: I live on Catalina Island. 26 mi off the coast of LA.
: Winters are Highs to 70, Lows to 40. Is that what you
: mean by "Hardiness Zone"?
Your zone sounds like 9 or 10. There are links to "USDA Heartyness zones" (try a search) that will live you an idea of the coldest you can expect.
I'm in zone 5 and can expect winters colder than -20F for winter lows.
As far as what this means to an apple tree in a pot, you shouldn't need to berm your potted tree into the ground for winter protection. In fact you may actually need to supliment its number of hours of cold. Yes people in the tropics actually put northern trees into the fridge (not freezer) to imitate winter dormancy.
