How and when to grow fennel

Fennel Planting Time

Fennel can be sown in spring and autumn. The spring sowing time is from late March to early April, and the harvest is in mid-to-late May. The autumn sowing time is from July to August, and the harvest is in September.

Planting Fennel in Spring

Spring open field early-maturing cultivation is carried out from February to March. Seeding and seedling raising are carried out in greenhouses or small plastic arch sheds. The water broadcasting method is adopted, that is, the seedling bed is first irrigated with water, and after the seeds are evenly sown, they are covered with about 1 cm of fine soil. The sowing amount per mu is 2 to 3 kg.

Growing Fennel in Summer

In summer, fennel is sown directly in the open field from July to August. If sown in high temperature seasons, the seeds are difficult to germinate and need to be soaked at low temperature to accelerate germination. The seeds can be soaked in cold water for 24 hours, the mucus is washed off, and the seeds are placed at 15℃~20℃ for germination. After the radicle is exposed, the seeds should be sown in time.

Planting Fennel in the Fall

Fennel is sown directly in a greenhouse or shed in autumn from October to November. Choose fertile and loose land as the seedbed. The drainage and irrigation should be convenient. Apply 2 to 3 kg of decomposed organic fertilizer, 0.05 kg of potassium sulfate, and 0.02 to 0.3 kg of superphosphate per square meter of the seedbed. Apply the fertilizer evenly into the soil.

Growing Fennel in Winter

Fennel is planted in greenhouses or sheds in winter from October to November. For protected cultivation of fennel in winter, it is advisable to make small high ridges with a ridge spacing of 1 meter and cover the ground with film to prevent water accumulation in the field or increase the ground temperature.

How to grow fennel

1. Sowing method: When sowing fennel, it can be sown in rows or broadcast. Fennel leaves are very small and very suitable for dense planting. The amount per mu is about 3-5 kilograms.

2. Choose the land: Fennel is suitable for planting in places with good drainage and flat terrain. Before planting, the land needs to be turned over, the soil clods need to be broken up, and 3,000 kg of decomposed farmyard manure needs to be applied per mu.

3. Sowing and germination: Fennel needs to be germinated before sowing to make it emerge quickly and evenly. Soak the seeds for 24 hours, scrub the surface material clean, put them in a cool place to dry for a while, then cover them with a wet cloth and germinate at 16-23 degrees. Before sowing, you can water them thoroughly once, then spread them evenly and cover them with a 2 cm layer of fine soil.

4. Field management: Fennel grows slowly, and weeds are easily bred in the field during the seedling period. They need to be pulled out as soon as possible. Water the plants when the soil is dry and wet during the seedling stage. When the plant height is about 10 cm, water it frequently and apply quick-acting nitrogen fertilizer. When the plant height is about 30 cm, it can be harvested.
