i've a grapefruit tree growing in zone 7. does anyone else have one this far north?

obviously it's capable of growing in your climate. the next question is: will it fruit in this climate? they want very hot summers for fruiting, but can tolerate short periods of almost-freezing. does this describe your area these days? global warming might just work to your advantage in this case.

I'm impressed. I wouldn't even try one in zone 8. Although there are folks an hour from me that live in zone 9 and grow grapefruit. I'm in southern Arizona.

If I were lucky enough to have a moldy fruit make a tree, I'd probably try to protect it with some sort of little portable tent/greenhouse--maybe try to put it in a pot I can move.

I'm jealous.

I went to Grenada Spain last winter. They have a zone 7 climate and the mountains are covered with Orange, Lime, Grenadine and Olive Trees. So there are obviously some species of citrus that will grow in zone 7, for some reason in the U.S. we cultivate the types that grow in tropical climates.

It will probably die eventually.
