What is harming my Delphiniums?
Hello Fellow Gardeners!
It has been quite some time since I have posted here, but it is nice to still see some familiar names :)
I planted Delphinium seeds (taken from a healthy plant at my previous home) 6 years ago and have since had beautiful and healthy plants - but both last year and this, something is happening (see photo). I have not made any changes to the location that they reside in ...... I do not visibly see any bugs active on the damaged parts.
Any ideas / suggestions?
