ðą How to Care for South American Slipper Orchid to Prevent Bacterial Soft Rot?
ð§ How to Water
Water often enough that the medium is always slightly damp - in warm weather this can mean 2-3 times a week. Use rainwater, distilled water or low-mineral tap water at room temperature, and flush the pot thoroughly each time so salts never build up around the sensitive roots.
âïļ Lighting
Give bright, indirect light such as an east-facing window or a lightly shaded south window. Direct midday sun will scorch the foliage, while too little light is the most common reason Phragmipediums fail to bloom.
ðŠī Ideal Soil
Pot in a fine, fast-draining mix of small orchid bark and perlite (or a bark-compost blend) that holds moisture without turning soggy. Repot every 1-2 years before the mix breaks down, since decomposing bark is the leading cause of root and crown rot.
