Brown, as in dry papery brown? That might as well be cut off. It doesn't make the plant any healthier, but it looks a little better. If the plant was blooming, watch for pups. They may emerge even though the main plant was damaged. I've had some recover and pup that I either burned or drowned, so don't give up just yet.

Thanks catkim! Yes they are dry papery brown. I just cut them off and will watch the sun better. I don't think there are any pups.
