Pruning common rhododendron — FAQ
When should I prune common rhododendron?
Deadheading and light shaping: immediately after flowering (late spring/early summer). Renovation pruning: late winter to early spring before growth begins.. Deadhead by snapping or cutting spent trusses just above the new growth buds below the flower head. For shaping, cut stems back to a healthy bud or lateral with sharp secateurs. Renovation cuts can go very hard — R. ponticum breaks from old wood reliably.
How often does common rhododendron need pruning?
Deadheading annually after flowering; renovation only as needed every several years. Rhododendron ponticum is a vigorous, spreading evergreen that responds well to hard pruning if it has become overgrown. For routine maintenance, deadhead spent flower trusses after blooming and lightly shape. For renovation of neglected plants, hard pruning back to 30–60 cm from the ground in late winter is effective — it regrows vigorously.
