Hi there...we had two nights of cold temps this past week and both nights I covered my one brugmansia that is in the ground. It did ok but some of the outer branches have wilted leaves on the ends of each branch. The newer growth toward the bottom had no damage at all. My question is this: Should I trim off the wilted parts on each branch or leave everything be as is? All my babies I got in my "box of brugs" are all doing great in their little pots and I brought them all inide those two nights. Just prior to this freeze, we were having temps in the 80's!
