Cures Blossom End Rot in Tomatoes & Peppers. OMRI Listed : Patio, Lawn & Garden Review: Satisfied - I have used this on several lawns. It's not a miracle grower, it just conditions my dirt and it does take awhile to see improvements. But they do happen. Satisfied. Review: It qorked - I purchased this when I found blossom rot on my container-planted tomatoes. It was easy to apply, by just spreading the granules over the top of the soil. The substance dissolves over time with watering, and seemed to be the fix for my problem. It stopped any newer tomatoes on affected plants from developing the rot, and did not spread to the other tomatoes in the garden. ## Features - OMRI Listed - Cz Gypsum Calcium Sulfate Dihydrate is an All-Natural mineral fertilizer listed by the Organic Materials Review Institute (OMRI).
