Florida’s Unique Climate

First, it’s important to recognize that the Florida growing conditions are unlike those in other regions due to the state’s:

1. Subtropical climate
2. High heat and humidity
3. Frequent rainfall
4. Sandy soil

To keep your Florida lawn thriving, it’s essential to understand how these unique characteristics affect your choice of grass and its maintenance needs.

• Year-Round Growth: Warm-season grasses, such as St. Augustine, Zoysia, and Bermuda, thrive in Florida’s climate, but they also require year-round maintenance. During summer, grasses grow quickly and need frequent mowing, while in the cooler winter months, growth slows down. Frequent mowing in hot conditions also stresses the grass, so it’s essential to keep mower blades sharp and mow in the cooler parts of the day.

• Irrigation: Florida’s climate can be dry during the winter and rainy during the summer. Lawns require careful irrigation management, especially in the drier months. In summer, rain often provides sufficient water, but consistent rainfall can also lead to over-saturation, causing fungal diseases. Allowing the grass to dry between waterings and avoiding watering in the evenings can help prevent fungal issues.

• Fertilization: Florida’s long growing season means that lawns need regular fertilization to stay healthy. Using a lawn fertilizer like GreenEdge, which is environmentally friendly and has slow-release nutrients, helps maintain a balanced nutrient supply and prevents runoff during heavy rains. It also adds organic matter to the soil, improving water retention.

• Pest Control: Warm, humid conditions create an ideal environment for pests and diseases, such as chinch bugs, mole crickets, and fungal issues. Regular monitoring and proactive treatments are essential to prevent lawn damage.

• Weed Control: Weeds tend to grow rapidly in Florida’s climate, particularly in summer. Pre-emergent herbicides and consistent lawn care practices, such as mowing and fertilizing, can help control weed growth.

• Soil Health: The sandy soil in much of Florida drains quickly but doesn’t retain nutrients well. Organic fertilizers like GreenEdge improve soil structure, boost nutrient retention, and reduce the need for frequent watering.

• Soil Compaction: Heavy rains, combined with the frequent traffic on the lawn, can lead to soil compaction. Compacted soil makes it harder for grass roots to grow and absorb water and nutrients. Aerating the lawn once or twice a year helps alleviate compaction, allowing for better air, water, and nutrient movement through the soil.

Choosing your Grass Seed: Warm Season Grasses

Choosing the right grass type is critical. Warm-season grasses like St. Augustine, Zoysia, and Bahia are well-suited to Florida’s heat and humidity. These grasses are drought and heat tolerant, making them ideal for Florida weather.

Mowing: Maintaining a Healthy Lawn

Lawn maintenance in Florida is a year-round commitment, especially with the rapid growth that occurs during the rainy season. Regular mowing is essential, but remember to adjust your mowing height based on the grass type. Cutting your grass at the proper height encourages deep root growth and helps keep weeds at bay, ensuring your Florida lawn stays healthy and resilient. Here are general suggestions for warm season grasses⁷:

The one-third rule is a popular guideline for maintaining a healthy lawn. Adhering to this rule ensures that the grass keeps enough surface area for photosynthesis (Grass is still a plant after all!). Cutting too much can reduce this natural process and add stress to the plant, increasing the need for more fertilizer treatments later on. Additionally, keeping a longer grass height leaves less room for weeds to thrive and increases healthy root development⁸.

Irrigation: Proper Watering Techniques for a Thriving Florida Lawn

Watering your Florida lawn correctly is crucial to its health and longevity. Although Florida sees frequent rain, it’s important to supplement natural rainfall with proper irrigation, especially during the dry season. Deep, infrequent watering is the key to encouraging strong root development. Aim to water your lawn deeply once or twice a week rather than lightly every day. This method helps your grass develop deeper roots, making it more drought-resistant and less prone to diseases.

The best time to water your Florida lawn is early in the morning, before the sun intensifies. Watering at this time allows your grass to absorb moisture efficiently while preventing issues like fungal growth, which can occur if your lawn stays damp overnight. Consider using a sprinkler or irrigation system for even water distribution. However, avoid overwatering, as it can lead to shallow roots, thatch buildup, and increased vulnerability to pests. Striking the right balance will help you maintain a vibrant, healthy lawn that can weather Florida’s changing seasons.

Fertilizer: Choosing the Right Nutrition for a Lush Florida Lawn

Think of fertilizer as the food your plants need to grow. Just like our own food, there are huge variations in the nutritional value and the impact on the environment. Fertilizer often comes with a negative connotation and for good reason. Overapplication of nutrients, incorrect fertilization, and a lack of education can have very real and serious consequences on both your yard and the environment. It’s important to make sure you are choosing the right lawn fertilizer for your yard, applying at the right time, and in the correct amount.

Lawn Fertilizer Considerations

GreenEdge fertilizer uses patented slow-release mechanisms to prevent run-off and require less applications per year. While 6% or 8% nitrogen may be lower than leading products on the market, it may be all you need. GreenEdge fertilizers are considered “enhanced-efficiency” products that continue to release nutrients for up to 12 weeks after application. Whether you select GreenEdge or another brand, make sure to apply only what you need to keep your local waterways safe and thriving.

Common Fertilizer Mistakes to Avoid:

• Over-Fertilizing / Overapplication: Applying too much fertilizer can burn the grass, cause excessive growth, and lead to nutrient runoff into waterways, which harms the environment. It’s essential to follow recommended application rates.

• Using the Wrong Type of Fertilizer: Not all fertilizers are suitable for all grass types or lawn conditions. Some homeowners use a fertilizer with the wrong nutrient balance, which can lead to uneven growth, weak grass, or even damage. Choose a lawn fertilizer that matches the specific needs of your grass.

• Fertilizing at the Wrong Time: Fertilizing too early or too late in the growing season can be ineffective. Grass should be actively growing when fertilizer is applied, so avoid fertilizing during dormancy. In Florida, the best time to fertilize is in the spring when warm-season grasses are in their peak growth. Be careful to avoid fertilizing in black-out periods. Check with your locality before applying.

• Not Watering After Fertilizing: Failing to water after applying fertilizer can prevent the nutrients from reaching the roots. In some cases, the fertilizer may sit on top of the soil and burn the grass. Light watering after fertilization ensures proper absorption.

• Uneven Application: Spreading fertilizer unevenly can result in patchy growth, with some areas receiving too much fertilizer and others too little. Using a broadcast spreader and applying in overlapping patterns helps ensure an even distribution of nutrients.

• Ignoring the Weather: Applying fertilizer right before heavy rain can wash away nutrients, leading to waste and environmental harm due to runoff. It’s best to check the weather forecast and apply fertilizer when there’s no imminent heavy rain.

• Not Testing Soil: Many homeowners skip soil testing, which can lead to over-applying nutrients the lawn doesn’t need or under-applying the ones it does. A soil test helps determine what nutrients are lacking so you can apply the right type of fertilizer in the correct amounts. Check out the UF/IFAS soil testing lab for options.

• Fertilizing Newly Planted Grass: Fertilizing grass right after seeding or sodding can damage the young roots. It’s better to wait until the grass is well-established before applying fertilizer.

• Using Quick-Release Fertilizers: Quick-release fertilizers provide an instant boost but can also lead to rapid, excessive growth that stresses the grass and requires frequent mowing. Slow-release fertilizers like GreenEdge offer a steady supply of nutrients, reducing the risk of burning the grass and promoting long-term health.

• Ignoring Lawn Size: Homeowners often apply fertilizer without considering the actual size of their lawn, leading to over-application. Accurately measuring the lawn and calculating the correct amount of fertilizer for that space is crucial.
