Causes and Solutions for Blackened and Falling Leaves on White Jade Orchid (Michelia alba)

White Jade Orchid (Michelia alba) is a relatively tall tree, evergreen all year round, with a very tall and sturdy form. This plant, which looks rugged on the outside, produces slender, pure white, beautiful flowers with a fragrant scent that makes people feel completely refreshed and relaxed. However, White Jade Orchid is prone to a troublesome problem: its leaves turn black and drop. Today we will talk about how to deal with it.

Chlorosis

To prevent and treat the problem of White Jade Orchid dropping its leaves, you first need to understand the causes. In fact, it is not hard to see that when this happens, there must be a problem with plant management. One of the main causes is that the leaves may have contracted chlorosis. The symptoms show the newly sprouted tender buds at the tips of the branches losing their proper green color, then gradually showing a top-down trend, slowly extending downward. If measures are not taken in time to treat it, the leaf veins will turn yellow and scorched, and finally the leaves will drop.

In this case, you can appropriately supplement the plant with some ferrous sulfate. It can be applied to the soil, or a small ferrous sulfate granule can be buried in the cortex below the plant and then wrapped with plastic film. It can also be diluted with water and sprayed onto the diseased leaves in mist form. Repeating this for several cycles can cure it.

Anthracnose

The greatest harm of anthracnose is that it attacks the leaves of White Jade Orchid. In the early stage, it mainly shows as a small faded spot on the leaf surface, which then gradually expands, and in the later stage develops to occupy half or even the entire leaf, with scorched margins and blackened leaf edges, followed by intensified leaf drop. The best method is to use the drug anthracnose Fumei, diluted with water in proportion and sprayed on the affected areas, which can improve the situation.

Improper Care

Besides the two main causes above, improper daily care is also deeply connected to this problem. Therefore, the editor reminds everyone here to be sure to provide attentive, scientific and reasonable care.
