What causes yellowing leaves on the umbrella tree? A detailed analysis for you

The umbrella tree (Schefflera arboricola) has a certain tolerance for drought and dry air, so it is not difficult to grow. However, if you do not pay attention to its growing environment, the umbrella tree is quite prone to yellowing leaves. Here we introduce some of the more common causes of yellowing leaves in the umbrella tree.

Umbrella tree

1. Low temperature: The minimum ambient temperature should be kept above 10°C, ideally between 20 and 32°C.

2. Improper watering: Do not water too frequently, and there is no need to keep the soil constantly moist. Simply water thoroughly once the surface of the potting soil has dried out. Especially when the ambient temperature is below 20°C, control the frequency of watering even more! Each time you water, water thoroughly; do not just wet the surface!

3. Long-term insufficient light: A position with inadequate light is also harmful to it. It is recommended to move it to a spot with light.

The umbrella tree likes a warm, humid environment and dislikes harsh sunlight. It is fairly shade-tolerant, and bright indirect light is most suitable when growing it. It is well suited to being planted in well-ventilated, fertile, deep soil.

How to grow the umbrella tree

The umbrella tree is a plant that everyone loves, with a very appealing name and a fresh, natural, attractive shape. It is more often grown in water, but it can actually be grown in soil as well. Below we introduce how to grow the umbrella tree.

I. How to grow the umbrella tree——water culture

Water culture of the umbrella tree first has certain temperature requirements. The umbrella tree is a plant that can endure cold, but the temperature suitable for growth is between 20 and 28°C; if the temperature is too low, cold damage can occur. Second, the umbrella tree is a shade-loving plant, and excessive light is actually harmful to it, so do not expose it to too much direct sunlight. The water quality requirements for the umbrella tree are fairly simple; do not use tap water directly, and filtered water is a better choice. For umbrella trees grown in water, a compound fertilizer can be used, and fertilizer can be applied every two weeks when the water is changed.

II. How to grow the umbrella tree——soil culture

The growing temperature for the umbrella tree is the same as for water culture; just be careful in winter that the temperature does not get too low and cause cold damage. If the umbrella tree is grown in soil, the soil needs to be kept moist and watered once every 3 days. If the potting soil is too dry, the umbrella tree

will develop yellowing leaves. For the umbrella tree, you can use a spray bottle to mist the leaves to cool them down and increase moisture at the same time. The umbrella tree should not receive too much light. Also, the best time to plant is between April and September, as this period is most suitable for the umbrella tree to take root and develop.

What to do when the umbrella tree drops its leaves: solutions for yellowing leaves and leaf drop

The umbrella tree, also known as the dwarf umbrella tree (Schefflera arboricola), can absorb nicotine and harmful gases from smoke-filled air through its leaves. If its leaves turn yellow or even fall off, it loses its value. So what should you do when the umbrella tree drops its leaves? Below we show you the solutions for leaf drop and yellowing leaves in the dwarf umbrella tree.

What to do when the umbrella tree drops its leaves: causes of yellowing leaves and leaf drop

1. Improper watering

To keep the dwarf umbrella tree growing normally, getting the moisture right is very important. If you water too little and the potting soil becomes too dry, the leaves of the dwarf umbrella tree will droop and fall off. If you water too much and the potting soil becomes too wet, root respiration is blocked and the roots rot easily, causing leaves to turn yellow and fall off.

2. Unsuitable light

The dwarf umbrella tree is a shade-loving flower, and it can normally be kept in a bright spot. If it is placed in a darker spot, it will affect the growth of the dwarf umbrella tree and cause leaves to turn yellow and fall off. However, too much light is also one of the causes of leaf drop. The dwarf umbrella tree is not suited to growing under strong light, and even a change of environment needs to be made gradually. If it is moved all at once from a place with no sunlight to a sunny spot, the leaf drop will become even more severe.

3. Improper fertilizing

The dwarf umbrella tree has a certain demand for fertilizer, especially during the growing season; insufficient fertilizer will cause leaves to turn yellow and fall off. If raw fertilizer or concentrated fertilizer is applied carelessly, causing root burn, leaf drop will likewise occur.

4. Pest and disease infestation

The dwarf umbrella tree is often attacked by diseases, such as leaf spot, which causes brown spots on the leaves when it occurs, and in severe cases causes yellowing leaves and leaf drop.

What to do when the umbrella tree drops its leaves: solutions for yellowing leaves and leaf drop

1. Apply enough fertilizer, and apply it well

The dwarf umbrella tree needs sufficient nutrients during its growing period. In summer, fertilize once a week; granular fertilizers such as nitrogen, phosphorus and potassium can be used, applied after loosening the soil. From April to September, apply a diluted fertilizer solution once a month to ensure the potting soil has sufficient nutrients, and do not apply any single element excessively.

If too much fertilizer has been applied, you can take the dwarf umbrella tree out of the pot, wash the roots with clean water, rinse them several times in a row, then soak the roots in clean water. Once the leaves have recovered, repot it in fresh soil.

2. Water correctly

When watering, be careful not to water too much; just keep the potting soil moist. In spring, summer and autumn, water about once every 3-4 days, and reduce watering in winter. When the air is dry, sprinkle a little water on the leaves from time to time to increase humidity.

3. Ensure moderate sunlight

The dwarf umbrella tree likes shade, and it will grow normally as long as it is placed in a bright spot. Except in winter, the plant can be kept outdoors or by a window, avoiding direct strong light and ensuring enough indirect light. In winter, move it indoors to a spot that gets sunlight and raise the temperature appropriately.

4. Prevent pests and diseases

Care for it carefully in normal times, ventilate promptly, and remove diseased and yellow leaves as soon as you find them. You can keep a fungicide on hand at home, and spray it once a month after dilution, which can effectively prevent the occurrence of pests and diseases.
