Contractors restore lawns disturbed during the project with hydro-seed mulch or grass seed. You'll need to maintain the new lawn on your property as you did before the construction. Proper watering, mowing and weed control will help you establish your the new lawn. Keep in mind that the contractor will return if the lawn needs more seeding or other restoration steps.
Mowing the new lawn
Mow the new lawn when the grass reaches 1 to 1.5 inches in height. This should take about 3 to 4 weeks after the seeding. After establishing the lawn, maintain a 2.5 inch mowing height.
Fertilization
The contractor applied starter fertilizer with the hydromulch. Make sure to apply fertilizer after about 4 to 5 weeks. We recommend a fertilizer blend of Nitrogen (N), Phosphorus (P) and Potassium (K). Common examples are 12-12-12 (N-P-K) or 20-10-10 (N-P-K).
Weed Control
Make sure to keep your grass at about 2 to 2.5 inches in height. This will kill off many weeds. Other weeds like dandelions should be sprayed in the fall, if your lawn has been cut around 7 to 8 times. Crabgrass will die out after the first frost in the fall. You can also treat your lawn with a pre-emergent crabgrass control in the following spring to stop the germination of new crabgrass.
