Sandra. I grow mainly tropical plants and I am always asked where to put these plants, in the house and outside. I always say: "Fall/winter - south exposure; spring/summer - east exposure. There is typically not enough light to grow plants successfully with a northern exposure. A west exposure is doable BUT you must protect your plants from this direct sun from noon until 3:00 PM in fall/winter and until 4:00 PM in the spring/summer." As you have found out, a westerly exposure is really rough on most plants and is a killer for the vast majority of tropical plants.
