You put a lot of energy into maintaining the lawn. So, you probably don’t want weeds where your garden should be. But can you put weed killer on wet grass, or will that cause a problem? And how do you keep weeds off of your lawn otherwise?

You can spread granular weed killer on damp grass. However, you have to leave the lawn alone for at least 48 hours afterward. That’s because moisture helps the herbicide stick to weeds. But too much water can wash the chemicals away.

How to Keep Weeds Out of Your Yard

Clearing your yard of weeds can be tricky. Each plant species requires a different approach. Plus, you can damage other foliage in your yard if you’re not careful. So, here are three easy and natural solutions:

#1. Pour Boiling Water Over Weeds

Boiling water can help kill weeds instantly. And you don’t need any other ingredients. Simply pour hot water on the weeds’ roots to prevent them from growing. You can repeat this process as many times as it takes.

#2. Spread Some Soap

Most soaps contain oils that can suffocate plants and weeds. The oils also break down waxy or hairy leaves and stems. So, add a few drops of liquid hand soap into a water bottle and spray wherever you need it. Then wait for nature to take its course.

#3. Use Your Favorite Weed Killer

Chemical weed killers can work wonders where natural remedies fail. That’s because they stop weed growth at the root while also making the dirt less attractive to new plants. But use chemical weed killers wisely or else kill healthy plants instead.

NOTE: You can’t use certain weed-killing products on wet grass. So, be sure to check the label.

Will Weed Killer Work on Wet Grass?

Only specific products work on wet grass. In general, those products include granular weed killers and natural remedies. Rain and water from your sprinkler system can wash chemicals away from the plants and onto your soil. And if that happens, your products won’t work.

DID YOU KNOW: A few formulas may require damp grass to help the chemicals stick to grass stalks.

Can I Apply Weed Killer After It Rains?

You can apply weed killer after the rain, but water could compromise the absorption. Plus, rain might transfer some of the chemicals to other locations, which could damage plants you want to protect. However, applying weed killer after the rain is much better than before it.

Should I Water My Lawn Before Spraying Weed Killer?

Try to spray your grass before applying weed killer. That way, you rinse the lawn to prepare plants for the product. Then, wait for about 48 hours before you water it again. Waiting gives the product time to soak into roots and kill weeds.

Also, be sure to mind your local watering laws. Some states don’t allow homeowners to water their lawns after a specific date. And if you do, the local government could subject you to fines or penalties.

FACT: California limits how much water citizens can use to maintain their lawns.

How Fast Do Weeds Grow Back?

Weeds can grow back fairly quickly. And even if you use artificial grass to increase your home’s value, the new owners will still have to kill weeds. Plus, heavy rains can wash away weed-killing products and grass seeds. So, try to protect your grass seedlings from the weather to prevent rapid regrowth.

Weeds generally take a few weeks to grow back, but that’s not always the case. Some species thrive where others barely survive. Meanwhile, the condition of your soil plays a role in how often you have to pull weeds. But some weed killers can help keep stubborn plants from returning.

So, use a mower with a dethatching attachment and remove twigs as often as possible. That way, your favorite plants get maximum sunshine and rainfall.

Why Are There Weeds in My Yard?

There are weeds in your yard because weeds flourish in diverse places. And if your lawn doesn’t have many other plants, rouge weeds can thrive.
