rust on lamiums and rhubarb
I hate the idea of using more chemical pesticides as I've already dumped all my insecticides and currently have a bee explosion in my little urban garden
I have 2 lamiums, both looking very nice and covered in flowers (bees love them) but one plant seems to have rust coloured patches on most of its older leaves.
Rhubarb in a pot also has a coupe of leaves with similar markins.
Neither plant seems to be suffering though.
leave alone or use something organic which you clever folk would know about?
