| I think it is "blossom end rott"...
I have several plants in my garden...but I had a few plants left over and dropped them in a large container. the container garden had 6 tomatoes on it. One was nice and red , not real big....but big enough that I couldn't wait...I picked it today....and the bottom was missing and all black. What causes that and how do I stop it?

| I'm not sure if this is the cause. But when I don't mulch my tomatoes -this happens. Something about rain hitting soil and bouncing back on the fruit. |

| I've noticed this happens when we have a dry spell followed by rain. I agree that the mulch helps considerably with this. Maybe it is a soil borne organism like Baumer suggests, I never thought of that...I thought the mulch was helping conserve moisture. |

| Blossom end rot is caused by a deficency of calcium in the soil... Here's a link that will tell you more than you ever wanted to know about it. ;) Diann |

| It can also be caused by uneven watering of the plant, and is sometimes a problem in container grown plants, but it is more common on the first tomatoes the plant produces, the later ones should be ok unless there is a real calcium deficiency or water problem. |

| The CAUSE of Blossom End Rot is calcium deficiency....but that deficiency is most often caused by insufficient water or fluctuations in soil moisture. Potted tomatoes are very suceptable. Linda C |
