I planted sweet william in my flower boxes last year. Of course, being bienniel, it was only leaf rosettes and then the frost came. I only recently found out that container plants don't do well as a general rule over the winter. (I'm a newbie.) This spring, we've had about a week of really mild weather, and on top of all of those dry, brown sweet williams I was about to yank and replace with snapdragons are green tops!! Do I just trim the brown foliage now and wait for my lovely pinks to appear?

I have Sweet William in my garden. It reseeds constantly. I love the fragrance and the butterflies seem to really like it to. Do you have a garden? If you do, I would take the Sweet William out and plant it there. Since you have it in a window box, I would cut back the stalks, which are dead now, and it will send up new shoots. I cut mine back every spring. Hope this helps. Marg
