How many days is the growing period of celery? How long does it take for celery to mature?

The growth cycle of celery is about four months , depending on the variety, region, and planting method. In order to harvest smoothly, it is necessary to ensure appropriate temperature, scientific watering and fertilization, and management of pests and diseases.

How many days does celery grow?

The growth cycle of celery is about 4 months. It is sown in early spring in January and February , planted in March and April , and can be harvested in May . Therefore, it is not until May that the harvest can begin, and this period can last until July.

Of course, celery can also be sown around summer, but in summer and autumn, when the temperature is high and the sun is strong, it is recommended to use a shade net for sowing, put it on the market in autumn and winter, and harvest it in May of the following year.

Celery growth stages

1. Germination period

The germination stage of celery refers to the stage from seed germination to cotyledon flattening, that is, the first true leaf appears. Celery seeds are thin, and their ability to break through the soil is weak, so they emerge slowly.

To make the celery sprouts emerge in time and quickly, you need to pay attention to the temperature, humidity, and soil fineness. It usually takes about 7-10 days .

2. Seedling stage

The celery seedling stage refers to the period from the expansion of the first true leaf to the fifth true leaf. The plant is weak, has poor assimilation ability, and grows slowly.

During this period, the vitality is weak, and the seedlings are prone to death due to unfavorable environment and conditions, so it is necessary to pay attention to management. When the seedlings reach 5 leaves, the seedling height is generally 4 to 5 cm, which takes about 45 days .

3. Slow growth period of plants

The slow growth period of celery plants refers to the period from 5 to 8 to 9 true leaves. The plants differentiate a large number of new leaves and new roots, the stems shorten and thicken, the leaf color deepens, and the plant grows slowly.

During this period, there is a special process of growth and development, which is the transformation of the outer leaves into enlarged heart leaves. The development is slow and takes 30 to 40 days .

4. Plant vigorous growth period

The vigorous growth period of celery plants refers to the period from 8 to 9 true leaves to 11 to 12 true leaves. The leaves are fully expanded, the petioles are enlarged, and the growth accounts for about 70 to 80% of the total growth of the celery, which takes 30 to 60 days .

5. Dormant period

The dormant period of celery is from the growth of 11 to 12 true leaves to the harvest at the end of vegetative growth, or it is forced to dormant during the winter due to lower temperatures.

After celery enters its dormant period, it should be harvested in time to avoid aging and a decrease in its edible value.

6. Flower bud differentiation period

The flower bud differentiation period of celery is when the celery growing point has been exposed to low temperature for a certain period of time, the leaf differentiation stops growing, and the growing point differentiates into flower buds.

Generally speaking, when the temperature is below 10℃ and above 5℃ , after more than 10 days of vernalization stage and flower bud differentiation, the plants will bloom under high temperature and long day conditions.

7. Bolting period

The bolting period of celery refers to the stage from flower bud differentiation to bolting and the opening of the first flower. The bolting speed can vary depending on the temperature, sunshine and other conditions.

8. Flowering and fruiting period

The flowering and fruiting period of celery is from the time the celery shoots to the first flower of the entire seed collection and harvesting. Because celery has many branches, the order of flowering and fruiting is different, and the cycle is relatively long, which usually takes 60 to 80 days to complete .
