Thoughts on Neptune's Harvest Crab Shells for container?

cheebamaster · May 1, 2015

I keep running into a problem where I don't know what the best solution for adding organic calcium to my containers is. I've used gypsum on some, and am planning on getting a bag of neptunes harvest crab shells and adding a cup or so to the soil mix. Will this break down in time to avoid BER? I noticed my Early Girl tomato was developing BER on a few of the tomatoes and they were containers in which I added gypsum, so now I'm wondering if the gypsum hasn't broken down properly yet.

What have you found to be the best way to calcify soil in containers?
