The proper Spring fertilizer to feed lawns
All-natural, organic-based Natural Alternative® Late Spring Fertilizer 19-0-3 (Application 2 of the five-part Natural Alternative® Lawn Care System) helps keep your lawn green and lush as consistently warmer temperatures heat up the soil. The nutrient combination feeds your lawn for late spring and minimizes quick growth spurts and frequent mowing, promoting even and hardy growth throughout the season. Our organic lawn fertilizer, best for late Spring, is blended with Protilizer®, a seed & plant activator exclusive to Natural Alternative® which strengthens roots and aids in nutrient and water uptake.
Naturally sustainable fertilizer for Spring
Our Late Spring Fertilizer prepares your soil and turf for the upcoming summer heat, as well as the high foot traffic and drought conditions that can accompany the summer months. The zero-phosphorus content of this Spring 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 in the late Spring season.
For Established Lawns: Apply this zero-phosphorus fertilizer in late spring at a rate of 3 lbs. of product per 1,000 square feet. Apply evenly with a calibrated fertilizer spreader. 3 lbs. of this product per 1,000 square feet is equivalent to 0.57 lbs. of nitrogen per 1,000 square feet.
For Newly Seeded Lawns: Rake the fertilizer for late Spring into the upper inch of the soil before seeding. Water until the seed germinates and establishes. Continue with the remaining Natural Alternative® 5-Part Lawn Care System.
