When Should I Fertilize My Lawn?
A healthy, green lawn doesn’t just happen by chance—it takes care, attention, and the right fertilizer at the right time. Knowing when to fertilize your lawn can make all the difference in achieving that lush, vibrant grass you’ve always wanted.
At OFS, we’re here to guide you through the process and help you maximize your lawn’s potential with our OFS family of lawn fertilizers; Lush Spring Lawn Fertilizer, Replenish Summer Lawn Fertilizer and soil conditioner, and Finale Fall Lawn Fertilizer.
Why Timing Matters
Fertilizing your lawn at the right time ensures that your grass gets the nutrients it needs when it needs them most. Applying fertilizer at the wrong time can lead to poor growth, wasted product, or even damage to your lawn.
To keep your lawn healthy and strong, focus on these key seasons: spring, summer and fall.
Spring - The Growing Season
Best Time - Early to mid-spring (when the soil temperature reaches 55°F)
Spring is the time to wake up your lawn after a long winter. Fertilizing during this period gives your grass the nutrients it needs to grow thick and green.
- When to Fertilize - Watch for the first signs of growth or when the soil temperature reaches 55°F, typically when you notice consistent daytime temperatures of 60°F or higher. This is usually in March or April, depending on where you live.
- How to Apply - Use OFS Lush Spring Lawn Fertilizer to jumpstart root development and promote healthy blades. Apply it evenly across your lawn, and water lightly afterward to help the nutrients soak into the soil.
- Tip - If you’ve recently over seeded your lawn, wait at least 4-6 weeks before applying fertilizer to avoid overwhelming young grass.
Summer - Maintaining Strength
Best Time - Early summer (before temperatures peak)
As the weather heats up, your lawn may experience stress from high temperatures and less rainfall. Fertilizing in early summer helps your grass stay strong and green.
- When to Fertilize - Aim to fertilize in early June through July, before summer’s heat is in full swing. This ensures your lawn has the nutrients it needs to withstand the stress of the season.
- How to Apply - Apply OFS Replenish Lawn Fertilizer in the early morning or evening to prevent burning your grass. Make sure to water your lawn thoroughly after application to activate the nutrients and reduce the risk of scorching.
- Tip - Avoid fertilizing during extreme heat or drought conditions, as this can damage your lawn.
Fall - Preparing for Winter
Best Time - Early to mid-fall (4-6 weeks before the first frost)
Fall is a critical time to prepare your lawn for the colder months. Fertilizing during this season strengthens the root system and stores nutrients to help your lawn survive winter.
- When to Fertilize - Plan to fertilize in September or early October, depending on your location. Look for signs of cooler temperatures and consistent rainfall to determine the best timing.
- How to Apply - Use our OFS Finale Fall Lawn Fertilizer, enriched with calcium & sulfur, to promote soil health and support your lawn’s long-term growth. Apply evenly and water your lawn to help the fertilizer penetrate the soil.
- OFS Tip - Fertilizing in the fall not only protects your lawn through the winter but also ensures it greens up faster in the spring.
