The snow is gone and now is the time to start thinking about the most important step in keeping your lawn free of weeds: the pre-emergent application. Pre-emergent is a product that prevents weeds from starting, mainly crabgrass, spurge and oxalis. But why so early? Along the Wasatch Front crabgrass germinates from mid-April to late May, so you must treat the lawn before this. March and April are the only times to do this, with the pre-emergent lasting the whole growing season. However, once a seed has started, it is too late to apply it. Spring also provides us with cool temperatures and ample water by rain and dew, which allows the pre-emergent to work faster.
Although a good weed killer can knock down some of the most common weeds that pop up in your lawn, few will be able to keep aggressive weeds like crabgrass, spurge and oxalis from taking over the lawn. Pre-emergent will give you a head start on the season and will make it much easier to control the various weeds. In many instances, when the pre-emergent application is applied at the proper time, those aggressive weeds will never get the chance to take over your lawn.
If there’s one thing you can do to your lawn this spring it should be the pre-emergent application. So what are you waiting for?
