Cold Hardy Citrus Experiment Zone7A NJ

[Nick C]

Been testing out a few cold hardy hybrids and varieties in my zone 7A NJ climate. Looks like the coldest nights have passed and here are the results so far.

Citremon 2 years in ground under hoop house




The rest have been in ground since the summer and only protected on the coldest stretches

Changsha tangerine(?) purchased from ediblelandscaping looks like shit but is still green




Swingle citrumelo looks good




Morton citrange is a little beat up but should bounce back with no problem

nice! are any of them grafted or on their own roots?

I have a taitri, citrumelo, yuzu, poncirus+, and a prague chimera outside but I don't protect them.
All on their own roots except the prague and poncirus+ are on trifoliate. I also have a morton in a pot, not sure if I will plant it out yet.

Yuzu did the worst this year took a lot of damage from 7f. Everything else is fine without damage only defoliation but already have new buds.



Citrumelo:




Taitri:




Prague chimera:


Poncirus+:




Yuzu hasn't put out leaf buds yet:

Looking good. I believe everything is on its own roots. I also have an in-ground yuzu tucked away in my hoop house I forgot to take pictures of. Unfazed by this winter.

Hi, how are your citrus coming back, any interesting updates ?

After last year the changsha and morton bounced back this past summer but definitely got cooked over the recent freeze in my area with lows of 6F

Left the citrumelo unprotected this year and looks like its doing alright.




Yuzu and citremon under hoop house look good

Thanks Nick, very interesting. Means cooked dead or do you think they recover ? Do you have pictures of the changsha and Morton ?

I don't have high expectations of them being alive come the spring. They barely bounced back from last winter. I'll take some pics this week.
