Turf tubers

Asked June 12, 2018, 6:11 PM EDT

Hard, mushroom-like bulbs are growing a little below the surface in some mostly shaded turf. What are they? Thanks!

The brown balls or tubers in your lawn are mushrooms folks commonly call puffballs. These are not edible. Cut one in half to confirm it isn't a plant root. You may remove them, or just let them finish their life cycle.
