Q.How Do You Start An Upside Down Plant?
I have a small patio and can only grow plants in containers.Perhaps upside down does not work in this case?

Plants are not "designed" to grow upside down, and unfortunately, these containers are more for novelty.
Shelves, and small sets of stairs are good for saving space and making the most of a small area for growing, though!
