I keep a lot of trees in my garage. When I first started out it was not much of a problem as you could just shoe horn the trees in nice and tight with no problems. As the years go by and I had more fully wired trees I found they take up a lot more space in the garage then they did before they were styled/wired. That meant something was going to have to go out side for the winter. I did move a few things outside but decided that was not going to work for most stuff as I am to chicken to take the risk. I have come up with several ideas that seem to be working out good. First I purchased 6 foot plastic tables. I place one plastic table on top of another plastic table. I now get 3 times the floor space then I did before. More trees can stay in the garage. Small to medium size trees go under the tables and on top of the first table. Tall trees go on the top table. I also learned to place a piece of wood under the legs of the table sitting on top of another table. The weight of the trees on the top table will eventually punch (legs) a hole in the top of the table below it. I also came up with an idea of using cinder blocks stacked on top of each other to elevate wired trees above trees that can be shoved together for the winter. This new idea is working out great. Cinder blocks are cheap to buy. A neighbor was throwing out a couple of cheap plastic tables and I rescued them. They are working out ok so far, this is the first year for them. Anything tall will work in place of cinder blocks. Cascade trees go on the top tables.

Here is a gallery showing what I do in the winter:
