What's going on with the jasmine plant producing purple flowers?
If you want to understand why the jasmine plant produces purple flowers and the analysis of the reasons and solutions for the purple color of the flowers in the topic of flower cultivation, let's learn about it together below.
Anthocyanin bleaching: After being exposed to sunlight and high temperatures, the anthocyanin in the flowers is unstable and easily decomposed, causing the flowers to change color.
Soil alkalization: Jasmine prefers acidic soil. Soil alkalization affects its growth, and the flowers will also change color. You can water硫酸亚铁 (ferrous sulfate) to improve the soil.
Oxidation: When the flowers are about to wither or just picked, due to oxidation, the flowers will turn from white to purple.
Lack of water and fertilizer: If there is an insufficient supply of water and fertilizer in the cultivation soil, the flowers will wither and change color. You should promptly supplement water and fertilizer.
I. Anthocyanin bleaching
The flowers of jasmine contain anthocyanin, which is easily decomposed when it is not very stable. When the flowers first open, the anthocyanin is in a complete state. However, when the flowers are affected by sunlight and high temperatures, the anthocyanin will decompose, causing the flowers to change color.
II. Soil alkalization
Jasmine prefers to grow in acidic soil. If the soil is 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 water硫酸亚铁 (ferrous sulfate) into the soil to improve it.
III. Oxidation
Jasmine flowers are originally white. Generally, when they are just picked or about to wither, 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 blooming period of jasmine, 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, you should promptly supplement the required water and nutrients for the plant to bloom. The soil should be moist but not waterlogged. For fertilizing, you can apply phosphorus and potassium fertilizers every 2-3 weeks. Before or during flowering, apply less nitrogen fertilizer.
The above comprehensive introduction to why jasmine produces purple flowers and the analysis of the reasons and solutions for the purple color of the flowers is hoped to provide green plant enthusiasts with some relevant knowledge about green plants.
