Last spring I took my collection of pings outside, in full sunshine. They didn't react, since I had them in bright shade for a week. However, full sunshine also meant full exposure to the other elements, particularly rain. We had an all day rain and the tray they were in got flooded. That resulted in the scattering of plants and leaves, as well as killing some plants within a week or several weeks later or totally stunting their growth, as well as killing the 2 flowers that were in existence at the time.
My question is if I could find a location, like under or at the edge of the porch, where they would get less than full sunshine but protected from rain, would that work? Would a few hours of sunshine, with lots of bright shade be enough for giving them color and growth? It's either that or a window sill or maybe under a shoplite.
