Daphne Odora sick
I've got a Daphne Odora that has been growing lustily in its raised bed in Seattle for 10 years. It started as a one-gallon pot, and is now about 6'x8' and 3' high. in the past week I've noticed severe browning of leaves, mostly older leaves, but now new growth is starting to get it. The center of the leaf first develops a circular yellowish spot, which then turns brown and spreads until the entire leaf, except the margins has become a dull brown. The brown leaves are scattered all over the plant, and it's getting worse. Any suggestions on saving this venerable and loved plant will be appreciated!
