Marigold sunlight requirements
Calendula light demand theory
Calendula, the genus of herbs, its need for light is quite critical, related to growth and decline.
Calendula likes the sun by nature, and it is a good place where there is abundant light. Where there is sufficient light, the leaves can fully perform photosynthesis to nourish themselves, resulting in bright green and full of vitality, and the stems are tall and strong. In the gardens, in the open place facing south, those who receive full sun, the calendula plants are strong, the flowers are abundant and bright.
However, calendula is not completely afraid of strong light. In the heat of summer, the sun is like fire, the light is too hot, and the strong light is too long, which hinders its growth. At that time, the leaves may be burned, the color turns withered and yellow, and the flowers may wither early. Therefore, during the hot summer, it is advisable to provide them with a little shade to protect them from the scorching sun.
Moderate light is essential for the growth of marigolds. In spring and autumn, the sun is mild, allowing them to be fully immersed in the sun. The daily light can reach 6 to 8 hours, which promotes the differentiation of flower buds and the flowering of flowers. In winter, the sun is short and the light is weak. When you choose to plant it in a place leeward of the sun, try to increase its light to help it survive the winter and preserve its vitality in cold times.
In general, when marigold grows, light is indispensable, so it needs to be adjusted according to time to avoid the harm of strong light and obtain the benefit of light, so that its flowers and leaves can flourish and appear vigorous.
