(also posted on container gardening)

We would like to plant some trees in large containers at our community garden. We don't need nice pots, they can be second hand. We are not allowed to put trees in the ground, but potted is OK. People occasionally donate trees, so we never buy our own, we just try to find a home for the trees that are donated.

We had gotten 2 fabulous pots (about 40 inches across, 30 inches deep) from a gas station that shut down. We have about a half dozen trees that we would love to pot up, so we need more pots.

Do you have any ideas where I might find such a resource? We'd really like to get them second hand, and the largest we have found at nurseries are too small (and too expensive.)
