No, there is only a very narrow space, otherwise it will intrude onto the walkway. I guess I could set the rear of the mini-shadehouse about 100mm off from the wall, but less would be better. It’s also concrete below, so anything growing would have to be in a pot, which will be itself a challenge and reduce my orchid growing space.
Currently I’m thinking expanded foam sheet insulation - it would have the added advantage of being white and hence reflecting light back onto the rear of the plants.
