Citrus Leafminer Causing Cupped Leaves: Organic Solution

Serpentine Mines Under the Leaf Surface

The cupping and discoloration on all your potted citrus (Meyer, Palestine lime, grapefruit) is textbook citrus leafminer damage. Look under the leaves for the silvery “railroad tracks” of the moth larvae.

Organic Management

• Leafminers appear in hot weather and disappear with cold.
• Atomic Grow (organic biostimulant) claims to boost plant health and reduce miner pressure.
• Spinosad-based sprays are also effective and relatively benign.

Neem oil (Bon-neem) alone often isn’t enough once miners are inside the leaf.
