BLEND generously applied at about 30lbs per 1,000 sq ft before, during, or right after planting is excellent for maximizing yields and minimizing pests and disease. If your soil is extremely light or extremely dense and heavy, PENETRATE Liquid BioTiller applied over the soil surface (right after BLEND application) will significantly improve problem soils. Don’t worry, if PENETRATE gets on plant leaves, it will not harm them!
