Root Growth Stimulant (with humic acid and sea kelp)
Great for soil health and root stimulation
Product Description: RGS is a root growth stimulant with sea kelp and humic acid is our primary bio-stimulant offering for use in lawns and landscapes. Formulated by John Perry of Greene County Fertilizer Co, RGS is the foundation of all Lawn Care Nut and Yard Mastery programs.
If you are new to spraying liquids on your lawn, this is a great one to start with. It won't "burn" the lawn or anything like that - and RGS is the best to start with anyway since it aids in soil health and stimulates roots in turf. If you have challenges with your grass holding on during summer heat, getting RGS into the soil will help it through the stress. RGS is truly the backbone of the bio-stimulant program, hands down, and has the highest concentration of sea kelp hormones in the line. It was designed to increase rooting and decrease stress pressure caused by heat and drought. It will also feed microbial life in the soil which helps to optimize your fertilizer treatments.
"N-Ext" is the name of this line of products and N-Ext stands for "Nitrogen Extension." RGS, Root Growth Stimulant, is kind of like the "base layer" of that line because it contains humic acid and sea kelp, the two primary bio-stimulants we recommend. The biologically active material contains humic acid and sea kelp to aid in initial spring green-up, buffer and extend nitrogen release rates, and add oxygen to the soil profile for greater nutrient uptake.
Can be applied at any time during the growing season for cool and warm-season lawns. Custom timing and recommendations are available in our app.
RGS can be used on all grass types, including the following: Cool Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass Warm Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia
