Coelogyne dayana [Rchb.f]Rolfe 1864

Intro: Coelogyne dayana is native to the island of Borneo. This beautiful species has tapered conical pseudobulbs that reach 7 inches in size. The bifoliate, long, stiff, pleated leaves are about 2 feet in length. The flower spikes emerge several times per year and can be up to three feet or more in length. The flowers have a nice woody-nutmeg fragrance. This is a spectacular species as the spikes cascade down all around the pot. **Click on the highlighted text for direct links to product pages** Light: Medium light as for Phalaenopsis to Cattleyas Bright defused light is best. An east window will be good light in an average home. This plant will also do well under high pressure sodium fixtures at a distance of 4 feet away 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. Temperature: Intermediate to warm with winter days being 70 to 80 degrees Fahrenheit and winter night time lows being between 58 and 64 degrees. Summer temps can be a few degrees warmer. 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. Please click on the underlined text f 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 approaches dryness but do not allow the mix to become completely dry between watering. This plant has hairy roots and requires frequent watering to do well. The pseudobulbs are naturally furrowed but if the mix is allowed to dry to much between watering the bulbs will begin to shrivel. If this does happen simply keep moist and the bulbs will re-hydrate. 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. Or use 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 species is quite amazing as mature plants can bloom 5 or 6 times per year! The inch and a half flowers are colored in light straw yellow, tan and chocolate. They have a fragrance reminiscent of a tropical wood with a hint of nutmeg. The flowers are not long lasting being in bloom for 2-3 weeks. They are well worth growing as a plant can produce several spikes that are slightly behind one another giving one several weeks of bloom. The flower spike are pendulous in nature and develop rather quickly. It is important that while flowering the plant be kept slightly more moist at the roots. Repotting: The best mix we have found is New Zealand sphagnum moss. The plants grow very well in this medium as they like moisture. Repot in the spring to early summer months after flowering. Plastic pots are best. 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, osmunda fiber and cork slabs for epiphytic plants.
