Fennel is grown in many parts of China. It can be sown in spring or autumn. When the climate is suitable, it grows very quickly and can usually be harvested about two months after sowing.
When is the best time to plant fennel?
1. Spring planting
Fennel is typically planted between March and April, with the exact timing depending on local climate conditions. At this time, temperatures gradually rise and soil temperatures stabilize, which is conducive to the germination and growth of fennel seeds . Fennel sown in spring can fully utilize the warmth and rainfall of the season, germinating and growing rapidly, and completing most of its growth cycle before summer arrives. This contributes to improved yield and quality.

2. Autumn planting
Fennel is typically planted in autumn, usually between August and September, though some regions may choose to sow in October. At this time, the temperature is moderate, with a large difference between day and night temperatures, which is conducive to nutrient accumulation and aroma development in fennel. Although autumn-planted fennel has a relatively shorter growing period, its quality is often superior. Furthermore, as temperatures gradually decrease, the occurrence of pests and diseases is relatively less frequent.

When is fennel harvested?
Fennel thrives in sunny, cool-climate environments, tolerating both cold and drought. It can generally be harvested about two months after sowing. Harvesting typically occurs when the plants reach about 30 cm in height. Multiple harvests are possible, similar to harvesting chives . Each harvest involves cutting the plant about 3-4 cm above the ground, followed by fertilization to promote growth. Alternatively, a single harvest can be achieved by uprooting the entire plant.
