Hey, I bought my daughter three of the lilies that look like Stargazer but they are a shorter variety. They planted them almost fully in bloom and now two have completely lost their leaves and blooms and one still has leaves and blooms. They checked them when they started losing the leaves and the spot was sitting in water so we pulled them up and planted them in a better spot. So my question is, what do we do with the ones that lost their leaves? Cut back the stem or leave it until it turns brown and then cut it back? Thanks for your help, Judy
