How to Grow
Water lettuce frequently and hoe between plants regularly to prevent weeds from establishing. Dry weather may cause heads of lettuce plants to bolt so watering is particularly critical during the 2 weeks before harvesting. A thick mulch applied around the plants will help to retain moisture in the soil. Harvest lettuce when required by pulling up the entire plant before trimming off the stem with a knife.
