Maintaining a lush, green lawn in the St. Louis area requires more than just regular mowing and watering—it requires proper fertilization throughout the year. The unique climate and soil conditions in St. Louis mean that your lawn has specific needs that change with the seasons. In this guide, we’ll walk you through the best practices for fertilizing your lawn throughout the year to ensure optimal growth and health.
Spring: Preparing for Growth
Spring is the time when your lawn comes back to life after the winter dormancy. It’s essential to give your grass a strong start by applying a balanced fertilizer that provides nitrogen, phosphorus, and potassium—the key nutrients for healthy growth.
- When to Fertilize: Late March to early April, as soon as the grass starts to green up.
- What to Use: A balanced, slow-release fertilizer (e.g., 10-10-10 or 15-5-10).
- How to Apply: Spread evenly across the lawn using a broadcast spreader, and water thoroughly to help the nutrients absorb into the soil.
Summer: Maintaining Health
The hot and humid summer months in St. Louis can stress your lawn. To keep it healthy, you’ll need to apply a lighter dose of fertilizer that focuses on maintaining growth without overfeeding the grass.
- When to Fertilize: Late June to early July, when summer heat begins.
- What to Use: A slow-release fertilizer with a lower nitrogen content (e.g., 5-10-5).
- How to Apply: Apply in the early morning or late evening to avoid the heat of the day, and water deeply after fertilizing.
Fall: Building Strength
Fall is perhaps the most important season for fertilizing your lawn in St. Louis. As the temperatures cool, your grass will focus on root development, making it crucial to provide the nutrients it needs to build strength for the winter ahead.
- When to Fertilize: Late September to early October, when the weather cools down.
- What to Use: A high-nitrogen fertilizer with a slow-release formula (e.g., 20-8-8).
- How to Apply: Spread evenly and water thoroughly. This is also a great time to overseed any thin areas of your lawn.
Winter: Protecting the Lawn
During the winter months, your lawn will go dormant. While you don’t need to fertilize during this time, preparing your lawn in late fall with a winterizing fertilizer can help protect it from the harsh winter conditions.
- When to Fertilize: Late November to early December, just before the first frost.
- What to Use: A winterizing fertilizer with a high potassium content (e.g., 0-0-60).
- How to Apply: Apply evenly across the lawn, and water lightly if the ground isn’t frozen.
