As the weather warms up in Gilbert, it’s time to start thinking about spring lawn care – and that means getting your fertilizer timing right. Properly fertilizing your lawn in the spring sets the stage for healthy, vibrant grass all season long. But when exactly should you apply fertilizer, and what’s the best approach for Gilbert’s unique climate and soil conditions? Let’s dive in.

Understanding Gilbert’s Growing Season
In Gilbert, our warm-season grasses like Bermuda and St. Augustine typically start to green up and actively grow in late March or early April, as soil temperatures consistently reach 65°F or higher. This is the ideal time to begin your spring fertilization, as the grass is primed to absorb nutrients and channel that energy into fresh growth.
However, it’s important not to jump the gun. Applying fertilizer too early, while the grass is still dormant, can lead to wasted product and even encourage weed growth. A good rule of thumb is to wait until you’ve mowed the lawn twice before laying down your first round of spring fertilizer.
Choosing the Right Fertilizer Formula
For that initial spring application, look for a balanced fertilizer with an NPK ratio around 15-15-15. This provides an equal mix of nitrogen for leaf growth, phosphorus for strong roots, and potassium for overall plant health and stress resistance. Many Gilbert lawn care experts recommend a slow-release formula that feeds the grass steadily over several weeks.
As the season progresses, you can transition to a fertilizer higher in nitrogen, such as a 20-5-10 blend, to really push top growth and give your turf that lush, carpet-like look. Just be careful not to overdo it – too much nitrogen can lead to excessive growth, thatch buildup, and even fungal diseases in Gilbert’s hot, humid summers.
“The key to successful spring fertilization in Gilbert is patience and moderation. Wait for the grass to wake up fully, then feed it consistently with a balanced, slow-release product. You’ll be rewarded with a lawn that looks and feels its best all season long.” – Marcus Wynn, YardBonita Lawn Care Expert
Proper Fertilizer Application Techniques
How you apply your fertilizer is just as important as when you apply it. Always use a calibrated spreader to ensure even coverage, and avoid spreading fertilizer on windy days or near water features. Water the lawn thoroughly after application to help move nutrients into the soil, but don’t fertilize before a heavy rain that could wash the product away.
For best results, consider splitting your fertilizer into smaller, more frequent applications every 6-8 weeks throughout the growing season. This provides a steady nutrient supply without overwhelming the grass. And don’t forget to follow other essential spring lawn care practices, like proper mowing, irrigation, and weed control, to keep your Gilbert lawn looking its absolute best.
