We keep our Sarras in tray during the growth season (spring-early
autumn/fall) but then only water to keep them damp/moist during
dormancy. Same for Droseras except we always water from the top (not
enough trays!). Utrics can be kept in their trays all year. Ours are
grown in a unheated glasshouse, but those in the bog garden survived OK
even though they were rained on often (the water table is about 4"?
from the surface of the bog or less). However, we didn't have any frost
problems this year (greenhouse effect?), so maybe that helped.
>>Perhaps you could pack the pots in compost, which if chosen

>>Keep the root system from freezing seems to be the mesg here.
If freezing conditions are likely, you could try spraying mist all over the
plants. The water freezes all over the plants and actually insulates them
from sub-zero temperatures. At least I've seen it done for fruit trees
on some TV program somewhere. You could also try plastic bottles as domes
or even plastic bags to make mini-greenhouses over your plants.
