Rake
Lawn care success in the Spring will begin with removing any debris that was not collected in late Fall. Loosen up any matted grass caused by snow mold which slows down any new growth this season.

Use a spring-tine rake or a thatcher to removal excess dead grass/ thatch.
Aerate
We understand that Fall is the best time for cool-season types. But if you didn’t get to it last fall you can aerate in early spring. Aerating will remove cores of thatch!
Dethatch
Spring is the best time to dethatch your lawn. Use a spring-tine rake or a thatcher to removal excess dead grass/ thatch. Removing dead grass on your lawn and the heavy thatch layer will allow for a greener look and a healthier lawn. When you do not remove thatch and you fertilize the nutrients applied do not have a chance to do there job due to the heavy thatch issue. Aim for early spring for cool-season grasses.
Weed
Lawn care success in the spring is all about timing of when you apply your pre emergent to prevent germination of broadleaf weeds. Most product bags have application timing advice but the first pre emergent application should be in early Spring around March 1st – March 15th.

Fertilize
Apply spring fertilizer roughly three – four weeks after grass starts greening (that usually corresponds to the time following two or three mowings).
Mow
Start mowing when the ground is dry enough and grass is long enough to require cutting. Cut at the proper height for your type of grass, organic practice is 3 – 4 inches. Do not cut more than 1/3 of the grass blade per mowing.
