Lime Tree Leaves Turning Yellow?
The first thing that comes into your mind when you hear the word “leaves” is what do they mean? Do they refer to the green leaves of a plant or are they something else entirely?
The leaves of a lime tree (Citrus x citrosa) are not actually part of the plant’s body. They’re just there for decoration. When a lime tree loses its leaves, it means that the tree is dying.
It may seem strange to you at first, but if you think about it, all trees have their own set of leaves. You see them on trees around you every day. If a tree dies, then so does everything else living in the area. Trees don’t die because they get old; they die because they stop producing fruit and produce no more foliage.
When a lime tree stops growing new leaves, it turns from green to yellow.
What causes this color change?
The answer lies within the chlorophyll in the leaves. Chlorophyll is one of the main components that gives plants their vibrant colors. Without it, trees would turn completely brown or even go completely black! That’s why some people believe that when a lime tree starts losing its leaves, it’s time to move on and start looking for another place to live.
Green leaves begin to turn yellow when it’s time for the tree to start dying. This isn’t always caused by old age.
