Helps keep your lawn green and lush

Fortified with Protilizer® for supercharged results.

The proper diet

Natural Alternative® Late Spring Fertilizer 19-0-3 (Application 2) helps keep your lawn green and lush as consistently warmer temperatures heat up the soil. The nutrient combination for late spring minimizes quick growth spurts and frequent mowing, promoting even and hardy growth throughout the season. This fertilizer is blended with Protilizer®, a plant supplement exclusive to Natural Alternative® which strengthens roots and aides in nutrient and water uptake.

Naturally sustainable

Our Late Spring Fertilizer prepares your soil and turf for upcoming summer heat, as well as the high foot traffic and drought conditions that can accompany summer months. The zero-phosphorus content of this fertilizer won’t contribute to algae blooms in nearby bodies of water, making Natural Alternative® fertilizer the more sustainable way to grow a lush lawn.
