Bare Spots / New Grass: Remove debris, then rake the soil to loosen and smooth the top layer. Overseeding: Same instructions as above but start by mowing existing grass as short as possible.
Spread the seed evenly using a drop, rotary or hand-held spreader according to the settings below. Lay down a starter fertilizer to help the seedlings grow healthy and strong. Rake gently to work your seed & fertilizer into the soil.
The most important step! Keep the soil moist! Water daily (twice a day if you have to) until grass sprouts and reaches about 3" tall.
Additional Care Tips
Once your grass is 1/3 taller than the recommended mowing height you may being mowing it. Avoid removing more than 1/3 of the total grass blade length at any single mowing to keep your grass thick and healthy. Increase your mowing height in the summer months to reduce grass stress.
