Meyer Lemon White Parasite: Aphids or Scale—Organic Control

Pest ID

White "parasite" on potted Meyer lemon in CA Central Valley = aphids or scale insects (cottony cushion, whitefly, mealybug). Fruit set good = plant otherwise healthy.

Organic Treatment

• Atomic Grow (expert's top pick): Claimed systemic health boost + pest repellency + bloom/fruit protection.
• Neem Oil: Proven for citrus pests. Spray weekly × 3, cover undersides.
• Insecticidal Soap: Good for aphids/whitefly; less effective on armored scale.
• Horticultural Oil: Smothers scale; dormant or summer weight per label.

Potted Citrus Best Practices

• Pot ≥20 gal, well-draining mix.
• Full sun (6+ hrs), afternoon shade if >95°F.
• Water deep when top 2" dry.
• Citrus fertilizer monthly (Feb–Oct).
• Rain exposure = natural pest wash-off.

Healthy citrus resists pests. Focus on culture first, spot-treat second.
