I bought a couple of herbs from Sunnyside Gardens about a month ago. I wanted to build an indoor herb garden, as I do not have a yard. The mint is doing very well, but the rosemary and chives are faring poorly.
I planted the rosemary and chives in a planter box, but there is a powdery mold on the rosemary that is slowly working its way into the soil. I have sprayed the plants and soil with a solution of vinegar and water, but the plants continue to die (though there is no more mold). Help?!
