Boston Fern leaf drop

Tiny leaflets may keep falling after a dry frond has been rewatered. Look inside the plant for green fiddleheads and check the root ball before adding more water.

Protect the remaining fronds

Rewet dry mix evenly and drain; keep it lightly moist thereafter. Move the plant out of heating airflow or a cold doorway. Remove bare or fully dry fronds at their bases.

If shedding continues despite evenly moist soil, inspect undersides for pests and check whether the crown is firm. A wet, soft crown needs root inspection, while new green fronds show the fern is rebuilding.
