IN THE END I DID NOT USE THE CHERRY TREE SLEEVE ROLL.ON ALL THE NEW GROWTH WAS BLACKFLY.I CUT SOME OF THE INFESTED BITS OFF,BUT DECIDED THAT IT WAS TOO MUCH OF A JOB. THERE WERE CHERRIES ON SPURS AND BRANCHES.IT WAS TOO MUCH TROUBLE TO CUT THE SLEEVE ROLL.SO I LEFT THE TREE TO NATURE. I PICKED THE CHERRIES WHEN THEY HAD GONE RED INSTEAD OF LEAVING THEM TO FULLY RIPEN[TURN NEARLY BLACK]ON THE TREE.SURPRISINGLY THE CHERRIES WERE FLESHY AND QUITE SWEET.I WAS LUCKY THAT THE BLACKBIRDS LEFT THE TREE ALONE AND DID NOT EAT THE CHERRIES. I MIGHT BUY A CAGE NEXT YEAR.
