Overwintering Dwarf Agapanthus in Zone 4

Gardener in zone 4 has blooming dwarf agapanthus in 12-inch pot. Cut deadheads; wants to winterize and restart next year.

Winter Care

Fertilize now to strengthen bulbs.
After frost, move pot to coolest above-freezing spot (e.g., unheated porch ~32°F). Dark corner OK.
Water very sparingly — let soil dry between waterings.
Spring: when new growth appears, move to sunny window, resume water/fertilizer.
Move outside when weather warms (May in zone 5) — tolerates light frost.
