2. Anthracnose
Anthracnose is a fungal disease that causes dark spots on the leaves and stems of the plant. It is often caused by wet conditions and poor air circulation. The disease can spread quickly and cause the plant to die. To manage anthracnose, remove the affected leaves and stems, and apply a fungicide to the plant regularly to prevent further spread of the disease. It is also important to ensure that the plant is not overwatered.
Common Pests
1. Mealybugs
Mealybugs are common pests that can affect Crassula cornuta. The insects are small, white, and woolly and can be found on the leaves and stems of the plant. They suck the sap out of the plant, causing it to weaken and die. To eliminate mealybugs, wipe the plant down with a solution of water and dish soap. You can also use a systemic insecticide to prevent infestation.
2. Spider Mites
