Morton, prague, fast flowering tri grafts on taitri in zone 7a

[vnomonee]

As some might know I've been experimenting with taitri as a rootstock for citrus hybrids since poncirus is too slow for me.

I did a bud graft of morton last year very high on the taitri, it never pushed until now. The bud graft apparently survived 1f/-17.7c polar vortex. My grafts on citrumelo died even though the citrumelo survived.

Congratulation, shows again, how important winter dormancy is for cold hardiness

This is very promising.
My TaiTri seedlings are also among the hardiest. Sacaton Citrumelo seedlings freeze back more often, but the Taitris seedlings withstand the winter almost without damage. this year the foliage is without damage while Sacaton and 5Star seedlings are frozen back right beside them.

Definitely, taitri is the most hardy hybrid that I have. I believe it's due to being deciduous although this is temperature dependant, one year it did not drop all of the leaves, but that was not a typical winter.

I am surprised the swingle citrumelo did not die to the ground from the polar vortex.

Figured I'd post an update on my thread incase someone searches for taitri

Prague on tai tri, might have a couple of flowers?

New grafts to taitri. Don't want to celebrate yet but they look healed up. I've had many grafts rot, temperatures dropped to upper 40s f here. Covered them back up but left the bud exposed and the upper stem on the ichang.
