What causes the aloe vera leaves to turn red?
Do you know about this? The knowledge of the aloe vera from the Flower Clinic can certainly help you understand why aloe vera leaves turn red. Let's learn about it together!
Some aloe vera enthusiasts have found that the leaves of their aloe plants have turned red and are unsure why. Actually, it's a common phenomenon, similar to the color change in the leaves of succulent plants. So, there's no need to worry. By adjusting the care method appropriately, the leaves of the aloe vera can return to green.
The redness of aloe vera leaves is mainly due to changes in the environment, which is a self-protection mechanism of the aloe vera for self-preservation. Several reasons could cause the leaves to turn red.
1. Excessive drought - If not watered for a long time during the summer, the leaves of the aloe vera will turn red. In this case, watering thoroughly once will help. Thereafter, water regularly when the soil cannot form a clump.
2. Overwatering, leading to root rot, can also cause the leaves to turn red. In this case, dig up the aloe vera, cut off the rotten parts, let it dry in a shaded area slightly, and then replant it in soil with moderate moisture. Refer to the first point.
3. Too much sunlight can cause the leaves to turn red. Although aloe vera enjoys sunlight, too strong light can be harmful. Wild aloe vera in South Africa has slightly red leaf tips, which is due to the strong sunlight in South Africa. The solution is to place the aloe vera in a properly shaded area to avoid long-term direct sunlight.
4. Frost damage in winter can cause the leaves to turn red. During winter, when temperatures are low, keep the aloe vera indoors at night. If it's below 5°C, try to keep it in a well-lit indoor area during the day. Please refer to: If it's a potted aloe vera, the leaves may turn red due to the pot being too small and the roots becoming entangled. Transplanting it into a larger pot in spring or autumn can solve this.
1) The photoperiod affects aloe vera flowering. Different regions have different photoperiods for aloe vera. Generally, aloe vera from tropical and subtropical origins requires a shorter photoperiod and is a short-day plant, usually flowering in autumn. The Curacao aloe vera from South Africa requires a longer photoperiod and is a long-day plant, usually flowering in March to April.
2) The effect of light intensity on aloe vera growth
① The impact of light intensity. Light intensity is associated with altitude, latitude, season, and weather. Generally, the higher the altitude, the stronger the light intensity, and vice versa. The higher the latitude, the weaker the light intensity, and vice versa. In summer, light intensity is stronger, and it weakens in winter. Weather changes are also related to light intensity. If there is more rainfall, light intensity is higher, and it decreases when the weather is dry.
② The effect of light intensity on aloe vera. Aloe vera loves light and grows more vigorously in the sun. With higher light intensity, aloe vera grows more vigorously and faster, and the leaves are bright in color and thick and juicy. With low light intensity, aloe vera looks wilted, the leaves are thin, and the color is relatively dull, so people tend to plant aloe vera in summer. However, it should be noted that during summer, especially at noon, the light intensity may be too high for the aloe vera to bear, and it may get sunburned.
③ Different colors of light have different functions. Light comes in many colors, and different colors have different effects on aloe vera. For example, red and orange light can promote the formation of carbohydrates and are the most absorbed by aloe vera during photosynthesis. There is more red and orange light during scattered sunlight, so aloe vera grows fastest during this time. Blue light is beneficial for protein formation, but aloe vera absorbs it poorly. Short-wave light and blue-violet light are not conducive to the growth of aloe vera stems. Ultraviolet light can promote the synthesis of vitamins and suppress the "excessive growth" of aloe vera. Ultraviolet light is most abundant when the sun is shining directly.
