Tomatoes rotten on bottom
In at least one of the tomato plants in my garden, the tomatoes are growing badly. By this I mean that once they just start turning red, they are thouroughly rotted out at the bottom, without being anywhere near touching the ground. Nor, I should mention, has it been particularly rainy as of late.
Luckily, other tomatoes are growing in perfectly well. I just really hope that whatever is making the others rot doesn't ever spread (fingers crossed). What is causing this? It doesn't seem to have to do with visible pests.
Thanks a million!
