Last spring I repotted my spider lilies due to overcrowding. I used MiracleGroup Moisture Control Potting Soil. A few weeks later I left for my vacation home and a neighbor watered the plants weekly. When I returned home, I noticed small bubbles had started to form on some of the leaves and over the next few months appeared on more leaves. The winter months are a rest period for these plants, so new leaf growth is minimal. I am hoping to keep these plants going since they were originally from my grandmother and I've had them nearly 30 years.
