Fertilizer Schedule

San Antonio fertilizer calendar

A year-round fertilization plan for Bermuda lawns in Zone 8b. Adjust based on your lawn's condition and soil test results.

01

Early Spring (March)

Pre-emergent herbicide + light nitrogen

Apply when soil temps hit 55°F in San Antonio. Prevents crabgrass before it germinates.

02

Late Spring (May)

Balanced fertilizer (16-4-8)

Your Bermuda is actively growing now. This is the most important feeding of the year.

03

Summer (July)

Slow-release nitrogen

Light feeding only — San Antonio's heat and humidity stress the lawn. Water deeply after applying.

04

Early Fall (September)

Potassium-rich fertilizer

Strengthens roots before winter dormancy. Last chance for weed control.

Fertilizing in San Antonio

How to fertilize your San Antonio lawn the right way

The most common mistake San Antonio homeowners make is fertilizing at the wrong time. With Bermuda, you want to feed during active growth — never in winter when your lawn is dormant.

Before you buy fertilizer, know your lawn size. The average San Antonio lot is 8,800 square feet, but that includes your house, driveway, and patio. Use LotSite to measure just the grass area — then plug that number into our fertilizer calculator to get the exact bags you need.

For a 8,800-square-foot lot in San Antonio, you'll typically need 2–4 bags of fertilizer per application depending on the product. Over-fertilizing wastes money and can burn your lawn — measuring accurately saves both.
