As winter fades and warmer temperatures arrive, March marks the true beginning of the landscaping season in Texas—especially here in Houston. This is the month when your lawn and garden “wake up,” and the work you do now will directly impact how your landscape performs through the intense summer ahead.

At Strong Landscaping, we believe a proactive, seasonal approach is the key to a vibrant, healthy outdoor space. Here’s your expert guide to March landscaping tasks in Texas.

Why March Is So Important for Texas Landscapes

March is often considered the spring kickoff for lawn care and planting. As soil temperatures rise and daylight increases, turfgrass begins actively growing again, and plants enter a critical growth phase.

Skipping essential maintenance now can lead to weeds, pests, and weak root systems later in the season.

1. Plant Cool-Season Flowers & Vegetables

March is the perfect time to refresh your beds with cool-season annuals and early vegetables.

• Plant seasonal color like petunias, snapdragons, and pansies
• Start vegetable gardens with lettuce, spinach, and herbs
• Prepare beds by loosening soil and removing winter debris

This early planting window ensures your landscape is full of color and productivity before summer heat sets in.

2. Fertilize Your Lawn for Spring Growth

Your lawn is coming out of dormancy and needs nutrients to thrive.

• Apply a slow-release fertilizer to encourage steady growth
• Avoid over-fertilizing too early to prevent feeding weeds
• Focus on building strong roots, not just green blades

A properly timed feeding in March helps lawns stay thick, green, and resilient throughout the year.

3. Start a Smart Watering Routine

As temperatures rise, your irrigation habits should adjust accordingly.

• Begin consistent watering schedules
• Water deeply but less frequently to promote deep roots
• Check soil moisture before watering to avoid overwatering

Proper irrigation now prevents stress during Houston’s hot summer months.

4. Watch for Early Pest Activity

March is when many common Texas lawn pests begin to emerge.

• Inspect for fire ants, grubs, and early insect activity
• Treat issues early before infestations spread
• Monitor plant leaves for damage or discoloration

Early detection is key—addressing pests now prevents costly damage later.

5. Clean Up & Prepare Landscape Beds

Spring prep is essential for healthy plant growth and curb appeal.

• Remove leaves, weeds, and winter debris
• Loosen compacted soil to improve airflow and drainage
• Add fresh mulch to retain moisture and suppress weeds

A clean, well-prepared bed creates the ideal foundation for new plantings and seasonal color.

6. Inspect Your Irrigation System

Before Houston heat arrives, make sure your system is working properly.

• Check for leaks, broken heads, or misaligned sprinklers
• Ensure proper coverage (not sidewalks or driveways)
• Adjust settings for seasonal watering needs

An efficient irrigation system saves water and protects your investment in your landscape.

7. Consider Aeration for Healthier Soil

If your lawn suffers from compacted soil, early spring is a great time to act.

• Core aeration improves air, water, and nutrient flow
• Encourages deeper, stronger root systems
• Especially beneficial for high-traffic lawns

Aeration in March or early April can significantly improve lawn performance throughout the year.

Set Your Landscape Up for the Rest of the Year

March is more than just a transition month—it’s your opportunity to get ahead of the season. From fertilization and planting to irrigation and pest control, every step you take now contributes to a healthier, more beautiful landscape.

A well-maintained Texas landscape doesn’t happen by accident—it’s the result of timing, expertise, and consistent care.
