How to Plant Lettuce for Easy Germination: A Tutorial on Lettuce Seed Soaking and Germination Techniques

Lettuce seeds generally need 10 days to germinate after planting. Unlike other vegetables, they are usually very difficult to germinate under natural conditions, so before sowing, they generally need to be pre-germinated. Below, let's take a look with the editor at lettuce germination and sowing techniques.

Seed Soaking and Germination Methods

The optimal temperature for lettuce seed germination is between 15-25°C. Above 25°C, the seed germination rate drops noticeably, and under natural conditions, seed germination is relatively difficult. Therefore, fresh seeds need to be soaked and germinated in a 15-20°C environment. The spring lettuce seed soaking and germination method is to soak the seeds in 25-30°C warm water for 7-8 hours, remove them and let them dry slightly, then place them at a temperature of 15-20°C to germinate. When 80% of the seeds have sprouted, they can be sown. In summer, low-temperature treatment can be used, such as hanging the seeds in a well to germinate. The seeds can be hung inside a well because the temperature inside a water well is lower and the humidity is high, which can also make them sprout quickly.

Sowing Methods

1. Soil Selection

The soil for growing lettuce is best if it is relatively loose, fertile and well-drained, which can avoid water accumulation affecting seed growth. If you want the seeds to sprout as soon as possible, you can add a little humus to the soil, which is extremely beneficial for seed growth.

2. Sowing

Lettuce seeds are small and light, so when sowing, they need to be mixed with fine sand, stirred evenly in a container, then scattered on the seedbed, and covered with 0.5-1 cm of soil. Under suitable temperature conditions, pre-germinated seeds sprout extremely quickly.

3. Seedling Stage Management

During the seedling stage, lettuce should keep the soil moist and not too dry. When the seedlings grow to 2-3 true leaves, they can be thinned, with a plant spacing of 5-8 cm.

4. Transplanting

Lettuce can be transplanted when it grows to 5-6 true leaves. When transplanting, water thoroughly once, and transplant together with the roots into a large pot. For loose-leaf lettuce, the plant spacing is 15 cm, and 30 cm for heading types. Water thoroughly. In summer, first place it in a cool place to recover, and after about 1 week, once the roots have taken hold, give it normal sunlight.

5. Fertilizing

Lettuce can be fertilized once one week after transplanting, with well-rotted organic fertilizer being best. Two weeks and four weeks after transplanting, apply organic fertilizer once more each time, or a compound fertilizer mainly based on nitrogen, phosphorus and potassium. Stop fertilizing two weeks before harvest.

6. Watering

In high temperatures, lettuce should be watered once in the morning and once in the evening. Small amounts and frequent watering are best, but waterlogging should be avoided. In the early growth stage, it is suitable to control water and just keep the soil moist.
