3 cups of BLEND, topically applied in Spring to the root zone, can powerfully revitalize any shrub. For trees, apply 5 to 10 cups of BLEND in the root zone for maximum health and growth. A sick tree can be remedied with 4 to 5 applications of BLEND at 3 to 6lbs per application, applied topically every 2 weeks, followed by 4oz PENETRATE Liquid BioTiller applied directly over the BLEND in the root zone. The same treatment is effective for sick shrubs. BLEND and PENETRATE are potent ways to revitalize any underperforming tree or shrub via the power of your soil!
