Oncidium naevium

Also known as: Information to be completed

A medium-sized, epiphytic orchid with upright, 20-30cm long, evergreen leaves. New growth appears from the base of the swollen stem - pseudobulb. Each pseudobulb is a storage organ for water and nutrients. They are oval-shaped, compressed and partially covered by four to five, green, leaf-bearing sheaths. The plant typically flowers in winter and spring, on 30 - 40cm long, arching stems. New flowering stems arise from the axils of young, mature pseudobulbs and the leafed sheaths. Sweetly scented, star-shaped white flowers are covered with tiny red dots and a yellow spot at the centre. Mature plants may produce six or more, 30cm long flowering stems for an impressive display.

Watering

Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

No pruning required. Cut off spent flower spikes.

Propagation

Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting.

Growing

Grow in an open bark-based orchid compost with addition of perlite, sphagnum moss or coir. Provide enough bright filtered light, but keep away from direct sunlight or a heating source. Ideal temperatures are around minimum 8°C at night and up to maximum 25 °C during day. Water regularly, when the pot feels light when lifted. Ensure that all water drains away, preventing the plant sitting wet. Orchid fertiliser can be applied regularly throughout the growing season. Reduce watering and feeding in winter months.

Common pests and diseases

Diseases

Generally disease-free. Poor air movement may cause bacterial or fungal rots. Good hygiene practice and sterilising cutting tools prevent the spread of virus diseases.
