Lawn and Garden Formula

Item#: 212R

Picture your dream lawn and gardens growing beautiful, vibrant plants of all types. A yard with green, lush grass that’s tough enough and vigorous enough for kids, pets, and wildlife to enjoy every day. Flower beds brimming with color. Fruit and vegetable plants growing strong and producing good tasting food the kids will eat again. Vigorous, strong trees and shrubs to shade and beautify your grounds. 


Bio S.I. Lawn and Garden Formula helps you make that dream image a reality—without causing any environmental harm.


Bio S.I. Lawn & Garden Formula is a liquid soil inoculant with a broad and diverse spectrum of naturally occurring beneficial soil-derived microbes that help rebuild the soil. Bio S.I. Lawn & Garden Formula will help soften your soil by improving the organic matter (humus) layer of the soil. This allows your soil to hold water and nutrients better, which may help reduce water bills, chemical use, and improve your lawn's environment for your family, your pets, and your neighbors. Bio S.I. Lawn and Garden Formula will also reduce thatch build-up by breaking down the plant debris left behind after each mowing.

For faster results, we recommend also adding Bio S.I. Lawn and Garden Select in your fertilizer program.




One quart covers up to 5,000 square feet.


Use in spring (February/March), early summer (May/June), summer (July/August) and fall (October/November).


Apply with a quality hose-end or pump-up sprayer, or inject into an irrigation system that is calibrated to the right application.


One Size Does Not Fit All

Bio S.I. products come in a variety of sizes to meet your needs.
