Dendrobium orchids are one of the easier orchid varieties to grow. They make a wonderful flowering houseplant that adds the perfect amount of color to any room, desktop, or window sill. Dendrobium orchids add a stylish note to any space.
DENDROBIUM ORCHID CARE
We recommend a fairly high light intensity for dendrobium orchids. Generally, cattleya light (2000-3000 foot-candles) is most suitable. If they are grown in the home, a brightly lit south or east light exposure is best.
Evergreen-type dendrobiums require heavy watering in the growing season (spring and summer). As the new growth matures by fall, watering should be somewhat curtailed but not so much as to let the canes shrivel back.
Adjust humidity by seasons. Higher in the summer growing months, around 50-70%, and lower in the winter, around 40-50%.
Most dendrobium orchids do well in an intermediate temperature zone. Day temps should be in the 70-90 degree range, and night temps should be in the 55-62 degree range.
Dendrobium orchids require heavy feeding during their growth period, in general. But as with watering, feeding should be curtailed during the fall and the winter months.
POTTING DENDROBIUM ORCHIDS
Repotting at the proper time is most important. For dendrobiums, spring is the best time to repot. Make sure that the new growth (with root action) has started before transplanting. Dendrobiums like to be somewhat root-bound. Allow minimal space for new growth. Use a coarse fir bark that allows perfect drainage.
OTHER ORCHID SUGGESTIONS
PHALAENOPSIS – Phalaenopsis is one of the easiest orchids to grow, and the blooms can last for many months. They are an excellent choice for a beginner orchid parent. Phalaenopsis orchids’ biggest threat is the risk of rot. Be sure to keep the crown of the plants dry, especially at night. Also, groom your plants constantly, remove all old leaves and flowers, and check for bugs. These orchids are an advantageous plant for the beginner due to their easy culture.
NOBILE DENDROBIUM ORCHIDS – The Nobile Dendrobium orchid is a genus of the Dendrobium orchids. Dendrobiums are native to the far east and grow epiphytically on tree branches from the warm lowlands to the cool highlands up to 4000 feet. Kept dry, they can survive in winter down to 35 degrees. Most blooming occurs from February to April.
PAPHIOPEDILUM ORCHIDS – Paphiopedilums or “paphs” are very easy to grow. They remain compact in their growth habit and have attractive foliage with long-lasting flowers in a wide range of colors. Although classed as terrestrials, they do not really grow in the ground. Rather, they grow in a layer of decaying vegetation found on the forest floor. It is helpful to know where an orchid grows in nature to more easily duplicate these conditions in our home or greenhouse.
