10 Most Common Reasons behind Orchid Leaf Turning Yellow

For billions of years, the earth is following the cycle of death and rebirth. The plants also serve the same pattern. When orchid leaves become old, they die and new leaves replace them.
As they age, Most of the orchid’s leaves become yellow. Thus, if you have an older plant, you don’t have to be concerned at all.
