Q.Other Vegetables, Besides Tomatoes, That Require Calcium
I recently discovered that what caused bottom rot on my tomatoes was the lack of calcium in the soil. Since I’m growing my veggies and herbs in containers, I wondered if there are other veggies and herbs that also need calcium.

All plants need some calcium in the soil, but some are more sensitive to a lack of it than others. Summer squash, peppers, eggplant and tomatoes are the ones that are most known for getting blossom end rot from a lack of calcium.
