Citrus tolerant of 0 degrees

US942 is a good one, I would plant but already have a Bishop citrandarin (seedling of US852) which is said to be decent. I have a couple of grafts of it outside and has been hardy so far. I had a Xie Shan which died to root rot, wanted one to make some crosses with Poncirus+ and possibly get an early and decent citsuma.

Zone 7 can be tough. Are you close to the water? There’s a guy on Reddit who grows an yuzu in the ground outside in Cape May. According to the internet that’s an 8a, and he also said last winter was very mild. Still he just harvested his first fruit.

I’ve heard 842 is good. Not as good as 942, but in the pics I’ve seen the fruit appears larger than 942.

That’s great, I did notice the usda zone map update has Cape May in zone 8a now, up from 7b.

There are some hardier strains of Yuzu that can take lower temps but I’m not sure that those are in the US. My outdoor Yuzu seedling on own root gets damaged below ~9f. It has grown back to about 5 feet now after dying back once completely to the ground level in a polar vortex at ~1f. I am in north east NJ about half an hour from NYC. Houses and apartment buildings around me so there is a def a microclimate here. I wish I could get one of the hardier Yuzu that are available in Europe.

Anyone have experience with 6-15-150 mandarin orange out of the USDA breeding program? Sounds cold hardy and tasty, they consider it a great juicer. USDA 6-15-150 Mandarin Orange - fruitmentorā„¢

That looks fantastic. I think I’ll order some budwood for this spring.

There are some varieties of mandarin on Jeju island that thrive in winters that have temps often between the 40’s and 20’s with consistent cloud cover, and some snow and ice. I think varieties that can ripen there would also be excellent selection for Northern California and western Oregon.

Does anyone know where it is now possible to buy UGA Pink Frost Grapefruit? So far as I know it was licensed only to Georgia Grown Citrus, where it seems to have vanished from their website.

Well I can’t buy it, because it’s exclusive to GA residents. Unless I made the drive for those, not in my plans, I recall seeing them and Madison Citrus had them. But I haven’t looked since I realized I can’t buy UGA citrus.
