Incredible flowers. Specimen plants can reach heights over 3 feet. These are very large plants and both sizes are in spike when listed as so in our In-Spike/In-Bloom section. Watch a video about this plant:
Intro:Dendrobium spectabile is a warm growing species native to New Guinea and the Solomon Islands. The 18 inch to 2 foot long canes produce masses of flowers that look like aliens from another world. The plant is easy to grow and flower if you follow the recommended cultural instructions. The flowers are long lasting and have a honey like scent.
Light:This plant requires good light to grow and flower properly. We recommend from 2000 - 4000 foot-candles. During the winter months when the days are short, 3500 - 4000 foot-candles is best. During the longer days of summer light levels can be reduced to 2000 foot-candles. With higher light, increase air movement to prevent burning. This plant will also grow well under High pressure sodium fixtures. Grow at three to four feet from the bulb.
P.L. Lights systems are a great way to provide artificial light to your orchids. See our P.L. Lights page for more information on this great product we offer.Humidity:50% or higher is ideal. The use of humidity trays or room humidifiers is beneficial.
We offer two products that can help increase humidity levels. The humidity tray offered in black or white, and the Mist Maker. Water:It is best to use rainwater, distilled or reverse osmosis water. Municipal water with a pH of 7.5 or lower can also be used. Water as the mix just dries out. When in spike or in flower water as the mix approaches dryness but do not allow the mix to become completely dry between watering.
Overwatering can cause several problems such as root rot and infectious bacteria/fungus in the potting medium. One product we offer that can help these problems if caught at an early stage is Phyton 27 bactericide and fungicide.Fertilizer:We highly recommend using Green Jungle Orchid Food, especially formulated to work with rain, distilled, reverse osmosis water or water low in alkalinity. Fertilize with Green Jungle every time you water if plants are planted in bark. Be sure to flush the mix with clear water only once per month to prevent fertilizer salt build up. For plants in moss or mounted on slabs feed every third or 4th watering as the moss holds a lot of nutrients.
GrowMore 20-10-20 Ureafree for municipal or well water. Use at the rate of ½ teaspoon per gallon. If using GrowMore with rain, distilled, or reverse osmosis water, add back in 5 - 10% municipal or well water to supply the necessary calcium and magnesium. Fertilize every other watering in the summer and every third watering in the winter.
Another fertilizer offered is: GrowMore 6-30-30 (Cymbidium and bloom boosting formula).Flowering:This plant typically flowers in the winter and early spring months but can also flower in late August through October. Each flower spike can produce 10 - 20 three inch flowers colored in cream, tan, mahogany, purple, and green. The flowers last a couple of and have a nice honey-like fragrance.Repotting:Repot in the spring months after flowering. Use a medium grade bark mix. Clay pots are useful for plants that get taller and top-heavy. Do not over-pot. Large plants with multiple growths can be divided leaving at least three canes per division . Keep dry for the first week to 10 days after repotting.
We offer several different types of potting medium. Here are direct links to what we believe to be some of the best potting mediums available for orchids: Orchids Limited bark mix, New Zealand sphagnum moss, coco husk, coco peat, sponge rock, charcoal, tree fern fiber and cork slabs for epiphytic plants.
