Worth - containers are definitely a different beast for BER! One time ever I had BER in the ground and that was when I didn't realize the watering system wasn't working and it had been a good while since my plants had any water in the heat of June.

On the other hand, with containers, avoiding BER is an ongoing task. Calcium nitrate in a liquid feed is very very good at reducing BER in containers. However, for me the most effective thing was shading the container roots. Seems they were heating up quite a bit from sun directly on the container and I believe that was inhibiting uptake of calcium or whatever it is they need to not have BER. Since I started these two things, BER is down to almost 0 in containers.
