Overwintering Asparagus Ferns in a Cool Basement: Temperature and Light Requirements

Basement Storage Works If Cool

Asparagus ferns can overwinter in a basement only if temperatures stay in the 40s to low 50s°F. Warm temperatures trigger spindly, weak growth even in darkness.

Ideal Location

An unheated fruit cellar or unheated basement section is perfect. The ferns will go dormant, yellow, and appear dead—that's normal. Cut back in spring, move outside, and they'll rebound by midsummer.
