Rosemary

Question

My rosemary is not looking good. I have it in a pot sitting in a sunny window. I used miracle grow potting soil. It is not over watered (once a week). It has been in pot about 2 months.

It has grayish coating in leaves. Limp looking.

Answer 1

That appears to be powdery mildew. This can be fixed by spraying with neem oil. Just be sure to wash it off before you use it. I don't ever recommend using miraclegro on anything that you intend to consume. It is usually a little overbearing to plants like this anyway. I recommend a good organic potting mix, or adding organic compost to a decent potting mix.
