Q.Rhododendrons
My rhododendron buds did not open last year and are still on the bush. It looks healthy but should I cut them off or will they eventually flower?
If you shrub is still dormant, I would dead head the buds. If your weather has warmed, leave them for now.
Here is some articles on pruning and care information.
