It takes about three years to re-establish a tree. You must water them correctly during drought during this time. Make sure they were planted at the correct planting depth and that all rope/wire etc has been removed from arond the trunk when planting. No burlap should be left on top of the ball and down the sides for several inches. As for notflowering, they often do not flower till they are established because flowering requires a lot of energy that newly transplanted plants need for rooting.
