What Causes White Spots on Jade Leaves?

There are several potential causes for white spots on jade leaves, including:

Pests:

Pests like mealybugs and spider mites can cause small white spots on jade leaves. These pests feed on the sap of the plant, causing damage to the leaves and potentially spreading disease.

Fungal Disease:

Fungal diseases like powdery mildew can cause a white, powdery coating on jade leaves. This can weaken the plant and make it more susceptible to other diseases.

How to Treat White Spots on Jade Leaves

Now that you know what causes white spots on jade leaves, let's talk about how to treat them. Depending on the cause of the white spots, there are several different treatments you can try:

Remove Pests:

If your jade plant has white spots caused by pests, the first step is to remove them. Use a cotton swab dipped in rubbing alcohol to gently wipe the leaves and remove any visible bugs or eggs.

Fungicides:

For fungal diseases like powdery mildew, you can use a fungicide spray to treat the affected leaves. Be sure to follow the instructions carefully and avoid getting the spray on other parts of the plant.

Adjust Environmental Factors:

If the white spots are caused by environmental factors, you'll need to make some adjustments to help your jade plant recover. Move the plant to a shadier location if it's getting too much direct sunlight, or adjust the temperature or humidity levels if needed.
