What are the black dots on my plant stems?
Spring black stem and leaf spot is caused by the fungus Phoma medicaginis var. medicaginis. This fungus survives the winter as pycnidia or dormant mycelium in overwintered stem lesions or fallen leaves. Symptoms occur primarily on stems and leaves but seedpods, crowns, and upper taproots also may become infected.
Why is my Monstera stem turning black?
Stem rot is caused by fungal pathogens present in the plant’s soil. This disease often starts in the roots and works its way up the plant, spreading to the stems and eventually the leaves until the plant completely dies. Since the disease begins in the roots and the soil, it often affects the bottom of the plant first.
How do you fix Monstera stem rot?
Carefully remove your monstera from the pot (you might need a friend to help you) and rinse as much of the soil off the roots as you can. If you see any rotting roots, carefully trim those away. Then repot the plant into fresh soil in a clean pot with good drainage. (You can get a new one or clean the old one.)
