What can I do to prevent black spots (BER) on the bottom of my tomatoes?Updated a year ago

The black on the bottom of your tomatoes is called Blossom End Rot (BER). It is caused by a lack of calcium and other ingredients in the growing media. Adding 1 pound of Dolomite to the growing media before planting (as in the instructions) can help prevent BER from forming. In the event BER still presents itself, mix ¼ cup of hydrated lime or pickling lime with one gallon of water and add it to the reservoir the next time you fill your EarthBox with water. Do this only once and pick off the affected tomatoes. This may also occur with other “seeded” vegetables, such as peppers.

We also offer our EarthBox Tomato & Veggie Boost, which is a weekly calcium nitrate additive that helps protect against and preventing BER.
