They were planted 2/2013 (as you can see their height in one foto) ...unfortunately i planted all three of them very near eachother and i am afraid too close to the wall...now almost 3 years later you can see how they look like in the other 3 fotos..in the 5th foto you can see in a close zoom their leaves ...
my questions are:
first and most important..must i prune them and how?.i have search in google and didnt find anything..as you can see from the recently pics their branches growing ,lets say in an unusual way..
and second ...i face every summer the same problem with their leaves (suppose you can understand from the pic)...how to help them?
-I appreciate a lot to help me make the best for them...
also...as you can see one of them is much smaller with fewer leaves...is there something i can do also ?
Thanks so much
