I overwintered well over two dozen tuberous begonias and they came up well after potting in March. But then I made mistake of putting them outdoors this week in the sun two afternoons (most were 4-6 inches high) and some of the plant leaves got burned (not all plants, and on some plants only some leaves). I've moved them to shady area, but: Will the plants with several burnt leaves recover? Should I pinch burnt leaves off of all plants? Or will leaves recover on their own? Anyone have advice?
