Don’t wake up on the wrong side of your lawn this spring, opening your eyes to a crabgrass forest. If you’re worried about crabgrass, start paying attention to it now, so you won’t be scowling at it later. Certainly, crabgrass is ever-present in the lawn, especially during warmer months, but it’s always in a different stage. Rarely is the entire lawn full-grown crabgrass, because individual seeds are different in size, depth and germination time. As the weather gets warmer, crabgrass begins to emerge. According to researchers at the University of Maryland, the minimum daytime soil temperature for the first sighting of crabgrass is 54 degrees. Soil temperature has to be between 60-70 degrees for major crabgrass growth.
Harford County lawns can see 54-degree soil temperature as early as March. Short of taking painstaking temperature measurements, you can take the advice of Harford County lawn care services and watch for weeds to grow next to sidewalks, patios and driveways. Soil next to concrete gets warmer more quickly, and seeds often get lodged between the concrete edges. Once crabgrass begins to sprout here, you can be sure the rest of the lawn is not far behind. The earlier you apply a preventer or pre-emergent, the better chance you have of staying ahead of the crabgrass. However, the earlier you apply, the earlier it will wear off, so be aware that two or three applications might be required during the season.
Finally, if you have thin or bare patches in your lawn, be sure to seed it first so the new seeds can take hold. Crabgrass preventer has to be applied after seeding.
