I have a few young-ish American sycamore trees (I think at least) and want to make an extended bed around each one approx. 25-30 feet across. I’d like to plant some trees in a ring near the edge of the bed, and since I am renting, the idea of burying the pots came to my mind. I just planted a Tamukeyama (maybe the wrong type but it’s a red/purple lace leaf) in my front yard from a customer removal who wanted it dumped (🙄) and it gave me the itch. That said, I don’t want to be buying $400 trees and leaving them behind when I eventually buy a house in the next 5 or so years. Can I bury the pots and pull the trees periodically to prune roots and upsize as needed? Would it need extra support or staking? For reference, none of the trees would be potted in anything larger than ~25 gallons and I would be pruning roots on anything that isn’t naturally (or modified in some way) under 15 feet to stunt it.
I also have questions about maintaining plants that may not be perfect for your climate. I have fallen in love with the Baby Grand Magnolias (evergreen magnolias in general but the Baby Grand is my cup of tea) and Windmill Palms. I know there are ways to protect them through winter, and since they’d be potted, the garage or a protected corner isn’t out of the question, but does anyone have experience or tips on growing things outside of their typical environment? Thanks for any feedback and advice, it’s much appreciated.
The first picture is the area in question, with the 2 trees. They’ll be limbed up to ~6 feet but otherwise remain untouched. The other pictures are some trees I’ve planted at work. It took me 7 months to finally plant a tree at my own house after planting hundreds all summer and fall. The last one is the maple I just planted that might die because we weren’t super nice digging it up😢.
Last bit of context, the fence is being redone and the grove to the right side of the picture is going to be cleared entirely or cut back significantly. I have no idea what it is but it is 1 gigantic bush or a clump of several of the same bush.
