Reg, the microbes in the soil must break the Ca down in order for it to be available to plants. This is not easy to do in containers unless you add microbes into the soil, biota, not only fungi. It's hard to move calcium in soil. If you mixed the shell powder with the soil at preparation time, maybe then they'd be more readily available. I would still be using a calcium supplement if it were me. Eggshells are good, but you need a lot of them in order to make a big difference.
If wrong, I'm sure PJ will correct me. I welcome that, too.
