I'd take them out of their bags and heal them in (dig a slanting trench
and lay the trees so that part of the tops will stick out when the
trench is filled) until the weather settles down. -- Sam Brungardt, St.

2 questions:  

Listers, I have young apple & pear trees out of the ground.  Some
potted, some bare-root in bags.  I could use ideas on whether I should
plant them into the ground ASAP, or keep them stashed in an unheated
shed until this cold snap is past.  Apples look full dormant yet (but I
bet they are awake); pear buds are swollen.

SB, are you sure the infection after the freeze was fireblight?  One
spring after a frosty cold wet bloom season, my trees ended up w/
something like FB but I did some research and decided it was Pseudomonas
blossom-blast.  I never took a sample to a plant pathology lab (it was
alarming only on one old pear tree), but I will probably have more
chances in the future.
