We service landscapes for liquid fertilizing and weed control from Flagstaff AZ to the Phoenix area. As a landscape professional for over 40 years, I know what I need in a fertilizer product. I can tell when a product is doing more than just fertilizing. With Biofeed, I see healthier foliage on the lawns, trees and plants that we root-feed and foliar spray but I can also see an improvement in the soil texture and the improvement in water penetration and the improved water holding capacity of the soils we treat with Biofeed. I may not understand everything it is doing but I know that when I put it down, it works with the soil and helps it do its natural thing and you can see and feel that the soil is alive. I strongly recommend Biofeed products for everything you grow!
