Rotting tomatoes (vegetables, peppers, leaves, planting)

[cricketfan]

My potted tomato plants are all producing but the young green tomatoes all seem to be rotting at the base. Too much water? Too little water? Too much sun? Does anyone know the answer?

Could be any number of things. Have you gotten a lot of rain lately? Then it could possibly be Black Mold caused by the moisture.

I used to have a problem w/the end rot, I can't recall now whether it was too much acid or too much sulfur - what are they potted in? Are the pots large enough?

No, haven't had much rain but I do water when the leaves look a bit limp.

Yes, the pots are very large and the soil is treated. No problem there.

you might want to try replanting them in some different soil, i had to do that last year the had black mold at the bottom .
Good Luck

You probably are experiencing "blossom end rot" brought on by a lack of calcium.

Sounds like you need a fungicide for vegetables.

I agree with nitram.
Sounds like blossom end rot to me. The one time my tomatoes had it years ago, it was obviously because of fluctuating soil moisture.
Snippet:
Blossom-end rot is a common, nonparasitic, physiological disorder that occurs on tomatoes, peppers, eggplant, and some melons. Blossom-end rot is a symptom of calcium deficiency in the fruit. It may be caused by low soil calcium, low levels of calcium in the maturing fruit, or other cultural factors -- particularly fluctuating soil moisture. This disorder is usually most severe following extremes in soil moisture (either too dry or too wet). These conditions result in a deficiency of calcium available to the maturing fruit, at the spot where damage becomes apparent.

Thanks to all who suggested "blossom end rot" to be the problem. Lack of calcium looks to be the culprit. Quite inadvertently the plants were being watered with a water source that was conditioned to remove lime. Anyway, I now know what I have to do correct it. Unfortunately too late for the more matured fruit.

Thanks, all.
