          Bloom Pow Look At Me Now
          Easy application and envy of my neighbors. I’ve been a long time buyer of their full line of products. My garden only gets the best. Soil, lawn and plant food, bloom booster. If they had their own granule weed and feed I would be a fan of that too.

After abt a month my lit starts grow crazy beautiful. Up until it snows. I’m the only person in Ohio with impatience growing until end of nov or Dec. honestly. I just can pull them out

                I use this product in my watering can for all out door plants that bloom and in door plants in general; blooming or not. My Christmas Cactus blooms for three months from early December until late March and my outdoor flowers also extend their blooming season with this product. I am glad to have found it. Recommend Bloom Booster to keep plants healthy with a longer blooming season.
