Mother Nature has been teasing us with some beautiful spring like weather for a month or so now here in the Lakes Region of New Hampshire and here’s hoping we are headed in the right direction. With the warmer temperatures and lack of snow it’s a great time to think about what we can do to get the lush green lawns we’ve been dreaming about and there’s no room in the dream for crabgrass! Crabgrass control starts with good practices that encourage the growth and health of desirable lawn grasses, as crabgrass will not invade vigorous, healthy turf. Good management is the best means of crabgrass control, and often least expensive as it will also help control other weeds and diseases.
One of the first things on the list for a healthy lawn is an application of a pre-emergent weed control just after completing a spring clean up. If your lawn tends to be spotted with yellow dandelions and crabgrass, pre-emergent weed prevention is for you. Timing is everything however; so don’t get ahead of yourself before your lawn is ready. Pre-emergent crabgrass preventer can wear off before crabgrass actually germinates if you put it down too early. Crabgrass germinates based on soil temperatures, generally around 56 to 64 degrees at the earliest.
Many professionals watch for a colorful sign in the landscape as an indicator that soil temperatures are within an adequate range for crabgrass to germinate. The sunny golden yellow of forsythia in bloom is a sure sign to move forward with your pre-emergent crabgrass control application, as they will be in full bloom just prior to crabgrass germination. Keep in mind that the herbicide will not be effective after the crabgrass is out of the ground and actively growing so keep this window in mind.
Applied in spring along with your much needed spring fertilizer, pre-emergents work by stopping weeds and crabgrass before the plants have an opportunity to germinate and grow. They work by forming a barrier over the surface where they are applied leaving the roots of established plants (such as perennials, shrubs and trees) unaffected. Be sure to keep pre-emergents away from garden beds where you may be planting seeds. You need to activate the herbicide by watering the lawn after the application. Most products call for a half-inch of irrigation (or rain) within 21 days of application.
Your lawn will grown green and healthy if it doesn’t have to compete with weeds for sunlight, water and nutrients. Apply a pre-emergent yourself or leave your weeds in the experienced hands of the “Lawn Enforcement Officers” at Miracle Farms.
