Root Rot

Overwatering

To address root rot in moth orchids, first, remove the plant from its pot and trim away any black, mushy roots with sterilized scissors. Treat the remaining healthy roots with a fungicide recommended for orchids. Repot the plant in fresh, well-draining orchid mix, ensuring the pot has adequate drainage holes. Going forward, water the orchid only when the top inch of the potting medium is dry, avoiding waterlogging. Ensure good air circulation around the plant to help prevent future occurrences.

Overwatering

To address root rot in moth orchids, first, remove the plant from its pot and trim away any black, mushy roots with sterilized scissors. Then, repot the orchid in fresh, well-draining orchid mix, ensuring the pot has adequate drainage holes. Water sparingly, allowing the top inch of the soil to dry out between waterings. Improve air circulation around the plant to help roots dry more efficiently. Regularly inspect roots for signs of rot and adjust watering habits as necessary.

Mealybugs Infestation

Mealybugs are small, soft-bodied insects covered with a white, waxy substance. They typically feed on the sap of the moth orchid, weakening the plant and potentially leading to fungal infections.

To combat mealybugs, start by isolating the affected plant to prevent the spread to others. Use a cotton swab dipped in rubbing alcohol to dab directly onto the mealybugs, effectively killing them without harming the plant. For severe infestations, applying a neem oil solution or insecticidal soap to the plant every 7-10 days for a few cycles can be effective. Always check the label for orchid safety and test a small area first. Regular monitoring and maintaining good air circulation around your orchids can prevent future outbreaks.

Fungal Leaf Spot

Caused by various fungi, often due to high humidity and poor air circulation around the plant.

To manage fungal leaf spot, start by isolating the affected plant to prevent the spread to others. Remove the infected leaves carefully and dispose of them properly. Improve air circulation around your moth orchid by not overcrowding plants and using a fan if necessary. Lower the humidity around the plant by moving it to a less humid location or using a dehumidifier. As a preventive measure, avoid wetting the leaves when watering. If the infection is severe, consider applying a fungicide specifically designed for orchids, following the manufacturer's instructions closely.
