How to Fix Yellowing Leaves on a Radermachera sinica

Radermachera sinica (also known as the China doll or serpent tree) is a small tree in the Bignoniaceae family, genus Radermachera, also called snake tree, bean-pod tree, bone-setting parasol, and ox-tail tree. It is a relatively easy foliage plant to grow, but improper care can cause problems such as yellowing leaves, greatly reducing its ornamental value. So what should you do when Radermachera sinica leaves turn yellow? Let's take a look together below!

Metabolism

[Cause of yellowing] Radermachera sinica is constantly undergoing metabolism as it grows, so there will be the phenomenon of old leaves dying and turning yellow.

[Solution] This is a normal phenomenon; simply cut off the yellow leaves, and no special care is needed.

Caused by lack of roots

[Cause of yellowing] If your Radermachera sinica was just bought, it may be because the plant has no roots - freshly sawed cuttings placed in a pot and sold (flowers bought from mobile vendors are prone to this situation).

[Solution] Handle it according to the actual situation: return it, or let the Radermachera sinica rest quietly until it sprouts new roots.

Sudden environmental change

[Cause of yellowing] Because of a sudden environmental change, with temperature, humidity and light changing too drastically, or repotting that damaged the roots and requires a recovery period, the leaves turn yellow.

[Solution] There is no need to worry in this kind of situation; you can take measures to reduce the degree of environmental change, and once the Radermachera sinica adapts, it will be fine.

Improper watering

[Cause of yellowing] Overwatering blocks root respiration or even causes rot, affecting absorption and causing a large number of yellow leaves.

[Solution] Pay attention to watering by checking the topsoil; do not wait until the soil is completely dry before watering. When you water, water thoroughly, and do not keep the frequency fixed for a long time.

Dry air

[Cause of yellowing] Poor indoor ventilation and air movement lead to dryness, causing the leaf tips to turn withered and yellow.

[Solution] Increase indoor ventilation and air movement, and you can also spray water appropriately to increase indoor humidity.

Insufficient light

[Cause of yellowing] It may be caused by the plant being in too dark an environment with insufficient light.

[Solution] Give the Radermachera sinica plenty of sunlight, but avoid exposure to harsh direct sun.

Over-fertilizing

[Cause of yellowing] Is the amount of fertilizer too large, and is the organic fertilizer applied fully decomposed, and so on.

[Solution] At this point you can flush the potting soil with water to dilute the fertilizer strength, but be careful not to cause waterlogging.
