Common garden weeds, like other plants, experience their greatest period of growth during the spring and into the summer.That implies that between the months of May and June is the ideal time to apply weed killer to the weeds that are growing on your lawn.If you are able to schedule a weedkiller treatment for the month of May, you will allow yourself plenty of time to monitor the lawn after the treatment to ensure that all of the weeds have been eliminated.
In order to achieve the greatest results, gardeners should time the application of weed killer such that it occurs before the weed seeds begin to germinate, which often occurs in the early spring.When dealing with particularly aggressive weeds like crabgrass, gardeners frequently repeat the weed killer around eight weeks after the initial spraying.This helps to keep the weeds under control.
