What to do about Monstera black spot disease

1. Symptoms

At the beginning of the disease, there will be relatively small black spots on the leaves, which will then slowly expand over time. The lesions are black at the edges, dark grey in the middle, and accompanied by black spots until they engulf the entire leaf and plant.

2. How to treat and prevent

1. If it is discovered in the early stage, the diseased part can be trimmed off. It is best to use sharp scissors that have been treated and disinfected to reduce the damage to the plant. Then place it in a place where the temperature is always controlled at around 10 degrees. The bad leaves that are cut off should be burned immediately to avoid infecting other branches.

2. The drugs used are mainly bactericidal. You can use carbendazim or Bordeaux mixture together with water. The entire plant should be sprayed without missing a single place. After spraying, it is best to put it in a windy place to dry.

3. Many diseases are caused by excessive water, so during normal maintenance, you should pay special attention to replenishing it with water and reduce the amount of watering. Replace the old soil, sterilize the roots again and then plant it. Pay attention to taking good care of it and place it in a windy location for maintenance.
