Common Pests and Diseases
When nurturing your Rex Begonias, it’s essential to stay vigilant against potential pests and diseases. Here’s a guide to help you identify and combat these common afflictions:
Powdery mildew: This fungal disease appears as a white or gray powdery substance on the leaves, hindering their ability to photosynthesize. To prevent it, avoid overwatering, ensure proper ventilation, and spray your plants with a fungicide if necessary.
Botrytis Blight: Another fungal disease, Botrytis Blight, causes brown spots on leaves and stems. It thrives in high humidity and poor ventilation. Promote airflow and humidity control to minimize its impact.
Mealybugs: These insects have a cottony white appearance and suck the sap from leaves, weakening the plant. Use a cotton swab dipped in rubbing alcohol to manually remove them, or spray with insecticidal soap or horticultural oil.
Thrips: These tiny insects damage leaves by feeding on their sap, causing silvery streaks and brown spots. Use systemic insecticides or insecticidal soap to control them.
Whiteflies: These flying insects lay eggs on the undersides of leaves, and their nymphs suck plant sap. Sticky traps, insecticidal soap, or neem oil can help keep them at bay.
Spider mites: These microscopic pests spin webs on the undersides of leaves and feed on their sap. Misting your plants regularly helps deter them, or you can use insecticidal soap or neem oil if needed.
Aphids: These tiny insects are often green or black and can infest stems and leaves, causing yellowing and distortion. Spray with insecticidal soap or horticultural oil to control them.
