Root Rot

Overwatering

To address root rot in Hoya hearts, first, cease watering immediately and allow the soil to dry out. If the plant is severely affected, remove it from its pot, trim away any black, mushy roots, and repot in fresh, well-draining soil. Consider using a pot with better drainage and adjust your watering schedule to ensure the soil has time to dry between waterings. Monitoring the plant's environment for humidity and ensuring good air circulation can also prevent future occurrences.

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 removing any affected leaves carefully to prevent the spread of spores. Improve air circulation around your hoya by not overcrowding plants and using a fan if necessary. Ensure the plant is not sitting in overly moist conditions by allowing the soil to dry out between waterings. If the problem persists, consider applying a fungicide specifically designed for houseplants, following the manufacturer's instructions closely.
