When stored under ideal conditions, grass seed lasts anywhere from 10 to 18 months from the testing date without any real decrease in the germination rate. You can still use the seeds after this timeframe, but the germination rates drop 10% to 20% each year. 

If you’re just embarking on an overseeding project, using seeds that have been in storage for a few years isn’t too big of a deal. However, if you’re planning on redoing your entire landscape, your best bet for a healthy, luscious lawn is to use new seeds.

If you spray a DIY vinegar solution that contains high salt, it can disrupt the soil's structure and make it difficult for plants to grow. That's why it's vital to avoid spraying vinegar solution on areas where you are trying to grow plants and flowers. When using a mix of vinegar and soap, some say you can plant a few days after the vinegar dries. 

If thrown on the ground and left, some Bermuda seeds will sprout on the surface, but you will have a diminished germination rate. It’s best to cultivate the area before spreading the seeds for optimal results. Rake the area first and then evenly distribute the Bermuda seeds. Cover the space with about ¼ inch of soil before watering the area.

Overseeding typically involves spreading grass seed either manually or with a machine that sprays the grass seed out and onto the soil. With overseeding, the grass seeds sit on the soil, and some may fall deeper into the soil if you aerated beforehand. With power seeding, a machine cuts narrow rows into the soil and pushes the grass seeds directly into the soil.
