When should I worry about leaf discoloration in my calendula?
Recently, I've noticed some leaf discoloration in my calendula plants, which are a cherished part of my community garden in Miami. The leaves have started to yellow, and I’m a bit concerned about what might be causing it. I’ve ensured they’re getting adequate sunlight and have been following a regular watering schedule based on the heat. However, I'm unsure if this is just a natural part of their lifecycle or if it indicates a potential issue like nutrient deficiencies or pests. When should I start worrying about this discoloration? What steps can I take to diagnose and address this problem? I'm eager to hear from fellow gardeners who may have experienced something similar and to learn how to best care for my calendula!
