on how often you use the sprayer.


Nozzles, hoses, and pockets for storing all accessories are key elements of a good sprayer. They help regulate the pressure and allow you to choose between a fine mist or a full stream, depending on the type of surface you need to spray.

It would be best to store all these accessories with the sprayer to occupy less space and deliver a compact design. Thus, try opting for sprayers that feature special pockets and compartments for batteries, hoses, and nozzles.

There nothing worse than catching sight of weeds smoothing out your garden, lawn, and yard. Despite all your efforts they just seem to multiply faster than you can remove them. If this sounds familiar, I hear you…, but it doesn’t have to be this way.

With the best pressure sprayers, you can stay right on top of weed control, and make enough time to sit back with a cold drink and enjoy the fruits of your labor.

And that’s our aim… to break down the different types of pressure weed sprayers on the market, provide you with step-by-step guidance on how best to use them, and share our Landscaping expertise on the best models to buy to fulfill your requirements.

Choosing The Right Pressure Sprayers 

With such a wide variety of weed killer sprayers available on the market, choosing the right one requires some serious research and thought. In this buyer’s guide, we’ll take a look at the different types of sprayers you can buy, along with essential features that you should look out for. 

Backpack Sprayer 

Backpack sprayers are exactly that, mounted on your back, allowing you to carry a tank full of herbicide while you move freely as you work. As all the weight is directly on your back, these weed killer sprays are the most comfortable, especially when you do lengthy tasks.

The carry straps are a key feature, ideally, they are wide to prevent cutting into your shoulder, or better still padded in some way. They need to be strong and durable to hold the weight of a full tank and you need to look for connectors and adjusters that will stand regular use.

Like all pressure sprayers, the backpack design is fitted with a pump that usually requires manual actuation. The pump creates a pressure build-up inside the tank. It’s this pressure that forces the liquid through the spray head when the trigger is pressed.

You’ll also find a few models that have battery-powered backpack sprayers where the battery does the pumping for you. Generally, they are larger in size, making them perfect for medium to large-sized gardens or clearing out large areas of weed. 

Tank Sprayer

Available in both manual pumps and battery-powered versions, tank sprayers are free-standing units, with a handle that allows you to carry the tank from place to place as you work. Some models have a carry strap and the tank sits on your hip or your side. This limits mobility compared to a backpack sprayer, but it’s fine when working for short periods or covering small areas.

They are most often a cylinder shape, with an applicator wand attached to the end of a hose. You hold the wand in your hand and fire the trigger to release the spray.

Tank sprayers can be an excellent option for people with a tight budget as they tend to be cheaper than backpack sprayers.

Hand-Held Pressure Sprayer

Hand-held are the smallest design of pressure sprays, and are good for use in the garden, greenhouse as well as indoors when fertilizing, or applying insecticides. Although they can have many other useful applications around the home and garden.

Generally designed with a small pressure pump and a gun spray trigger they can be used single-handed.

Size and Capacity

While it’s obvious to want something compact and portable, you need to purchase a tank that allows you to be efficient and practical when working in your yard. So tank capacity is a major consideration.

Even within the different types of garden sprayers, tank capacity varies. You’ll find sizes ranging from 1 liter up to 25-gallons.

Obviously the smaller the product the lower the price, but don’t go into a purchasing decision based solely on price. If you buy a tank that is too small, uncomfortable, or poor performing, you just won’t use it and will have wasted your money.

Size Guide:

Hand-Held Sprayer: Aim for 1-2L, anything bigger than this starts to get a little tiresome on your wrist. If you are doing shorter periods of work like spraying a small area or feeding indoor plants this is the product to go for.

Tank Sprayers: This is the mid-size option. In most cases they will be between 1-4 gallons, anything larger than this will be too heavy to work with and feel comfortable. Most models will in fact be 1.5-2 Gallon.

Backpack Sprayers: These are the best choice for 3-7 gallons. Anything heavier than this will only be suited to those stronger users or people who use the backpack sprayer regularly and are accustomed to carrying this kind of weight around.

