Pruning Flax Lilies: Routine Maintenance vs. Rejuvenation Cutting

Regular Deadheading and Leaf Removal

Remove spent flower stalks and any damaged leaves as needed.

Hard Rejuvenation Pruning Every Few Years

Every 4–5 years, cut the entire clump to a few inches above ground in late winter/early spring. This stimulates fresh, vigorous growth.

Best Tools and Timing

Use sharp shears or a hedge trimmer. Late winter is ideal before new growth starts.
