What to Do When Golden Bell Flower Leaves Turn Yellow? Causes and Solutions
I. Growth Characteristics of the Golden Bell Flower
The Golden Bell Flower needs sufficient light to grow and is not cold-tolerant, though it can survive in shade. It suits a warm, humid climate. It is fairly vigorous and has low demands for potting soil, able to survive in slightly barren soil, but ideally the soil should be fertile and moist, acidic, with good drainage and aeration. The Golden Bell Flower is relatively branchy and needs occasional pruning.
II. Causes of Yellow Leaves
1. Physiological causes. If the branches and leaves of the Golden Bell Flower are not pruned for a long time, they grow too densely, and too many branches and leaves dry out and age, yellowing may occur.
2. Environmental causes. Sometimes overwatering causes root rot, making the plant's roots soak too long because soil moisture is too high. Yellowing leaves can also be caused by light: the Golden Bell Flower likes light, and a lack of light lowers its vigor so the leaves begin to turn yellow. But it must not be exposed to blazing sun either, as this overheats the plant beyond tolerance and causes water loss. Growing the Golden Bell Flower also has certain soil requirements: at the very least fertile with drainage, and acidic soil suits it well. But soil that is too fertile is also no good; too strong a fertilizer dressing or applying raw manure may cause "root burn," leading to yellowing and falling leaves.
III. Specific Solutions and Treatments
1. Prune branches and leaves. If the Golden Bell Flower grows too densely, yellowing leaves can also appear; we need to cut off the thin, weak and withered old branches and tend it carefully.
2. Keep the soil fertile and moist. Pay constant attention to the soil, water and loosen it, maintain its moisture and aeration, and fertilize when needed.
3. Keep light suitable and sufficient. The Golden Bell Flower loves light, so let it grow in a place with suitable sunlight, keep sunshine abundant, and avoid blazing sun.