Best backpack Weed Sprayers

1. Field King Max Backpack Sprayer 4Gal

Field King Max  Backpack Sprayer

The Field King Max Back Pack Sprayer takes our top spot for all-around best tank sprayer. It has a solid manual pump system and is the most comfortable backpack on the list. Fitted with an internal pump that can offer 150 psi of pressure allowing for 30 ft of spraying distance. This system also has a built-in agitator, which is essentially two fans that blend the tank content as you pump, which I really find useful if using powder or fine granular ingredients.

As you would expect from a premium product, the wand is fitting with an in-line filter to protect the nozzle head from debris or power blockages. As a supplementary protection feature, the tank has a filter basket that you can place across the tank aperture to prevent large particles from falling into the tank during refills.

The shaft of the spray wand is made from stainless steel giving it a more durable feel than most of the plastic molded wands on our list. Plus you get a set of 4 interchangeable spray heads allowing you to choose the spray pattern to suit the job. The pump handle can be adjusted to suit left or right-handed actuation.

Finally, the unit features a full harness, including padded back protection, made from a breathable fabric. There’s a waist strap to help secure the tank on your back and I managed a long session with this tank and could have continued working for some time without any problems. The product is shipped pretty much pre-built, all you will need to do is attached the pump handle and spray wand.

Battery Powered Model: It’s worth pointing out this product is also available in a battery-powered version, linked above. This is another great product and the best battery-powered backpack sprayer on the market in our opinion.

I have a personal preference for the manual pump models. For the simple reason that you save a little bit of weight and avoid potential issues with batteries running low on me whilst I’m working. Having said that, you will get an impressive 50 gallons worth of spray-time out of the Field King lithium batteries.

2. Roundup Backpack Sprayer 4Gal 

Roundup Backpack Sprayer for Fertilizers

This 4-gallon Roundup Backpack Sprayer model no. 190314 provides plenty of tank capacity to get a lot of weed prevention under your belt. Designed specifically with herbicide in mind the manufacturer has just about all bases covered.

It features a heavy-duty poly wand with a shut-off valve with a comfort grip. You get a built-in spray lock for continuous spray, which is a really useful function to have when working with large areas. The design incorporates an in-line filter to keep dirt and debris flowing into the spray head and clogging it.

Plus the gaskets and seals as you would expect are designed for use with chemical liquids including herbicides, allowing for safe use with weed killers. You also get 4 different interchangeable nozzle heads to suit the spray pattern you require.

This backpack-style pump sprayer is supplied with really comfortable padded straps, which makes spraying for extended periods less tiresome. There’s also a waist belt to provide you adequate lumbar support and reduce back fatigue while working. 

It’s well thought out and would be a good fit for even the tallest of users. I’m 6’3″ tall and I wore this backpack for a few hours and it was really comfortable. So what about the negatives? Well, none in our experience.

  • In-line filter to protect the nozzle
  • The waistband provides lumbar support
  • Comfortable padded straps


  • Not as well built as Field King Max

3. Husqvarna Backpack Sprayer 4 Gal

pressure sprayer

So Husqvarna is a well-known and very reputable brand in the garden tools category and this tank lives up to our expectations. I kind of knew what I was going to get, and I got it! A well-built, functional backpack sprayer that fires at 150 psi to reach nearly 30 ft of spray distance and provides enough power for a consistent spray pattern.

Built for use with liquid concentrates and powders the tank system features a re-enforced 50″ section of hose for a good range of motion. The want is stainless steel and the kit provides 3 different nozzle heads to adjust spray patterns.

Overall a good pressure pump sprayer and one I am happy to recommend. In our test, it was not as comfortable as some of our other models and lacks one or two features.

Customer Reviews: Scoring an average 4.5/5 across all major retail platforms and forums this product is appreciated for the build quality you would expect from Husqvarna,


  • Well built from a highly regarded brand name
  • Solid feel and good spray pressure


  •  Not quite as comfortable as Field King or Roundup
  • Lacks a few features

4. Chapin Backpack Sprayer 4Gal 

Chapin 4Gal Backpack Sprayer

The Chapin 61800 4Gal Backpack Sprayer is a great low-cost backpack sprayer. It comes with padded shoulder straps that provide decent lumbar support, making it relatively easy to carry it around, even with a full tank. 

A 3-stage filtration system traps any debris, preventing it from clogging the unit while you’re working, this includes a basket filter for the tank aperture. It has an applicator wand with a cushion-grip and poly shut-off mechanism, which can be easily taken apart for cleaning out debris. Plus you get three different nozzles to adjust the spray pattern

While this pump is not as powerful as our top pick on the list I still got the spray to reach 20 ft which is more than enough for general use around the yard and garden.

The shoulder straps have average quality, but still good enough to get you through a few hours of work. So it’s not the best backpack sprayer in the world but for around half the price of our other backpacks it represents very good value for money, and I would be happy with it for light or occasional use.

Battery Powered Model: The good news is, there is also a lithium battery-powered model available in the Chapin 4Gal Backpack. There are some reported issues around the battery quality, so a good product, but when you’re spending well over $150 on an electronic piece of kit, there’s no point taking chances!

Customer Reviews: Customers who purchased this product report a very fair 4.4/5, which demonstrates their general opinion that this product is great value for money.

  • Value for money
  • Good for occasional use
  • Includes decent features


  • Not in the same league as some other product on our list

5. Solo 425 Backpack Sprayer 4 Gal

Solo 425 backpack sprayer

The Solo 425 is on our list as a great versatile product available in 3 or 4-gallon tank sizes, with a manual pump, battery-powered pump, or gas-powered pump. Plus, this is a product that’s widely available in most regions, including America, the United Kingdom, and Europe. With that level of options and as a great product that’s and so well distributed, I had to feature it!

The model I am featuring here the Solo 425 has a manual piston pump capable of producing 90 psi which will shoot a good 20ft of spray. More than enough for domestic use. The pump handle is ambidextrous meaning it can be used on the left or right-hand side of the pump.

It’s a very good option for home use as a weed killer or fertilizer spray. It doesn’t generate enough pressure for too many other applications. It does not match up to our winner’s specifications, but in many regions, this is the best backpack pump on the market and I would be happy to recommend it to our readers as a machine I would happily use in my gardens.

Battery Powered Model: The Solo 416 Li is a Lithium battery-powered model. It features a 5-gallon tank that can feel a little top-heavy.

Best Tank Sprayer

1. Scotts Battery Pump Sprayer 2Gal

Scotts Battery Powered Pump Zero Technology Sprayer

There’s not much to split the Scotts Battery Powered Tank Sprayer from the second place Smiths Contractor Tank Sprayer for the top spot. My preference is to usually stick to manual pump mechanisms to avoid any technical failures or running out of power mid-job. However, in the case of Scotts Tank, I am making an exception. In the short amount of time, I’ve used this product it’s been very good indeed. One of my colleagues has also been using this product at home for quite some time and it sings its praises.

So…my own bias aside, Scotts Battery Tank has to take the top spot, as it delivers on build quality, features, and a great reputation for a battery-powered sprayer. You will pay around an extra $40 for this product, but if you want a battery-powered unit then it will be worth the extra money over the long run.

Expect to get 12 full tanks with a single battery charge, with a re-enforces PVC hose and 3-in-1 nozzle settings for fan spray, stream spray, and cone spray. It’s comfortable to carry and produces a great spray pattern without dripping.

2. Smith Contractor Pump Sprayer 2Gal

smiths contractor tank sprayer

The Smith 190216 2-Gallon Sprayer is good for Lawns, Gardens, and also suitable for commercial use. It’s really well-built with plenty of features with 1, 2, or 3 Gallon models in the product range. I was really happy with the build quality and performance and it was a really close second to Scott’s battery-powered sprayer.

This unit has a commercial-grade polymer wand, which is chemical resistant. The trigger handle incorporates an in-line filter to protect the nozzle from dirt ingress, plus you get 5 interchangeable nozzles as standard.

The sprayer is easy to carry by the handle and comes with a professional shut-off valve. In addition to this, the shoulder strap is another convenient addition that makes portability easy and reduces fatigue when you handle it in your hands. 

Additionally, it comes with Viton seals and gaskets, and a professional shut-off lock. The Viton seals of the pump make this sprayer resistant to chemicals. You won’t have to worry about any accidental spills after opening the tank thanks to a robust pressure release valve, which automatically vents at 60 psi as a nice backup safety feature. My only gripe is a 1-year warranty. Okay, the build quality is great, but things can go wrong. But still, a great price so well worth buying.

