Citrus > Cold Hardy Citrus

New citrus tree in ground

(1/2) > >>

planted a seed grown Meiwa kumquat outside in ground today.  Needed to plant to fit under cicada bag for the 17 year cicadas brood 10

In the specific case of kumquat, do you think being grafted on poncirus makes it more resistant to freeze damage?
What have your observations indicated about this?

I did read that kumquat enters and stays in dormancy much more easily than other citrus species, a protective mechanism against cold damage, so am wondering whether grafting it onto poncirus might be redundant. (Just a thought, I have no idea)

Poncirusguy, you seem to have an eye for kumquats.  How many do you have now?

I have not pushed my kumquats for cold resistance so I don't know either.  I have wondered if Kumquat trees on their own roots would be more cold hardy than grafted to PT/FD because the graft union is more sensitive to cold than a non union.
I have 4 seed grown Meiwa trees and 1 grafted Meiwa on Kuharske citrange.  That graft combination is incompatible and the graft region is dying.  I have 2 seed grown Fukushu kumquat trees 1 grafted Fukushu on C35 and 2 Fukushu on Flying dragon.  1 seedling Fukushu is in ground and the other is in a 30 gallon container.  The C35 Fukushu in in a 30 gallon container and the 2 on flying dragon are in 5 gallon buckets.

I once saw a video on YT that showed a meiwa kumquat planted outside in USA but died from the cold, the owner said he didn't know meiwa was not cold hardy (nor did I) so I would keep those warm in winter just to be safe :)

I have 3 kumquat seedlings, very small ones still though, one I planted in my greenhouse as an experiment and survived temperatures of 0 C outside (so inside greenhouse it's 1 or 2 C) the other 2 are still in a small container and I plan to keep those containerized, because I too don't know how cold resistant non grafted kumquats (regular ones) are.
