Best Powdery Mildew Remedy
What do you think is the best solution to make at home to control powdery mildew. With the June gloom still hanging around here everyday, half of my roses have mildew. I saw a lot of solutions and chose one last month which was water, baking soda, dish soap, and vinegar. After spraying my plants with the stuff all my leaves turned yellow and brown and fell off the bush(I think it was the vinegar since that was the only recipe I caw with the stuff). Sadly half my roses foliage looks horrible and I felt like crying, but now today they have new leaves coming in everywhere. So please let me know what you do that is safe and works. Also, I do I upload pictures? Thanks!
