  • No movement: Unlike pests, harmless white spots do not move or crawl on the plant's leaves.

If you observe these characteristics in the white spots on your succulents, there's no need to worry. These spots are most likely a result of genetic factors or natural variations and pose no threat to the overall health of the plant.

However, if you notice any other symptoms or the white spots are accompanied by wilting, discoloration, or unusual growth, it's crucial to investigate further. These could be signs of underlying issues such as fungal infections, insect infestations, or nutrient deficiencies.

While white spots on succulents can be a cause for concern, it's essential to consider genetic factors and natural variations as potential causes. Understanding these factors can help growers differentiate between harmless spots and potential signs of disease or pest infestation. By being observant and proactive in addressing any concerning symptoms, you can ensure the overall health and vitality of your succulent collection.
