Why This Fertilizer?

This natural-based fertilizer is designed to feed lawns while helping them withstand the challenges of summer. The balanced nutrient profile provides steady nutrition without excessive top growth, while kelp extracts supply natural biostimulants that encourage stronger root systems and improved stress tolerance. Kelp has long been used in turf management because it supports plant health during periods of heat, drought, and heavy use. This formula is ideal for maintaining steady growth and improving resilience when lawns are under environmental stress.

Technical Details

Organic fertilizers contribute nutrients while simultaneously improving soil biological activity. Research conducted through the University of Guelph Turfgrass Institute has shown that organic nutrient sources can increase microbial activity within the turfgrass rhizosphere, enhancing nutrient cycling and improving soil structure over time. Increased microbial activity improves the gradual release of nitrogen and other nutrients, supporting steady plant growth without the rapid flush associated with highly soluble fertilizers.

The addition of kelp extract introduces naturally occurring plant growth regulators such as cytokinins and betaines. Studies summarized by the Penn State Center for Turfgrass Science indicate that seaweed-derived biostimulants can stimulate root growth and improve turf recovery following drought and heat stress. By combining organic nutrition with kelp-based biostimulants, this formulation supports both plant health and soil biology during periods of environmental stress.

"I used seed and fertilizer from The Lawn Medic in the Spring. The transformation over about 5 weeks was incredible. The pictures tell the story. The new lawn came in thick and green and it has stayed that way all year. No weeds. Strong growth."
