Watering. Keep soil moist but not waterlogged. Overly wet soil encourages mushroom growth. Allow the top layer of soil to dry slightly between waterings.
Fertilizing. No fertilizing is needed for the mushroom itself. For the potted plants it grows in, use balanced fertilizer as recommended for the specific plant species.
This mushroom often appears in moist, well-watered potted plants. It does not harm the plant but indicates rich, damp soil. No special care is needed to remove it, but reducing watering can help prevent its growth.
