I know this technique is used often for orchard type trees.
But can any shrub be trained to a wall even with a simple fan shape?
I have plans to make my new property an urban wildlife oasis and want to cram as much as possible onto my lot, haha.
Could one wall train Aesculus pavia for instance? (Interested for hummingbirds and squirrels).
Or Lindera benzoin or even Zanthoxylum americanum for swallowtail host plants?
