Hello, first time trying to grow fruit trees. I’m in central NC near Raleigh. Just bought a dwarf Pink Lady and a semi dwarf Fuji apple tree from local big box store. Both actively flowering. Pink Lady is about 7/8” diameter, Fuji is about 1-1/4”. I’ve been reading up on pruning but am unclear if i should prune right away, or if it’s too late already this season and i should wait? It also seems like the Fuji has 2 leaders. I believe i should prune 1 off, whenever it is the right time to do so. Is that correct? Lastly my understanding is i should not allow these to try to bear this year & maybe next too. Should i pinch the flowers now, or just wait and pinch any fruitlets that appear?
