Bare root trees in pots
I am contemplating ordering a number of bare root trees (white cedar, frasier fir, red pine, white pin, american bittersweet, red-osier dogwood, ninebark, red oak) and planting them in pots until this coming fall. At that time I would plant them on a new lot in northern Wisconsin. The potted plants would be grown in the suburbs of Chicago (z5) and then transplanted in Wisconsin (z3). Since I will not be living in Wisconsin and will not be able to water them after initial planting, I figured pot planting them with frequent water/care this summer would be beneficial. Does this sound like a good plan?
Is there a certain size tree that would be most beneficial to start this way (1-2', 2-3')? What size pots should I use to start the above mentioned plants in? Should I just use regular potting soil or should I use the actual soil I will be planting them in this fall? Thanks again!