Customer Reviews: Achieving an overall online customer score of 4.6/5 there’s no doubt this is one of the most popular tank sprayers on the market.


  • Excellent build quality

How to Use Weed Killer Sprayers: Step-by-Step 

  1. When spraying chemical solutions it is always advisable to wear protective clothing to prevent chemicals from making contact with your skin
  2. Before you attempt to unscrew the cap, lid, or top of your tank sprayer before opening the pressure valve, release any pressure already trapped inside the tank.
  3. Turn the cap counter-clockwise to open and remove the pump mechanism
  4. Fill the tank with water up to the required level. Be sure to read the herbicide manufacturers instruction on dosage and dilution ratio before adding any weed killer, fertilizer, or other concentrates
  5. Pour the concentrate into the tank and reseal the tank lid and tighten until you get an air-tight seal.
  6. Grip the tank pump handle and slowly lift to extend the pump and push back down to begin to create pressure within the tank.
  7. You will know the tank is pressurized when the pumping motion becomes more difficult and you feel noticeable resistance
  8. Take the applicator wand and point the nozzle towards the floor. Using your protective gloves, use your hand to twist open the nozzle and gently press the trigger to perform a ‘test’ spray, to check the tank pressure and the spray pattern. Adjust as required.
  9. Wearing your protective equipment including a respiratory mask, gloves and goggles deploy your spray in a downwind direction, until the area is treated.
  10. Remove the lid from the pump sprayer and rinse it out thoroughly using your garden hose.
  11. Dispose of the remaining water in a location where it won’t affect drinking water or accidentally kill your plants
  12. Store the sprayer in a covered location, out of the reach of children, when not in use

When Is the Best Time to Spray Weed Killer? 

Weeds are a seasonal phenomenon, and when they return, they’re stronger and seem to have multiplied over winter after the seed heads have dispersed, or the rhizomes crept further across your land. So when is the best time to kill weeds and does it actually matter?

The short answer is to kill them before they shed seeds, but let’s get under the skin of this point. In the introduction of this article, I promised to save you time so you could enjoy a cold drink and gaze with satisfaction on the fruits of your labor.

Time of Day

Early morning dew can dilute weed killer of cause run-off, meaning it hits the soil and not the plant. In late evening plant growth slows down so absorption rates decline and again you may experience dew through the night.

The optimum time to buckle up your backpack sprayer is mid-morning after the foliage has dried of any moisture or dew and before the sun is high enough to make your life uncomfortable while you work.

How Often Should I Spray Weed Killer? 

You can chase weeds around your garden like chasing shadows if you think it’s fun. But to be effective I can do two major weedkiller treatments, one in spring and one in fall.

In fall or autumn, ideally October. This is when weeds are preparing for winter and go through a process of storing as many nutrient resources as possible to not only survive the winter but come out of it ready to flower and set seed. It is similar to thinking about how hibernating animals prepared for winter.

Spray early October when the weeds are like sponges soaking it all up, use a post-emergent spray for this treatment. if I’m applying the treatment to areas of lawn etc I may also apply a pre-emergent weed killer 14 days later, that will sit overwinter and help prevent seed germination in early spring.

Pre-emergent is only really for lawns or areas where you get weeds like crabgrass. If your shooting for perennial weeds, then you are better off waiting until they show their location in spring. When they start to grow, target them with a strong weed killer spray leave it for 14 days. Rake off any dead thatch. If you are dealing with really thick dense weeded areas you may choose to go again with a second treatment.

However, you tackle it, the best time to spray dandelions and similar broadleaf weeds are just before they have a chance to shed seed, otherwise, you will be tackling double the work next season.

Throughout any summer growing season you will get weeds germinating from the soil that has been turned over. Personally, I would not be chasing these guys with a pressure sprayer. I would handpick them, hoe them, or dig out tap-rooted perennials.

You should always spray your weed killer cautiously. Using too much can lead to airborne droplets of weed killer damaging flowers beds and grass present in your yard, so make sure that you’re applying the product properly and in the right amount. 

