Why are茉莉 flowers purple?
A comprehensive explanation of why 茉莉 flowers are purple and the reasons related to purple茉莉 flowers and their care methods will be introduced by the editor below.
Anthocyanin degradation: After being exposed to sunlight and high temperatures, the anthocyanins in the flowers are unstable and easily decomposed, causing the flowers to change color.
Soil alkalization: It prefers acidic soil. Soil alkalization affects its growth, and the flowers will also change color. You can water硫酸亚铁 to improve the soil.
Oxidation: When the flowers are about to wilt or just picked, due to oxidation, the flowers will turn from white to purple.
Lack of water and fertilizer: Insufficient water and fertilizer in the cultivation soil will cause the flowers to wither and change color. Water and fertilizer should be supplemented in a timely manner.
I. Anthocyanin degradation
茉莉 flowers contain anthocyanins. When anthocyanins are not very stable, they are easily decomposed. When the flowers first open, the anthocyanins in the flowers are in a complete state. However, when the flowers are exposed to sunlight and high temperatures, the anthocyanins will decompose, causing the flowers to change color.
II. Soil alkalization
茉莉 prefers to grow in acidic soil. If the soil is slightly alkaline, it will affect the normal growth of the plant and cause the flowers to change color. If it is caused by improper management and maintenance, simple treatment is needed. You can pour硫酸亚铁 into the soil to improve it.
III. Oxidation
茉莉 flowers are originally white. Generally, when they are just picked or about to wilt, the color will change, usually from white to purple. After rainfall, both the soil and the air have high humidity. If the flowers get wet, they will also turn purple due to oxidation.
IV. Lack of water and fertilizer
During the茉莉 flowering period, there are certain requirements for water and fertilizer. When there is insufficient water and nutrients in the soil, the flowers on the plant will wither and change color. During maintenance, it is necessary to supplement the required water and nutrients for flowering plants. The soil should be moist but avoid waterlogging. Fertilization can be done once every 2-3 weeks with phosphorus-potassium fertilizer. Before or during flowering, nitrogen fertilizer should be applied less.
