| Do you mean mushroom from to much moisture? A mushroom plant, or mushroom shape base on the trunk itself, as if infested by a parasite or something? If a mushroom growing from soil then, How long have your plants been in that soil and what kind of soil? I would immediately bareroot them, and place them in a much better draining open soiless mix, and stick them in light for a few days, then as much full sun as possible there after..Of course this is if they are staying damp too long..:-) Can you you post a pic? Thankyou |
