We transplanted a 15-foot Pieris over the fence to save it from destruction last summer. It didn't seem to go through transplant shock, but is now ailing after a paltry bloom and no red coloration this spring or summer. Wondering if this is due to the big shift in light levels due to the construction of a monster house that cuts off western sun. The Enkianthus next to it is happily green, but also not showing much bloom and isn't gaining any height. It's about 5 feet tall, so should be getting much larger. Any thoughts on what can be done, given moving the new house next door is not an option?
