Start with Grow starter fertilizer for enhanced establishment of new sod and seed. Designed for sodding, sprigging and seeding where soils lack the nutrients required for fast establishment. Rooting, plant strength and resistance to stress will all be enhanced with Grow. Grow is designed to 1) enhance microbial activity in the soil through micronutrients, carbon, and amino acids. 2) provide new sod roots what they need to grow. It is not intended to promote top growth or green up. It is also the product that we recommend be used in the fall prior to dormancy or snow cover to provide the plant root zone the nutrients needed for winter and a successful start to spring.
