Answer: Breath of Heaven usually needs only light pruning to keep the plant compact (prune immediately after flowering is finished). Yours doesn't sound as though it's very happy. I'd prune it back a bit after flowering to force growth lower down on the branches and then I'd feed it with an all purpose fertilizer (10-10-10 or 20-20-20) in amounts as recommended on the fertilizer label. Best wishes with your garden!
