What is the most suitable temperature for coriander growth?

Coriander planting temperature requirements

What is the temperature for coriander to grow?

Coriander is drought-resistant and not afraid of low temperatures. It can generally survive in an environment of about -1°C, but the most suitable temperature for coriander growth is 17-20°C . Generally, coriander is best cultivated in temperate zones. Coriander growth will slow down above 20°C , and seeds are difficult to germinate at temperatures above 25°C.

Coriander is a short-day crop that requires appropriate sunlight. Strong direct sunlight will burn the leaves, causing them to turn purple and become old, and the stems to become hard. It grows well under spring light, but in summer, too strong light will cause bolting, affecting the taste.

Coriander planting time

Coriander can be grown in greenhouses all year round. Under natural conditions, the best time to grow coriander is in March and April in spring and September in autumn, when the climate is mild.

If the temperature is stable, the most suitable temperature for coriander growth is 15-20℃. Coriander is difficult to germinate at a temperature below 15℃ or above 25℃. If it is planted at a temperature above 30℃ without artificial temperature control, there will generally be no harvest.
