When is the best time to plant celery?

Celery is a vegetable rich in various nutrients. It prefers cool climates and has many varieties. There are many vegetable farmers who grow it in large areas of our country. So when is the best time to plant celery?

When is the best time to plant celery?

Celery can be grown all year round. Farmers can choose the appropriate planting time based on the local climate and variety characteristics in order to obtain the most abundant yield and the best quality, thereby improving the economic benefits of planting.

Celery Planting Precautions

1. Seeds need to be germinated before sowing

The outer skin of celery seeds is poorly permeable to water, and direct sowing will result in slow germination and low emergence rate. Especially under high temperature conditions in early autumn, germination is more difficult. Therefore, before sowing, the seeds should be soaked to germinate in order to increase the germination speed and emergence rate.

Germination methods include low-temperature germination and hormone germination. Usually, gibberellin treatment is used, and the seeds are soaked for 12 hours before sowing, which can shorten the emergence time and increase the germination rate. Low temperature germination is carried out in an environment of 15~20℃.

2. Strengthen seedling management

Celery is generally grown by raising seedlings first and then transplanting them. You can choose to grow seedlings in the shade in the open field or use plug trays. During the seedling stage, due to the weak water absorption capacity, the soil needs to be kept moist before emergence to facilitate rapid emergence. After germination, the soil needs to be kept moderately moist because celery has a shallow root system. Spray urea solution once a week to promote seedling growth. Thinning is required twice during the seedling stage. When the seedlings grow to 3 to 4 leaves, select healthy and pest-free seedlings and plant them in the field.

3. Reasonable use of micro-fertilizers and plant growth regulators

During celery cultivation, many farmers use trace element fertilizers and plant growth regulators to improve yield and quality. Trace element fertilizers are mainly boron, and 0.3% borax solution can be sprayed in the middle of growth period. When using plant growth regulators, pay attention to the timing and concentration.

For example, regulators that promote celery growth, such as gibberellin, triacontanol, and brassinolide, can accelerate the growth of celery after use. However, if the water and fertilizer conditions are insufficient, problems such as hollowness and stem cracking may be aggravated. However, excessive use of regulators such as chlormequat and paclobutrazol that inhibit celery bolting and flowering will seriously inhibit celery growth and increase side effects. Therefore, when using, pay attention to the concentration of the regulator to avoid overdose.

The above is an introduction to the time and precautions for planting celery. As long as you master the methods, it will be no problem to achieve a high yield when planting celery.
