Diagnosing the Problem
🌱 Differentiating between Fungal and Bacterial Infections
Identifying the cause of black spots on your Lavender Iris leaves is crucial. Fungal infections typically present as dark, well-defined spots, often accompanied by a fuzzy appearance.
In contrast, bacterial infections manifest as irregular, water-soaked lesions that may produce a foul odor. If you're unsure, consider sending samples to a local extension service for accurate identification.
🌦️ Identifying Environmental Stressors Contributing to Black Spots
Environmental factors can significantly impact the health of your Lavender Iris. First, ensure your soil is well-drained; overwatering can lead to root rot and exacerbate black spots.
Next, assess your light conditions. Lavender Iris thrives in full sun, requiring 6-8 hours of sunlight daily. Lastly, be mindful of temperature fluctuations, as extreme heat or cold can stress your plants and make them more susceptible to disease.
By diagnosing the problem accurately, you can take the necessary steps to restore your Lavender Iris to its vibrant self. This understanding sets the stage for exploring effective treatment options.
