herbs have yellow spots throughout bed and in container

Zone 29605 | dawncamner added on June 18, 2018 | Answered

Hi! I've got a variety of herbs and roses planted together in one bed and they've all gotten this horrible issue with yellow/white spots and turning yellow and looking sickly. The exception are the thyme and the dill which look good and healthy. I also have some pumpkin and clematis in there that seems healthy. The worst are my rosemary, oregano and sage. They're looking AWFUL. They've been in this raise bed for almost 2 seasons now. The roses only have black spot (not the white/yellow problem) which I'm going to treat with sulfur as neem oil no longer seems to help. The yellow/white spots have even spread to my peppermint plant that is over 15 feet from this bed. I will mention that there are a lot of tree stumps sharing this soil, with lots of mushroom/fungus in them. But I've read that the stump fungus isn't harmful to other plants. Can this be a soil pathogen? What can I do to treat my edibles so that I can actually eat them? Help! Thank you!!!

Some diseases, such as fusarium wilt, cause leaf yellowing as well, although the yellowing typically starts as circles on the leaves or accompanies wilting and other symptoms such as stunted growth. In many cases of disease, disposing of the plant and soil in a plastic bag is the best option to prevent the spread of the disease to other herbs, although removing infected leaves is sometimes sufficient.
