Step 7: Pick seed to match your site
Step 8: Prepare the seed
To avoid applying too much seed, pour the seed and fertilizer/bulking agent (Milorganite is one brand), in a 4:1 ratio, in a plastic bucket and mix it thoroughly.
When to Plant
There are good and bad times of year for starting a project like this. In cold climates, plant new grass seed in early spring as the lawns are just coming out of winter (early to mid-April) or late summer from about mid-August to mid-September. In warm-weather climates, plant in late spring/early summer. if you're not sure, your local extension service to get planting advice from a turf expert.
Step 9: Spread the seed
Load the seed into a spreader and apply it. Make sure it doesn't fly into nearby gardens. Turn the broom rake upside down and drag it side-to-side over the furrows until only 10 to 15 percent of the seed remains uncovered. To get good seed-to-soil , compact the soil with a rented sod roller filled halfway with water.
