Planting and Growing Guide for Lettuce (Lactuca sativa)
Description
Lettuce is cool-season crop that grows best in the spring and autumn (fall) in most regions.
Lettuce seedlings will tolerate a light frosts, but they will grow very slowly outdoors in cold weather.
Your first harvest will be sooner if the lettuce and sow in seed trays and kept indoors, planting out
after 4-6 weeks or growth, just after the last frost. Plant in batches every two weeks to ensure a steady
supply over a long growing season.
Lettuce comes in a huge a range of sizes, shapes and colours, all of which are easy to grow.
The main variants are: Leaf lettuce, Cos and Loose-headed types and Firm-headed types.
Choose a variety that does best in your climate and many varieties do poor in hot weather.
Best grown in areas of partial shade as they tend to bolt to flower in hot weather and will
stop producing leaves. Sow closely in rows and use the plants you thin out as leafy greens in salads.
Lettuce have shallow roots and so need a heavy covering of mulch to retain moisture and to control weeds.
Lettuce needs watering daily in hot weather, and during the summer months.
Lettuce is the classic base for most salads, but can be used as a
leafy green for many Asian dishes. There is nothing like fresh lettuce picked straight
from the garden. The firm headed lettuce can be a challenge and so grown several varieties for different uses.
