Troubleshooting
Forellenschluss Lettuce problems — and how to fix them
Forellenschluss Lettuce (Lactuca sativa 'Forellenschluss') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bolting and bitterness
Summer heat and long days push it to flower, turning leaves bitter and milky. Time crops for spring and autumn and use a little shade in warm weather.
Slugs and snails
Holed, slimed leaves in cool damp weather. Hand-pick at dusk, use traps or barriers, and keep the crown clear of damp mulch.
Tipburn
Scorched brown leaf edges from inconsistent moisture and calcium stress during rapid growth. Maintain even soil moisture and steady feeding.
Aphids
Clusters on new growth and inside loose heads suck sap and foul leaves. Rinse off with water, encourage ladybirds, or use insecticidal soap.
