BTW quick question. I appears that the one fruit on my surviving Darkest Night (that ultra-black tomato I found). has gotten BER. I'm not planning to remove it (since it is currently the only one there) and, when it is ready, I'll simply cut the bad part out. I assume that is OK. I mean, I'm fairly sure that the seeds in the non-rotted bit will be fine, but I want to double check that any tomato tissue that still looks good is still edible, so I can test in and find out what it actually tastes like (the original fruit went bad before I got around to eating any of it, so the taste is still and unknown.)
I agree. BER is not a disease caused by a virus or fungus. The right amount or calcium does not make it to the fruit. It is possible that your soil may be calcium deficit, but that is usually not the problem. If your soil has some clay in it there is probably enough calcium. A good soils analysis will tell you. It should not hurt to add some calcium but that may not be the fix you need.I think you're all good to collect seeds from your BER affected tomato; it is caused by a calcium deficiency (often brought on by a dry spell where water is unable to deliver the calcium) so no worries about pathogens. The seed will not be compromised because of BER.
The problem is usually that it is dry so there is not enough water to carry sufficient calcium to the fruit. I've read that too much water can cause the same problem but I'd think if it is that wet you probably have other issues. If too dry is the issue the answer is to keep the soil damp enough. Try to avoid swings between damp and dry, If it rains you can't do much about wet, hopefully your soil drains. Mulch is often a big help as it slows evaporation and helps retain moisture.
The gut reaction to BER is to throw a lot of calcium at the problem. That's generally not the best solution, moisture control usually is. But that depends some on soil type. Sand does not hold moisture and will not have the minerals clay does so if your soil is mostly sand you may have a double whammy.
