Review: This Product works. - Transplant Shock. I have tees thst need this product whenever transplanting. I don't use this as a fertilizer. But it does ignite plant growth I noticed. It is one of the gest products so far for both transplant shock preventative, plant and root growth. I ran out but would like to buy it again. Fertilizer quality: It has unexpected and excellent Quality. I get big leafes. Size: I live in a small space so the size of the product suited my situation. I am sure they come in different sizes, for different needs. I ran out and brought one on thr fly from Home Depot. Really not the same Quality. I said to myself, I wish I had this one again. I ran out. Happy this review came up so I can add this to my cart.
Review: Good natural fertilizer with great results. - My husband swears by this product. Makes our flowers bloom like mad. It's easy to use and lasts quite a while, depending on how many flowers/plants you're treating.
