Once you have purchased the seed, getting it started takes just a few easy steps. First, loosen the top quarter to half-inch of soil using a garden rake or similar tool. After the seed is planted, lightly pass a rake over the surface, blending the fertilizer and seed into the top quarter-inch of soil. Water the area thoroughly, but take care not to cause puddles, which would displace the seed. Now that your grass seed is off to the right start, the most important thing is to keep the soil moist.
Seed needs constant moisture to sprout and grow.
Plan to water the seeded areas several times a day for the first week after planting. During the second week, water once a day. Beginning in the third week, water only every two to three days, but more deeply. This will ensure that the roots get adequate water. Avoid walking on grass seedlings during the first few weeks of growth.
