I have been having a discussion about this in one of the gardening
groups and am beginning to think it is as much variety sensitivity as
the calcium.

Those large red-green stripey things in that photo are Pink Berkeley
Tie Dyes. They seem particularly sensitive to BER, while those plants
on either side just laugh and point at them. Oh, the Tie Dyes are
sensitive to wilt/blight, too.

I generally plant ~15 varieties, so if conditions are not right for
one or two, I still have some yield. If you are seeking interesting
varieties in tomato plants, try this woman in Lomita, CA. She is
remarkable and well known - so well so that she starts taking next
year's order this upcoming week.

If you want to grow them from seed:

I order a lot of my seed this time of year. Great bargains and the
difference in germination rates is not noticeable.
