How often does river water fern need pruning?
As needed. River Water Fern (Blechnum spicant) needs minimal pruning. Simply remove old, yellowing, or dead fronds at their base as they appear. No shaping or cutting back is required — new fronds emerge from the central crown naturally. Over-pruning can set the plant back, so a light, hands-off approach is best.
