Black spots on succulent leaves, probably due to disease.

During the rainy autumn season, it has rained continuously for several months in many areas. Perhaps some flower friends will find that their succulent plants are not good. Black spots appear in their leaves, and then they fall and melt water, slowly spreading from one leaf to the whole plant, from one or two succulent plants to many succulent plants. In fact, this is a common black spot in many plants, which may be less common than the origin of succulent plants, because black spot is a serious disease widely distributed all over the world outside dry areas, mostly in wet seasons.

When you find that some leaves of succulent plants turn yellow, fade or even blacken, mildew spots and softness appear, you should beware of black rot, most of which are caused by too much watering and too much humidity, so the usual ventilation is very important. Black spot, on the other hand, starts with leaves, usually black spots or round black spots, and then slowly infects other parts of the plant, seriously causing the whole succulent plant to die.

The symptoms of black spot disease of succulent plants are usually black spots on the leaves, usually round, and then the leaves will wither or melt water, gently touch and fall off, slowly all the leaves begin to grow black spots to the growing point, and then the whole plant dies. This process is usually slow, and it tends to infect other succulent plants before it dies, so it is found that isolation treatment is needed as soon as possible.

The difference between black spot disease and soot disease: the biggest difference between black spot disease and soot disease is that black spot disease is basically a few black spots (dots), while soot disease is basically a lot of black spots. In short, it is enough for beginners to remember this main difference.

The difference between black spot and black rot: very simple, black rot is the whole plant suffers, leaves and roots will slowly blacken and rot. Black spot disease is the occurrence of black spots in some areas, slowing down the water to rot away. With this in mind, you must be able to tell the difference between them. Black rot is a common disease of succulent plants, which begins to appear from the stem and slowly extends from the lower part of the plant to the upper part of the plant. The form of black rot is generally hidden, especially in places with high humidity and rainy and unventilated.

The main physical means to prevent black spot are: do not use unsterilized soil, pay attention to ventilation in the planting environment, avoid random rain during the rainy season (this is very important), and avoid long-term moisture in the basin soil. If succulent plants get black spot, basically need to spray some fungicides to cure it, when the overall planting environment improves, the symptoms will be slightly delayed.
