I have a pair of Eastern Redbud trees (3' tall) that I bought on eBay
this spring as bare-root plants. When I received them, I had neither
time nor place to plant a tree - so I stuck them into a pair of large
plastic pots. They're doing well.

I'm in southern New York, zone 6. Can I get these trees into the
ground this year, or should I try to over-winter them in pots in
the basement?
