How to prune Dracaena fragrans
A corn plant usually needs no pruning. If one cane is weak or too long, shorten that stem to about 6 inches in spring. The removed section can be used as a cutting.
Identify the plant part and the reason for removing it
Choose what to remove
Target a weak cane or stem. RHS describes shortening that stem to about 15 cm rather than routinely cutting the leaf rosette.
Pruning is conditional for Dracaena fragrans: the plant normally needs no pruning, while shortening a weak stem can reduce that stem and provide material for propagation.
Decide whether to prune now or wait
Prune at the right time
RHS places the conditional stem shortening in spring. This is a seasonal recommendation for the indoor profile, not a hard date for every home.
Cut only the selected part
Make one clean cut
Shorten a weak stem to approximately 15 cm. The removed section can be treated as a stem cutting under the separate propagation guidance.
Stop when the pruning goal is met
When pruning will not help
Watch the cut and new growth before pruning again
Care for the plant after pruning
Retain the cut section only if it is intended for propagation. RHS does not prescribe a separate wound-sealing treatment or post-pruning feeding schedule.
