I have an avocado tree in a 15 gallon pot, the tree is about 8 feet high. It's too big to bring inside during winter. I live in a townhouse in Yaletown close to False Creek. Anyone have any good ideas on how to ensure it does not die during the winter? I have a similar sized Fig tree next to it in a different pot, and have been told this will survive during Vancouver winters, but I'm not sure about Avocado. Any helpful tips are appreciated!
