Causes and treatments of yellow leaves of Tradescantia

1. Too much light

Reason: Tradescantia prefers a semi-shaded growing environment, and when growing indoors, it should be placed in a place with sufficient diffuse light. If exposed to direct sunlight, the leaves of the plant will become dull, yellow and curled.

Solution: If the yellow leaves are caused by direct sunlight, move the plant to a cool and ventilated place in time. After the plant recovers, slowly move it to a place with scattered light for maintenance.

2. Insufficient water and fertilizer

Reason: Tradescantia prefers a humid environment. If you water too little or do not water thoroughly for a long time, the plant will turn yellow due to lack of water. In addition, Tradescantia has high nutrient requirements for growth. If too little fertilizer is applied, the plant will lack nutrients and its leaves will turn yellow.

Solution: When watering is insufficient, add water in time. You can also use a sprinkler to spray around the Tradescantia potted plant to increase the air humidity. When fertilizer is insufficient, add fertilizer in time and control the frequency of fertilization to 1-2 times a month.

3. Root rot

Reason: Whether it is watering or fertilizing, excessive amounts can easily lead to root rot. If there is a problem with the roots, the leaves will not be able to absorb nutrients normally, and will naturally turn yellow.

Treatment: If the yellow leaves are caused by root rot, you need to remove the plant from the pot immediately, cut off the rotten roots, disinfect it, change the soil and replant it.

4. Pests and diseases

Reason: Although Tradescantia is not easily infested with insects and diseases, it may occasionally be harmed by scale insects, causing the leaves of the plant to turn yellow.

Treatment: If scale insects appear, first cut off the infested branches and burn them, then you can use drugs such as cypermethrin and thiamethoxam to spray for prevention and control, or wipe the leaves with white wine, vinegar, salt water, etc. Then place the plant in a ventilated and well-lit place to allow it to recover slowly.
