Review: 10 STARS! The Red Rocker Inn has reopened and is located in black Mountain, NC, not Montreat, - This fertilizer is amazing if you want instant and continuous blooms all summer! My hibiscus, geranium, begonia, and vinca plants all love it. I have used this since 1992 when a restaurant owner told me about it while he was fertilizing his impatiens in front of The Red Rocker in Montreat, NC. (The restaurant is no longer there, sorry to say.)
Review: This stuff really works!! - This product is amazing! Easy to use and works fantastic. Within ten days, my mandevilla was covered with blossoms. Definitely worth the cost.
