Answer: Your clay containers may well crack or crumble if they freeze, so you want to keep them above 32 degrees Fahrenheit. The tree's roots will also be healthier if the soil temperature is above freezing. You want the tree to rest for the winter so keep it outside until late fall, bring it in for the worst of the weather and take it back outside again in early spring so it can wake up naturally with the season. A maximum winter temperature in this situation would be in the 40 degree range. Keep the soil just barely damp while it is indoors, not bone dry and never wet. Good luck!
