I live with my Mom and recently the responsibility of looking after the garden was handed over to me. Of course, as soon as I looked at the plants almost all of them are diseased or showing signs of other problems. I’ve attached photos of the problems and I was wondering if anyone has any idea what the problems are and how I can fix them (preferably with things I have in the house). In order, the plants are a sage, a red robin, a rosemary, a lavender and a mugwort if that helps.