It’s best not to mow before and after treating weeds. You should also avoid using sprinklers prior to or just after spraying, as weed killers need to sit on the weeds for an extended period to kill them effectively, and most sprays can get washed off when subjected to water. 

Best Tank Weed Sprayer Conclusion 

Getting the right weed killer sprayers will ease your workload and make lawn care less cumbersome. Plus, you’ll get to work more efficiently, and who wouldn’t want that, right? 

After much deliberation, I found the Field King Max Backpack Sprayerto be the perfect choice for an all-in-one weed killer sprayer. 

It has an impressive and functional design, very comfortable to wear for long periods of time, and it feels and works like it’s built to last.

For those looking for a smaller handheld tank sprayer then Scotts Battery Pump Sprayer is an excellent choice and a product I have no hesitation in recommending to you.

While looking at sprayer reviews pays off, you should note that each user has different needs. Still, we’re confident that our top picks tick all the right boxes, and you’ll find the perfect match for your lawn no matter what you choose.

Frequently Asked Questions

What are Post-emergent weed killers?

Post-emergent weed killers control existing weeds, and they can be systemic or non-systemic. Systemic weed killers work by moving through plants to their roots, and they’re most effective when the plants are actively growing. Non-systemic weed killers, on the other hand, damage plant tissues, and they can be applied at any time of day.

What are Pre-emergent weed killers?

Pre-emergent weed killers are also effective when applied at any time of day. These weed killers create a chemical barrier in the soil that prevents weeds from germinating.


Backpack sprayer scotts

No doubt you have a ton of outdoor projects to tackle this summer—and a laundry list of things to buy, from raised garden beds for fresh summer veggies at your fingertips to landscape edging to spiff up your property. But to keep weeds and pests away so that greenery thrives, it may need more of a nudge than Mother Nature can give. A garden sprayer is the easy answer for maintaining plants yourself so you won't need to shell out a fortune for a landscaping service. Whether you want to take the easy route and get an attachment for your new garden hose, or you need something more heavy-duty, read on for our top recommendations for garden sprayers that work for every backyard and budget.

What to Consider

The place to start is with the amount of ground you need to cover. You’ll want a sprayer large enough that won’t need to be refilled every 20 minutes, but not something that’ll needlessly weigh you down. Non-professional garden sprayers are typically made of polyethylene plastic and stainless steel, with tank sizes ranging from 1 gallon or less, up to a 4-gallon backpack or wheeled garden sprayer.

The most basic sprayers are manual pumps, and there are also higher-end battery-powered options. There are many features to consider that depend on the style of sprayer you choose. But generally speaking, things like adjustable or extra nozzles, locking triggers, telescopic wands, and ergonomic handles are good to keep in mind. Also, note that some garden sprayers aren’t made for acid-based solutions or other corrosive chemicals.

How We Decided

All of the garden sprayers we feature are from top brands, with ratings of at least four stars, and during our research we combed through countless customer reviews and consulted expert gardening sources. We cover every major style used by non-professional gardeners—from small handheld options ideal for potted plants to large-capacity sprayers for large yards—and offer products to consider across price points, from value-packed to premium picks.

Best Compact Handheld

Chapin Multi-Purpose Garden Sprayer


Garden sprayers with a simple design, like this one from Chapin, are perfect for treating potted plants, as the task doesn’t require a telescopic wand. The company knows a thing or two about how to make top-notch lawn and garden products, as they've been in business for more than a century. 

The 48-ounce compact sprayer has a sturdy translucent take with an in-tank filter and features a comfortable ergonomic handle and a tight-fitting lid, plus it’s designed for use with the most common fertilizers and has simple twisting nozzle. Its vertical and horizontal streams reach distances of more than 23 feet. Also, you can't beat the price: under $17 at the time of this writing. 


Best Value for 1-Gallon

Chapin 1-Gallon Garden Sprayer


It may not look as eye-catching as some others we cover, but it does the job—and does it well. It features a translucent 1-gallon tank and funnel top, along with a comfortable handle and an in-tank filter. Its spray flow rate ranges from .4 to .5 gallons per minute, and it can be filled with a range of commonly used pesticides, fertilizers, and weed killers. If you have a larger area to cover, the garden sprayer is also available in 2- and 3-gallon sizes.


