What if the leaves of Jianlan turn yellow?

1. Soil discomfort

The reason: the fleshy root of Jianlan is more developed, which requires better soil permeability. If the soil is sticky, it will affect the root growth and lead to the five major transport nutrients of the root system.

Solution: if the discomfort of the soil leads to the yellowing of the leaves, it is necessary to change the soil in time and choose the special pot culture soil as far as possible, which is generally suitable for air permeability and acidity and alkalinity.

two。 Improper lighting

Reason: Jianlan prefers light, long-term cultivation in the shade will lack chlorophyll, the leaves will turn yellow, but if exposed to strong light, the leaves will be burned, causing the leaves to turn yellow.

Solution: put the plant in a bright place during maintenance and pay attention to proper shading in summer to avoid strong light.
