How to prune wart fern

Any time as dead fronds or overlong rhizomes appear. Snip dead fronds at the point where the stipe meets the rhizome using clean scissors. Trim wandering surface rhizomes back to the pot rim if needed, cutting cleanly just behind a frond node.

As needed — infrequently. Wart Fern (Microsorum scolopendria) is a low-maintenance creeping fern that needs minimal pruning indoors. Remove any fronds that yellow, brown, or die back by cutting cleanly at the rhizome junction. You can trim rhizomes that wander beyond the pot edge, but otherwise let the plant spread naturally — pruning is rarely necessary.
