Sir,

I truly appreciate your show on the radio! What do you think is growing in my rosemary plant?

Many thanks for your time!

These are mushrooms being produced by a fungus that is decaying organic matter in the potting mix. They are harmless to the rosemary. Remove them as they appear, if you like.

But, this is a sign the soil is staying wetter than a rosemary plant would like. Another sign the soil is staying too wet is the dark, dying foliage at the base.

If it is the rain keeping the soil too wet, there is nothing you can do about that. But, watch your watering. The soil should feel dry when you stick your finger in it before you water. Make sure the drainage hole is open and the pot is draining well.
