General fertilizer is ok, but try one for flowers (low nitrogen?),
and definitely try keeping them on the dry side, with a good throughough
watering to soak the soil then let it dry out again. I find that helps perk
them up a bit. Try not to let them wilt, but if they do, don't panic, they
have remarkable powers of recovery.
