What is the most suitable growth temperature for carrots (lowest temperature tolerable)

Temperature requirements for growing carrots

Carrots prefer cool weather and cannot tolerate extreme heat, but are relatively resistant to low temperatures. The germination temperature is 20-25°C. Generally, they can be sown when the average temperature is stable at 20°C. Both too high and too low temperatures are detrimental to their growth.

What is the temperature at which carrots grow?

Carrot is a semi-hardy vegetable. Its cold and heat resistance are slightly stronger than radish. It can be sown earlier and harvested later than radish. The germination temperature is 20-25℃ , and the suitable temperature during the seedling stage and the peak leaf growth period is 23-25℃ . The seedlings can withstand short-term low temperatures of around -3℃ and high temperatures of 27-30℃ . The suitable temperature during the fleshy root hypertrophy period is 13-20℃ .

Carrots are long-day crops and require sufficient sunlight during their growth period. If there is insufficient light, it will affect the photosynthesis of the plant, and nutrients for plant growth will not be provided, causing the leaves to become smaller and turn yellow.

Carrot planting time

Carrots are usually sown in summer and autumn and harvested in autumn and winter. Under normal circumstances, they are sown in February in spring and harvested from May to July. Autumn-sown carrots are sown in July and harvested from November to December. In the warm southern regions, they are generally harvested in August and November. In the colder North China region, they are sown in early to mid-July and harvested in early to mid-November. In high-latitude cold regions, the sowing period needs to be earlier.
