What to do when Portulacaria afra 'Variegata' drops leaves? Find the cause and treat it accordingly

Portulacaria afra 'Variegata' is a plant with high ornamental value, also known as variegated elephant bush. This plant is native to South Africa, and its leaves go through a color-changing process as it grows. It has small pale pink flowers and is usually widely grown as a foliage plant in temperate and tropical regions around the world. However, leaf drop often occurs during cultivation. What causes this? Let Qinnong Wang explain below.

I. Causes of leaf drop in Portulacaria afra 'Variegata'

1. Scorching sun

Portulacaria afra 'Variegata' likes a sunny environment and is fairly drought-tolerant. If it cannot get sunlight for a long time, the variegated colors on the leaves will fade and the internodes will stretch, making the plant loose and not compact, which affects its ornamental value. However, if it is exposed to scorching sun in summer, leaf drop is very likely to occur.

2. Black rot

Black rot is one of the most common diseases of succulents, usually a fungal infection caused by overwatering or an overly humid growing environment. It generally causes symptoms such as leaves becoming soft and leaves dropping.

3. Water

Both lack of water and excess water can cause leaf drop. The difference is that lack of water not only causes leaf drop but also makes the leaves wrinkled. If the plant is only dropping leaves without the leaves wrinkling, then it is not lack of water and may be caused by too much water.

4. Acclimation after repotting

This is a fairly normal stage, usually a problem that appears only after just repotting or just bringing the plant home. Having just encountered a new environment, the root system has not yet adjusted, so leaf drop occurs. This can be regarded as a normal metabolic process.

II. Solutions for leaf drop in Portulacaria afra 'Variegata'

In daily care, generally water less, give more sun but not scorching sun exposure, and also be sure to maintain a ventilated environment. If black rot occurs, you can use a clean knife to cut off the diseased part, then apply the corresponding fungicide for disinfection.
