ðą How to Care for Ornithogalum to Prevent Leaf Spot?
ð§ How to Water
Water about once a week during growth and flowering, when the top few centimetres of soil are dry. Never leave the soil soggy: the bulbs rot easily. After flowering, when the leaves start to yellow, reduce watering and keep the bulb almost dry during dormancy.
âïļ Lighting
Needs a bright spot with at least 4-6 hours of sun a day; full sun or light shade outdoors. Indoors, place the pot at a sunny window in a cool room. With too little light the stems stretch and flower poorly.
ðŠī Ideal Soil
Loose, well-drained soil enriched with compost; sandy loam is ideal. In clay soil add sand or grit, or grow in raised beds or pots, because wet soil rots the bulbs. In pots use a well-draining bulb or cactus mix with a drainage layer.
