What to Do When Dragon Tree Leaves Turn Yellow? Find the Cause and Treat It Accordingly
The dragon tree has won people's affection thanks to its own distinctive features. Some friends who grow dragon trees always find that the leaves turn yellow. So what should be done if the leaves of a dragon tree turn yellow? Let us take a look together.
Introduction to the Dragon Tree
The dragon tree is also called the dragon's blood tree. It originally comes from the tropics and subtropics of the Canary Islands, Africa and other places. The plant has a robust and handsome overall form, and its leaves are colorful and varied. Its resin is red, similar to dragon's blood, which is how the dragon's blood tree got its name. When the plant is a seedling, its leaves are bright green; as the plant grows, the color gradually changes to bright red or purplish red, milky white, bronze and other colors, making the colors extremely rich and gorgeous. For this very reason, its price also rises higher and higher as the age of the plant increases.
How to Grow the Dragon Tree
Soil medium: The dragon tree prefers loose and fertile soil and medium. If soil culture is used, garden soil, leaf mold, decomposed organic fertilizer and river sand can generally be mixed in a ratio of 5:3:1:1, which can provide the basic nutrients for plant growth. It has a high requirement for soil looseness, so the soil should be turned and loosened in time, generally once a month, to ensure good soil permeability, and especially to prevent water from accumulating in the soil.
Temperature and light: The dragon tree loves direct sunlight, but it can also tolerate shady environments. Therefore, many growing enthusiasts place it in relatively dark rooms such as a study. Although it is shade-tolerant, not receiving light for a long time will cause its leaf color to fade, so it is best to let it receive direct sunlight at intervals, and it can also be placed near a balcony. However, in the hot summer, direct sunlight is too intense, and at such times it should be shaded and receive only 40%-50%, otherwise the leaves will be scorched.
Pest and disease control: The dragon tree is easily affected by red spider mite pests, which are a type of mite infestation. Red spider mites appear in clusters, spinning webs and gathering on the back of the dragon tree's leaves, living by sucking the plant's sap. Red spider mites cause the dragon tree's leaves to fade, producing yellow spots on their surface, and even shrinking, withering and finally falling off. Red spider mites can be caught by hand or killed by spraying with chemicals. Red spider mites usually hide on the back of the leaves, and a 20% dicofol emulsion mixed with 800 times its volume of water can be made into an insecticide that can effectively kill adults and eggs.
Dragon Tree Prices
The dragon tree is a perennial evergreen tree, and its price is greatly related to the age of the plant. A small sapling can be bought for only about 10-20 yuan, while a potted dragon tree about half a meter tall costs more than one hundred yuan. A dragon tree over a hundred years old can rise to tens of thousands.
What to Do When Dragon Tree Leaves Turn Yellow
The yellowing of dragon tree leaves may be caused by overwatering. The watering principle for the dragon tree is to water when dry and let it dry between waterings, and to water only after the soil has dried completely. In winter, the amount of watering should especially be reduced, and when watering, water must not be poured into the heart of the tree. Too strong direct sunlight can also cause the leaves to turn yellow. If the leaves turn yellow and the stem becomes soft and cannot stand upright, check whether it is rotting; if it is rotting, cut it off and clean it up in time. Then loosen the soil, water an appropriate amount, and place the plant in a ventilated and cool place for a period of time, and it will naturally grow new shoots.
