Can I have some advice on when to remove dead daylily foliage? I'm in zone 6. Some sites say remove it when you begin to see new growth--which I have on many of them. Other sites say wait until any danger of a hard frost is over; not sure when that would be, though our last frost date is May 15, which is a long way off! What has been your experience with this? Thanks very much for your advice!!!
