Scale on Potted Meyer Lemon: Cosmetic Issue With Organic and Chemical Fixes

Scaly Spots Are Scale Insects

The scrapable, scaly spots on leaves, stems, and fruit are scale insects. They don’t damage the fruit internally but weaken the tree and look unsightly.

Treatment Choices

• Horticultural oil or insecticidal soap for direct contact kill (thorough coverage essential).
• Organic biostimulant: Atomic Grow claims to improve plant health so scales decline.

Watering Tip for Repotted Citrus

Newly potted trees dry from the outside in. Water the outer root ball more frequently until roots colonize the new soil, then water the whole pot evenly.
