How often should bonemeal and gypsum should be added? My phosphorus was a little low on my soil sample. Was thinking about every there months or so add some bonemeal.

Lay off too much bone meal. It will make it too heavy,hard and undesirable. Gypsum is probably okay.

Ok I was just wondering when to add or if I even should.

I would add a dusting like you would in adding lime to a garden and that would be it. Too much bone meal makes the roots like a rock when they dry.
