Reviving an Overgrown Boston Fern: Hard Pruning and Repotting

A homeowner inherited a large fern, trimmed old fronds, and found a 6-inch thick layer of completely brown, dried undergrowth. New fronds were emerging. Should they leave it or prune to the ground?

Recommendation

Chop it all the way back. The slight risk of loss is far better than an eternally unsightly plant.

Aftercare

1. Once re-flushing begins, repot into a container at least 4 inches wider.
2. Remove from old pot (may take effort), center in new pot, pack quality potting soil around and slightly over the crown.
3. Water heavily. No additional water needed for a while—this encourages rooting into new soil.
4. After a month, water weekly as needed. Feed lightly with any fertilizer at the lowest recommended rate.
