Watch out for

Downy mildew: Remove infected leaves promptly and choose resistant varieties for outdoor crops.

Slugs and snails: Use physical barriers like copper tape or apply iron phosphate pellets to control populations.

Grey mould (Botrytis): Ensure good air circulation and avoid wetting foliage when watering to reduce humidity.

Lettuce root aphid: Improve soil drainage and rotate crops annually to break the pest lifecycle.

Bolting: Sow successively in short rows and use shade cloth during hot spells to delay flowering.
