When Is the Best Time to Spray Weed Killer?
You are going to have weeds to eradicate every year. They tend to come back each season and are stronger, and there are more of them. Therefore, you might think you’re doing something incorrectly.
When is the best time to kill weeds? Does it need to be hot outside, or should it be cold? Which weed killer is best for spring?
These questions are likely on your mind, and it is time to find the right answers. You are going to find out when to spray based on the time of year and various environmental factors.
The Season
It is often best to spray weed killer in the fall and spring. You’re going to hit the weeds with your pre-emergent in spring so that they don’t have a chance to grow. Then, in eight weeks, you can use a post-emergent spray to kill the more intrusive ones.
Fall also works well because the weeds are going to hibernate for winter. They’re more vulnerable right now, so they can’t survive the winter if you spray post-emergent chemicals. Just remember that they aren’t going to wilt or die immediately.
Time of Day
The time of spraying affects how it performs, too. Spray in the morning or afternoon when it’s warm. When it’s cooler, consider early afternoon for the best spraying.
How Often Should I Spray Weed Killer?
It’s important to understand that if you use too much weed killer, you can kill the lawn. Therefore, you should only spray the weeds appropriately. Make sure that you are treating them when they’re actively growing.
Spray and treat in the spring, such as during the month of April. Continue with your regiment into early October. Remember, some weeds don’t surface until much later in the year.
Many weed killers work on contact, so it must make direct contact with your weeds. In some cases, that means spraying again in May or June. Then, most of the weeds are emerged and thriving.
You can choose a pre-emergent spray. It is sprayed on the ground and kills the weed when it comes up.
Ensure that you know the type of weeds you have. Mature weeds are harder to kill. Plus, some have coverings of wax or hair to help them thrive when chemicals are sprayed.
It is best not to mow after and before treating for weeds. You may also want to stop using sprinklers so that the weed killer has enough time to kill from within. Most sprays have to sit on the weed for an extended period, and rain or watering can wash it off prematurely.
How to Use Weed Killer Spray?
The first step to using weed killer spray effectively is to know the target. You’ve got broadleaf, sedge, and grassy weeds.
Broadleaf versions have wider leaves and a branched step. They include dandelions, white clover, poison ivy, and more.
Grassy weeds only have one seed leaf like grass. Examples can include crabgrass, rushes, and goosegrass. Sedges are similar to grassy weeds, but the leaves have a triangular shape, such as with yellow nutsedge.
Then, you have to consider whether it’s a perennial or annual weed. Annuals only live for a season, so they’re quite easy to control. However, perennials come up each year and use the same root system.
When you know what weeds you have onsite, you can read the label of the weed killer and make sure it is going to work. If you’re using a sprayer, you want a liquid herbicide.
You’re also going to require a sprayer. There are many styles on the market, such as backpack sprayers, hand-held versions, and those that attach to the backs of ATVs. Each person has their own preferences.
The hand-held sprayer is often smaller and holds less. That way, you can carry it longer distances without fatigue. However, the backpack version sits on the back, so it is more comfortable to wear for extended periods.
Booms are the ones that attach to the ATV and other yard equipment. These allow for more extended use when you have to travel far away from the house. Plus, they can hold more products because they are often larger.
Most of these sprayers require you to pump them up so that they get to the right pressure. This means they are going to spray directly where you aim the wand. It is imperative that you follow the instructions that come with your sprayer to ensure that it works correctly.
Such sprayers can also be used for other things, such as power washing and spraying fertilizer. However, you should never use one sprayer for multiple products. Instead, buy multiple sprayer systems and label them so that they only ever contain the same chemicals.
Conclusion
When it comes to picking the best weed killer sprayers, we think the Field King brand is ideal. The backpack sprayer doesn’t leak from the pump, so you don’t get chemicals down your back. Plus, it goes up to 150 PSI from the piston pump.
You’re going to find it easy to change the seals as needed. Plus, you also get four different nozzles for any job you might require. This sprayer also looks professional and has a long wand so that you can spray hard-to-reach areas.
