Lactuca sativa
Lettuce (Lactuca sativa) is a popular, leafy, green vegetable. It's easy to grow and a key ingredient in many salads. Crisp, crunchy varieties offer a refreshing, cool taste, while soft, buttery varieties may have a sweeter flavor. Lettuce come in many shapes, sizes, and colors, from soft green Romaine hearts to wavy, ruffled leaves. It is a great source of essential vitamins and minerals such as iron, calcium, magnesium, potassium, and Vitamins A, C, and K. Nowadays, lettuce can be found in grocery stores year-round and is also popular among home-gardeners, due to its easy-to-grow nature.

watering
Lettuce needs plenty of water -- usually about 1-2 inches per week. Water lettuce deeply but infrequently, allowing the soil to dry out slightly between waterings. During hot weather, make sure to check the soil more often and increase the amount of water if necessary. It is important to avoid over-watering, as this can cause the plant's leaves to become limp and yellow. In general, it is best to water lettuce at the base of the plant in the morning, so that water won’t pool and cause damage to its delicate leaves.
sunlight
Lettuce (Lactuca sativa) requires about 6 hours of sunlight each day to grow optimally. Full sun is best for direct-seeded lettuce, especially if the plants are young. To prevent wilting, it is recommended that lettuce be grown during the morning and early afternoon hours. Partial shade can be helpful in very hot and humid climates, but lettuce growth may be stunted and less productive without direct sun exposure. Plants may require less sunlight in the late summer or early fall months if temperatures are warmer than normal. Proper watering and fertilization are also important for healthy lettuce production.
pruning
Lettuce (Lactuca sativa) should generally be pruned 4-6 weeks after its final planting. This is usually when it is around 15-20 cm (6 inches) tall and forming its first true leaves. Pruning should be done either by pinching off the top 2-3 cm (1 inch) of the main shoot or snipping the tips of any side shoots that develop off the main stem. This will encourage the lettuce plant to form a bushy shape, prevent it from bolting (forming flowers prematurely) and ensure it remains compact and productive for a longer period. If more foliage is needed, simply wait 3-4 weeks and prune again. Prune any flowers that have appeared to ensure the plant is directing its energy into leaf production rather than flowering.

FAQ
Should lettuce be harvested early in the morning?
Yes, lettuce should be harvested early in the morning. Harvesting lettuce in the early morning decreases the rate at which the plants lose moisture, resulting in a fresher and crisper head of lettuce. Plus, early morning harvesting helps to avoid the harsh sun of mid-day and the high temperature that can cause lettuce to become wilted or discolored. Therefore, harvesting early in the morning ensures a better quality and longer lasting head of lettuce.
Could lettuce be grown indoors?
Yes, lettuce can be grown indoors. An indoor lettuce garden is a great option for those who have limited outdoor space, are living in a climate that doesn't provide ideal growing conditions, or have inadequate sunlight. Indoor lettuce gardens do best in a sunny spot that receives at least 6 hours of direct sunlight each day. Since lettuce prefers cool temperatures, you can set up indoor lettuce gardens in unheated rooms or even in a spare refrigerator. Use a soil-less medium such as a hydroponic system or a sterile potting soil to ensure that pests and disease don't harm your indoor garden. You can also use grow lights to supplement natural light. Both a mild fertilizer and regular waterings are necessary to ensure that your lettuce plants remain healthy and grow to their full potential.
Should lettuce be planted in rows or clusters?
Lettuce should be planted in rows. Planting in rows ensures that plants are spaced properly, are free from disease, and are easy to access, allowing the gardener to water, prune, and harvest with ease. Planting in clusters would increase the risk of overcrowding, leading to poor air circulation and an increased risk of disease. Additionally, clustering would make it harder to access individual plants.
Should lettuce be planted in the spring or fall?
It depends on the type of lettuce being grown and the climate of the location in which it is planted. In general, most types of lettuce are best planted in the spring when the soil is sufficiently warm, as lettuce prefers temperatures between 45-80°F. Fall can also be a good time to plant lettuce, particularly in areas with moderate winters. Certain types of lettuce, such as winter lettuce, can even be planted in late summer and survive light frosts.
Should lettuce be grown in a greenhouse or outdoors?
The answer to this question depends on where the lettuce is being grown, what type of lettuce and the climate of the area. Generally, lettuce grows best in cool climates which can be provided by a greenhouse or outdoors. In colder climates, lettuce may be better grown in a greenhouse where temperature and humidity can be controlled more easily. In warmer climates where the temperature can fluctuate more, growing outdoors may be a better option. Ultimately, it is up to the grower to decide which option works best for their situation.
Do lettuce plants require a lot of mulch?
Yes, lettuce plants require a lot of mulch. It helps to keep the soil moist, and the lettuce plants cool, since they are heat sensitive. Mulching also helps to reduce weeds, and keep the soil aerated. It would be a good idea to use a 2-3 inch layer of organic mulch, like shredded bark or leaves, to protect the soil and the lettuce plants.
