How To Add Calcium/nutrients For Established Tree Collards

Question

I read the article on growing tree collards and learned a few things! I’ve been growing them for several years in Santa Rosa and love them. What is the best way to fortify the soil for established tree collards (3+ years old)? I have MaxSea (16-16-16) that I use for my heavy feeders such as squash, artichokes and tomatoes and the tree collard seems to like it as well. Is this a good way to replenish the soil calcium level?
