What is Black Spot Disease?

Black Spot Disease (BSD) is a very dangerous fungus that affects many types of houseplants. The symptoms are not visible at first, but they become apparent after several days or weeks. These include yellowing leaves with black spots on them, which eventually turn completely black. Sometimes the spots appear only on one side of the leaf; other times they spread from one side to another and even to other parts of the plant.

The disease is caused by a type of fungus called Phytophthora infestans. It usually attacks tropical houseplants such as palms, palm trees, and other evergreen shrubs. But it can affect any kind of houseplant if the conditions are right.

Symptoms of BSD: Leaves turning black and dying

How to Prevent Black Spot Disease: Avoiding the Problem!

It is better to avoid the problem than to suffer from it. There are some simple things you can do to prevent the disease:

Wear gloves when handling your houseplants. If you don’t wear gloves, then you might touch the infected area accidentally and get sick yourself. Do not use your hands while cleaning around your plants or touching them. Never wash your hands before eating food prepared outside.

The fungus can spread to any tool or surface that comes in contact with the plant. After using your tools, wash them with detergent and hot water. Always keep your houseplants away from areas where food is prepared or served.

If you see small black spots on the leaves of your plants, they might be infected with BSD. Move these plants away from the others. Also keep your plant at least three feet away from others to avoid putting other plants at risk.

How to Identify and Treat Black Spot Disease: The Symptoms!

You can identify a black spot disease infection by the telltale signs of black bugs on plant leaves. These spots eventually turn into large black areas that resemble bruises. If you observe these symptoms, move the infected plant away from others to prevent the spread of the disease.

The good news is that you can treat BSD by using common household products and fungicides. Soak a cloth in alcohol and wrap it around the infected parts of the plant. This kills the fungus right away. You can also use a bleach solution to disinfect the affected leaves.

If the entire plant is affected, you should prune away about two thirds of it and dispose of it in a plastic bag. Then, put the plant in fresh soil and apply a mixture of baking soda and water to it. Always remember to wear gloves when you treat it with fungicides!

How to Prevent Black Spot Disease: General Rules!

The fungus that causes black spot disease thrives in warm, damp conditions. Make sure you water your houseplants in the morning so that the soil can dry out during the day. Do not put them next to a draft, as this will also make them more susceptible to BSD. Lastly, do not crowd your houseplants. Allow air to flow freely around them.

If you follow these tips, then you will already be helping your houseplants to avoid Black Spot Disease. If you ever suspect that your plant might be infected with it, make sure to treat it right away. Proper treatment is the only way to save your plants from this deadly disease!
