Linda, you addressed your question to Jim W, but I'll jump in here with an observation of my own. Mature, large-bulbed Lycoris have had few problems in my garden. Seedlings and species with small bulbs (such as Lycoris sanguinea) are another story. In my experience, these can be very vulnerable to bulb fly larvae. Why not dig your bulbs and check for damage? Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where the somewhat soapy, peony-like scent of Passiflora incarnata and the sour scent of boxwood fill the house daily. These scents are a bit like cilantro: you have to get used to them; but once you do, it's hard to imagine how you got by without them.
