Jade Plant Pests: Identifying and Treating Jade Plant Diseases

Identifying and treating jade plant diseases and pests are an essential part of ensuring the proper growth of the succulent plant species. 

Jade Plant Pests

Although the Crassula ovata or Jade plant is regarded as an easy-to-grow, low-maintenance plant, it does suffer from a few pests and diseases that could threaten the overall health of the plant. Here are a few. 

Spider Mites

Spider Mites on jade plants are common. They are small or tiny motes that produce tiny webbings all on the undersides of the plant’s leaves and stems. 

They spread with ease from an infested plant to another and can survive by sucking up sap from the leaves of the jade plant. 

Aside from the visible white spider-like webbings on the plant’s leaves, spider mites are known to cause little dark spots on the plant’s foliage. 


Mealybugs on Jade Plant are a lot easier to spot than a spider mite. They are known for their white, fluffy bodies. 

Mealybugs hurt the Jade plant in numerous ways. One is through biting and sucking up the plant’s sap from its foliage. Another is by leaving sugary droppings that are known to attract other pests. 

You can identify the mealybug on a jade plant by looking at the plant’s leaf stem. There you would find them with ease.

They are hard to spot as they feature tiny green bodies that often blend in with the Jade green leaves. However they are known to cause dark spots on the plant’s foliage, these can be used to identify them. 

In addition to that, aphids also leave behind droppings that attract other insects and encourage diseases for the jade plant.     

Powdery Mildew on Jade Plant

Powdery Mildew is not an insect infestation but a fungal infection. It can be identified as white sticky stuff on jade plant leaves. 

This fungal infection might start small, but they fast spread across to other parts of the plant and in no time it could cover a large portion of the plant in white dust. 

Overwatering the Jade plant can result in a Powdery Mildew infestation. And leaves affected by this pest would require pruning as they are impossible to recover from. 

Scales on Jade Plant 

Scales are difficult pests to notice on the Jade Plant, as they are tiny and slow, making it easy to overlook the pest.
