1. Natural phenomenon: the appearance of white spots on the original stone flower may be a natural phenomenon. White spots will appear on the surface of some rough flowers during their growth, which is usually caused by insufficient or excessive ultraviolet radiation. These white spots will not affect the health of plants, nor will they affect their ornamental value.
2. Disease: The white spots on the original stone flowers may be caused by diseases, such as powdery mildew and rust. These diseases will cause white spots on the surface of raw stone flowers, and even make plants wither. In this case, it is necessary to take corresponding preventive measures, such as spraying fungicides.
3. Insect pests: The white spots on the original stone flowers may be caused by insect pests, such as scale insects and whiteflies. These pests will suck the juice on the surface of the original stone flower, leading to malnutrition and white spots on the surface. In this case, it is necessary to take corresponding preventive measures, such as spraying pesticides.
4. Sunburn: The white spot on the original stone flower may be caused by sunburn. If the original stone flower is exposed to strong sunlight for a long time, white spots may appear on the surface and even dehydrate the plants. In this case, it is necessary to move the raw stone flowers to a ventilated and cool place for maintenance.
In a word, the white spots on the original stone flowers may be caused by natural phenomena, pests and diseases or sunburn. If the white spot does not affect the normal growth of plants, it can be left untreated; If the area of white spots is large or affects the health of plants, corresponding prevention measures should be taken in time.
