Dendrobium Kingianum Care Sheet

Light: Bright to very bright

The Dendrobium Kingianum will grow at any light level, but strong light is required for full potential. In low light levels this orchid will not bloom, a sign of adequate light is a red tinge to the leaves. If the foliage is very dark green, it means the orchid isn’t receiving enough light. Keep in an eastern, or partially shaded southern exposure for adequate light levels.

Temperature: 40º F (5º C) to 85º F (30º C)

This orchid can withstand hot temperatures up to even 104º F (40º C) with good air ventilation, partial shade and good watering. In the winter time though, the Kingianum needs an extreme cool down in order to initiate flower spikes. If kept in temperatures over 50º F (10º C) in the winter time, blooming might be poor. Keep away from freezing conditions though, and start to increase temperatures as the flower spikes start to grow.

Water: Keep evenly moist and withhold watering in the winter time

In the growing seasons, usually summer and fall, water abundantly and keep evenly moist for good growth. As the temperatures drop and growths are mature, reduce watering drastically and resume watering after the flower spikes start to develop. Use a coarse medium that provides very good drainage and air flow around the roots.

Humidity: 40%-80%

Keep this plant in a more humid environment during hot temperatures, but ensure a good air ventilation as well. Misting should be performed only in the morning, to avoid standing water during night time.

Other notes:

The Dendrobium Kingianum, recently reclassified as Thelychiton kingianus, grows  in Australia and is also called the Pink Rock Orchid. This orchid is actually a lithophyte, so using a coarse medium consisting of bark and river stone will suit its needs. Some growers suggest never using a high nitrogen fertilizer with this orchid, as it will promote the growth of keikis, or offshoots, rather than produce flowers. A high phosphorus fertilizer is the most commonly used fertilizer with this orchid. In the growing season this orchid requires regular feeding with half the amount recommended by the label, but feeding should be withheld completely when canes are mature, usually in late fall and winter. Resume regular feeding after flowers fade.

The flowers range in color from white to purple, pink and even pale yellows. Blooms are small, a few centimeters in length, as every raceme can produce up to 15 fragrant flowers, lasting up to two or three months.
