I have noticed recently that the leaves of my Cordyline “Red Star” have started splitting. What could be causing this damage?
Having grown a bay tree in a pot for over 5 years, with relative success, I noticed in early spring 2023 that black spots had started to appear on some of the leaves. So, I started looking into the the possible causes and remedies for this. I wanted to restore my bay tree back to full health as quickly as possible!
