Japonicus
Masterpiece
2 options as the soil in the pic looks as though it’s been refreshed and perhaps well draining?
Cinder block on side with holes horizontal, wire each side of pot through a hole in the block
or each side of pot wired to your bench/display area.
2nd option place entire pot into a larger pot and wedge edges between pots reducing movement.
I doubt this tree is in need of repotting, but if it is, after the Summer solstice.
In your environment, are recovery conditions more favorable late Spring or late Summer?
If you get similar to the Santa Anna winds in late Summer, but not Spring, then Spring once
a good flush of growth has occurred, providing proper after care.
3rd option, shorter more wind resistant profiles.
