It is a very suitable vegetable for cooking. Many people want to grow white jade celery, so when should white jade celery seeds be sown? Let’s take a look below.

1. When should white jade celery seeds be sown?

1. Spring sowing

Suitable areas: Suitable for northern regions or areas with colder climates.

Sowing time: generally sowing from late February to mid-March. The temperature in the north rises slowly in spring, so it is necessary to raise seedlings in advance and then transplant them.

Transplanting time: After seedlings are raised, transplanting should be carried out in late April to early May. It is best to transplant when the temperature is stable at above 10℃.

2. Autumn sowing

Suitable areas: Suitable for the south and areas with warmer climate.

Sowing time: Generally, sowing is carried out from mid-to-late July to early August. Sowing in autumn just avoids the high temperature in summer.

Transplanting time: After raising seedlings, transplanting is carried out from early September to mid-October. The temperature is suitable at this time, which is conducive to the growth of celery.

3. Greenhouse or shed cultivation

With the presence of a greenhouse or shed, off-season cultivation can be carried out and sowing can be done all year round. At this time, sowing is not restricted by season, but attention should be paid to the management of temperature and humidity to ensure a suitable growth environment for celery.

2. How to plant celery

1. Soil selection: Celery prefers loose, fertile, well-drained soil. It is advisable to choose land with moderate soil thickness and rich in organic matter for planting.

2. Sowing time: Celery is suitable for sowing in spring and autumn. In northern regions, celery is generally planted in spring and autumn from mid-April to early May and from mid-August to early September.

3. Sowing method: Celery can be planted by direct seeding or seedling tray sowing. Direct seeding is suitable for large-scale planting, while seedling tray sowing is suitable for small-scale planting.

4. Seed treatment: Before sowing, celery seeds can be disinfected to prevent the occurrence of diseases and pests. Generally, you can soak it in 50℃ water for 30 minutes and then dry it.

5. Planting density: According to soil fertility and the actual situation of farmers, the planting density of celery should be reasonably determined, generally 20,000 to 30,000 plants per mu.

6. Management measures: During the growth period of celery, management work such as weeding, loosening the soil, and topdressing should be done well. Monitor and control pests and diseases in a timely manner to avoid the occurrence of epidemics.

3. Management measures for celery

1. Temperature management: The suitable temperature range for celery growth is 15-25℃. Too high or too low temperature will have an adverse effect on growth. During the high temperatures in summer, it is necessary to take shading measures and maintain good ventilation conditions to prevent celery from being damaged by high temperatures.

2. Light management: Celery likes plenty of sunlight. Insufficient light will cause the plant to grow slowly and the leaves to turn yellow. Therefore, during the planting process, you should choose a place with plenty of sunlight for planting, and pay attention to timely pruning of branches and leaves to maintain good ventilation.

3. Water management: Celery has high requirements for water, especially during the seedling stage and flowering and fruiting stage, the water supply needs to be increased. The soil should be kept moist, but not waterlogged, which can cause disease. At the same time, pay attention to draining stagnant water in time to prevent root hypoxia.

4. Fertilizer management: Celery needs to be fertilized appropriately during its growth period, and topdressing usually begins 3-4 weeks after sowing. Organic fertilizer or compound fertilizer can be used for application, and the amount of fertilizer applied each time depends on the soil fertility and the growth of celery.

4. Related issues in celery planting

1. Pest and disease control: Common pests and diseases of celery include aphids, spot disease, mildew disease, etc. During the celery planting process, regular inspections should be carried out, and when early signs of pests and diseases are found, appropriate prevention and control measures should be taken, such as spraying pesticides , using disease control agents, etc.

2. Increased yield: The yield of celery can be increased through scientific and reasonable planting techniques and management measures. For example, reasonably control the planting density, apply appropriate amount of fertilizer, strengthen disease and pest control, etc.

3. Quality assurance: The quality of celery is closely related to planting techniques and management measures. Scientific and reasonable planting techniques can improve the quality of celery, such as avoiding the use of chemical pesticides, selecting high-quality seedlings, and harvesting in time.

In summary, scientific celery cultivation technology is the key to ensuring its yield and quality. By rationally selecting soil, scientifically sowing, optimizing management measures, and preventing and controlling pests and diseases, the growth rate of celery can be increased, the yield can be increased, and good quality can be maintained.
