How to grow outdoor coriander over the winter?

Coriander is a vegetable with good cold resistance and is suitable for growing in cool climates. The most suitable growth temperature is 15℃ to 20℃. Coriander does not have strict requirements for light and is a short-day vegetable. So how can outdoor coriander survive the winter? Let’s take a look with the editor below.

1. Choose cold-resistant varieties

When planting coriander, you should choose small-leaf varieties that are cold-resistant, late bolting, fast growing, and suitable for wintering. These varieties usually have strong adaptability and cold resistance and can continue to grow at lower temperatures.

2. Sowing time

Choose the appropriate sowing time according to local climatic conditions and sowing time window. Generally speaking, sowing when the temperature is high and the soil conditions are suitable is conducive to the growth and overwintering of coriander.

3. Soil management

Before sowing, deep plow the land and apply well-rotted farmyard manure to improve soil structure and provide sufficient nutrients. At the same time, keeping the soil moist is conducive to the germination and growth of coriander seeds .

4. Spreading plant ash

Before the cold wave arrives, sprinkle wood ash evenly on the roots of coriander. Wood ash contains more potassium and various trace elements, and has obvious auxiliary thermal insulation effect. You can also mix wood ash with sawdust, wheat bran, rice bran, etc. for better results.

5. Cover with plastic film

Covering the coriander with a layer of plastic film can keep it warm and moist. At the same time, cover the plastic film with a layer of straw or other covering materials to further enhance the thermal insulation effect. When the temperature rises above zero, gradually remove the covering.

6. Water and fertilizer management

Before wintering, water the coriander thoroughly and apply an appropriate amount of organic fertilizer to enhance its cold resistance. At the same time, keep the soil moist during the winter to avoid the soil being too dry or too wet.

7. Small shed protection

If conditions permit, you can also build a small arch shed for coriander and cover it with a layer of cooked film, so that the coriander can grow normally even in the cold winter.

The above is an introduction to how outdoor coriander survives the winter. The weather in winter is cold and changeable, so when planting outdoor coriander, you should pay attention to weather forecasts and meteorological information in a timely manner. Before the cold front arrives, take measures in advance to strengthen the coriander's cold protection and warmth preservation.
