What is the Best Fertilizer for Grass in Spring?

The best fertilizer for spring lawns is one that combines nutrients with weed prevention. A product like 13-0-10 Guardian Pre-emergent is an ideal early spring fertilizer that prevents weeds like crabgrass from germinating. Apply this spring grass fertilizer before the soil temperature reaches 55°F, typically between January 15 and April 1, depending on your location. For best results, applying this early spring lawn fertilizer twice will ensure longer-lasting weed protection.

For lawns that are still dormant, it is important to still apply a pre-emergent.  0-0-7 Safeguard would be the right choice.

Seeding in Spring? Skip the Pre-emergent

If you plan to seed your lawn in the spring, avoid using pre-emergent fertilizers, as they can sterilize the grass seed and prevent it from germinating. Instead, use a balanced fertilizer like 20-0-10 or 10-0-20, which will provide essential nutrients without hindering seed growth. These fertilizers are perfect for promoting healthy growth in newly seeded lawns.

Why Spring Fertilizer for Lawns is Important

Using a spring fertilizer for lawns is critical to kick-starting the growing season. Applying a fertilizer for grass in spring promotes healthy root development, ensures early green-up, and protects against weeds. The best spring lawn fertilizers not only provide nitrogen for growth but also contain higher levels of potassium to help your lawn withstand stress from heat, drought, and disease throughout the year.

Best Grass Fertilizer for Spring: Protection and Growth

Choosing the best grass fertilizer for spring is key to maintaining a healthy lawn all season long. Our spring fertilizers contain iron to promote a dark green color and a blend of multiple nitrogen sources for consistent growth. Potassium, an essential nutrient in our spring fertilizer, supports your lawn’s stress tolerance, making it more resilient to challenges during the growing season. Applying a high-quality spring fertilizer lawn product ensures your grass has everything it needs to thrive.

Application Rate for Spring Lawn Fertilizers

For optimal results, we recommend applying our spring fertilizers at a rate of 4-5 lbs per 1,000 square feet using a broadcast spreader. This ensures even coverage across your lawn and allows the nutrients to penetrate the soil effectively. Following this rate will help your lawn get the right amount of nutrients for healthy growth and weed prevention.  Always water in your fertilizer right after application to move nutrients into the soil so that they can begin working.

Frequently Asked Questions

What is the best fertilizer for grass in spring?

The best fertilizer for grass in spring contains a balanced mix of nutrients, typically with higher nitrogen levels to encourage rapid green-up. A product like 13-0-10 Guardian Pre-emergent is ideal because it provides essential nutrients while also preventing weeds like crabgrass. For lawns that aren't being seeded, this type of fertilizer is highly effective.

When should I apply spring fertilizer to my lawn?

Spring fertilizer should be applied as soon as the soil temperature reaches about 50-55°F. In most regions, this is between January 15 and April 1. Applying a pre-emergent before this temperature ensures weeds like crabgrass are stopped before they can germinate, while the fertilizer promotes early lawn growth.

In early spring, start with a pre-emergent fertilizer like 13-0-10 Guardian. This helps prevent weeds from sprouting while providing your grass with a boost of nitrogen. Apply it using a broadcast spreader at a rate of 4-5 lbs per 1,000 square feet, making sure to apply before soil temperatures hit 55°F.

Should I fertilize my lawn in spring if I’m seeding?

If you’re seeding your lawn in spring, avoid using a pre-emergent fertilizer, as it can prevent grass seeds from germinating. Instead, use a balanced fertilizer like 15-20-10 Starter, 20-0-10 or 10-0-20, which will provide essential nutrients without hindering the growth of your new grass.

Why is spring fertilization important for my lawn?

Spring fertilization is crucial because it provides your grass with the nutrients it needs to recover from winter dormancy and grow strong.
