I have also covered problems with yellowing leaves and dropping leaves in my guide here. In this guide, I cover some other pests and diseases that are attracted to photinia’s and discuss what to do about these photinia…
Following on from my guide on growing photinia, I’ve got a couple of lollipop photinias in large pots as well as an established Photinia hedge so I’ve had my fair share of problems with the leaves on my photinias turning yellow and falling off.

Delphinium problems include several fungal diseases, bacterial problems, viruses, and infestations of pests and other bugs. Unfortunately, once infected, many of these plants can’t be saved.

I have also had issues with powdery mildew. Usually, I spray with a fungicide as soon as I notice mildew…
