Lawn weeds are those uninvited guests that compete with your yard for water, nutrients, and light, as well as foster diseases and pests. Regardless of whether you have green fingers i.e. the ability to make anything grow when healthy plants thrive in your garden, these pesky invaders thrive alongside them.
Using a weed spray and sprayer will make getting rid of the unwanted weeds much easier for you. Keep reading for my recommended sprayers to use around the house and what spray/solution to use for the type of weeds that you have.
This post is divided into 3 parts:
Types Of Lawn Sprayers
Choosing the best sprayer for your needs depends on a few factors. Consider your usage area (full lawn or garden), what you want to apply, and how often you plan on using it.
The most lightweight for small applications is the hose-end sprayer. These are the lowest price types of sprayers out there but will cover the least amount of area as well. I don’t like these for lawn applications unless you have a small area to treat and you have a garden hose hookup. But these are also easy to mix product in as most will have measurement lines for easy filling. I like The Andersons Refillable Multipurpose Hose-End Sprayers as you get 2 in the pack and can use one for herbicide and one for insecticide.
Hand Held Lawn & Garden Sprayers
The most common for homeowners is the handy handheld sprayer. Perfect for spraying product to gardens or killing weeds around the fenceline, driveways, borders, etc… These will be typically a hand pump to build up pressure in the sprayer or battery-powered that will offer a constant flow. Some will come with a shoulder support strap for easier carrying while smaller ones will just have a lock handle so you can carry it around.
I usually fill my 2-gallon handheld with a liquid weed killer and keep it around the garage during spring/summer. I like the Smith Contractor 2-Gallon Sprayer for this as it has a standing base to keep it upright and in-place.
For bigger gardens or yards, or if you don’t want to lug around a handheld, you should consider using a backback sprayer. They usually cost a little more than handhelds but are easier to handle yet holding more product so you can get the job done without having to keep refilling and mixing product.
These are also found as pump-powered or battery-powered and are usually 3 gallons up to 5.3-gallon capacities.
I like my Kimo battery-powered 3-gallon sprayer for use around the yard. It’s big enough where I can put down what I need and it’s not too heavy where I wake up with back pain the next day.
Okay, now for the bigger lawns I take care of I’ll use a tow-behind. These can be found most commonly in the 5-15 gallon range and up to 60 gallons for the big boys. I like the Chapin tow-behind sprayers and they also have ATV mounted sprayers as well.

When To Use Your Sprayers – Spraying Schedule
Make the most of your sprayer year-round for different applications such as pest control, fertilizing, and disease control. It’s recommended to have multiple sprayers for different applications such as herbicides and insecticides available at your disposal.
Early Spring (Feb-March)
This is the perfect time to get a new sprayer or clean out the one from last season. Use this time to put out a weed pre-emergent, early control for pests, and to fix and lawn diseases that may have started to form over the winter. But only do this if your lawn temp is over 55 degrees.
If you have not yet put down a weed pre-emergent, now is the time to do so in your lawns. For gardens you can use your sprayer for fertilizers and other nutrient boosters.
Spray shrubs and plants with an insecticide to control bugs. You can also spray your lawn to keep mosquitos and other insects at bay. Spot spray stray weeds that pop up. Keep spraying benefitial nutrients to your garden.
Good time for foundation spraying to keep crawling insects such as lawn spiders out of your house as they won’t cross the barrier you put down. Apply a good 2″ line of insecticide around the house.
Top 5 Weed Killer Sprays to use in a Sprayer
Tenacity Herbicide – Best Spray For Homeowners & Commercial
Tenacity is regarded as one of the leading herbicides in its segment, and is a supreme warrior against over forty-five broadleaf weed and grass species including Chickweed, Clover, Dandelion, Crabgrass, Yellow Nutsedge, Yellow Foxtail, and Nimblewill.
Tenacity is billed as a systemic herbicide, meaning it is absorbed and transported through the weed plant’s vascular system, killing the entire plant. Furthermore, it is designed to be used in cool grass lawns, and newly seeded or established turf.
Naturally derived from a naturally occurring compound produced by the Bottlebrush plant, Tenacity is regarded as a “Reduced Risk” product by the EPA (United States Environmental Protection Agency), and can be applied before or after seeding of tolerant turf grasses to prohibit weeds from germinating.
