Amanda, you can go ahead and deadhead but don't remove any green foliage yet. The bulbs need to continue to photosynthesize so that they have enough energy to bloom next year. You can remove a leaf if it's turned at least half yellow, but it's best to leave them on as long as possible. Certainly remove anything that's totally dead. The flowerless plants may not be much to look at right now but if they produce and store enough energy you will be rewarded with spectacular blooms next year!

some people tie them in a knot and lay them down so they are less rangy looking, or I think even tuck them under the mulch. My goal is to grow them so thick under my fruit trees that the growing plants in the winter/spring reduce grass and other plants and the dying and dead leaves actually mulch the ground. They die off so early that they offer no significant dry season competition to the trees. Has anyone tried this with narcissus/daffodils or any other cool season growing plant? It doesn't rain here in the summer.. thus the above strategy. I'm just getting started and can't afford to buy the bulbs, but scrounge them only when I can, so no results to report yet.
