I've planted some herbs on my balcony in hanging flower boxes. I live in Illinois so it's pretty hot and humid around this time of the year. My parsley has been showing discoloration my basil has some kind of brown spots on some of the leaves. Also, the rosemary seems to be unable to grow new stems and the base of the existing stems is somewhat brownish. I've posted images for all three. Here are my questions:
- Parsley: I thought at first that the issue is related to the heat of the sun, but then I read somewhere that this could be fungus . Any ideas based on the pictures? I ordered a bottle of fungicide from amazon and it should be arriving tomorrow.
- Basil: in a previous thread I asked a question about finding a lot of insects in my old bag of potting mix. After seeing the comments I ended up using the soil; the basil plant seems to be the one with the most "infestation". I am unsure if these dots are a result of the insects or heat/sun related.
- Rosemary: I suspect that the roots might have rot or something. How can I be sure? Could something else be the issue?
