How many days does it take for coriander to sprout?

Farmers can choose suitable coriander varieties to plant. In order to increase the germination rate, the coriander seeds need to be processed. The shell of coriander seeds is hard, and direct sowing will affect the germination rate and speed. 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?

Temperature is an important factor affecting the germination speed of coriander. At a suitable temperature of 17-20℃, coriander seeds can usually germinate in about 7-10 days. When the temperature is below 10℃, the germination speed of coriander will slow down significantly, and it may take 15-20 days or even longer to germinate. At this time, you can consider taking some insulation measures, such as covering the ground with film, to increase the soil temperature and promote germination.

Coriander seeds need the right amount of moisture to germinate. During the seed germination period, the soil should be kept moist, but do not overwater, otherwise it will affect germination. Cilantro needs to be grown in fertile, well-drained soil. If the soil is too dry or too wet, the germination rate of coriander seeds will be affected.

2. How to plant coriander seeds

1. Seed selection

Choose coriander seeds that are full, fresh and healthy. High-quality seeds are the basis for ensuring a good germination rate.

2. Seed treatment

Because coriander seeds have a hard shell, direct sowing will affect the germination speed and germination rate. Therefore, the seeds need to be properly treated before sowing. You can soak the seeds in warm water for about 20 minutes to 2 days, or soak them in a 1% carbendazim solution for about 20 minutes, then wash them with clean water and let the seeds dry naturally. You can also use physical methods, such as using a rolling pin or cylindrical object such as a wine bottle to gently crush the seed shell, but do not damage the inside of the seed.

3. Site selection and land preparation

Coriander prefers fertile, loose, well-drained sandy soil. Before planting, the soil needs to be deeply plowed and an appropriate amount of farmyard manure or compound fertilizer should be applied to increase the fertility and looseness of the soil. Till the land to remove weeds and rocks and make sure the soil is level.

4. Sowing time

Coriander is generally sown in spring from late March to mid-April and in autumn from late August to mid-September, when the climatic conditions are suitable and conducive to the growth of coriander.

5. Sowing method

It can be sown in rows or broadcast. Row sowing is to dig furrows on the land according to a certain row spacing, spread the seeds evenly in the furrows, and then cover with soil and water; broadcast sowing is to spread the seeds evenly on the land, and then cover with soil and water. Regardless of which method you use, you need to keep the soil moist to facilitate germination and growth of the seeds.

6. Germination and sowing

In order to increase the germination rate and germination speed, you can first place the processed seeds in a moist paper towel or sandy soil to germinate, and keep the temperature at around 25°C. The seeds will germinate after about a week. Then plant the germinated seeds in the soil, water them once, and apply some nitrogen fertilizer appropriately.

The above is an introduction to how many days it will take for coriander to germinate. The most suitable temperature for coriander seeds to germinate is 15-20℃. If the temperature is too high or too low, it will affect the efficiency of germination. Under suitable temperature, coriander seeds that have been germinated and sown will germinate in about 7-10 days.
