I can't seem to find a good source of rock phosphate. Would bone meal be a comparable additive for my persimmon and other fruit trees?
Rock phosphate is getting difficult to find. Bonemeal is a great replacement to RP. It also contains phosphorus in plant available forms. It also contains quite a bit of calcium so be wary of using too much if you have alkaline soils with high calcium levels. Blossom end rot may become a problem with some vegetable plants if used in alkaline soils. I don't think it has any adverse conditions with fruit trees.

Why not use both...I do. There are useful things in bone meal not in phosphate and vice versa.

I get my rock phosphate from Amazon...no problems.
