Normal Watering Window for Arlington, TX
Hot southern lawns lose significant moisture to evaporation once the sun is up, so the 4-8 AM window captures the coolest, calmest conditions of the day. Bermuda, zoysia, and St. Augustine grasses common in zone 8a are actively taking up water at dawn, making irrigation most efficient during this period.
Time to Avoid
11:00 AM - 4:00 PM
Midday watering in hot climates can lose 30-50% of applied water to evaporation and wind drift, wasting both water and money while failing to hydrate roots.
Normal Seasonal Schedule for Arlington, TX (Reference)
spring
- Frequency: 2-3 times per week
- Duration: 25-35 minutes per zone
- Depth: 1-1.5 inches total per week
- Notes: Warm-season grasses emerge from dormancy in spring. Begin irrigation as soon as you see green-up, usually when soil temperatures reach 65 degrees.
summerNow
- Frequency: 3-5 times per week
- Duration: 30-45 minutes per zone
- Depth: 1.5-2 inches total per week
- Notes: Peak growing season demands the most water. Split watering into two shorter sessions if you notice runoff before the full duration is complete.
fall
- Frequency: 2-3 times per week
- Duration: 20-30 minutes per zone
- Depth: 1 inch total per week
- Notes: Gradually reduce watering as bermuda and zoysia slow their growth. Overwatering in fall can promote fungal diseases as temperatures cool.
winter
- Frequency: Once every 2-3 weeks
- Duration: 15-20 minutes per zone
- Depth: 0.5 inches as needed
- Notes: Dormant warm-season lawns need very little water. Irrigate only during extended dry periods to keep roots and crowns alive.
Watering by Grass Type
Bermuda Grass
Bermuda grass is drought-tolerant but performs best with deep, infrequent watering of about 1 inch per week during active growth.
Zoysia Grass
Zoysia is moderately drought-tolerant; water deeply once or twice per week, providing about 1 inch total.
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.
Centipede Grass
Centipede grass prefers minimal watering -- about 1 inch per week. Overwatering encourages shallow roots and disease.
Drought Stress Warning Signs
Bermuda grass turns from bright green to a dusty blue-green, then straw-yellow as drought stress intensifies over several days.
Leaf blades become noticeably thinner and the canopy looks sparse as bermuda slows lateral stolon growth to conserve energy.
Internodes shorten dramatically and the grass stops sending out new runners, prioritizing root survival over canopy expansion.
Footprints persist for over an hour because drought-stressed bermuda loses the water pressure that normally keeps leaf tissue rigid.
Brown patches emerge along sidewalk edges and driveway borders first, where radiant heat from concrete accelerates soil drying.
