Blossom-end Rot is What's Wrong with Your Tomato Plant

About this time of year I started getting the same question from new gardeners. In particular, new gardeners who are growing their own tomatoes for the first time start to panic when they notice a brown spot start to develop on the bottom of their tomato fruits. "What's wrong with my tomato plant" they all ask after noticing a small,brown spot beginning to form on a tomato fruit. It's blossom-end rot.
