1. Fennel is generally planted in spring and autumn. Spring planting is mostly between March and April, and autumn planting is between August and September. A warm climate is helpful for seed germination. If planted in summer, high temperatures and strong light will affect the development of seedlings. If the temperature is too low in winter, it will be difficult for the seeds to take root after being planted.

2. Fennel has relatively low requirements for the growing environment, but if you want to increase the yield of fennel, it is best to plant it in sandy soil with fertile soil and good drainage. Apply enough fertilizer before planting fennel. For base fertilizer, it is best to choose fully decomposed farmyard manure. After applying the base fertilizer, the land can be plowed and prepared for planting.

3. Fennel seeds are very small and very light. Direct sowing can easily lead to uneven planting. In order to make the fennel planting more uniform, you can add an appropriate amount of sand to the seeds to make the seeds grow evenly. The fennel is particularly uniform. In order to prevent watering after planting from washing all the seeds together, it is best to water enough before planting, cover the top with a layer of film after spreading the fennel seeds, and spray water in the morning and evening to increase the emergence rate of fennel.
