Any Azelea experts here? I rescued 7 from the garden centre skip 2 years ago... And planted them last August. They went into a newly created bed with lots of ericaceous compost.... They were very pot bound but I loosened off all the roots..... They don't seem to have grown at all... And barely flowered this year.... Considering just digging them up as they were meant to be a mini hedge.... Am I just not being patient enough?
