Why are the leaves of the thorn plum turning yellow?

Barbary amaranth is the favorite ornamental plant for flower lovers to grow indoors, but many people find that the leaves of Barbary amaranth turn yellow inexplicably during the cultivation period. What is going on? What causes the leaves of Barbary amaranth to turn yellow? There are many reasons for the yellowing of Barbary amaranth leaves. The following editor will analyze them in detail for you.

1. Seasonal reasons

The yellowing of leaves is sometimes due to seasonal reasons, which is the natural law of its growth. Every year in late autumn, the barberry will enter its peak flowering period, but it will soon enter its winter dormancy period. It is normal for its leaves to turn yellow. Even if the leaves fall off after turning yellow, it will not affect its normal growth in the coming year.

2. Overwatering

The yellowing of the leaves of barberry is sometimes caused by excessive watering. Because the flowering period of this plant is in late autumn or early winter, many people will continue to water it in order to make the plant bloom more, which will cause a certain amount of water to accumulate in the flowerpot. This situation will also accelerate the yellowing of the leaves of barberry, causing them to fall off quickly.

3. Insufficient light

When you keep a tiger thorn plant, if you keep it in a cool environment for a long time, its leaves will turn yellow due to lack of sunlight. Without sufficient sunlight, its leaves cannot form chlorophyll and will lose vitality. At this time, you can move it to an environment with sufficient sunlight in time.

4. Temperature is too low

The yellowing of the leaves of barberry is sometimes caused by low temperature, especially after entering winter. If the plant is placed in an environment with too low temperature, its leaves will quickly turn yellow and fall off. To avoid this, it is best to place it in an environment with a temperature above 15 degrees, and water it less, keep the soil in the pot dry, and do not apply fertilizer. This can effectively reduce the yellowing and falling of the leaves of barberry.
