Lawn Care Basics for Southeast Texas: Seasonal Landscaping Tips

Southeast Texas is a unique environment for lawn care. Our long growing season, heavy rainfall, intense summer heat, and humid nights create conditions that don't follow the same rules as the rest of the country. If you've moved here from up north, you've probably noticed that your lawn behaves differently—and that the calendar that worked in Ohio or Michigan doesn't work here. At Eman's Pressure Washing & Landscaping, we maintain lawns across Friendswood, Alvin, Santa Fe, and the entire Bay Area. Here's our seasonal guide to keeping your lawn healthy and your beds looking sharp.

Understanding Southeast Texas Grass Types

Most lawns in our area are one of three types:

• ▸St. Augustine — The most common in the Bay Area. Broad, flat blades; loves our heat and humidity; goes dormant (brown) in winter. Needs 1–1.5 inches of water per week.
• ▸Bermuda — Drought-tolerant and sun-loving. Fine blades; common in newer subdivisions and sports fields. Goes dormant in winter and shade.
• ▸Zoysia — A newer option that's gaining popularity. Dense, soft, and more shade-tolerant than Bermuda. Slower growing, so less mowing.

All three are warm-season grasses that green up in April–May and go dormant in November–December. Your care schedule should follow this cycle.

Spring (March–May): Wake-Up and Growth

As temperatures rise and your grass starts to green up:

• ▸First mow — Cut at the recommended height for your grass type (St. Augustine: 3–4 inches, Bermuda: 1–2 inches, Zoysia: 1.5–2.5 inches). Never remove more than 1/3 of the blade height in a single mowing.
• ▸Pre-emergent — Apply a pre-emergent herbicide in early March to prevent summer weeds like crabgrass before they germinate.
• ▸Fertilize — Apply a slow-release nitrogen fertilizer once the grass is fully green (usually mid-April).
• ▸Clean beds — Refresh mulch in flower beds (2–3 inches deep) to suppress weeds and retain moisture.

Summer (June–September): Survival Mode

Summer in Southeast Texas is about keeping the lawn alive, not making it thrive:

• ▸Watering — Water deeply (1–1.5 inches per week) in the early morning (5–9 AM) to minimize evaporation. Avoid evening watering, which promotes fungus.
• ▸Mowing — Raise your mowing height by 0.5–1 inch in July and August to help the grass cope with heat stress. Taller grass = deeper roots = more drought tolerance.
• ▸Skip the fertilizer — Fertilizing during peak summer heat can burn the grass. Wait until fall.
• ▸Watch for fungus — Our humid nights are perfect for brown patch and gray leaf spot. If you see circular brown patches, call a professional—fungus spreads fast.

Fall (October–November): Recovery and Prep

As temperatures drop, your lawn enters its most important recovery period:

• ▸Fall fertilizer — Apply a winterizer fertilizer in October to strengthen roots before dormancy. This is the most important fertilization of the year.
• ▸Leaf management — Don't let leaves sit on the grass for more than a few days; they block sunlight and trap moisture, promoting fungus.
• ▸Last mow — Give the lawn a final cut at the normal height before it goes dormant.
• ▸Bed cleanup — Cut back perennials, remove annuals, and add a fresh layer of mulch for winter weed suppression.

Winter (December–February): Dormancy

Your lawn is brown and dormant, but there's still work to do:

• ▸Watering — Only if we have an unusually dry winter. Dormant grass needs very little water.
• ▸Weed control — Apply a post-emergent for winter weeds (henbit, chickweed, dandelion) that pop up in the dormant lawn.
• ▸Tree and shrub pruning — January is the ideal time to prune deciduous trees and shrubs while they're dormant.
• ▸Planning — Winter is the time to plan bed redesigns, new plantings, and hardscape projects for spring.
