Most Potting Mixes are formulated using Sphagmum Peat moss. Sphagnum is naturally very acidic, with a pH of 3.5-4.5. (High acidity means the same as low pH.) which causes the nutrients to be ‘locked” into the mix and unavailable to your plants. Tomato plants prefer a pH of 6.0 to 6.8. If you see a black spot on the bottom of your tomatoes or peppers, they most likely have blossom end rot because your plant isn’t able to get the calcium it needs. Our Dolomite “sweetens” the potting mix and allows your plants to get all the nutrients they need and packs a whopping punch of calcium for tomatoes.
*** Use one bag of Organic Soil Sweetener and Blossom End Rot Block per GrowBox™.
*** Use in addition to our Nutrient Patch™, this is not a substitute for fertilizer.
Did you know that if you combine your Dolomite purchase with at least one more Grow Box™,
there’s no additional shipping in most cases. Why not expand your garden and garden harvest now?

I love this product. I added dolomite to a raised garden I had built a couple years ago. My tomato plant that I planted in November is already over 6 feet tall. It’s covered with tomatoes and I picked one tomato that weighed 28.4 oz. Amazing!

We always had wonderful success with our Growboxes but certain types of tomatoes seemed to be prone to Blossom End Rot. No more. We tried the dolomite tratment and never had an issue since, on any of the tomato varieties we planted. I don’t take anymore chances. We use the Dolomite treatment with every tomato dedicated Growbox!
