Dendrobium amethystoglossum

Plants are best grown mounted on cork bark or wood if grown in conditions where sufficient humidity can be provided during the growing season. Alternatively, grow in a pot or basket, in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. If mounted or grown in a basket, the plant will develop more pendulous form. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. Provide bright light and high humidity in spring and summer. Minimum winter temperatures are 12°C and maximum summer temperatures are 22-24°C. Plant grows best with an amplitude of 8°C between day and night time. Plant requires a period of rest in winter - reduce watering and feeding in autumn, until warmer temperatures initiate new growth in spring. See indoor orchid cultivation

No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled - usually after few years of growth. Oldest canes may be removed as long as there are enough younger canes on the plant.

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.

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

Generally disease-free.
