Dendrobium loddigesii

Loddiges' dendrobium

A small-sized, semi-evergreen orchid with up to 10cm long, pendulous, cane-like stems. The stem is covered with alternate, thin white, leaf-bearing sheaths. The leaves are fleshy, bright or dark green, 4-6cm long. Short flowering stems carrying a single, 5cm large flower emerge from the nodes in the upper third of leafed, or leafless stems. Long-lasting, fragrant flowers are pale pink or pale purple. The lip is round, with fringed white edge and yellow/orange centre.

How to grow

Cultivation

Plants are best grown mounted on cork bark or wood if sufficient humidity can be provided. Alternatively, grow in a basket in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. Re-pot before the potting mix starts to decompose, ideally in spring when the new growth appears. The average temperatures are 20-25°C in summer and 8-14°C in winter. Provide indirect light and high humidity by misting regularly in spring and summer. Ensure that roots dry-out between the waterings, especially in winter. See indoor orchid cultivation

Propagation

Propagation by seed is only possible in controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes - remove and pot them into sphagnum moss when the new roots are at least 2cm long.

Pruning

No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are enough, younger, thick, leaf-bearing canes on the plant.

Pests

May be susceptible to scale insects, aphids, mealybugs and red spider mite.

Diseases

Generally disease-free.
