When should autumn coriander be planted in Northeast China?

Coriander, also known as cilantro, is a vegetable used for flavoring and seasoning. Coriander is extremely cold-resistant and is more suitable for planting in cool seasons. Coriander leaves are thin and tender, very nutritious, and delicious when eaten raw. The growing period of coriander is very short, but the yield is very large. So when should autumn coriander be planted in Northeast China? Let’s take a look below.

1. When should autumn coriander be planted in Northeast China?

The autumn planting time is generally from late July to early August in Northeast China, from late August to early September in North China, and after September south of Jiangsu. The specific planting time depends on the local climate. Coriander is a cool-loving crop that can withstand temperatures as low as minus 2°C. The most suitable temperature for its growth is 15-20°C. When the temperature exceeds 25°C, the growth rate of coriander will slow down significantly. When the temperature exceeds 30°C, coriander will stop growing completely.

2. How to cultivate coriander in high yield?

1. Choose the right seeds

Selecting quality seeds is the first step to successful planting. There are many different varieties of coriander seeds on the market. Some coriander seeds are more resistant to diseases and pests, while others grow faster. It is recommended that you choose high-quality seeds provided by local farms or professional seed companies, which can ensure a high germination rate and better growth.

2. Prepare the soil

Cilantro prefers well-drained soil, so we need to prepare the soil in advance. You can choose loose soil rich in organic matter, preferably one that has been previously applied with decomposed organic fertilizer . Such soil not only provides rich nutrients, but also ensures sufficient breathing of the roots.

3. Reasonable sowing method

When sowing, remember to maintain appropriate spacing. Generally speaking, sowing the seeds at a depth of 1-2 cm and leaving a spacing of 20-25 cm per square meter is conducive to the growth of coriander. After sowing, you can lightly cover the seeds with soil, and then water them a little. Don't water them too much to avoid soaking the seeds.

4. Water in time

Coriander has a high demand for water during the germination stage, so the soil should be kept moist but not too wet. Each time you water, you can use a sprayer to sprinkle water lightly to avoid washing away the soil.

5. Fertilization techniques

When the coriander grows 3-4 true leaves, we can start applying some thin liquid fertilizer. Liquid fertilizer can promote the growth of coriander and increase the color and aroma of the leaves. Remember not to apply too much fertilizer, just dilute it before use.

6. Appropriate lighting

Cilantro prefers sunlight, so make sure your cilantro plants receive at least 4-6 hours of sunlight per day. Coriander can grow well without direct sunlight, but if there is a lack of light, the growth rate of cilantro may be affected.

7. Pay attention to pest and disease control

Although cilantro is relatively resistant to diseases and pests, it may occasionally encounter some minor troubles during its growth. For example, aphids and white butterflies. If you find an infestation, you can use some natural insect repellents, such as pepper water or soapy water to spray. However, you must be cautious when using chemicals, and it is best to choose safe, low-residue products.

8. Harvest time

It takes about 60-75 days from sowing to harvesting autumn coriander. If you take good care of it during the growth process, you can experience the deliciousness of your own home-grown coriander when it’s time to harvest. When the leaves of cilantro become dark green and fragrant, it is the best time to harvest.
