Batavian Lettuce pests — FAQ
What is eating my batavian lettuce?
Batavian lettuce's semi-crisp, slightly thicker leaves still attract the full range of lettuce pests. Aphids colonise leaf undersides and cause leaf curl; slugs shred outer leaves overnight. Its heat tolerance reduces bolting stress but does not deter pests. Scout twice weekly and use row cover as the first line of defence.
