Ficus Leaf Curl: Insect Pests and Fertilizer Mishap

A 6-foot indoor ficus developed shriveled, folded new leaves with yellowing and tiny black bugs in the creases. The owner’s daughter may have watered it with herb fertilizer runoff. The expert advises collecting the insects for ID at a garden center or extension office. If only a few leaves are affected, remove and discard them.

Possible Causes

• Insects: Thrips, aphids, or scale can cause leaf rolling.
• Fertilizer burn: Herb fertilizer may be too strong for ficus.
• Overwatering: Ficus needs little water; soggy soil causes root issues.

Next Steps

1. Get insect ID for targeted treatment.
2. Flush soil with plain water if fertilizer overdose is suspected.
3. Water only when top inch of soil is dry.
4. Repot only if root-bound; larger pots hold more moisture.

Early action can save the tree.
