Lettuce is a vegetable loved by many people, with a fairly refreshing taste, rich nutrition, fast growth, and relatively simple cultivation, so many people grow some at home. So when is the best time to plant lettuce? Come take a look with the editor.
Lettuce Planting Time
Lettuce prefers a cool climate, so sowing is generally done in spring and autumn. In spring, it is usually done from February to April, and it can be harvested in May to June, while for autumn sowing, you can start sowing at the end of August and harvest in September to October. However, because different lettuce varieties have different characteristics, when choosing the sowing time, you should first understand the instructions for the lettuce seeds, and then sow according to the local climate.
Lettuce Planting Methods
1. Prepare the seedbed. Loosen and level the soil of the seedbed, apply farmyard manure, and make sure the seedbed soil is fine, level, and nutrient-rich, laying a solid foundation for cultivating strong seedlings.
2. Soak the seeds to promote germination. Carrying out germination treatment before sowing can not only shorten the sprouting time but also increase the germination rate. Put the lettuce seeds into a wet gauze cloth and soak them in clean water. The soaking time is generally about 3-4 hours, and the water temperature can be kept at normal temperature. After soaking, rub them gently, dry off the moisture, then bag them for germination. When most of the seeds have sprouted, they can be sown.
3. Sow and raise seedlings. Before sowing, first water the seedbed thoroughly, and you can also spray some dimethoate solution, which can effectively prevent pest outbreaks. When sowing, use 1 gram of seed per square meter, and after sowing, cover with a layer of fine soil to create a good growing environment for the lettuce. When the seedlings emerge, remove the covering promptly, and at the same time strictly control the temperature; in addition, water is also indispensable.
4. Transplanting. After the seedlings are one month old, the young plants can be transplanted and set out. When transplanting, be careful to stabilize the seedlings, and at the same time water in the furrows to provide the necessary moisture. Transplant reasonably and pay attention to density.
5. Field management. Field management for lettuce consists of daily watering, topdressing, and weeding. Generally, water once every 5-7 days. For topdressing, nitrogen, phosphorus, and other compound fertilizers are suitable; no topdressing is needed in the early stage.
6. Pest and disease control. The main diseases of lettuce are powdery mildew, downy mildew, etc., and the main pest is the whitefly. Therefore, targeted disease control can be carried out by spraying 50% benomyl wettable powder at 1000 times dilution and 40% Fuxing emulsifiable concentrate at 7000 times dilution. For pests, dimethoate solution can be sprayed for control.
