I am looking ahead to next Spring and am wondering if members here know where I can find tree pots. These are for nut trees that will be started from seed; they have tap-roots that go down fast but do not spread much. So, ideally, the pots would be deep, but not wide. Perhaps a 4-inch diameter but 12-inch depth. I noticed some on a YouTube video showing people planting Butternut trees in Ontario: Also attached is a small still image from that video. Pots like this would be wonderful, but I have no idea where to find them. Anybody here know where they can be found in the Lower Mainland?
