Antarctic Tree Fern (Dicksonia) Freeze Damage: Cut and Hope

Damage

Wrapped in hessian, but crowns secreted black hard substance. Same for Rostrata. Owner asks if cutting top off allows regeneration.

Possibility

If roots survived (surface freeze only), they may resprout. Cut to soil level, wait. Consider lifting and repotting in fresh mix for better recovery odds.

Reality

If freeze penetrated root zone, they're gone. But try—ferns can surprise.
