A healthy, vibrant lawn is a source of pride for any homeowner or landscape professional. While choosing the right fertilizer is an important first step, understanding when and how to apply it is just as crucial. Proper fertilizer application timing can make the difference between a thriving turf and a stressed, unhealthy lawn. At GCO Landscape Supply, we know that the unique climate of the Gulf Coast requires a strategic approach. Applying nutrients at the correct time ensures your grass gets what it needs to grow strong roots, resist pests and diseases, and maintain a beautiful green color. Let’s explore a seasonal guide to timing your fertilization for optimal results.
Spring: The First Feeding
As your lawn emerges from its winter dormancy, it is hungry for nutrients to kick-start its growth. The first fertilizer application of the year, typically in early spring, should focus on promoting top growth and root development. For warm-season grasses common to our region, such as Bermuda, Zoysia, and Centipede, this application is a crucial part of a comprehensive program. It helps the grass green up and prepares it for the demanding summer heat. The ideal fertilizer application timing in spring is after the last chance of frost has passed and the grass has fully come out of dormancy, which is generally between mid-March and early April. This timing prevents you from wasting nutrients while the grass is still dormant.
Summer: Maintaining Momentum
The intense heat and humidity of a Gulf Coast summer can put a lot of stress on your lawn. Fertilizing during this period is all about maintenance and strengthening. A second application in late spring or early summer, typically around late May or June, helps your lawn maintain its vigor without promoting excessive growth that would make it vulnerable to stress. This application helps replenish nutrients lost during the initial growth spurt and prepares the grass to withstand the long, hot days ahead. Proper fertilizer application timing in the summer is critical to avoid burning your lawn, so we recommend a slow-release granular product that provides a steady feeding and is applied when temperatures are not at their peak.
Fall: The Most Important Feeding
While many people stop thinking about their lawns as the weather cools, fall is arguably the most important time for fertilization. The final application of the year should occur in early to mid-fall, around September or October. At this time, grass roots are actively absorbing nutrients to store for the winter. A fertilizer with a higher potassium content helps prepare the grass for cold weather, strengthens the root system, and enhances disease resistance. The term “winterizer” is because it gives your lawn the stored energy to survive the winter and green up quickly in the spring.
Winter: The Dormancy Period
During the winter months, most warm-season grasses go dormant. At this time, you should refrain from applying any fertilizer. The grass is not actively growing or absorbing nutrients, so any product applied would be wasted and could potentially run off into storm drains and local waterways. The key to successful fertilizer application timing is understanding that there are periods of dormancy where no application is needed. Instead, focus on keeping the lawn clear of debris and ensuring the soil is ready to absorb nutrients in the spring.