Best Upgrade for 1-Gallon

Itisll Pump Garden Sprayer


If you’re looking for a 1-gallon portable garden sprayer with a telescopic wand, this option is an excellent choice. It features a translucent container made of durable polyethylene plastic and a brass wand that can reach up to 3 feet away, along with a twisting nozzle with a 360-degree rotating head. 

There’s an ergonomic handle on top that can lock the trigger for long spraying sessions and a safety valve that automatically lowers pressure if it exceeds 2.5 bars. 

The handy, adjustable carrying strap is a nice extra. Keep in mind that this sprayer isn’t intended for acidic or corrosive solutions.


Best Value for 2-Gallon

Solo Handheld Garden Sprayer


There’s a lot to like about Solo’s 2-gallon garden sprayer. It’s well-priced and lightweight, with a translucent high-density polyethylene tank and an easy-to-fill funnel top. It features a 28-inch wand said to be “unbreakable” (and which has a locking shutoff valve so you can take a break from your task), plus four nozzle positions and chemical-resistant seals.

There’s also a spot to set the nozzle when you aren’t using it and a removable shoulder strap. Do note that it can’t be used with acid-based solutions.


Best Upgrade for 2-Gallon

Smith Performance Garden Sprayer

This 2-gallon garden sprayer is a significant step up from the Solo in price and features. For starters, it has a high-efficiency pump, a trigger lock to keep your hand from cramping while spraying, and an in-line filter with ample surface area that prevents clogging and is easy to clean. 

Other highlights include durable Viton seals and gaskets and a 21-inch stainless steel wand, plus four nozzles to swap out and a pressure relief valve for extra safety. This garden sprayer is a customer favorite, with an average 4.6 stars from nearly 1,200 reviewers.  


Best Battery-Powered

Scotts Lithium-Ion Battery-Powered Garden Sprayer


If you’re over manual garden sprayers and have more to spend, a battery-powered model is the way to go. This 2-gallon capacity model from the well-known garden-care brand Scotts has a lithium-ion battery—and you can fill the tank up 12 times before it needs to be recharged. There’s a 21-inch wand with a nozzle that has three settings—fan, stream, and cone spray—that has a designated storage spot. 

Other highlights include a pressure value, a shutoff with Viton seals to extend the life of the sprayer, and an in-line filter to prevent clogging that’s easy to clean. 


Best Value Backpack

D.B. Smith Field King Backpack Sprayer


Using a handheld garden sprayer isn’t efficient if you have a lot of ground. For larger yards, you’ll want something that holds more than 3 gallons, and the best way to haul it is on your back. This ergonomic backpack has a 4-gallon capacity and features an internal piston pump for powerful spray, along with a 21-inch wand and four nozzles to switch out, including an adjustable brass option, two flat fans, and a foaming nozzle. 

The backpack gets rave reviews from customers, with an average 4.7 stars from more than 3,400 reviewers.


Best Premium Backpack

My 4 Sons Battery-Powered Backpack Garden Sprayer

With more to spend, this backpack sprayer is top-of-the-line—a battery-powered unit that’s said to run up to 8 hours on a single charge, which equals roughly 200 gallons of liquid. Chances are that’s probably overkill unless you’re a professional, but it’s nice to know you can spend the better part of a morning or afternoon working without having to worry you’ll run out of juice. 

Other highlights among features on this high-end backpack include a stainless steel adjustable wand with a locking handle and a bevy of nozzle attachments, plus thick shoulder pads and organizational pockets for small items.


Best Garden Hose Sprayer

Ortho Dial-N-Spray Hose End Garden Sprayer


It doesn’t get any more straightforward than this cheap option, but the convenience of attaching the sprayer to your garden hose means you'll have to drag the hose around your yard. That said, the sprayer has an impressive 14 dilution settings to adjust the flow of concentrate to get the right chemical-to-water ratio. 

The attachment also features a large dial that’s easy to adjust, and there's a comfortable trigger, along with three different spray patterns. Another major plus is that weighs less than a pound.
