Potting Soil – Growing Mushrooms
Q: One of my potted plumerias has dime-size red mushrooms on the soil. The plant has been on the decline for the past couple weeks. Is there anything I can do to get rid of mushrooms?
A: In my experience, mushrooms growing on potting soil means that it’s too soggy. The plant’s decline might be caused by incipient root rot in wet soil. Take the plant out of the pot, dump the soil somewhere in your landscape, and make sure the bottom drain hole is not clogged. Cover the hole with a piece of screen and refill the pot with fresh potting soil. Replant the plumeria and support the pot off the ground with three large pebbles. Keep your plants outdoors until frost is predicted then bring them inside for the winter.
