Why Are Poinsettia Leaves Not Red? Causes and Solutions

Poinsettia is a plant with extremely high ornamental value. Not only are its flowers red, but its leaves can also turn red. However, many people often find that the leaves do not turn red during cultivation. So what should be done when poinsettia leaves do not turn red? Follow the editor to take a look at the causes and solutions for poinsettia leaves not turning red.

1. The Time Has Not Yet Come

A large part of the reason poinsettia leaves are not red is that the time has not yet come. Although its leaves can turn red, they are not red all year round. Generally, its leaves only turn red in autumn. So you need to observe the leaves carefully and wait patiently until its leaves turn red.

2. Improper Watering

Poinsettia likes to grow in moist soil, so it usually needs frequent watering; otherwise the plant will dehydrate, the leaves will lack water, and they will not turn red in autumn. However, it also must not be watered too much, otherwise it will cause root rot in the chicken coop, making it difficult for the root system to absorb nutrients, leading to malnutrition and even causing the death of the poinsettia.

Solution: If too much water has been given, immediately replace the potting soil, cut off all the rotten roots, replant in new soil, place it in the sunlight for cultivation, and master the correct watering method. Generally, in spring and autumn it needs to be watered once every 2-4 days, in summer once a day, and in winter once every 7-10 days, so that the poinsettia leaves turn red in autumn.

3. Lack of Nutrients

A large part of the reason poinsettia leaves are not red is caused by insufficient nutrients. If it is not fertilized in time, it will lead to malnutrition in the poinsettia, making the leaves unable to turn red. However, it also must not be fertilized excessively, otherwise it will cause the poinsettia to grow leggy, making the leaves lose their color, causing the leaves not to turn red, and reducing the ornamental value.

Solution: If the poinsettia has been over-fertilized, you can directly replace it with new soil. Fertilization must be reasonable. In spring, apply organic fertilizer or liquid fertilizer once every half month; in summer, apply liquid fertilizer once every half month; in autumn, do the same as in spring; in winter, no fertilization is needed. This will allow the poinsettia to grow very well.

4. Insufficient Light

Poinsettia is a short-day plant. Under sufficient sunlight, it can help it carry out photosynthesis and promote more vivid flowers. If there is insufficient sunlight, it will cause poor growth and the leaves cannot turn red. However, it also must not be cultivated directly in the sunlight, as this will scorch the leaves and prevent them from turning red.

Solution: If poinsettia leaves are not red due to insufficient light, it needs to be given sufficient sunlight in time. Generally, in spring, summer and autumn, it needs to be placed in a spot with scattered light. When the temperature rises, spray water around it to lower the temperature and increase humidity.
