Yes, but it is far less effective and nutritious than wild ones.

Sweet endive is a name given to it in some regions, but it is actually a bitter vegetable that belongs to the Asteraceae family.

Sweet lettuce, also known as bitter greens, can be grown indoors in winter. The planting method is as follows:

1. Seedling cultivation:

1. Regularly raise seedlings and transplant them . The suitable temperature for germination is 15 to 20°C. Germination will not occur if it is higher than 25°C or lower than 8°C. Germination is required for sowing during high temperatures in summer. Sow the seeds on a well-watered soil surface, cover with soil about 0.5 to 1 cm, keep the soil moist, and germinate in about 1 week. (Germination method: Soak the seeds in water for 5 to 6 hours, dry them slightly, wrap them in a damp cloth, and place them in a cool place for germination. Sow them when about 3/4 of the seeds are white.)

2. Seedlings The soil should be kept moist during the period, and shade should be provided when exposed to the sun in summer. When there are 3 to 4 true leaves, they are planted in pot soil with sufficient base fertilizer. The spacing between plants is about 10 to 15 cm. Water them thoroughly. They can be managed normally after about 1 week.

2. Daily management:

1. Few diseases and insect pests, fast growth, and large amount of fertilizer required. Generally, a decomposed fertilizer mainly composed of nitrogen fertilizer is sprayed once every 7 to 10 days. Organic fertilizer is used to promote leaf growth. Fertilization should be stopped one week before harvesting.

2. It likes coolness and is slightly cold-tolerant but not heat-tolerant. The suitable temperature for leaf growth is 11-18℃. Too high temperature will affect growth or advance flowering.

3. It likes moisture and requires sufficient water during the vigorous growth period. It is usually watered once a day. If necessary, water it early or late to avoid affecting the quality of the leaves.

4. After harvesting, wait for the wound to dry and apply decomposed organic fertilizer once to promote the germination of new leaves. It can be harvested again after a period of time.

3. Harvesting:

Harvesting can begin about one month after planting, or when there are about 15 leaves, usually in the morning, and they will be fully grown, thick and The crisp green leaves can be broken off with your hands.
