We have had some chilly nights. I live in cold country and cannot leave my tender succulents and the cactus out for the winter. They have to come inside. But....most of my tender sucs can survive and do better if I leave them out until the very last minute.
They get to go through their color changes and growth slowdown or the winter growers get their signal it is time to do their thing. It triggers my Jades and Kalanchoes to set bud and flower through the winter.
We have gone down as low as 40 and I have not brought anything indoors except my most tender houseplants but the sucs stay outside until it hits 35 or frost predictions.
So here are some of my fall color. I would like to see your fall colors.
