Deadheading and light shaping: immediately after flowering (late spring/early summer). Renovation pruning: late winter to early spring before growth begins.
How often
Deadheading annually after flowering; renovation only as needed every several years
Technique
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.
