Water every 3-4 days keeping the soil slightly moist. Allow the top third to dry between waterings. Avoid waterlogging which causes root rot. Reduce watering slightly in winter.
Lighting
Place in bright indirect light. Avoid direct sunlight which can scorch the leaves. Ideally near an east or north-facing window with a sheer curtain.
Ideal Soil
Use a well-draining, organic-rich potting mix. A blend of equal parts peat, perlite, and orchid bark works perfectly. Maintain pH between 5.5-6.5.

Common Problems
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.
Gray Mold (Botrytis Blight)
Gray mold, caused by the fungus Botrytis cinerea, is one of the most common fungal diseases in plants. It affects over 200 plant species, including ornamentals, vegetables, fruits, and houseplants. The disease thrives in cool, humid conditions with poor air circulation, causing grayish spots and soft rot on infected tissues.
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
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.
