Someone please tell me what I am doing wrong. My famous actress friend left me her dead grandmother's elm bonsai, a cherished object. I was a little nervous then and am more now. She lives in West Hollywood, where the tree is under a vined pergola. I live in cooler, foggier Santa Monica. At first I kept the tree in my bathroom under a skylight where I would remember to water it. It started growing very large leaves. So I put it outside, and we were having foggy days, and it got VERY unhappy. Now we are having a heatwave and I am afraid it may die. It has lost a lot of leaves, they crumpled brown and fell off. It also has little moldy/mildewy spots on its leaves. What can I do? She isn't coming back for another week and I am afraid, deeply afraid. Please help!
