Spider Mites on indoor lemon
What's Happening
Lemon trees often drop otherwise healthy-looking green leaves in response to spider mite stress. Mites extract cell sap, and the plant triggers abscission as a defense mechanism to reduce transpiration and pest load. Mites are often mistaken for dirt due to their tiny size and fine webbing.
How to Fix It
- 1
Inspect leaves (especially undersides) for fine webbing and motile specks under magnification.
- 2
Apply diluted neem oil or insecticidal soap every 5-7 days for 3-4 cycles.
- 3
Shower the plant thoroughly to dislodge pests and improve humidity (mites thrive in dry conditions).
- 4
Isolate from other plants to prevent spread.
How to Prevent It
Maintain 50-70% humidity. Perform weekly underside leaf inspections. Wipe leaves monthly with a damp cloth to remove dust and early crawlers.
