Marcin:
The spring is already here, so the extent of frost damage is becoming visible.

This winter went as follows:
-quite mild weather with a short-term drop to -10°C,
-warming in January with temperatures up to +15°C,
-then a prolonged cool period with ground frozen for at least 2-3 weeks and measured low -13°C.

Such conditions proved easy for poncirus and plants similar to it, but difficult for most other varieties. Most plants, except for poncirus, were protected with mounds made of peat, leaves, soil etc., of varying width and height. This for sure helped them survive, but on the other hand helped less than during the previous winter (with lows approx. -19/-20°C), because of the longer duration of frost.

What survived well: All poncirus (Flying dragon, Kinga1, and others), most Poncirus-like seedlings of citrandarin HRS899O/Q
Survived quite well: Poncirus hybrid from Schleipfer, Twisted Flying dragon hybrid (x yuzu/c4s/Morton)
Considerable damage: Yuzu N4, yuzu Cologne small leaf, citrandarin Forner-Alcaide 5, Ichang papeda IVIA F2, some citrandarin HRS899O/Q hybrid seedlings (Sorfo, Mazurek).
Badly damaged – survived or not?: Ichangstar60, citrumquat Maroon, other citrandarin HRS899O/Q hybrid seedlings (Korela, Lotka).

A positive suprise is the good survival of Schleipfer hybrid. While it's clearly of hybrid character, not a Poncirus-like plant, it survived even above the protecting mound.
The poor performanace of Maroon hybrid is a negative suprise. This is probably due to its poor root condition, and because I replanted it last autumn.

D3, one of the Poncirus-like seedlings of citrandarin HRS899O/Q. It survived well above the mound:


Schleipfer twig surviving above the mound:


Yuzu 'Cologne small leaf' surviving only below the mound:


Nagami x Poncirus 'Maroon' badly damaged this time:


I wrote a longer report on my new website, there you can also find more photos:

Hi Marcin, what variety of Schleipfer do you have? did you get a name or description? (I know, his names are a bit mysterious... :) )

Marcin:
I got its budwood as Citroncirus English Large or Citrandarin English Large / US852. I think the leaves are different from the US852 variants I've seen.

Ilya11:
Hello Marcin,
And what about your PTxYuzu Yolar hybrid? Is it still alive?

Marcin:
Hi Ilya,
Yolar is alive near the ground. It suffered more than its twisted sibling, but I think it will regrow.
