Leaf Spots

Succulents could get a lot of fungal leaf spot diseases. Leaf spots do not harm the plants significantly, even though they do not look good aesthetically. Once the fungus dominates and takes control of the plant, the small spots will get bigger and tend to look like blotches. Eventually, it will end up degrading the plant. However, if you take precautions at the initial stage, it will not be a problem as the growth progresses.

Treatment

You could conduct several remedies which are safer and convenient to treat the succulents infested by leaf spots. You could simply apply an all-purpose fungicide to them.
