How to Manage Pests

Pests in Gardens and Landscapes

Harvesting and storage

It may only take as few as 60 or 70 days for lettuce to mature depending upon the variety and temperature. Head lettuce crops should be harvested as soon as they reach maturity. Leaving them in the garden too long may result in bolting, sunburn, or possibly damage from freezing. Leaf lettuce can be harvested either all at once or over a long period of time by breaking off the outside leaves and allowing the interior leaves to continue to develop. Lettuce has a fairly short shelf life and it should be refrigerated as soon after harvest as possible.
