Many, many of our over 400 pots freeze solid year on year, and a very tiny number of the plants come to any harm. Those which do are usually ones I was tempted by rather too late in the season and they have not grown strong enough roots to stand the bitter cold. We have trees, shrubs, perennials etc in pots, also many lily bulbs which are currently frozen solid - and they will all do well and come up smiling in Spring or Summer depending on their type. Over 70 hostas freeze regularly, it's the pots I have to be concerned about, not the plants. WE have ebbn gardening here with the frosts for 16 years, and always with huge numbers of pots. Provided they are not too wet when they freeze - and even then as often as not - plants survive being frozen very well. Remember winter 2010 -11? Temperatures down to -17 here in this garden, very little succumbed, a few things were cut hard back, even the potted clematis shrugged it all off. Expect the best, ensure the plants are strong and healthy with very good root systems, and the huge majority will survive unscathed. For the tiny number that don't, well, every dead plant is a new planting opportunity is it not?
