Prune your Photinia anytime between spring and early fall, with late spring/early summer more acceptable. Red Tips are excellent candidates for rejuvenation pruning. To rejuvenate the plant, cut it all the way back to the ground...to about 6 inches from the ground. It should grow back nicely and you can expect to see 3 to 4 feet of new growth the very first year.
