When to Fertilize Your Lawn in New Jersey

If you want a thick, healthy lawn in Monmouth County, fertilizing at the right time is half the battle. But how do you know when to fertilize your lawn in New Jersey?

Let’s break down the best months for each type of fertilizer, what products to use, and how to avoid common mistakes.

🗓️ Best Time to Fertilize Lawns in NJ

New Jersey has a mix of cool-season grasses like Kentucky bluegrass and tall fescue. These grasses thrive in spring and fall.

✅ Spring (April–May)

• Use a slow-release fertilizer to boost growth as grass comes out of dormancy.

• Look for a balanced NPK ratio, like 20-5-10.

✅ Fall (September–October)

• Fall fertilizing strengthens roots for winter and gives you a jump-start on green grass in spring.

💡 Pro Tip: Avoid Mid-Summer Fertilizing

Too much nitrogen in hot weather can burn your lawn. Instead, focus on proper watering and mowing during July and August.

🌱 Types of Fertilizers to Consider

• Granular vs. Liquid – Granular is slow-release; liquid works fast but needs more frequent applications.

• Synthetic vs. Organic – We often recommend organic fertilizers for long-term soil health.

🚫 Common Fertilizing Mistakes to Avoid

• ❌ Fertilizing right after mowing (wait 24–48 hrs)

• ❌ Over-fertilizing and burning the grass

• ❌ Not watering after applying granular fertilizer
