Ok, let me give you some background. I have U. Longifolia, U. Tridentata, U. Flaccida and U. Livida growing in a screened in porch. Right now they're getting 3-4 hrs of sun filtered through the screen (no idea how filtered it actually is). Unfortunately, the sun is moving South and the strip of light in my porch is slowly getting smaller because the side of the house is blocking the light. I'm wondering if they can be moved outside to get 6-7 hrs direct sunlight, from 12 PM to 6 PM. Will they survive, or be burned to a crisp?
