Why Are Desert Rose Leaves Turning Yellow? Latest Cause Analysis
Desert rose leaves turn yellow due to improper light, watering, temperature, and fertilizing. Keep it in full sunlight every day to promote lush growth of branches and leaves. With each watering, keep the potting soil slightly moist. The most suitable growing temperature is stable between 20-28 degrees. During the growing season, apply a phosphorus-potassium fertilizer once every half month, and apply a phosphorus-containing fertilizer once before overwintering.
Causes of Desert Rose Leaves Turning Yellow
1. Caused by improper light
Insufficient light or scorching sun causes desert rose leaves to turn yellow. Because it likes to grow in an environment with relatively sufficient light, it needs appropriate sunlight exposure. Note that when the sunlight is relatively strong in summer, appropriate shading is needed to prevent scorching.
2. Caused by improper watering
Desert rose likes to grow in a relatively moist environment. Long-term overwatering or underwatering can cause leaves to turn yellow. Therefore, during the growing period it can be watered more, but there must be no waterlogging. In autumn and winter, as it gradually gets colder, the amount of watering can be controlled, and keeping the potting soil slightly moist is enough.
3. Improper temperature
Temperatures that are too high or too low cause desert rose leaves to turn yellow. Because it likes to grow in a relatively warm environment, the most suitable growing temperature is between 20-28 degrees. Therefore, when growing it in summer, if the temperature exceeds 35 degrees, cooling measures should be taken. In winter, when temperatures are low, take insulation and warmth measures to avoid frost damage to the plant.
4. Caused by improper fertilizing
Long-term overfertilizing or severe fertilizer burn will cause desert rose leaves to turn yellow. Therefore, fertilize regularly and in appropriate amounts. During the growing period, apply a phosphorus-potassium fertilizer once every half month, and apply a phosphorus-containing fertilizer once before overwintering. In winter, stop fertilizing or do not fertilize.
