Pulling out weeds by hand can be an uphill task, so spraying herbicides is an effective way to get rid of weeds from your lawn.
Herbicides help kill even the most persistent weeds, but they take time to show the desired results. And lawn mowing at the wrong time can jeopardize the weed-killing process.
So, if you’re wondering - “how soon after spraying weeds can I mow?” read on to know the answer!
How Long Will It Take Weeds To Die After Spraying?
Usually, any good herbicide takes around two to four weeks to kill the weeds in your lawn. Systemic herbicides are known to be the most effective, and it takes about two weeks to get rid of all the weeds in your backyard using these herbicides. So, you might need to wait for a few weeks to see noticeable results.
But, you can easily hasten the process by cutting down the weeds first and then spraying the herbicides to get quicker results. Plus, spraying herbicides on dry and hot days usually shows better results.
Once you’ve controlled the growth of weeds in the garden, only then can you think of lawn maintenance and mowing. And as it is a chemical process, it takes some time for the weeds to absorb the herbicides. So, it is best to wait a while before you start mowing the lawn.
When To Begin Lawn Mowing?
Any concentrated liquid herbicide takes some time to dry and travel to the roots of the weeds from their leaves to kill them from the inside. Hence, mowing the lawn immediately after spraying herbicides will shorten the surface area of the weeds.
This will reduce the amount of absorption, and less herbicide will get to penetrate the roots, which will render the entire weed-killing process ineffective. So, while this may sound difficult, you have to wait it out. I suggest holding off watering and mowing your lawn and giving time to the herbicides to penetrate the roots of the weeds.
Once the herbicides travel to the roots, the weeds will die more quickly, and their chances of regrowth will reduce significantly. Hence, I think it’s best to wait for 24 or 48 hours before you start mowing your lawn.
If the weeds start growing again after some days, let their leaves grow a little before spraying herbicides and avoid mowing for a few days.
Final Thoughts
Even though mowing is essential for lawn maintenance, you have to pick the right time to mow your lawn. Mowing the garden immediately after spraying weed killers can do more harm than good.
I’ll suggest you give time to the herbicides to act on the weeds before you mow them down. And in the meantime, keep your children and pets away from the lawn to avoid any serious health hazards.
