I have Celeste (5) , Italian Honey (4), LSU Purple (5), Green Ischia (5), MW#1 (2), and Strawberry Verte (5). Age is in parenthesis. I am not familiar with your other varieties. All of these are outside in my PVC structure except my MW#1. MW#1 was hard to root and in a thin pot so I will baby it and allow one more year in the garage. lol My suggestion is to look up those varieties where they are sold and see if there is any mention of cold hardiness in the info section. I check with OTBP and Tinkerbug for information on my new varieties. Once you determined cold hardiness, you can decide what to do with them in the future. Since weather is changing dramatically, I make note of any variety's cold hardiness before adding to my collection. There will be a day when I cannot move them around due to my old age so they must have some cold hardiness.
The rules I follow: those less than 1.5 years old, no matter which type they are, I put in the garage. These were rooted in the spring/summer and I am not sure how cold hardy young trees are no matter if they are cold hardy genetically. They are in really thin 1 gallon or less pots too. The ones that are 1.5 - 2 years old, I cover up and leave outside with some sort of protection. I have read that once a tree reaches 3 years old, they don't need a lot of protection. Knowing that, I still protect all my trees because one never knows how the winter will be. So far we have had 2 polar vortexes this winter which is unusual for the south. Pots are not well insulated against the cold so I would rather over protect than not enough.
For me, age, pot size, and variety are deciding factors in where they end up for winter storage after reaching 2 years old. Of course, the ones you cannot afford to lose or love the most will get special handling. lol
I am sorry I cannot address cold hardiness of the trees you have. Maybe other members can give you more information you need.
