We have to keep lime-hating plants in containers here. We have a
Pieris which has had a spell of minimal attention, which is now
looking very leggy. It is about 3 to 4 feet high and wide and in a
large plastic pot. Is it a practical proposition to rejuvenate it by
pruning and feeding, or is it unlikely to respond?

There is already much more that needs doing in this garden to try to
get/keep order than I can comfortably cope with, so if it is not a
good bet, I shall clear it away and get another.
