Root Rot

Overwatering

To address root rot, first, remove the plant from its pot and trim away any black, mushy roots. Allow the healthy roots to air dry before repotting in fresh, well-draining soil. Ensure the pot has adequate drainage holes. Going forward, water only when the top inch of soil feels dry to the touch, and avoid letting the pot sit in standing water to prevent recurrence.

Shriveling Pearls

Underwatering

To address shriveling pearls due to underwatering, gradually increase watering frequency without overdoing it. Start by soaking the soil thoroughly until water runs out of the drainage holes, then allow it to dry out completely before the next watering. This mimics the natural dry and wet cycles the plant experiences in its native habitat. Monitor the plant's response and adjust accordingly, ensuring a balance between moisture and drainage to promote healthy growth.

Mealybugs Infestation

Mealybugs are small, white, cotton-like pests that feed on the sap of the String of Pearls, weakening the plant and leading to yellowing and leaf drop.

To combat mealybugs, start by isolating the infected plant to prevent the spread to others. Use a cotton swab dipped in alcohol to dab directly onto the pests, effectively killing them without harming the plant. For severe infestations, applying neem oil or insecticidal soap directly to the plant every 7-10 days can help eradicate these pests. Ensure to check hidden areas and under leaves where mealybugs might hide. Regular monitoring and early intervention are key to keeping your String of Pearls healthy.

Sunburn

Excessive direct sunlight

String of pearls plants thrive in bright, indirect light but can be damaged by too much direct sunlight, leading to sunburn. If you notice scorched or brown spots on the pearls, this might be the issue. To remedy this, gradually acclimate your plant to its environment by increasing its exposure to direct sunlight slowly over several weeks. Alternatively, place it in a location where it receives bright, but indirect, light throughout the day. If the plant is already sunburned, trim off the damaged pearls to encourage new growth.
