Sow and Plant

Early planting can be done under cover in containers. Continue sowing outside every few weeks for a continous supply.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes

Early sowings are easily attacked by slugs and snails, so may be best in containers. Thin out to give plenty of room for each plant to grow. In hot summer conditions lettuce can bolt (produce flower heads) and becomes tough and a little bitter.

Harvesting

When the heart of the lettuce feels firm pull the whole plant up and cut off the roots. Harvest in the morning when the leaves are cool and full of moisture.
