The Low-Tech Times

Although you can lay down grass seed anytime of the year, early spring or fall are the best time to do the job.

Many people hire companies to reseed their lawn.  Others buy or rent expensive equipment to aerate their lawn prior to putting down seed.

Instead of using expensive motorized aeration machines, The Low-Tech Times recommends using a garden weasel to prepare the soil for seed.  This is especially recommended if you are only reseeding bare patches or do not have a very large area to reseed.  Once the soil is prepared with a garden weasel, simply lay down the grass seed, cover with straw, and keep moist.

You should research what type of grass does best in your area; I have found that tall fescue works well here in Virginia.
