How Often Should You Fertilize Lawns in Summer Heat?

Summer brings intense heat, heavy foot traffic, and drought stress—all of which can deplete your lawn’s nutrient reserves. So how often should you fertilize to maintain that lush green look?

General Guidelines

• Established lawns: Every 4 to 6 weeks with a balanced fertilizer like 10-10-10.
• Fast-growing turf: Every 3 to 4 weeks, especially for cool-season grasses struggling in the heat.
• After heavy rain: Reapply sooner, as nutrients can leach from the root zone.

Best Fertilizers for Summer Lawns

• 21-0-0-24S Ammonium Sulfate Provides a quick nitrogen boost and helps acidify soil.
• 10-10-10 Liquid Fertilizer Ideal for a broad nutrient spectrum, especially when the lawn shows signs of stress.

Application Tips

• Water the lawn before and after application.
• Mow the grass a day before fertilizing.
• Use a broadcast spreader for even coverage.
• Avoid midday application to prevent burn.

Regular fertilization helps your lawn recover from foot traffic, drought, and disease during the summer season. A schedule and the right fertilizer can make all the difference.
