Top 7 Lawn Care Mistakes to Avoid This May

May Is Make-or-Break Month for Lawns in Steiner Ranch

As temperatures rise and spring growth accelerates, May becomes a crucial month for setting your lawn up for a lush, green summer. But even with the best intentions, many Steiner Ranch homeowners make lawn mistakes during this time that can lead to stunted growth, brown patches, or wasted effort.

Avoiding these common missteps now can save you time, money, and frustration later.

Overwatering Your Lawn

Why It’s a Mistake:
Many homeowners water their lawns too often in May, thinking it will encourage growth. In reality, shallow, frequent watering trains grass roots to stay near the surface—making them more vulnerable during hot Texas summers.

What to Do Instead:
Water deeply and infrequently. Aim for 1 inch of water per week, early in the morning. This encourages deep root systems that withstand drought.

💡 Pro Tip: Use a tuna can to measure 1 inch of water from sprinklers.

Cutting Grass Too Short

Why It’s a Mistake:
“Scalping” your grass leaves it vulnerable to heat stress and weeds. It also removes too much of the blade, which reduces the plant’s ability to photosynthesize.

What to Do Instead:
Follow the “one-third rule”: never cut more than one-third of the grass blade at a time. Adjust mower height depending on your grass type:

  • Bermuda: 1.5–2 inches
  • Zoysia: 2–2.5 inches
  • St. Augustine: 2.5–4 inches

✂️ Regular mowing (once per week) keeps growth healthy and controlled.

Fertilizing at the Wrong Time

Why It’s a Mistake:
Applying fertilizer too early in the spring or too late in May can lead to excessive top growth with weak roots, or even burn the grass.

What to Do Instead:
May is a great time to fertilize if your lawn is fully green and growing. Choose a slow-release, nitrogen-rich fertilizer designed for your specific grass type.

Ignoring Soil Compaction

Why It’s a Mistake:
After winter and early spring rains, soil can become compacted—especially in high-traffic areas. Compacted soil limits air and water flow to the roots.

What to Do Instead:
May is a great time to schedule lawn aeration to break up compacted soil, promote root growth, and improve fertilizer uptake.

Signs of compaction:

  • Thin or patchy grass
  • Water pooling after rainfall
  • Soil that feels hard or resists digging

Letting Weeds Take Over

Why It’s a Mistake:
Many homeowners wait too long to address spring weeds like crabgrass, dandelions, and clover. By May, these weeds are already spreading aggressively.

What to Do Instead:

  • Use a post-emergent herbicide to tackle visible weeds
  • Apply pre-emergents earlier next year (February–March)
  • Keep your lawn dense and healthy to naturally crowd weeds out

🌼 Weeds compete with your grass for water, sunlight, and nutrients—don’t let them win!

Skipping Routine Lawn Inspections

Why It’s a Mistake:
Many lawn issues—like fungus, pests, or irrigation leaks—start small. By the time you notice a brown patch, it may already be too late.

What to Do Instead:
Do a weekly walk-through of your lawn. Look for:

  • Discoloration
  • Mushrooms or mold
  • Insect activity
  • Standing water

🎯 Catching these issues early can save you hundreds in repairs or reseeding.

Using Dull Mower Blades

Why It’s a Mistake:
Dull blades tear rather than cut grass. This creates ragged edges that turn brown, increase water loss, and make your lawn vulnerable to disease.

What to Do Instead:
Sharpen your mower blades every 20–25 hours of use or at least once per season.

🔧 Sharp blades = clean cuts = healthier grass.

Why May Is the Ideal Month to Fix Lawn Mistakes

By catching and correcting these lawn mistakes in May, you give your yard time to:

  • Recover before summer heat sets in
  • Grow deeper roots for drought resistance
  • Fill in bare patches naturally
  • Build strong defenses against weeds and pests

It’s much easier (and cheaper) to prevent problems now than to fix them later in the season.
