Transition Zone Lawn Care

The transition zone (roughly zones 6-7, spanning the Mid-Atlantic, Upper South, and parts of the Midwest) is where lawn care is hardest. Summers are too hot for cool-season grasses; winters are too cold for warm-season grasses.

Choosing Your Grass

In the transition zone, you have two viable strategies:

• Cool-season (TTTF or KBG/TTTF blend): Green year-round but struggles in July-August heat. Requires overseeding every fall. Best for zones 6a-6b.
• Warm-season (zoysia): Thrives in summer, goes dormant (brown) in winter for 4-5 months. Most cold-hardy warm-season option. Best for zones 7a-7b.

Summer Stress Management

Cool-season lawns in the transition zone face a critical period from mid-June through August. Raise mowing height to 4+ inches, stop fertilizer applications when air exceeds 85°F, and water deeply to sustain roots.

Fall Recovery

Fall is the most important season for transition zone cool-season lawns. Aerate, overseed, and apply fall fertilizer when soil temperatures drop to 55-70°F. This is when your lawn recovers from summer stress and builds density for next year.
