When to Fertilize Your Houston Lawn: A Complete Guide

Fertilizing your Houston lawn at the right time is crucial for maintaining a lush, healthy landscape. Our comprehensive guide covers the complete fertilization schedule for the Houston area, taking into account our unique climate and growing conditions.

Understanding Houston's Growing Seasons

Houston has a unique climate that allows for lawn growth during extended periods. Unlike northern states, our warm winters mean your lawn may be actively growing year-round, especially St. Augustine grass varieties popular in the area.

Spring Fertilization (March-April)

Spring is an excellent time to apply fertilizer as your grass emerges from dormancy. Apply a balanced fertilizer (approximately 16-4-8 ratio) to promote healthy green growth. This is particularly important after our unpredictable spring weather.

Summer Maintenance (May-August)

During Houston's hot summers, lawn growth slows significantly, and your grass focuses on survival rather than expansion. Use a slow-release fertilizer with higher potassium content to help your lawn withstand heat stress. Apply every 6-8 weeks during this period.

Fall Fertilization (September-October)

Fall is another critical time for fertilization. As temperatures cool, your grass experiences a growth surge. Apply a quality fertilizer in early September to capitalize on this growth period. A second application in October can strengthen your lawn heading into winter.

Winter Considerations (November-February)

Many Houston lawns remain green throughout winter, especially St. Augustine varieties. A light application in December can maintain color, but avoid heavy nitrogen applications that might encourage tender new growth vulnerable to occasional freezes.

Choosing the Right Fertilizer

Select fertilizers specifically formulated for Texas grasses. Products containing:

• Slow-release nitrogen for steady growth
• Adequate phosphorus for root development
• Potassium for stress tolerance
• Micronutrients like iron for color enhancement

Application Tips

Always follow label instructions carefully. Water your lawn after application to activate the fertilizer. Never apply during extreme heat or drought conditions. If you're uncertain about your soil's nutrient levels, consider a soil test from your local extension office.

Professional lawn care services can optimize your fertilization schedule based on your specific soil conditions and grass type.
