About this deal
Dendrobium orchids must be by bright light indoors. They require a lot of light but not direct sunlight. Choose, if possible, a south-facing window, perhaps slightly shaded. This light will emulate the bright, partial sun that the dendrobium orchid receives in nature.
You should also aim to mist it once or twice a day, to replicate the humidity of its natural habitat. The name ‘Dendrobium’ is derived from the Ancient Greek words for tree, ‘Dendron’, and life, ‘Bios’, and refers to the fact that these orchids are often found growing on tree branches in their natural habitat. 3 Dendrobium spectabile.

Maintain root mass, pot in orchid medium, and water after a week. Keikis can also be propagated when roots develop. Dendrobium Orchid Varieties Give a slight short rest (dry) when growth is finished. Keep barely moist until growth starts again. During summer, the sunlight intensity and temperatures are also at their peak. This means that water loss through transpiration and evaporation is increased. Also, your Dendrobium orchids need more water for growth and blooming.
Often, it’s as a result of temperature change. When winter arrives, many orchids start to flower, or it can be as simple as a change in temperature between night and day.”
4. Chemical-based pest control methods and their effectiveness on Orchids
While each growing environment is unique, and watering habits vary from person to person, it is generally a good idea to water about once per 7-10 days, when the mix gets dry. Too much watering leads to root rot, crown rot and other over watering problems like fungus gnat infestations. Do you prune an orchid? Plant Dendrobium orchids in a small pot, no more than 1 inch larger than the root system. Use an orchid-specific soil mixture, like fir bark, which is well-draining and allows for air perforation to prevent prolonged moisture exposure to roots. Growth Rate It lays eggs on flower spikes and new growth. Its larvae, which come in the form of white or yellowish caterpillars, also invade new growth and flowers, causing them to rot and collapse. The colour of the blooms ranges greatly depending on the variety – and includes red, purple, pink, yellow and white.
