Ya wind can be a problem. Last time I had the pots tied down. This time I’m using a Blumat watering system which keep the soil constantly moist, so there is more weight in the pots and they seem to stay put. Now I have the tomato cages in place for support I may tie them anyway.
I’m considering building a make shift poly roof to protect them from the bulk of the fall rain, that should up the anti on the wind problem, but Im worried about getting to the finish line.
