We have one of those topsy turvy tomato planter. The plant is huge we had to build a post to hang it. We have many small tomatos, but they all have brown spots either on the top of the tomato or the bottom.. Do you know what the problem is? We are so upset after taking care of this plant for such a long time.

What you describe sounds like blossom end rot, a physiological condition caused by a lack of calcium at the growing tip of the fruit. While your soil may have adequate calcium, fluctuations in soil moisture content from dry to wet really increase the incidence of blossom end rot. It is especially bad on the early fruit each summer and in sandy soils. The damage occurs as cells die at the tip of the fruit. In time (and as the fruit grows) the spots enlarge and turn black. So, by the time you see it, the damage actually has already occurred some time back. Remedies include: having a soil test to make sure calcium levels are adequate, adding organic matter to a sandy soil to increase its moisture holding capacity, keeping plants evenly moist, especially during the development of the first fruits (mulch helps maintain soil moisture), and spraying plants with a Blossom End Rot spray (contains calcium) which can usually be purchased from your local garden center. The tomatoes are still edible. Just cut away the affected portion.
