Native to eastern and southeastern Asia, Dendrobium Orchids are flowering tropical plants, usually grown as houseplants or in greenhouses. Dendrobium Orchids come in a variety of colors and sizes and make great starter plants for novice or beginner orchid growers.

Dendrobium orchid flowers grow in clusters called “sprays” along well-ripened branches. The plants produce smooth leathery petals with intricate designs and varying colored patterns.

A single Dendrobium orchid plant can generate hundreds of three-inch flowers. Well-maintained plants are capable of holding their blossoms for as many as two full months. This guide to caring for and maintaining Dendrobium orchids will help plant lovers successfully grow and enjoy these Asian wonders.

Although growing Dendrobium orchids in greenhouses is easier than growing them in the home, these orchids make great flowering houseplants when growers meet their main growing requirements. A bit of strategic placement and in some cases rearranging to different areas of the home may be necessary at times, however, successfully bringing Dendrobium orchids to bloom is worth the extra effort.

Provide Sufficient Lighting to Promote Growth

Granted greenhouses are not being used the first thing Dendrobium orchid growers should consider is where in the home to place the plants. Dendrobium orchids need plenty of light but not too much direct sunshine. Although overhead lighting can aid Dendrobium lighting needs it is best to provide these plants a source of outdoor lighting as well.

Whenever possible, situate Dendrobium orchid houseplants where they can receive filtered sunlight. South or west windows usually work best at providing sufficient lighting and preventing overheating. When choosing to set plants in windows with direct sunlight, use sheer curtains or other shading devices to reduce sun exposure especially during hot midday afternoons.

Dendrobium orchid leaves should range from light green to deep green. The leaves should be stout, plump, and despite their curviness, they should be erect as opposed to hanging or leaning. Soft dark leaves indicate plant lighting is insufficient. Provide more overhead lighting or move plants to brighter locations as necessary. Just remember to avoid too much direct sunlight.

Humidity Levels Best for Dendrobium Orchids

Dendrobium orchids thrive on humidity and love weather conditions that consist of relative humidity levels reaching at least fifty percent of their surrounding temperatures.
