Pruning cobra lily — FAQ
When should I prune cobra lily?
Autumn for foliage removal; immediately after flowering for deadheading. Cut the yellowing leaf and flower stalk cleanly at ground level in autumn. To deadhead, remove the spent spathe and developing seed stalk at the base shortly after the flower fades. Avoid disturbing the corm when cutting.
How often does cobra lily need pruning?
Annually, at die-back. Cobra Lily (Arisaema sikokianum) is a deciduous woodland perennial that dies back to a corm each year. It requires minimal pruning. Cut back the yellowing foliage at the base in autumn. Deadhead the spent spathe after flowering if you wish to prevent self-seeding and preserve the plant's energy.
