Can coriander be sown in winter?

Coriander is grown throughout my country. It is suitable for growing in warm climates, but can also tolerate certain low temperatures. Generally speaking, the ideal growth temperature for coriander is 15-20℃, but it can also adapt to low temperatures of -1 to 3 degrees Celsius. So can coriander be sown in winter? Let’s take a look with the editor below.

1. Can coriander be sown in winter?

Coriander can be sown in winter. Coriander likes cool weather and is very cold-resistant, making it very suitable for planting in autumn and winter. When planting coriander in winter, you should choose varieties that are cold-resistant, green early, and bolt late, and the seeds need to be properly treated, such as soaking them in warm water for more than 24 hours, and then germinating them at 20-25 degrees to increase the germination rate.

In addition, when planting coriander in winter, you also need to pay attention to water and fertilizer management and anti-freeze measures for the winter, such as filling with frozen water when the soil freezes at night and melts during the day, and covering the bed surface with hay and other cold-proof wintering materials. Therefore, as long as it is managed properly, coriander can grow smoothly in winter and even be harvested and put on the market before the Spring Festival.

1. Choose the soil

Coriander prefers well-drained soil rich in organic matter, and the pH value is best between 6.0-7.6. Before planting, the soil should be improved by adding well-rotted organic fertilizer to improve the soil's fertility and water retention capacity. At the same time, make sure the soil is deep enough to meet the growth needs of the coriander roots.

2. Sowing time

In winter, the sowing time of coriander is generally selected from mid-October to early November, or adjusted appropriately according to local climatic conditions. The temperature is moderate at this time, which is conducive to seed germination and seedling growth.

3. Processing seeds

Since the shell of coriander seeds is hard, in order to promote germination, you can first use tools such as a rolling pin to crush the seeds into two pieces so that the seeds can absorb water more easily. Soak the crushed seeds in water for about 12 hours to increase the germination rate.

4. Sowing method

It is better to sow coriander by broadcasting. After the seedlings emerge, they can cover the bed surface, reduce water evaporation and lower the surface temperature. Before sowing, first water the sowing ground thoroughly. After all the ground water has penetrated into the ground, evenly sow the soaked or germinated seeds in the sowing bed according to the ridges. After sowing, cover the seeds with a layer of fine soil or wood ash or fine manure about 1 cm thick.

5. Keep warm and moisturize

After sowing, cover the sowing bed with a layer of plastic film or sprinkle a layer of straw to keep warm and moist, so as to promote the germination of coriander seeds as soon as possible.

The above is an introduction to whether coriander can be sown in winter. When sowing coriander in winter, you need to ensure that the temperature is not too low, or take appropriate insulation measures, such as using greenhouses, sheds or covering with insulation materials, to maintain a suitable growth environment.
