I have been using Biofeed on my customers landscapes as well as on my own yard for over 30 years! I met Dan Lee the founder of Biofeed back when I started my business and his Biofeed products have helped the growth of my business. Thanks to Biofeed several of my customers yards have won top awards and have been featured in Phoenix Home and Garden magazine with top honors! If you want to give your customers the very best, then use Biofeed!
