What's Eating My Kale?

Kale is the toughest green in the patch and still ends up on everyone's menu. Damage almost always reads as one of five patterns.

Cabbageworms

The signs: Ragged holes mid-leaf with green pellet droppings along the midrib.

What it looks like: Green velvet caterpillars flat against stems and veins; white butterflies overhead are the confession.

What to do: Handpick, fine-net the bed, Bt for heavy pressure.

Flea beetles

The signs: Dozens to hundreds of pinholes, worst on young leaves in spring and early summer.

What it looks like: Tiny shiny beetles that vault off the leaf when disturbed.

What to do: Row cover at planting; mature kale outgrows the peppering.

Cabbage aphids

The signs: Gray waxy crusts along the leaf undersides and crinkled new growth.

What it looks like: Dense powdery-gray colonies, tight in the curl of the leaf.

What to do: Strip the worst leaves, water-blast the rest, soap-spray what remains.

Harlequin bugs

The signs: Pale blotchy stippling that collapses to brown, mainly in hot regions.

What it looks like: Glossy black-and-orange shield bugs with barrel-shaped striped eggs.

What to do: Handpick and egg-crush; pull nearby mustard-family weeds.

Slugs

The signs: Smooth-edged holes low on the plant with morning slime sheen.

What it looks like: Nighttime feeders under mulch and lower leaves.

What to do: Beer traps, board traps, iron phosphate — and water in the morning.

When it's not a pest at all

Lower leaves that yellow evenly and drop while the crown grows on fine are just nitrogen moving to new growth — feed the bed. Purple tinting in cold weather is the variety showing off, not stress.
