I have it in full sun (as per the care tag) and I'm feeding it Miracid
for azaleas every couple of weeks or after every big rain. I'm
keeping the soil moist but not soggy. Lots of new growth but nothing
resembling flower buds.

Is it merely too early for citrus to blossom here, or must the tree
reach some minimum size, or does citrus come in "boy" and "girl"
varieties and I've maybe got a male?

Ideas?
