You don’t have to fight existing garden soil that might be too alkaline.
 
This control is a huge advantage for keeping rhododendrons in pots successfully.
 

3. Mobility Lets You Protect from Harsh Weather

By keeping rhododendrons in pots, you can move them to dappled shade or shelter from strong winds.
