Ed, I and others answered you elsewhere where you asked the same question, so let's see what some here have to say about it.

Carolyn, who is also a 5a/b in NYS

Least susceptible to BER - cherry varieties, any of them. Most prone to BER - roma/paste types and heart.

This assumes that you already understand the causes of BER and that BER is primarily growing conditions related, NOT variety related. So technically one can grow any variety or type without any BER issues and many do so.

Yes, thanks. I do understand that BER is due to growing conditions. My problem is that I'm trying to grow large plants in smallish containers, which leads to poor consistancy in available water. I need to either use larger containers or grow smaller plants. Something has to give, because I was using my larger containers to grow other things.

I grow Big Beef every year. Two years ago, my Big Beef tomatoes had a lot of BER but last year there wasn't one tomato that had it. I found my tomatoes growing in-ground were a lot more productive than the ones in pots.

Larger containers is the solution. Even smaller determinate varieties can develop BER when grown in small containers. Shoot, even cherry types can.

It simply isn't possible to maintain consistent soil levels of moisture and nutrients. Using a drip set-up on auto timers helps but takes a great deal of ultra-fine tuning and adjustment.

I think a better topic would be "What can you do to prevent BER". Ami
