Just like people or pets, houseplants, on occasion, can become diseased, which, in many cases, can lead to death. However, by knowing the warning signs, you may be able to stop the problem before it’s too late. The most effective way to defend your plants against disease is to provide them with a suitable growing environment. This means using the right soil, not crowding plants, avoiding drafts, and providing adequate temperature, humidity, light, water and drainage.
Signs of Common House Plant Diseases
It’s not difficult to tell when plants are being attacked by disease. You’ll notice a slow in growth, yellowing leaves, or white powdery blotches. Leaves that have been affected will fall, stems may become soft and mushy, with black tissue near the soil.
Waterlogged soil causes roots to suffocate and die, turning them into a spongy, black mess. You can spot root problems by the plant appearing wilted even though the soil is adequately moist.
Learn to identify the symptoms of these common diseases:
- Gray mold: This fungal disease can attack every part of a plant. To prevent this, remove dead leaves or flowers from stems and soil, and provide proper air circulation.
- Powdery mildew: White powder appears on leaves when they’ve been attacked by powdery mildew. It doesn’t kill plants, but can make them very weak. Increased air circulation can help prevent this problem.
- Leaf spot: This will cause yellow, brown, black or water-soaked spots to appear on the leaves of your plant. When the case is severe, separate spots unite and kill the leaf. It also causes brown dusting on the leaves and blooms. This disease occurs in high temperatures and humidity as well as poor air circulation.
- Root rot: Early symptoms of root rot include wilting and yellow leaves. In severe cases, the whole plant will fall. Root rot occurs because of poor drainage and overwatering.
Dealing With Diseased Plants
Follow these steps to prevent disease:
- Isolate diseased plants.
- Wash hands between working with each plant.
- Sterilize tools between working with plants.
- Be sure to not overwater or underwater.
- Double-check lights and adjust them according to the needs of your plants.
- Avoid crowding plants and promote good air circulation. You may even want to use a small fan to improve airflow.
