Indoor plants are very vulnerable to a number of various diseases. There are many signs and symptoms which signal disease in houseplants. It’s important to know become familiar with these signs – the sooner you catch onto a potential problem, the more likely you can do something about it and save your plant from dying.
Symptoms and Signs of Disease in Indoor Plants
Wilting: Wilting refers to leaves and flowers that are drooping. Often times, wilting is caused by not watering your plant enough, but if the plant is wilting and the soil is damp, the problem could be more serious. Fungal disease is the main cause of severe wilting. Fungal diseases typically occur because of excess watering. You should allow the soil to dry out some and then water only when the plant really needs it, as opposed to watering daily or even every other day. Once every three or four days should be enough for most plants.
Leaf Spots: Black and brown spots are also a sign of fungal disease in indoor plants. They may be large or small, but usually appear on the foliage and blossoms. There are typically many spots, which appear in clusters. Foliage will often die off, causing leaves to fall. Organic fungicide is the best treatment, such as Pure 3-way, as well as increasing air circulation. You should also place the plant in an area with better lighting.
Powdery Dust: Keep an eye out for a light, powdery dusting, which will appear on indoor plants. The dust will usually be gray or white and will cover leaves, stems and blossoms. This is caused by powdery mildew. Curling leaves is a sign of this disease as well. One of the main causes of powdery mildew is humidity, but air circulation will really help with this. Bring a dehumidifier into the room to help out. Be sure to dispose of diseased plant parts so that you don’t contaminate any healthy growth.
