How many days does it take for coriander to sprout?

Coriander, also known as cilantro, is a vegetable and a condiment and is grown in most parts of China. Coriander prefers a cool climate and is not heat-resistant. The suitable temperature for its growth is 15-20℃. So how many days does it take for coriander to sprout? Let’s take a look with the editor below.

1. How many days does it take for coriander to sprout?

Under normal circumstances, coriander will germinate in 7-10 days after germination and sowing. However, the germination time of untreated coriander seeds is uneven. Those that germinate later can be sown in autumn and skip the entire winter, and some can still germinate in the spring of the second year. Coriander seeds germinate faster at suitable temperatures. The suitable temperature for germination is 15-20℃. If the temperature is too low, the germination speed will slow down.

Coriander seedlings grow rapidly under suitable temperatures. Generally speaking, the germination temperature of coriander seeds should be around 20℃. Too high or too low temperature will affect the germination and emergence of seeds. When the temperature exceeds 26℃, coriander grows poorly. However, coriander seedlings can tolerate low temperatures of -6 to -8°C, and mature coriander can tolerate low temperatures of -1 to -3°C.

After sowing, pay attention to shade and moisturize to avoid strong sunlight that causes rapid evaporation of the soil and affects emergence. A layer of straw can be covered to retain moisture, and when 60-70% of the seeds are above the soil, remove the covering immediately to avoid the formation of tall seedlings.

2. Key points for coriander seedling management

1. Soil

Before planting coriander, make sure that the soil's field water holding capacity is around 80%. That is, the soil below 5 cm deep should be able to be squeezed into a ball at chest height and fall apart when it hits the ground. If the soil is too dry or compacted, it will affect seed germination and emergence. The depth of soil covering after sowing will also affect the time of emergence. Generally speaking, it is appropriate to cover the soil with 1-1.5 cm. If it is too deep, it will affect the emergence of seedlings.

2. Suitable temperature

Coriander is a cool-loving crop and cannot tolerate high temperatures. The most suitable growth temperature is 17 to 20℃, and it can withstand temperatures as low as -1 to 3℃. When the temperature is higher than 25℃, coriander seeds will be in a dormant period and germination will be inhibited. Therefore, when sowing, the appropriate sowing time should be selected according to local climatic conditions to avoid sowing in high temperature seasons.

3. Lighting management

After sowing, attention should be paid to shading and moisturizing to avoid strong sunlight that may cause rapid evaporation of soil moisture and affect emergence. You can cover the seeds with a layer of wet grass or cloth to keep them moist. When 60-70% of the seeds are above the soil, remove the covering immediately to prevent the formation of tall seedlings.

4. Water and fertilizer management

Coriander does not have high fertilizer requirements, but proper fertilization can promote its healthy growth. Before sowing, sufficient base fertilizer can be applied, mainly decomposed organic fertilizer . During the growth process, topdressing can be applied in time according to the growth of the plant. At the same time, keep the soil moist, but avoid waterlogging. In hot seasons, watering should be avoided during the noon period to prevent heat damage to the seedlings.

The above is an introduction to how many days it will take for coriander to germinate. Coriander is cold-resistant and can be sown directly through seeds or planted by purchasing seedlings. The seeds usually need to be soaked before sowing to promote germination.
