wintered-over plant wilting
I have a brugmansia that was afflicted with whiteflies last summer. I kept it in the basement all winter, barely moist, so it was just bare stems when I brought it up a while ago. I put it into the light, and it began two grow several new shoots, but the soil of it and other plants in the house seems to be infested with flea beetles - this may be irrelevant, not sure.
In any event the new shoots are starting to wilt at the end, and turn gray. Any suggestions as to what I might be doing wrong, and what to do about it? I know little about this plant but would hate to lose it! Thanks in advance!!!
