Default The curse of BER

So I added calcium to the soil, I used fish emulsion fertilizer


I don't think this is the right fertilizer for tomatoes (although it is
what I in my ignorance used), it has too much nitrogen. It's something
like 511.

I found this:

So, the fish fert may not be your cause, but it does not help and may
indeed hurt.

and I
sprayed the leaves with calcium water.

Although some people believe foliar sprays can correct Ca deficiency in
developing fruits, research is very inconclusive on this issue. What is
well known is that Ca only moves in the plant via the xylem and moves
with the transpirational water flow from the roots, up the plant and
into developing leaves. Calcium has no ability to flow from the leaves
via the phloem to the developing fruit. In addition, once fruit has
grown to golf ball size, the waxy outer layer has developed and is
believed to be quite impermeable to water. Therefore, it is recommended
that all Ca supplied to fruiting vegetables be applied via the
irrigation water so as to maximize uptake by roots


And BER set in anyway. No
water stress such as dry roots. I water every day as it is quite warm
and the pots dry fast. This is maddening because I lost so many
tomatoes last year to BER. Just how much more can one do?
