Cold and frozen ground sounds unsuitable for doing any form of seeding, however, it may surprise you to know that you can plant grass seed in winter. It can be done via dormant seeding, which is effective under the right conditions and will help you to get ahead come spring.
Dormant seeding requires good timing and patience. It is no winter miracle cure with instant results, but it can be a useful way to get a head start on spring lawn care to cover thin or bare patches of grass.
