However, fertilizing a lawn in summer can have both positive and negative effects, depending on several factors such as the type of fertilizer used, the frequency of application, and the specific needs of the lawn. In this article, we will delve into the details of what happens when you fertilize a lawn in summer, exploring the benefits, risks, and best practices to ensure a lush, thriving lawn.
Understanding Lawn Fertilization
Lawn fertilization is the process of applying nutrients to the soil to promote healthy plant growth. Fertilizers typically contain a combination of nitrogen, phosphorus, and potassium (NPK), which are essential for plant development. Nitrogen promotes leaf growth and color, phosphorus supports root development and flower production, and potassium enhances overall plant health and resistance to disease. During the summer months, lawns often require additional nutrients to cope with the increased demand for growth and to recover from the stress caused by high temperatures, drought, and heavy use.
Benefits of Summer Fertilization
Fertilizing a lawn in summer can offer several benefits, including:
– Enhanced growth and color: Summer fertilization can promote a denser, greener lawn by providing the necessary nutrients for blade growth and chlorophyll production.
– Improved stress tolerance: Lawns that are well-fertilized during the summer are better equipped to withstand stressors such as heat, drought, and pests.
– Recovery from summer stress: Summer can be harsh on lawns, with conditions like heat stress and drought causing damage. Fertilization can help the lawn recover from these stresses, promoting new growth.
Risks and Challenges of Summer Fertilization
While fertilizing a lawn in summer can be beneficial, there are also potential risks and challenges to consider:
– Burning the lawn: Applying too much fertilizer, especially during hot weather, can burn the lawn, causing damage or even killing the grass.
– Promoting weed growth: Fertilizers can also feed weeds, leading to an increase in their growth, which can outcompete the grass for nutrients, water, and light.
– Environmental impact: Excess fertilizer can leach into waterways, contributing to algae blooms and water pollution, highlighting the importance of choosing environmentally friendly options and following application guidelines.
Best Practices for Summer Lawn Fertilization
To maximize the benefits of summer fertilization while minimizing the risks, it’s essential to follow best practices:
Choosing the Right Fertilizer
The type of fertilizer used can significantly impact the outcome of summer fertilization.

Additionally, drought-stressed grass is more susceptible to disease and pest issues, and fertilization can exacerbate these problems. It’s best to wait until the drought has ended and the lawn has received adequate rainfall before fertilizing.
If you must fertilize during a drought, make sure to choose a fertilizer that is specifically designed for drought-stressed lawns. These fertilizers typically contain ingredients that help to retain moisture in the soil and reduce stress on the grass. It’s also essential to follow the recommended application rates and water the lawn thoroughly after fertilization to prevent burning and ensure the fertilizer is absorbed evenly. However, it’s still important to note that fertilizing during a drought is not ideal, and it’s best to wait until the lawn is receiving adequate moisture before fertilizing.
What type of fertilizer is best for summer fertilization?
The best type of fertilizer for summer fertilization is a slow-release fertilizer that is high in phosphorus and potassium and low in nitrogen. This type of fertilizer provides a steady supply of nutrients to the grass over an extended period, reducing the risk of burning and promoting healthy growth. Phosphorus and potassium are essential for root development, disease resistance, and overall plant health, making them ideal for summer fertilization. Additionally, a slow-release fertilizer helps to reduce the risk of leaching and runoff, which can pollute waterways and harm the environment.
When selecting a summer fertilizer, look for products that contain ingredients such as sulfur-coated urea, polymer-coated urea, or other slow-release nitrogen sources. These products release nitrogen slowly over time, providing a steady supply of nutrients to the grass without causing excessive growth or burning. It’s also essential to choose a fertilizer that is specifically formulated for your lawn type, whether it’s cool-season, warm-season, or a mix of both.
