Fall Lawn Care: Overseeding, Fertilizing & Prepping for Spring

October is one of the best times to give your lawn the attention it deserves. Cooler temperatures, consistent rainfall, and reduced weed pressure create ideal conditions for grass to establish strong roots before winter. A few simple fall tasks—overseeding, fertilizing, and cleanup—can set the stage for a lush, green lawn next spring.

Why Fall Is the Perfect Season

Grass naturally slows its top growth in autumn and focuses energy on developing deeper roots. This means your efforts now—feeding, seeding, and clearing debris—help strengthen the root system that supports healthy growth when warmer weather returns.

Overseeding for a Thicker Lawn

Bare patches or thinning areas? Fall overseeding is your best fix. Start by mowing your lawn shorter than usual and raking to remove thatch and debris. Spread a high-quality grass seed blend suited to your conditions, then lightly rake or roll to ensure good seed-to-soil contact. Keep the soil consistently moist for the next few weeks to help new grass establish before winter dormancy.

Fertilizing to Build Strength

Fall fertilization is like giving your lawn a hearty meal before its winter nap. Choose a slow-release or winterizing fertilizer high in potassium to boost root development and improve cold tolerance. Apply it after overseeding but before the ground freezes, ideally in late September through October.

Prepping for Spring Success

Clearing leaves, adjusting mowing height, and edging beds all help prepare your lawn for the months ahead. As the season winds down, keep mowing until grass stops actively growing—usually when temperatures stay below 50°F. Leaving grass too long can lead to matting and disease.

FAQs

Q: Can I seed and fertilize at the same time?
A: Yes, as long as you use a starter fertilizer designed for new seed. Avoid products containing weed control, which can prevent seed germination.

Q: How often should I water after overseeding?
A: Lightly water once or twice a day until seedlings are established, then reduce frequency as roots develop.

Q: What’s the best mowing height in fall?
A: Keep grass about 2½ to 3 inches tall. This height helps retain moisture and protects roots from frost damage.

Q: Do I need to aerate before seeding?
A: Aerating is highly recommended. It loosens compacted soil and creates ideal conditions for seed-to-soil contact and root growth.
