I have had issues this year and last with ber on my tomatoes. Every year we have home made compost, and chicken manure rototilled into the garden well before planting, I added fast acting lime. They have not been over or under watered. I tested the soil and the ph is 7.0 , the nitgrogen is high, phosphorous is high. There is plenty of calcium in the soil because there are a years worth of egg shells, we eat a lot and I bake.
I added fast acting gypsum and add some peat moss with the hope that the fast acting gypsum would help the calcium get into the fruit and the peat moss to lower the ph of the soil a bit.
Any thoughts I am frustrated at losing my tomato crop after all the time and effort.
