Growing Kiwi from Seed in Boston

Tropical vs. Hardy Kiwi

Store-bought kiwi are almost always the tropical Actinidia deliciosa (Zone 8+). They will not survive frost. Boston winters will kill them outdoors.

Indoor/Cool Garage Strategy

1. Bring indoors before first frost.
2. Keep in a cool (35–45°F), bright garage or unheated room.
3. Water sparingly — just enough to prevent desiccation.
4. Return outdoors after last frost, acclimate gradually.

Long-Term Reality

Tropical kiwi vines grow huge, need a pollinator (male/female), and take 3–7 years to fruit. Consider hardy kiwi (A. arguta, Zone 4–7) for outdoor Boston growing.
