Best Fertilizer Schedule for Texas Lawns

A healthy, green lawn doesn't happen by accident. Proper fertilization is one of the most important factors in maintaining thick, healthy grass that can withstand the heat, drought, and weed pressure common throughout Texas.


One of the biggest mistakes homeowners make is applying fertilizer at the wrong time of year. Too much fertilizer, too little fertilizer, or poor timing can all lead to disappointing results.


If you have Bermuda grass, which is the most common lawn type in San Angelo, this guide will help you understand the best fertilizer schedule for keeping your lawn healthy year-round.

Why Fertilizing Matters

Grass requires nutrients to grow, recover from stress, and maintain its green color. The three primary nutrients found in lawn fertilizers are:

  • Nitrogen (N) – promotes green growth
  • Phosphorus (P) – supports root development
  • Potassium (K) – improves drought and stress tolerance


When applied correctly, fertilizer helps create a lawn that is:

  • Thicker and greener
  • More drought resistant
  • Better able to crowd out weeds
  • More resilient to heat and foot traffic

Early Spring (March–April)

As temperatures begin warming and Bermuda grass starts coming out of dormancy, homeowners become eager to fertilize.


However, timing is important.


What to Do

  • Wait until the lawn is actively growing and at least 50% green.
  • Apply a balanced fertilizer or one designed specifically for Bermuda grass.


Why It Matters

Applying fertilizer too early can encourage weak growth and may waste nutrients while the grass is still dormant.

Late Spring (May)

This is often the most important fertilizer application of the year.


What to Do

  • Apply a nitrogen-rich fertilizer.
  • Water thoroughly after application.


Benefits

  • Encourages dense turf growth.
  • Helps the lawn fill in thin areas.
  • Increases resistance to weeds.

Early Summer (June)

As temperatures rise, Bermuda grass enters its peak growing season.


What to Do

  • Apply a second fertilizer application if needed.
  • Follow label directions carefully.


Benefits

  • Maintains strong growth.
  • Supports healthy color throughout summer

Mid-Summer (July–August)

Texas summers can be extremely stressful on lawns.


What to Do

  • Apply fertilizer only if the lawn is healthy and actively growing.
  • Avoid excessive nitrogen during periods of extreme heat.


Benefits

  • Helps maintain color and vigor.
  • Supports recovery from drought stress.


Important Tip

Never fertilize a lawn that is severely drought-stressed without correcting irrigation issues first

Early Fall (September)

Fall fertilization helps prepare lawns for cooler weather.


What to Do

  • Apply a fertilizer containing potassium.
  • Continue normal mowing practices.


Benefits

  • Strengthens roots.
  • Improves winter hardiness.
  • Supports recovery from summer stress.

Winter (October–February)

Bermuda grass enters dormancy during colder months.


What to Do


Benefits

  • Prevents unnecessary growth.
  • Helps prepare the lawn for spring green-up.

Common Fertilizer Mistakes

Many lawn problems can be traced back to improper fertilization.


Avoid these common mistakes:


Fertilizing Too Early

Applying fertilizer before Bermuda grass is actively growing often wastes nutrients.


Overfertilizing

Too much fertilizer can burn grass and damage root systems.


Uneven Application

Poor spreader technique can create streaks and uneven color.



Ignoring Soil Conditions

Every lawn is different. Soil testing can help identify specific nutrient deficiencies.

Fertilizer and Weed Control Work Together

A thick, healthy lawn is one of the best weed prevention tools available.


Lawns that receive proper fertilization are better able to compete against common San Angelo weeds such as:


  • Crabgrass
  • Dallisgrass
  • Clover
  • Spurge
  • Sandburs (Sticker Weeds)


Healthy turf leaves fewer opportunities for weeds to establish

How Often Should You Fertilize Bermuda Grass?

For most residential Bermuda lawns in San Angelo, three to four fertilizer applications per year are sufficient.


Typical schedule:

  • Spring Green-Up (March–April)
  • Late Spring (May)
  • Early Summer (June)
  • Early Fall (September)


The exact timing may vary depending on weather conditions and lawn health
