Fennel can be sown in spring and autumn, and March and April in spring and September in autumn are the best sowing time. The climate in these two periods is warm and suitable, and the light and soil conditions are very suitable for seed germination, which can maximize seed germination. Therefore, it is extremely important to choose the right sowing time.

2. Seed selection

Seeds are extremely important for plants. High-quality seeds can ensure germination rate and make plants grow more vigorously. It is best to choose new seeds picked in the same year for planting fennel, but also mature, full and intact seeds. No seeds with musty smell, diseases and injuries can be used, otherwise the germination rate will be greatly reduced.

3. Land selection and preparation

In fact, fennel is not demanding on the soil, and it is not picky at all. It can be planted in general soil, but it is most suitable to plant in loose and fertile sandy soil with strong irrigation and drainage functions, and the soil pH should be moderate. Before sowing, you should also finish the land, turn the soil at least 35 cm deep, fine the soil, apply sole fertilizer, and then turn it over and level it.

4. Sowing methods

Fennel seeds can be sowed or drilled, and drilling is generally used. The whole land should be ditched at a distance of about 20 cm, and the depth of the ditch is three or four cm, and then the seeds should be evenly spread into the ditch. Cover the soil. After sowing, water it and cover it with a layer of straw or film, so that you can wait for the seeds to germinate.
