Powdery Mildew in Seattle?
Hi All - I am curious to hear back from other Seattle-area tomato gardeners about powdery mildew. I have grown tomatoes in containers for years (about 35 plants - 20 heirloom varieties.) and never had any serious foliar diseases. This year I got hit with powdery mildew big time, largely because I didn't recognize it right away. Did anyone else from the NW have unusual problems with PM this year? I used some organic treatments which contained it, but never did away with it. I wonder if I brought it in with some leaf mulch I collected. Any similar experiences?
