🔍 Possible Causes (8)
Fungus Gnats
Fungus gnats are small, gray-to-black mosquito-like insects (1/8 to 1/10 inches long) commonly found in indoor plants. Adult gnats are mostly a nuisance, but their larvae feed on plant roots and organic matter in soil, potentially causing serious damage to young or vulnerable plants. The larvae are translucent white with distinctive black heads and can leave slime trails on the soil surface in heavy infestations.

Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.

Remove heavily infected areas
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.

- • Yellow or brown limp, droopy leaves that feel soft and mushy
- • Wilting despite wet soil

Cold Damage
Cold damage, also known as frost injury, occurs when plants are exposed to freezing or near-freezing temperatures. This environmental stress can cause cellular damage as ice crystals form within plant tissues, rupturing cells and disrupting normal plant functions. Chilling injury can also occur in sensitive species at temperatures between 32-55°F (0-10°C), even without actual freezing.

Stem Necrosis
Stem necrosis is a condition characterized by the death of plant tissues on the stem, leading to browning, blackening, and eventual decay. It can weaken the plant, hinder nutrient and water transport, and in severe cases, lead to plant death. This condition can be caused by various pathogens, environmental stresses, or physical damage.

Fungicide Application
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.

Emergency unpotting
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.

Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.
