Soil drainage is dramatically enhanced by infusing your soil with beneficial bacteria, fungi, protozoa, and good nematodes. Beneficial soil life works together to aerify and improve the permeability of your soil. The best way to improve water percolation and the exchange of air and water is with generous applications of BLEND at 20 to 25lbs per 1,000 sq ft, followed by our PENETRATE Liquid BioTiller at about 8oz per 1,000 sq ft.
