BY all means leave them. I am also in Zone 4 and my hardy trees are frozen
for the winter. They are protected on all sides and top from the wind and
snow load and
critters. Otherwise they will be fine until spring. My set up lets melted
snow and rain
into the area with good drainage in case of warm up. You do not want to
warm them
up...you could start a bud out!!
Keep growing

Subject: [IBC] Frozen pots and watering.


Last summer I built an addition on the north side of my fathers house
to serve as a cold storage basement for vegies. The space size is eight
feet wide by ten feet long by ten feet high. The space is not heated and
has a normal temp between 35 to 40 deg. fh so far this winter, a great
place for my potted trees as it turns out. It has been rather cold over the
past two weeks, (about 10 to 15 daytime and -10 to -20 at night outside) so
the inside temps have been slightly below freezing, between 28 and 30 fh.
While checking on them today I noticed many of them needed watering. After
watering I noticed that on a few of them the water was not soaking in after
a few minutes. After checking a little closer I found that they were
frozen. I decided to warm the space up to about 55 for about two hours to
try and thaw the frozen trees but I still had standing water on a few. The
trees are not potbound just frozen. should I bring the trees in to room
temp and thaw them to allow the watere to settle in or leave them alone?
