Purple Passion Insect Pests
Insect pests never bothered my Purple Passion, but I’ve heard people complain about the issue.
Aphids, Spider mites, and other sap-sucking insects cause yellow spots on the affected leaves. Check the lower sides of such leaves to find the insect pests.
These insect pests hang around the leaves of Purple passion and suck the plant sap through the foliage. These insects secrete honeydew as they feed.
Honeydew attracts various types of fungi and they form a black, sticky substance called Sooty mold. You need to respond as soon as you see these signs.

- Hang yellow, sticky cards around your Purple Passion plant to detect insect infestations early.
- Spray the infected branches with a forceful stream of water to dislodge the insects. This works in the case of a smaller infestation.
