Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you.
Preventing clover from growing and spreading comes down to maintaining a healthy lawn by following a lawn maintenance schedule. Proper fertilization and a healthy turf will help your lawn fight of encroaching clover infestations season after season.
Follow a Proper Fertilization Schedule
The best long-term defense against clover infestations is sufficient, proper fertilization, since clover takes hold in areas with low nitrogen in the soil. Making sure you are following a fertilization schedule will help to regulate the proper amount of nitrogen in your soil.
This will reduce the amount of clover in your yard every year, and in the long term, will help to prevent clover from growing in your yard. Fall nitrogen applications are especially helpful in preventing more clover the following year.
Keeping your lawn as healthy as possible will allow your turf to grow thick and vigorous, which will help your lawn edge out clover and other weeds from encroaching into your grass.
Proper drainage, good mowing practices, and irrigation are all extremely important to maintain throughout the year. The healthier your lawn, the less likely clover will take hold in your lawn.
Apply A Pre-Emergent
Pre-emergent herbicide applications in the spring will help to prevent clover from taking over your lawn. Timing of pre-emergent products is very important; they should be applied when the soil temperatures reach 55 degrees, which is when clover begins to germinate. This timing can vary depending on where you live, but is usually April-May. Contact your local extension office for more help with pre-emergent application timing.
