I bought one of seedling starter kits to grow an indoor herb garden. Once everything started to grow, there was no growth in any of the rosemary pots and then a strange cup fungus began to grow. I threw the one out, and checked back a couple of days later and they are growing huge on the sides of the other rosmary pots. Now they're spreading everywhere on all the other herbs. Any idea where this came from? I guess I'm going to throw everything out and perhaps start a new kit.
