Your houseplants can be grown outside with care similar to annuals. They want year round warm temps. So, only move them outside when the night temperatures have warmed up. Then at the end of summer you'll want to bring them inside when the night temperatures begin to drop. When you do move them outside, do not put them in direct sunlight, or they'll burn up. Instead find a location the is bright, but shaded.
Not in cold weather. It will kill it. So will direct sunlight on a way hot day. They are grown in greenhouse type situations and would not be hardened off good enough for extreme weather. For whatever that is worth.
I wouldn't think so. Don't know if Young's would know. Look it up.
