What are some natural ways to deal with plant diseases?

There are several natural methods to treat plant diseases without resorting to harsh chemicals. Firstly, practicing good hygiene is crucial, including regular pruning of infected plant parts and removing and disposing of diseased debris. Additionally, promoting plant health through proper watering and adequate sunlight helps maintain a strong immune system. Using organic fertilizers to supply essential nutrients can also boost plants' resistance to diseases. Beneficial insects like ladybugs and lacewings can be introduced to control pests naturally. Employing companion planting techniques, such as interplanting disease-resistant species or cultivating plants that repel pests, can also be beneficial. Furthermore, applying homemade remedies like neem oil, garlic or chili pepper sprays, and compost tea can help combat certain diseases effectively. Finally, crop rotation can prevent disease buildup in the soil by changing the planting location each season.
