Weed Sprayer Versus Ordinary Garden Sprayer

Before anything else, you should know that not all garden sprayers are ideal to be used as weed sprayers. How so?

While all these sprayers are good to use with plain water, not all can tolerate chemicals. Hence, the difference basically relies on the type of material being used. Although, the design and the mechanism per se are true enough just the same.

Because of the nature of the solutions being used, it is best to keep a dedicated sprayer for weed killers. This will minimize the cross-contamination of contents. Any residue left from the previous solution might create an untoward reaction when mixed with another type of chemical. This can be potentially harmful not just to the plants, but to the user as well.

Different Types of Weed Sprayers

There is a wide range of styles of garden sprayers you can use for weed killing. Here are the most common types:

Handheld Trigger Weed Sprayer

This type of weed sprayer comes with, as the name implies, a trigger mechanism. With a simple squeeze of the lever, the solution is quickly dispensed out of the nozzle. This sprayer is meant to be carried by hand so it tends to have a smaller capacity. This makes it perfect to use for smaller gardens.

Tank Weed Sprayer

If you are out to cover a tad bit bigger lawn, then the tank sprayer is a great option for you. This comes in a larger capacity so it can well cover a wider ground. Since it is bigger and heavier, the tank sprayer conveniently comes with a shoulder strap. This makes it easier to carry around with you while you are spraying the weeds.

Backpack Sprayer

The backpack sprayer is another good option if you want to cover a large area but still with ample mobility. The sprayer here is attached to backpack straps. This makes the weight of the tank evenly distributed across your back. Hence, it is more ergonomic to work with.

Wheeled Weed Sprayer

This type of weed sprayer is perfect for users who have issues with mobility. More so lifting heavy objects. The sprayer is attached to a set of wheels. Hence, allowing it to have a large capacity tank without worrying about its transportability.

Hose-End Sprayer

This type of sprayer is quite unique among other types of weed sprayers. The sprayer itself is meant to be attached to the garden hose. All you have to do here is to fill the canister with the weed-killing chemical. Connect it to the hose-end of the garden hose. Once the faucet is turned on, the water will automatically mix with the concentrated solution. This said mixture will only be released when the trigger is activated.

Factors to Consider When Buying Weed Sprayer

You must always bear in mind that you are dealing with chemicals. Some might be organic while others can be a little too harsh for ordinary material to handle. Considering that, it is best to always be on the safe side. 

Make sure to use sprayers made out of reliable materials. Materials such as polypropylene and polyethylene plastics are among the most commonly used. These types of thermoplastics are designed to have good chemical resistance. Hence, you can guarantee that they are suitable to handle volatile substances like weed killers. Provided, however, that they are maintained at room temperature.

Tank Capacity

The garden sprayer is available in a good range of tank sizes. It can be as small as a quarter of a gallon up to as big as five gallons. 

The selection of the capacity of the tank should basically depend on the size of the work area and as well as your capacity to carry the load. If you don’t mind the weight, it is best to opt for sprayers with larger tanks. That way, you would least likely need to refill it frequently.

On the other hand, if heavy lifting is an issue, then it is rather safer for you to choose a capacity based on what you can only manage to carry. In this case, there should be some level of compromise here. You can choose to let go of the weight so that it won’t be too heavy for your body. Nonetheless, be prepared as well to allocate more time to prepare and refill your tank more often.


In relation to tank capacity, you should also consider that the bigger the sprayer, the heavier the load will be too. This is something definitely worth noting as this can directly affect your body mechanics. Carrying way too heavy objects can put you at risk for unnecessary strain, fatigue, and even injury. This is in no way ergonomic and healthy for you.

On that note, it is rather wise to choose a sprayer that is lightweight. That way, the device itself won’t further add to the weight of the fluid. Do make sure to take advantage of the availability of the straps. There are garden sprayer models that may feature shoulder or backpack straps. The provision of which allows you to efficiently distribute the weight.

Better yet, you can also choose weed sprayers on wheels. This type requires no lifting and so ideal for those with back problems and other physical restrictions. All you need is some push and pull action and you can bring your weed sprayer anywhere you want to. 


Nozzles come in different spray patterns that include full shower, mist, flat cone, center, soak, and more. Each has its own purpose. For example, the mist pattern is perfect for applying solutions to delicate plants. On the other hand, a soaker head is suitable for deeply hydrating a tree or a lawn. 

Aside from spray patterns, there are also some sprayer heads that offer functionality. For instance, a retractable wand enables you to access hard-to-reach areas. Hence, a perfect tool for treating weeds on corner spots and any other nook and cranny in your garden.

Having the option to interchange between different nozzles gives you better versatility. You can easily switch up depending on what the application calls for. Or, you can also use this feature to change a worn-out nozzle without the need to replace the entire weed sprayer. 


It is essential to give your weed sprayers a good clean every after each use. Doing so will help to keep your tool in good shape and condition. Hence, preserving the efficiency and longevity of the sprayer. 

It doesn’t have to be something too complex. You can simply drain the excess chemicals, give it a thorough wash, and then fully dry. Make sure to include the hose, the nozzle, and other components in contact with the chemical. This will prevent residue build-up and corrosion on metal parts. 


Mainly because we are dealing with chemicals, it is a must to take extra safety precautions. One of the most important things is to wear a respirator mask. When using weed sprayers, the droplets can be as minuscule as 1/1000 millimeters. It is super fine that it can easily blend in the air we breathe. So just imagine the probability of it reaching our lungs and causing damage in the long run. 

Our skin is also another thing that is widely exposed to chemicals when using weed sprayers. Some compounds are very irritating and can even burn your skin. On that note, always be careful preparing or mixing the solution. Wear gloves if you must.

Also, be mindful of where you put your hands at all times. When coming into contact with any of the chemicals, do NOT touch anywhere else, especially your eyes and face. Make sure to wash your hands immediately. 

If accidents should unfortunately occur, always rinse the affected area with clean running water. Then, consult a health professional immediately for proper treatment.
