4:00 AM - 8:00 AM
2-3 times per week
20-30 minutes per zone
Target depth: 1 inch total per week
Why 4:00 AM - 8:00 AM is Best for Murfreesboro, TN
Transition zone lawns face heat stress earlier in the day, so starting irrigation at 4 AM ensures water reaches roots before temperatures climb above 85 degrees. The slightly earlier window also helps warm-season grasses like bermuda and zoysia absorb moisture during their active metabolic period at dawn.
Time to Avoid
After 5:00 PM
Afternoon and evening watering in the transition zone wastes water to lingering heat evaporation and leaves grass wet during prime disease-development hours.

Watering by Grass Type
Tall Fescue
Tall Fescue has moderate drought tolerance due to its deep roots; water 1 to 1.5 inches per week, especially during summer heat.
Zoysia Grass
Zoysia is moderately drought-tolerant; water deeply once or twice per week, providing about 1 inch total.
Bermuda Grass
Bermuda grass is drought-tolerant but performs best with deep, infrequent watering of about 1 inch per week during active growth.
Kentucky Bluegrass
Kentucky Bluegrass needs consistent moisture -- about 1.5 inches per week. It will go dormant in drought but recovers well.
Drought Stress Warning Signs
Tall fescue leaves roll into tight tubes as the plant tries to minimize sun exposure and reduce evaporation from leaf surfaces.
The lawn develops an uneven appearance with some clumps wilting earlier than others because fescue is a bunch-type grass with varying root depths.
Leaf tips turn brown and crispy while the base of the blade may still be green, creating a scorched appearance across the lawn.
Growth slows dramatically or stops completely, and the grass fails to recover its normal height between mowing intervals.
The normally deep green color fades to a pale, grayish green that looks washed out compared to well-watered fescue lawns nearby.
