new asparagus crowns and frost?
My asparagus crowns arrived 2 days ago, but the ground is still freezing, soaked and the night temperatures forecast to drop to -6 and barely above freezing in the day time, my books make little mention of how warm the earth/air temperatures should be before planting, could you give me some advice on the best thing to do?
Should I put the crowns into a tub of sand/compost until it warms up or will they survive being planted out when the weather and ground is so cold and horrid?!
I am in London
