Hi,

My King Protea, since it was planted from the nursery 2 years ago, has not
flowered once. I planted it with the fertiliser tablet as the nursery
suggested, and have only occasionally thrown some native garden osmocote on
it. It's sitting in slightly acidic sand, covered by mulch. I notice some of
the leaves have 'rust spots' on it and assume that this means an imbalance
of some sort?

Could someone help?
