Root Rot

Overwatering

To address root rot in Zebra Haworthia, first, cease watering immediately and allow the soil to dry out completely. If the plant is severely affected, unpot it, remove any mushy, discolored roots with sterile scissors, and let the root system air dry. Repot in fresh, well-draining soil and a pot with adequate drainage holes. Going forward, water only when the soil is completely dry to prevent recurrence.

Leaf Shrivel and Discoloration

Underwatering

To address underwatering in Zebra Haworthia, gradually reintroduce water to the plant. Start by soaking the soil thoroughly until excess water drains out, then allow it to dry slightly between waterings. Establish a consistent watering schedule, adjusting based on the season and the plant's environment. During active growth periods, Zebra Haworthia may need more frequent watering. Always ensure the pot has good drainage to prevent root rot.

Mealybug Infestation

Mealybugs are small, white, soft-bodied insects that feed on the sap of the zebra haworthia, weakening the plant and potentially leading to fungal diseases.

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 pests, effectively killing them without harming the plant. For more severe infestations, applying a neem oil solution or insecticidal soap directly to the plant every 7-10 days for a few cycles can be effective. Ensure the plant is not overwatered and has proper air circulation to prevent future outbreaks.

Leaf tip browning

Excessive direct sunlight

Zebra Haworthia thrives in bright, indirect light. If exposed to too much direct sunlight, the tips of its leaves can start to brown. To remedy this, gradually move your plant to a location where it can receive plenty of light without the harshness of direct sun, such as a north-facing window or a spot that is shaded during the peak sun hours. If the browning is severe, trim the affected areas with sterile scissors.