Brought to by Syngenta — a leading agricultural company, the active ingredient in Tenacity — Mesotrione is known for preventing Crabgrass seed germination, and kills broadleaf weeds up to six weeks after application.
Tenacity Application Rates
Tenacity can be applied with a herbicide sprayer and should be allowed at least six hours of drying time before any rain or irrigation occurs. It is also highly recommended that you use a spot treatment for dense areas to avoid causing damage to your lawn.
Tenacity may cause temporary whitening around the weed areas of the lawn, which typically returns back to normal color within three to four weeks. However, it is best to use Tenacity with a surfactant to prevent spraying the herbicide in the same area twice.
How to Mix Tenacity with Surfactant?
Lawn experts recommend using tenacity with a surfactant to improve weed control and allow the herbicide to stick better with the surface of the weeds. Mix half a teaspoon of Tenacity with around 10 teaspoons of surfactant with one gallon of water (1000 square feet coverage), and increase accordingly depending on the size of the area.
Next, add a small amount of marking blue dye to the Tenacity and surfactant mixture to see exactly where you’ve sprayed the herbicide. When applied to the turf, the dye will disappear within 24 – 48 hours and does not affect your lawn grass. Lastly, spray the mixture evenly across the lawn, and repeat the application in 10 – 15 days.

How to Use Ortho Weed B Gon Plus?
The ready-to-use formulas of Ortho Weed B Gon Plus are geared towards specific types or small patches of lawn weeds. To apply the ready-to-use Ortho product, you simply have to adjust the onsite trigger or spray nozzle for a wide or narrow spray, and spray at the center of the weeds.
The Ortho Weed B Gon Plus hose-end spray bottles attach directly to your garden hose, where the water once turned on mixes with the weed killer formula inside the bottle to be applied at the proper strength.
Mixing Ortho Weed B Gon Plus concentrate takes a little more effort, and is suitable for sprayers that come with a minimum one-gallon reservoir. To create the mixture, add approximately 2.5 ounces of concentrate to a gallon of water, and mix well. Then adjust the spray nozzle, and spray lightly over the weed affected area.
How Long Does Ortho Weed-B-Gon Plus Take to Work?
This depends on the type of weed, and the level of infestation. Ortho says that the Weed-B-Gon herbicide works almost immediately, when used properly. The best time to spray Ortho Weed B Gon Plus is when the weeds are actively growing, and in daytime temperatures above 45 degrees Fahrenheit, and below 90 degrees Fahrenheit.
The effectiveness of the Ortho Weed B Gon Plus is not affected by rain or watering for up to an hour after application, and it is not recommended that you apply it more than twice a year.

Lawn Weed Herbicide Spray Buying Guide
Local garden centers and home improvement stores stock a wide assortment of spray-on herbicides, making it a bit tricky to choose the right one for your lawn. To make the right choice, you will have to get “up close and personal” with the weeds growing in your lawn, and answer a few important questions.
What type of weeds are growing in your lawn?
First, the most important thing is to select a herbicide that is formulated to kill the specific weeds growing in your lawn. So, start by examining the unwanted pests to determine the type of weed such as whether they are annual weeds like crabgrass, seasonal weeds, or if they are harder to control weeds such as dandelions and nutsedge.
5 trusted websites that can help you identify weeds:
Can You Spray Weed Killer On Wet Grass?
If you are using a liquid weed killer product, it is recommended not to put it down on wet grass as it will dilute the effectiveness of the killing agent. You want a liquid product to have a good 1-3 hours before it gets watered in so you get the full benefit of it attacking the plant.
If you use a granular product then in most cases it would be okay to put it down on wet grass, as you will want to water it in to activate the product.
Is your goal to prevent weeds from growing or eliminate those already growing?
Before getting into whether you’d like to prevent or eliminate weeds, you should educate yourself on the different types of herbicides.
Post-Emergent Herbicides – these herbicides are some of the most popular substances used for weed control, and basically designed to prevent weeds that are already up and growing. When sprayed on weed plants, they work by penetrating throughout the plant system, right down to the roots, and killing them.
But it is worth mentioning that most post-emergent herbicides are “nonselective”, meaning that they can harm both the weeds, and the desirable plants in your lawn, hence should be used with caution.
