What to Do When Desert Rose Leaves Turn Yellow? A Detailed Guide to Repotting Precautions
Although the desert rose is a type of succulent, it neither has the “chubby” look nor is it as elegant and charming as a rose. Yet the desert rose's unique charm still attracts many people. The desert rose's flowers are very beautiful and vibrant, with high ornamental value, but if a pile of yellow leaves hides beneath this beauty, its ornamental value is naturally reduced a great deal.
What to Do When Desert Rose Leaves Turn Yellow
1. Environmental changes
The desert rose can survive in arid environments, and it does not tolerate humid conditions. Therefore, if it is watered too much, or left out in too much rain during the rainy season, and on top of that the air cannot circulate and the light is weak, the desert rose will develop yellow leaves.
Solution: In daily care, understand its growth habits and provide reasonable care according to its condition to prevent this from happening.
2. Overwatering
The desert rose does not tolerate humidity, so it must not be watered too much; otherwise water will accumulate around the roots, causing root rot, which in turn makes the leaves turn yellow and fall off, and can even cause the plant to wither.
Solution: Cut away the rotted roots, and pay attention to watering the desert rose reasonably and sparingly. The desert rose is drought-tolerant, so it does not need much water.
3. Fertilizing at low temperatures
The desert rose enters dormancy in winter, and it may dry out and drop its leaves in order to reduce its own water evaporation and protect itself. At this time, it must not be fertilized too much or too strongly, otherwise the leaves will turn yellow and the plant may even die.
Solution: Maintain a suitable temperature and fertilize in reasonable amounts, not too much. It is best to place the desert rose in a greenhouse for cultivation.
4. Poor ventilation
The desert rose likes warmth and a well-ventilated growing environment. Poor ventilation will cause the plant's roots to rot and its leaves to turn yellow.
Solution: Place the potted desert rose in a ventilated spot indoors, such as a balcony or windowsill, for growing.
5. Pests and diseases
Its main pest is scale insects. When the infestation is severe, it can cause the whole plant to drop its leaves, stop growing, and eventually die. Solution: If scale insects are found, promptly use a 40% omethoate emulsifiable concentrate solution diluted 2000 times for spraying control.
What to Pay Attention to When Repotting a Desert Rose
1. The desert rose likes sandy soil with good drainage. When repotting, it is best to add more river sand or small gravel to ordinary potting soil, which can improve the drainage of the potting soil.
2. Desert roses in the seedling stage should be repotted every year. Before repotting, stop watering first, then after the potting soil has completely dried, tip the plant out, clear away the old potting soil and prune the root system, then replant it.
3. Pay attention to ventilation and water accumulation in the pot, otherwise root rot is easily triggered; do not water too frequently or fertilize excessively.
How to Care for a Desert Rose in Winter
1. Light
The desert rose is native to East Africa and the southern Arabian Peninsula. So it likes to grow in high temperatures, an arid climate and an environment with plenty of sunlight. The desert rose is afraid of cold, so in winter it is best to put it indoors, preferably behind a window where it can get sunlight, and keep it dry.
2. Watering
The desert rose is extremely drought-tolerant, so each time you water it, you must not give too much. If you water too much, its roots will rot. Winter temperatures are relatively low, so watering should be controlled even more appropriately; watering once a week is enough. Also pay attention to keeping the potting soil dry, as this promotes the growth of the desert rose.3. Soil
Because of its growing conditions, it also has certain requirements for soil quality. Sandy soil has good drainage, so it is the first choice. During its vigorous growth period, we can add some small gravel or river sand to its growing medium, which helps with drainage. A mix of leaf mold and fertile, loose sand is the best.
4. Fertilizing
When fertilizing the desert rose, under normal circumstances, applying a phosphorus and potassium fertilizer once a month is enough. But in autumn and winter it enters dormancy, when its growth is very slow and may even stop. So in autumn and winter there is no need to fertilize.
How to Water and Fertilize a Desert Rose
1. Spring and autumn
Spring and autumn are the periods of most vigorous growth for the desert rose. During this time, water it thoroughly to keep the potting soil moist, but at the same time be careful not to let it become too wet. When watering, pay attention to watering when dry and letting it dry between waterings, and water thoroughly when the soil has dried out. In early spring and late autumn, temperatures are relatively low, so watering needs to be appropriately restricted.
2. Summer
In summer, during its vigorous growth period, sufficient fertilizer and water must be ensured, so that the flowers it produces are abundant and vibrant. In addition, when repotting once a year, you can also appropriately apply some long-acting base fertilizer in the pot, such as decomposed soybean cake, bone meal, etc.
3. Winter
In winter, reduce watering to keep the potting soil dry, but when it becomes too dry, it also needs watering. The rose does not need much fertilizer. During its growing period, you can apply a dilute liquid fertilizer 1-2 times a month, and in winter, stop fertilizing. The desert rose likes phosphorus and potassium fertilizers, and normally you can give it a supplement once a month.
Although the desert rose does not grow in the desert, its place of origin is close to the desert, so it is not difficult to care for a pot of this beautiful flowering plant. In addition, the desert rose is also widely used in medicinal value and landscaping, so flower lovers who like it can give it a try.
