Application. The proper time to apply weed and feed to your grass is after you are able to mow the grass at least four times. In general, the first mowing of new grass takes place two to three weeks after planting and proceeds every week to two weeks after that.f you decide to apply weed and feed, do so three to four days after mowing and always on a wet lawn when you can ensure it will not rain or be watered for two days afterward. Follow all manufacturer's instructions and warnings for the product.
After you seed, wait until you've mowed the new grass at least four times, which could be six to eight weeks after seeding, before adding herbicides.This keeps the chemicals from stunting the seedling's growth.f you used a crabgrass preventer, that time frame might extend to four months. Check the herbicide manufacturer's label to confirm how long you must wait, as it can differ between herbicide products. The pre-emergent herbicides stop weed seeds from germinating, but they can stop grass seeds as well.
