Right now is a great time. Cut citrus as hard as you like. It'll thank you. I've cut mine pretty hard and laid cow manure underneath. In early september I'll throw out some granular citrus food (yes, chemical) and spray with eco oil.
In mid October I'll do a foliar spray of zinc and manganese, and some eddha iron chelates into the soil.
It's not magic, its just that nature needs a little hand here.
In many cases cutting hard really is required otherwise the citrus gall wasps will stay on the march.
