Thanks David and FarmerDill. Can you offer a brandname of a superphosphate?

Thanks again.

Phosphorus promotes flowers, fruits, and roots. The calcium in bone meal
also promotes roots.

Bone meal must be processed by soil bacteria to release the phosphorus and
calcium. I use bone meal in flower pots and other containers because this
processing is sufficiently slow that I don't worry about roots getting
burned.

In the ground, I generally use superphosphate, making sure there is a
layer of unenriched soil between the plant, bulb, etc and the enriched
soil. In this case, root burn is generally not a problem.
