Common Houseplant Diseases and How to Treat Them

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

Powdery Mildew

Powdery mildew is a fungal disease that affects the leaves of plants, causing a powdery white or gray substance to appear on the leaves. The leaves may also turn yellow and fall off. To treat powdery mildew, you can use a fungicide spray or a homemade solution of baking soda and water. Mix 1 teaspoon of baking soda per quart of water and spray over the entire plant. You should also remove any affected leaves and improve air circulation around the plant to prevent another outbreak.

Leaf Spot

Leaf spot is a bacterial or fungal disease that causes brown or black spots to appear on the leaves of plants. The spots may also have a yellow halo around them. To treat leaf spot, you should remove any affected leaves and improve air circulation around the plant. A fungicide spray or a homemade solution of vinegar and water will help treat a fungal infection, but will not be effective for a bacterial infection.

There is no treatment for bacterial leaf spot. The best chance of saving a plant with bacterial leaf spot is to remove all affected leaves, quarantine the plant, and observe for improvement.


Mealybugs are small, soft-bodied insects that can infest houseplants. They are often found in clusters and can cause damage to leaves and stems. Symptoms of mealybugs are yellowing leaves, leaf shedding, and deformed leaf growth. To treat mealybugs, use a q-tip or toothbrush soaked in rubbing alcohol to remove visible pests. You should also use insecticidal soap, neem oil, or a systemic pesticide to treat the infestation.

Spider Mites

Spider mites are tiny, spider-like insects that can wreak havoc on houseplants. They often infest the undersides of leaves and can cause yellowing and curling of the leaves. To treat spider mites, use a shower or kitchen sink sprayer to remove the bulk of the insects from the plant. 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.
