Every lawn contains seeds of a virtual weed army. The wind carries seeds from other places, seeds are carried on shoe soles and are dropped by birds and other animals. For effective lawn weed control, it’s important to plan both a good defense and offense. In a nutshell, this means combining both good cultural and weed prevention practices with properly timed treatments.
The best method of weed prevention is always a properly mowed and healthy stand of grass. Mowed high, your turf shades the soil, keeping sun and heat from reaching the weed seeds. Thick turf also helps with weed control by denying weeds the resources (water and sunshine) they need to gain a foothold.
Most broadleaf weed controls are systemic. This means they have to be absorbed into the weed and moved through the leaves and into the roots. This is called translocation.
Depending on the type of weed and how actively it’s growing, this can happen in a few hours or may take several days. Once fully absorbed, weed control systems actually cause the cells of the weed to grow so fast they burst. That’s why weeds curl into strange shapes after a lawn treatment. Remember that broadleaf weed controls can only work on weeds that are present and actively growing at the time of a treatment. Because new weeds blow in and sprout, regular lawn weed control treatments are required
What to Do and What to Expect
Due to the delay in weed control while the herbicide is being absorbed, mowing and watering should be avoided immediately after a lawn treatment. Wait at least 2 hours before watering and 24 hours before mowing after weed control applications. These practices will actually speed up the level of weed control.