Post-emergent herbicides are a great choice for use over patios, driveways, walkways, but you wouldn’t want to use a hose-end sprayer and broadcast a nonselective herbicide over a lawn filled with prized flowers or across a vegetable garden. You can however try using a precise spray to target only the unwanted weeds in these precious areas.
Pre-emergence Herbicides – just like the name would suggest, pre-emergence herbicides when sprayed prevent weeds from emerging in your lawn. The chemicals in pre-emergence herbicides do not necessarily affect germination, but rather stop the growth of new root cells in baby weed plants.
These pre-emergence herbicide chemicals do not affect established plants, as they already have a developed, healthy and hearty root system. Pre-emergence herbicides require water to activate them, and direct the chemicals down to the root system of newly sprouted weeds.
Pre-emergence herbicides can help control and eliminate several different types of weeds of your lawn, especially crabgrass. If you encounter weeds in specific areas of your lawn every year, then spraying a pre-emergence herbicide can prevent future occurrences.
How much liquid herbicide will you need?
This completely depends on how big or small the area is, but generally, a ready-to-use herbicide that does not have to diluted with water works best for smaller areas. If you are looking to control weeds spread across a broader area, then you may want to consider a more concentrated product.
What is a surfactant, and how does it work?
Surfactants are regarded one of the most versatile products in the chemical industry. The word “surfactant” is derived from the words “surface active agent”, and is used in a wide range of applications ranging from agriculture to household detergents.
When it comes to herbicides, surfactants serve as a wetting agent to increase the penetration and overall effectiveness of almost any herbicide. Some herbicides come fully loaded to include a surfactant, whereas others may require you to add surfactant to increase their activity.
What is the best time to apply spray weed killers?
Given that not all herbicides are formulated alike, they need to be applied at different times of day for optimal effectiveness.
The best time to apply systemic lawn herbicides for broadleaf weeds is within certain temperature ranges 70-90 degrees but is not that effective when temperatures are too low.
Refrain from applying weed killers around midday or early afternoon in the summer, as the herbicides may quickly dry out the leaves, resulting in less herbicide absorption. Pre-emergence herbicides can however be applied at any time of the day, given that they work at the soil level to prevent the weeds from growing.
Safe use practices for liquid weed killers
Weed plants are part of nature but can prove to a disaster for many lawns. When used properly and safely, herbicides can be an effective weed control solution. Contrarily, a careless approach to weed control can lead to damage to desirable plants and may be harmful to you and others.
1. Always read the label – just like any other chemical-based products you may use, it is important that you read the label on the herbicide container, and understand the instructions before use. Some labels may be daunting to read, given their length, or fine print, but you should still view the entire label, whether on the container or online on the manufacturer website.
2. Use protective equipment – even if you are using an organic herbicide, it is good practice to use protective equipment such as gloves and safety glasses.
4. Understand “signal words” – these words are required by the Environmental Protection Agency (EPA) to warn users about the levels of toxicity of herbicide. For example, the word “caution” indicates that the herbicide is slightly toxic or relatively non-toxic, hence may cause acute illness if inhaled, swallowed or exposed to the skin.
Herbicides with signal words “danger” or “poison” should be handled with extreme caution, as they can cause severe damage or death in worse cases. And some herbicides may contain more than one signal word, which indicates that it may affect the body in different ways such as when exposed to skin, and if inhaled or swallowed.
Not all unwanted plants are weeds, but there are certain weeds that can become invasive and problematic in your lawn. While you can use any of the herbicides mentioned on this list for effective and efficient weed control, there are other things you can do to speed up the process, and bid adieu to weeds permanently.
You can start by adding mulch over the weeds to block the sunlight to the area to prevent them from germinating. Another great weed control option is to manually pull them out including their roots. And if you are feeling hungry, you can even eat some weeds when they are young and tender such as purslane, amaranth, and lamb’s quarters.
Hi, Alex Kuritz. here. Growing up I remember that my family had one of the best lawns in the neighborhood. Richly green and lush. I did a lot as I grew up in terms of caring and tending for not only my family’s lawn but also my neighbors. I can say I have years of experience, and I am here to share it with you.
Please leave your comments below as I try to respond to everyone that has questions.
