I started cultivating lilies about 5 years ago. Every year I put in some new varieties to see how they work out. This year ALL my lilies did poorly, except the ones in pots. Last year I used peat moss on the surface of the gardens. I live in upper Galena Forest and we do get cold and snow. Prior to that I was using Amend and covered with pine needles. In summer the ground dries out very fast, even though I tried using some redwood chips to keep moisture in. I'm debating whether to pick up all the lilies, amend the soil totally and then replant them. Not sure what to do with this. Let me know if you have some suggestions. Thanks!
