Causes and treatments for yellow leaves of purple-leafed barberry

1. Insufficient light

Reason: Purple-leafed barberry likes light and needs to be placed in a place with sufficient light. During its growing period, it must have sufficient light. If the growing environment of purple-leaf barberry lacks sufficient light, its leaves will easily turn yellow.

Measures: Because purple-leaf barberry prefers sunlight, sufficient sunlight and a warm environment will make the purple-leaf barberry grow very fast. Therefore, the purple-leaf barberry needs to be placed in a warm, sunny place.

2. Lack of water

Reason: Berberis vulgaris prefers a moist and cool environment. Therefore, during its growing period, it is necessary to provide sufficient water to promote its growth and keep the soil moist. Although it is drought-resistant, long-term water shortage is not conducive to its growth. Insufficient water will cause its leaves to turn yellow.

Measures: If the yellow leaves are caused by insufficient watering, simply increase watering. When it comes to watering, do not water too much at one time. Just water when you see the soil is dry. Do not let water accumulate in the pot. You should pay special attention to this in winter, and in the hot summer, you can just use spraying water to increase the humidity of the air and soil.

3. Not enough fertilizer

Reason: Purple-leaf barberry needs to be planted in a place with fertile and deep soil. It likes fertilizer and needs sufficient fertilizer during the growing period to provide nutrients for its growth. If there is not enough fertilizer, it will hinder its growth and cause the leaves that have already grown to turn yellow due to lack of nutrients.

Measures: The key time to fertilize purple-leafed barberry is during its growth period. On average, apply decomposed liquid fertilizer once a month. When applying fertilizer, you must control the concentration of the fertilizer and do not apply concentrated fertilizer. If its leaves have turned yellow, you need to apply more flower fertilizer to promote its growth.
