My tomatoes have black rot (fertilizer, nursery, leaves, plants)

[smoky_topaz]

Seriously....out of about six tomatoes....only one was good, the rest had a smushed , brown bottom.. I'm told it is black rot. Suggestions?

I think I may have to watr them more infrequently...like every othr day rather than every day. Where I live it is so hot and humid I just hate seeing how dry the leaves look.

I am glad you asked this question.....I want to know the answer too.

I believe this is a calcium deficiency, had it several years ago, there is a calcium spray you can get, will cure this problem, go to your local feed store and ask what they have for blossom end rot.

Low calcium. You may just not be watering them evenly (i.e. lots of water for a week, then neglecting them for 1.5 weeks before you start watering again). Make sure you water them every 2 days. If that doesn't work try crushing up some Tums tablets and spreading it around them. Also try some mulch around them to help retain moisture. My guess is that it is mostly likely due to improper watering.

I read somewhere that when you water the tomatoes, just water the roots. Try not to get the leaves wet. We have been doing that this year, and they look good, so far. It has been hot and dry here too.

We had that happen last year to our tomatoes and it was very frustrating. We added some sort of tomato fertilizer we received from our local garden supply regularly and the issue corrected itself. We have yet to experience that this year. But, we are in a different area and actually started our tomatoes from seed rather than buying the plants from a nursery like we did in previous years. Tomatoes usually need a lot of water and love the heat so I would be careful not to let the roots dry out too much.
