What to Do When Dracaena Leaves Turn Yellow? Causes and Solutions
Dracaena is also known as narrow-leaf Dracaena, long-flowered Dracaena, etc. It is a shrub plant of the genus Dracaena in the Asparagaceae family. It has strong adaptability to light and can be displayed continuously for 2-4 weeks in a dark indoor space, and can be placed long-term in a bright indoor space. Small and medium potted flowers can accent a study, living room and bedroom, while medium and large plants can beautify and decorate a hall. Now let us take a look at what to do when Dracaena leaves turn yellow!
Insufficient Light
[Cause] Dracaena likes warm, humid and sunny environments, but it can also tolerate shade. However, if it is placed in too shady an environment for a long time, the leaves will also fade.
[Solution] Place the flower pot on a windowsill facing southeast so that it receives sufficient sunlight.
Temperature Too Low
[Cause] Dracaena likes warmth and cannot tolerate severe cold. Its most suitable growth temperature is 20-28 degrees Celsius. If the summer temperature exceeds 32 degrees Celsius or the winter temperature is below 15 degrees Celsius, Dracaena will enter a dormant or semi-dormant state. If the temperature is too low, because the root system cannot absorb enough water, yellow-brown patches will appear on the leaf tips and leaf margins.
[Solution] In summer, keep it away from air conditioning to prevent the temperature from being too low and causing physiological disease.
Pests and Diseases
[Cause] If Dracaena is kept for a long time on a balcony or an indoor windowsill, red spider mites are likely to appear. When Dracaena is harmed by them, the leaves fade, chlorophyll is damaged, dense small yellow spots and small yellow patches appear on the surface, and they gradually shrink, yellow, and wither. In severe cases they fall off, and the plant loses its proper ornamental value.
[Solution] Red spider mites often hide on the backs of branches and leaves or in places where the leaves are dense, spinning webs to hide. Manual capture is relatively easy. If chemical agents are used for control, 20% dicofol emulsion can be added to 800-1000 times water to make a solution for spraying. This pesticide has a good killing effect on adults, nymphs and eggs.
Unsuitable Soil
[Cause] Dracaena likes loose, well-drained soil rich in humus and nutrients. Unsuitable soil pH can cause Dracaena leaves to turn yellow.
[Solution] Dracaena likes acidic soil, which can be adjusted with ferrous sulfate, and it can also be used for foliar spraying.
