What should I do if the leaves of bellflower turn yellow?

This plant, also known as "China", is a herb. If you look closely, you will find that its name is closely related to its shape, just like Jason Chung and wind chimes. Its elegant colors and green leaves are very ornamental. However, if its leaves are yellow, its value will be greatly reduced. So, let's see why this happens and how to deal with it.

Watering problem

Reason: water is an indispensable factor for its growth, but if its roots are soaked in water for a long time, it is very likely that its leaves will turn yellow and fall off.

Solution: First, adjust the watering. For this plant, it is afraid of waterlogging, so when watering, we should follow a general principle, that is, water the pot soil when it is dry, and don't water it if it is not dry. In addition, the choice of container and substrate is also very important, and the one with better drainage performance should be selected. Besides, regular ventilation is very important.

Lighting problem

Reason: Because this plant can't accept strong sunlight, its leaves may turn yellow if it is too strong or exposed to direct sunlight for a long time.

Solution: Reduce the illumination time appropriately. If the light is particularly strong in summer, remember to move the plants indoors or take other shading measures.

undernutrition

Reason: We all know that plants may turn yellow if they lack nitrogen fertilizer for a long time, so this is also a possible reason.

Solution: supplement N-rich fertilizer and pay attention to balanced nutrition.

Soil discomfort in basin

Reason: If plants are troubled by diseases, it may also lead to yellowing of leaves, such as yellow leaf disease. The main reason of this disease is that the soil is very sticky, which leads to hardening and makes plants unable to obtain nutrients normally.

Solution: Choose suitable soil and loosen it regularly.
