In the growing season, plants use the photosynthesis process to convert carbon dioxide, water, and other salts to carbohydrates and conserve energy.
Then in winter months, these are used by the plant roots to supply the nutrients for the plant. Removing the chlorophyll will cause the leaves to become yellow, orange, or red.
The plant is no longer growing; it focuses on survival by going dormant during winter.
Yellow foliage indicates plant problem; that is sometimes serious and sometimes temporary.
In most cases, you can fix the yellow leaves on plants by changing the plant care routine. It is essential to familiarize yourself with plant-specific needs for indoor and outdoor plants.
Any change in the color of leaves indicates nutrients or environmental problems. Remove the damaged leaves to help the plant direct its energy towards new healthy growth.
Properly treating your plant can help you regain the lush green foliage.
