Harvest Tips
Rhododendrons are grown for ornamental flowers and foliage, not harvested in traditional sense. Cut flower stems for arrangements by pinching 1/4 inch above a leaf; this encourages branching. Best cut in early morning when fully hydrated. Deadhead spent flowers by grasping the truss base and bending gently to remove the cluster without damaging emerging growth buds below.
