Celery likes sunlight, but it does not tolerate strong light and long sunlight. Shade measures should be taken before the celery seedlings emerge, and short sunlight of medium intensity is suitable during the growing period;
How much sun does celery need?
Celery’s optimum growth temperature is 15-20°C (59°F-68°F). It has a high demand for water and should be diligently fertilized when cultivated so that it can grow vigorously.

Celery likes sunlight, but it is shade-tolerant and cannot be exposed to strong sunlight. Before the celery seedlings emerge, it should be covered with a shade net, and it should be careful not to let it receive long sunlight during the growing period, otherwise it will promote its flower bud differentiation and lead to early flowering, so that the quality of celery will be reduced.


Celery also has certain requirements for temperature, it is a hardy vegetable, like to grow in a cool climate, in the celery germination and growth period temperature in 15-20℃(59°F-68°F) the best, the temperature is higher than 20℃(68°F), celery is prone to poor growth, but also easy to produce disease.

Celery is a shallow-rooted vegetable that does not tolerate drought, so it is important to keep the soil slightly moist during the germination and growth period and to have a certain amount of air humidity, otherwise the quality and yield of celery will be reduced.


Celery also has a high demand for nutrients. When planting it, it is necessary to apply a sufficient amount of fertilizer in the soil to improve the fertility of the soil, and to follow the fertilizer at the right time during its growth period, otherwise the lack of nutrients will affect the growth and development of celery, especially the lack of nitrogen fertilizer.


Celery prefers cooler temperatures and adequate light conditions. Seeds germinate faster in light conditions than in dark conditions.

If the plant passes the vernalization stage and is given long sunlight, it will complete its life cycle by flowering and setting seeds. Celery is a low-temperature, long-day plant.

Celery has a light compensation point of 2,000 lux and a light saturation point of 45,000 lux, making it a vegetable with medium light intensity requirements.

Low light is good for the elongation of celery petioles, and strong light is good for the thickening of petioles.

Therefore, celery is suitable for dense planting and more suitable for production in autumn, winter and spring according to local climatic characteristics using protective facilities such as solar greenhouses, greenhouses and arches, and in summer, shade nets can also be used for shading cultivation.


Celery is a long-day crop, and low temperatures and long sunlight can rapidly promote the differentiation of seedling ends into flower buds, with temperature conditions below 10°C (50°F).

After 10 to 12 days to pass the vernalization stage, overwintering celery and early spring planting of celery, both in the early summer of that year under long sunlight conditions celery seeds germinate when they like light, easy to germinate under light conditions, germination is delayed in the dark.

In the early stages of celery reproduction, it is important to have sufficient light to enable the plant to carry out and develop fully, while the nutritional growth period likes medium light intensity.

Therefore, it can be produced in greenhouses, small arches and sunny borders in winter, and shade is required for summer cultivation. Long sunlight can promote the differentiation of flower buds at the seedling end of celery and promote the flowering of shoots.

Short sunshine can delay the flowering process and promote nutritional growth. Therefore, in cultivation, sowing spring celery at the right time, maintaining the right temperature and short sunshine treatment are important management measures to prevent shoots.
