We have a large rhodo (~15 feet) that is rather lopsided. It's at the north-west corner of the house. The half looking south and west gets several hours of sun, and has leaves and blooms top to bottom.
The other half (north and east) had several large pine trees in the way blocking any light it could get. Those have been ripped out. There are very few leaves, but there are several big branches. Unfortunately, this is the half you can see when looking at our house.
If we prune the full side, will it encourage more growth to the empty side even though there's less light and less small branches? Should we prune hard, or lightly all over? From the top, the bottom, or everywhere?
We did a light pruning all over on the "full" side and have 4 new whorls of leaves on the "empty" side, but they're all on the same branch.
