Ditto on what Dot says only in my area, one zone cooler (7a), the one gallon pots (8 inch) are safer when placed in the most protected/warmest site you have (as in next to the house on the west/south side where the building will radiate heat back at night). By protected I mean from any northern wind you might have......Also I might warn you about the plants getting too much water during the winter. Too much water can lead to root rot. The roots are dormant, or nearly so, and a ton of water on them does them no good. I place alot of my pots underneath the eaves of the house where winter wet doesn't accumulate as much. Of course then I may have to water by hand at times as they are going dormant, but nothing is easy in life. Unlike Dot I have lost a few over the years; mostly due to too much moisture. Low temperatures (we got down to minus 7 one year, and single digits are not unheard of) being a secondary factor.........Maryl
