Growing Palm Trees in Maine
Unfortunately, Maine is too cold for palm trees. I would recommend growing palm trees indoors in the container and take them outside during summer. That way you will have palm trees in your garden for a few months out of a year. Some great indoor palms are:
- Areca Palm Tree – Zones 9a – 11 (20 to 25 F)
- Chinese Fan Palm Tree – Zones 8a – 11 (10 to 15 F)
- Kentia Palm Tree – Zones 9b – 11 (25 to 30 F)
- Lady Palm Tree – Zones 8b – 11 (15 to 20 F)
