This winter with some freeze days and temperatures down to -13 ° C was a good
test for my citrus hybrid seedlings (seeds from Ilya), two years old and first or second winter unprotected in ground.
two N1tri seedlings, the left with heavy bark crack - I think he won' t survive, the right one seems without
any damage. Deepest low in this place have been -10 to -11 ° C. Thermometer at the wall behind showed
-10,2 ° C. A third seedling of this lot defoliated like Poncirus and seems also very well, not on the picture.
Ivia seedling (seeds from Flo) was already last year in ground, last year with deepest temperature
-8 to -9 ° C he already lost 50% of the main trunk ( though passive protected).
This winter unprotected with deepest low -12 ° C seems he got killed.
Ichangensis SRA 241 seedling (seed from Ilya), also 2. winter in ground, looks pretty good, no damage to be seen.
This winter unprotected with deepest low also -12 ° C.
The seeds seem to be from open pollination, due to the mono-, bi - and trifoliate leaves.
