Last year my Jabo hit 27F and lost the main trunk, but there are a couple of other
stems coming up from the ground (suckers, alternate trunks?)
a couple of those survived and it grew bushy again in 1 year
probably becuase the root system wasnt badly damaged.
this year it hit 20F. ... record breaking cold in 50 years at least.
i had put a bucket of hot water under a bedsheet to protect it.
hoping it would stave off a hard freeze.
i had piled up dead leaves/compost too.
when i removed the compost, there were still a couple of green leaves on the plant.
anyway, they can get damaged badly, and im guessing you might loose that main trunk
but, its very possible it will start to re-leaf in a month or 2 from the ground, or sending up suckers etc...
January arctic blast New Orleans
My red just after the frost.
no recent pics, they both look much worse today.
but, i still think they both will come back, even if its just 1 small sucker.
this pic is actually from December
before it hit this year
the damage is from last year.
when the large branches cracked, i lost them totally.
