Q.Why do my outdoor plants have yellow leaves?
Hello, I have a few plants in my courtyard and they’ve all started to have yellow leaves two months ago. I stopped watering them in case it might be the issue, but nothing has changed. I’ve also noticed a white bug on a plant but it only happened once. Thanks in advance for your help!

Unfortunately, the watering may have stopped too late. This is an infection likely caused by overly wet soil.
From here you will need a fungicide.
They also require quite a bit of shade, so if this receives full sun, then this will cause the tree to succumb to the disease much faster.
