Lawn Care Considerations in Baltimore

The transition zone is the hardest US lawn climate — too hot for pure cool-season grasses, too cold for full warm-season recovery. Brown patch fungus is common in tall fescue lawns through humid July and August. Grub pressure peaks in late summer. Several states including Virginia and Maryland restrict phosphorus fertilizer. Tall fescue is the most reliable choice because it tolerates both summer heat and winter cold without going fully dormant.

Mow frequency

Once a week from March through November. Tall fescue may need two cuts per week during peak spring and fall growth flushes.

Mow height

Tall fescue: 3 to 4 inches. Kentucky bluegrass: 2.5 to 3.5 inches. Bermuda: 1 to 2 inches. Zoysia: 1.5 to 2.5 inches.

Water needs

1 to 1.5 inches per week during active growth. Deep, infrequent watering preferred. Cool-season grasses need extra water during summer heat to avoid dormancy.

Irrigation

Strongly recommended for consistent appearance during humid summer stress periods. Many transition-zone lawns survive without it but show summer stress.
