Hey everyone hope you are doing well this wonderful Monday! I am having a issue with my tomatoes. the bottom of my tomato looks like its trying to rot or is turning black i have about 5 different types and just about all of them are doing this. the only thing i can think of is i found some of them still had the yellow flower part stuck to the bottom of them...could this be causing this problem?

Thank you for any help!!!

Definitely blossom end rot. The flower remnants have nothing to do with it.

Blossom End Rot ... a growth problem, not a fungus or disease.

1 - Make sure you keep moisture constant. Mulch helps.

2 - If your soil is unusually acid or alkaline, correct it with lime (for acid soil) or Sulfur for alkaline soil

3 - Calcium and magnesium deficiency might be part of the problem. Look up "foliar Feeding" with those two elements.

NOTE: It's unsightly, but you can trim it off and eat the tomatoes.

More than a soil/calcium/moisture , BER is a characteristic of some varieties, specifically Roma and related to it, like San Marzano .....

The thing you can do is to just pitch them soon as you see them. Hopefully the the next round will be BER free.

BER is a characteristic of some varieties, specifically Roma and related to it, like San Marzano .....

If it was a characteristic of the variety itself rather than the growing conditions then it wouldn't be possible to grow any of them without BER and that isn't the case.

While some paste tomatoes show a higher incidence of developing BER, it is due to their structure when the contributing causes of BER exist. When those conditions do not exist paste tomatoes grow just fine.

Boils down to the same thing that I said. So that is a characteristic.
I should have said ONE of the chracteristics ( a = ONE)...... That is also called being "BER PRONE". Again a (=ONE) characteristic.

And we know that BER problem does not continue all season long. That is why you can grow them.

Finally, you better express your own opinion rather than continuing your fault finding mission in my posts.
