During fall and winter, it’s not uncommon for a significant portion of your existing grass to die off, so refreshing your lawn with new seed will offset any losses. Skipping this step will result in a thin, unhealthy looking lawn, even during the height of the growing season. If you choose to aerate your lawn with Blades of Green, you’ll also receive a new batch of seed to provide your lawn with a jolt of fresh growth. This way, you can replace any dead grass blades and increase your lawn’s fullness come springtime.
