Hi Daisy. Can you tell us where you are located & what plants you have? It may help in being able to chime in with advice or experience.

Oh my gosh. haha. Of course you need to know that. I live in Minnesota, near the Twin Cities. I have a variety of succulents outside. I will post picture of some of them.

Youre fine as long as it doesnt drop bellow 5 C"(40 F")...

Or if its really wet. Remember that shrublands and wastelands like the ones most succulents grow in have really diurnal temp variation, ranging from 10 to 40 C"....

I usually leave them outside until Oct, sometimes Nov - depends on general weather. Unless temps stay constantly in low 40ties, whole night - not just an hour or two, I leave them there. I would leave some outdoors even longer since many will take around 0*C, but do not want to make moving trip many times...If there are many consecutive rainy days or weeks, I would take them in earlier - as suggested.
