Does powdery mildew affect my heirloom herb varieties differently?
I absolutely love growing heirloom herbs that have been passed down through generations, but I’ve been facing some challenges with powdery mildew appearing on a few of them lately. I’m located in Cairo, where the heat and humidity can be pretty intense, and I’m curious if different herb varieties respond differently to powdery mildew. I’ve noticed that my basil seems more affected than my rosemary. Have any of you experienced this in your heirloom plants? Do certain varieties have better resistance? I’d love to hear your insights or recommendations to help me keep these precious plants healthy! 🌿
