When to Fertilize Bermuda grass in Texas
Bermuda grass benefits from adequate fertilization to strengthen its roots and produce a gorgeous bed of blades. If you’ve chosen Bermuda to cover your lawn, learn more about how best to care for it.
Choosing the best fertilizer can get pretty detailed. For some serious science, check out this article on applying types of fertilizers. However, we want to help break it down into useful information.

The first application for Bermuda grass should be done in February or March, with a pre-emergent fertilizer. The second fertilization is typically applied around April or May.
How often you fertilize depends on what you use. Some fertilizers have a longer residual period than others, requiring fewer applications per year. Read your labels and check with a professional if you aren’t sure what your grass needs.
Summer is best for post-emergent fertilizer applications, ending around mid-September. There are some Bermuda grass hybrids that need special care and should be fertilized more frequently compared to others. If you’ve chosen such a type for your lawn, add another treatment of pre-emergent fertilizer around September-October.
The most common ingredients found in fertilizers for Bermuda grass are nitrogen, potassium, and phosphorus. Organic fertilizers include soybean and cottonseed meal, which have high nitrogen levels.
Synthetic fertilizers include cornmeal and urea. Urea has small amounts of nitrogen which releases easily into the soil.
General Fertilization Times:
- February-March: Fertilizer with Pre-Emergent
- March-April: Fertilizer with Pre-Emergent
- May: Fertilizer with Post-Emergent
- June: Prebiotic Fertilizer with Grub Treatment
- July: Fertilizer with Post-Emergent
- September: Probiotic Treatment Fertilizer
- October: Fertilizer with Pre-Emergent
These examples are only meant to give you a general idea of when to fertilize Bermuda grass, and the types of fertilizer to use. You may find that different types are needed, depending on your situation. For example, if you don’t have any weeds at all, then the post-emergent treatment wouldn’t be needed.
Let us take an in-depth assessment as to the exact times that Bermuda grass can be fertilized in Texas, with the fertilizer types.
February through May: Apply after the leaves in your yard have turned green. The measurement should be ½ to 1 pound of nitrogen (N) per 1000 square feet. Test the soil to know the amount of nutrient and the amount of lime to add.
If soil samples are not available, go for the full amount of nitrogen-phosphorus-potassium (N-P-K) turf fertilizer, with a ratio of 4-1-2. A good example is the 16-4-8. Lime can be added if need be, based on your soil type.
If you want to know the amount needed to use 1 pound of nitrogen in every 1000 square feet, you need to divide 100 by the first number that appears in the fertilizer ratio. For instance, if the fertilizer is 16-4-8, simply divide 100 by 16 and the result is 6.25 pounds of fertilizer in every 1000 square feet.
June through August: Apply ½ to 1 pound of N in every 1000 square feet at least every 4 to 8 weeks.
September through November: If there are low levels of potassium (K) and it is September, apply 1 pound of potassium (K20) per 1000 square feet. Use muriate of potash (0-0-60), potassium sulphate (0-0-50) or Sul-Po Mag (0-0-22).
December through February: Never fertilize any Bermuda grass that has not yet been over-seeded. Apply ½ pound of nitrogen in every 1000 square feet in the months of December and January only to over-seeded Bermuda grass.
