Houseplants are a great way to bring greenery indoors, but they can also be prone to various diseases. These diseases can be caused by fungi, bacteria, viruses, and pests, and can cause a range of symptoms such as yellowing leaves, wilting, stunted growth, and even death. In this blog, we will discuss some of the most common houseplant diseases and how to treat them.
Root Rot
Root rot is a fungal disease caused by overwatering and poor drainage. The symptoms of root rot include yellowing leaves, wilting, stunted growth, and leaf shedding. If left untreated, root rot can ultimately lead to the death of your plant. To treat root rot, you need to remove the affected plant from its pot and snip off any affected roots. Rotten roots will be brown or black in color, soggy or mushy, and may have a foul odor. Once you have trimmed back the affected roots, you can repot the plant in fresh soil. Make sure the new pot has adequate drainage to prevent another episode of rot.
Powdery Mildew

You can then spray your plant with a homemade solution of castile soap and water, neem oil, insecticidal soap, or a systemic pesticide to treat the remaining infestation.
