I recently transplanted a shrub that was growing too close to another shrub under a tree. Now, over a week in the Australian summer sun, the leaves slowly became leathery, then started to curl and are now brittle. This is despite regular watering; the ground around the remaining roots is always moist.
There was a lot of root damage getting it out. I didn't prune the top because I wanted to let it focus on new roots rather than new growth on top.
Should I prune back the branches so that the water doesn't have to spread so far? How can I save it otherwise?
