Q.Type Of Disease And How To Treat.

Zone Sydney | Anonymous added on March 5, 2024 | Answered

I’m a novice gardener ‘renovating’ a neglected garden. Some of the plants have cobweb like webs over and under leaves which I think is spider mites. The other more difficult one is possible disease or fungus. Can you tell me what it is and how to treat?

The webs in the photo do look like a spider mite infestation. Use Neem oil, a hard spray of water from a hose, or a miticide spray.


Fungicides, particularly a copper fungicide, can help fungal spots but it is usually wasted effort after the fact. Pick off the spotted leaves and pick up any that have fallen and dispose of them in the trash. Good sanitation, air flow, and no overhead watering will help avoid spots next year.

Looks like a spider mite infestation. Use a miticide spray or a hard spray of water from a hose to dislodge these pests that suck sap from the leaves, especially newer leaves.
