I've just received my raspberry canes

I've just received my raspberry canes from Marshalls.

I can't put them in just yet because the ground is frozen.

It hasn't snowed yet here.

What shall I do?
are they okay to keep in the bag and watered?
or should i put them in a bucket of soil inside?

can i put them out, in case it snows?

i've got a garage i could put them in - how should i store them?

any help will be gratefully received.

thank you

Don't forget to add a handful of bonemeal to the planting hole when you plant them out.
