August on Martha’s Vineyard is hot, dry, and tough on turf. Higher mowing, pre-dawn deep watering, low-nitrogen organics, and early-fall renovation keep cool-season grass alive and lush. Join Estate Care’s Year-Round Lawn Program and let our team handle every step—stress-free.
Why August Matters on Martha’s Vineyard
Average daytime highs run 79 °F, slipping to 76 °F by month-end, while rainfall is hit-or-miss—perfect conditions for heat stress and crabgrass. weatherspark.com Homeowners who wait until September to act often face bare patches and pricey reseeding.
6 Heat-Smart Tactics
| # | Action |
| 1. Raise the Blade (3½ – 4 in.) | Taller grass shades soil, lowering surface temps and reducing crabgrass germination by up to 50 %. Our professional mowing crew sharpens blades weekly for a perfectly clean cut. |
| 2. Deep, Dawn-Only Watering | One ¾-inch soak before 9 a.m. on your designated watering day (Island Level-1 rule: once per week, before 9 a.m. or after 5 p.m.) meets MassDEP limits and trains deep roots. Mass.gov Smart controllers let us shift schedules the moment towns tighten rules. |
| 3. Pause Heavy Nitrogen | Cool-season grass slows at > 85 °F. Quick-release N feeds disease. Instead, we spoon-feed kelp and compost teas that boost stress tolerance without forcing soft growth. ag.umass.edu |
| 4. Target Warm-Weather Weeds & Pests | Thick, higher-cut turf plus spot organic controls starve crabgrass, chinch bugs, and gray leaf spot of ideal habitat—saving you costly curatives later. |
| 5. Relieve Compaction & Shade Stress | Foot traffic + baked clay compact soil. We schedule core aeration in late August, prune low limbs for airflow, and mulch beds to stabilize soil temps. |
| 6. Book Your Fall Revival Now | Soil tests, seed orders, and slit-seeding dates fill fast. Annual-program clients get priority for September overseeding and guaranteed slots for every step. |
Local Case Study
Last August an Edgartown client’s rye/fescue mix browned to the crowns. We raised mowing height, switched to pre-dawn deep watering, and applied a kelp tonic. Within two weeks color returned; our September slit-seeding yielded a seven-inch root zone by the following May.

FAQ
Q1: What’s the best time to water my lawn in August?
Before sunrise, between 5 a.m. and 8 a.m., to reduce evaporation and meet town watering bans.
Q2: Should I fertilize during a heatwave?
Skip high-nitrogen granules; use light organic tonics or wait until soil temps drop below 70 °F.
Q3: How high should I mow?
Set blades to at least 3½ in. Higher cuts shade soil and discourage crabgrass.
Q4: When should I aerate?
Late August/early September—just before overseeding—for maximum seed-to-soil contact.
