I'm not quite sure what you mean by elevation, But elevation would be only slightly above sea level and plantmaps.com says I live in zone 10b.
We live on the very limit for apples, only golden delicious and some cooking apples seem to do really well, other varieties we have don't produce much and are vulnerable to pests. I hope climate change doesn't skrew my apples over in the future but I think it might.
Yea they fruit great, we haven't harvested any yet but they should be ready soon. (Or now I better check). They are so delicious
