Overwintering a Fig Tree Indoors in New York

The Challenge of Indoor Fig Dormancy

Fig trees (Ficus carica) require a cold dormant period (30–40°F) to fruit well. A heated New York home (55–70°F) with only 4 hours of sun cannot provide this. The tree has already lost lower leaves and shows weak new growth—signs it’s not truly dormant.

Best Option: Keep It Outside (If Possible)

Most NYC gardeners prune figs hard in fall, wrap stems in burlap and plastic, and leave them outdoors. They tolerate near-zero temperatures. Since it’s mid-winter and the tree has been warm, moving it outside now may shock it. If you have an unheated garage or cold room (40–50°F), use that.

Indoor Care If Outdoor Isn’t Feasible

• Prune back sharply to reduce top growth.
• Keep as cool as possible—cool temps matter more than light.
• Water sparingly, just to keep alive.
• Do not fertilize.
• Move outside in spring after frost danger passes.

Expect little to no fruit next summer due to insufficient chilling. Plan for proper outdoor overwintering next year.
