How To Avoid Those Black Spots!
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 and Pepper plants prefer a pH of 6.0 to 6.8.
If you saw black spots on the bottom of your tomatoes or peppers last spring, they most likely had blossom end rot because your plant wasn't able to get the calcium it needed.
We now have Organic Soil Sweetener and Blossom End Rot Block.
Our Dolomite affects the pH and "sweetens" the potting mix and allows your plants to get all the nutrients they need - and packs a whopping punch of calcium for tomatoes. Best of all, it's not just for Tomatoes, and Peppers, all of your vegetables will benefit from the correct pH level.
