Where I am in the UK we had 90 on my south facing patio last week (not bad for zone
8, OK I admit a lot cooler in the shade) but 3 days ago it started. We have had literally no snow all winter but the wind changed to the North.
Suddenly we are at 30 overnight and about 42 in the day, and that is in the sun. Fortunately the snow is only coming in flurries and not staying, and I know enough about Brit weather not to plant
anything out until at least May. Still I was putting pots of exotics out during the day and bringing them in before dark. They just have to get used to being house plants
But my mulching materials are working overtime with existing stuff that I inherited when I bought the house.
