Is onion a shade or sun-loving plant?

Do onions prefer shade or sun?

Onion is a herb that likes sunlight. It is mainly distributed in temperate zones and is a short-day, thermophilic crop.

Its sheaths and leaves are edible, and ample sunlight throughout the growing season will allow it to accumulate more nutrients, thereby improving quality and yield.

Onions in the sun

Onions need a certain amount of sunlight during the growing season, but the requirements for light are not too high. They do not need strong light. Strong light exposure will increase the fiber content of its leaves, and the leaves will gradually age and their use value will decrease. However, if the light is too weak, it will also lead to a decrease in photosynthetic intensity, affecting the nutritional value.

Onions can be exposed to the sun, and they need more sun at normal times, but not too strong light. Onions do not like strong light. In summer, you should pay attention to shading the onions to prevent the leaves from wilting in the sun.

Onion growth habits

Onions prefer a warm and humid growing environment and are suitable for planting in loose, fertile and well-drained soil.

In addition, onion is a drought-tolerant but water-intolerant plant. Under normal circumstances, it does not require watering management. Adequate light is beneficial to its photosynthesis, but it is not adapted to strong light. It is generally grown in loose soil in the courtyard.
