Lawn Care Schedule for Johnson City, Tennessee
Zone 7b has short, mild winters with only occasional hard frost and a nearly 9-month growing season beginning in late February. Warm-season grasses are fully viable here, and tall fescue lawns require careful summer management to carry them through the extended heat.
Tennessee's transition zone status makes tall fescue the dominant grass choice for its heat tolerance, while Bermuda thrives in the warmer western half of the state nearer Memphis.

Treatment Guides for the Transition Belt
Fertilization
Feed your lawn at the right time — not on the bag's schedule.
Pre-Emergent
Stop crabgrass before it starts — timing is everything.
Post-Emergent
Kill the weeds that are already there — selectively and safely.
Overseeding
Thicken thin turf and fill bare spots during the optimal seeding window.
Aeration
Break up compaction and open the soil to water, air, and nutrients.
Watering
Water deep and infrequent — not shallow and daily.
Mowing
The one-third rule changes everything about how your lawn looks.
Fungicide
Prevent disease before it spreads — fungicide rarely rescues an infected lawn.
