Can Oncidiums grow indoors?
1 The most common oncidium orchids grow well under normal indoor conditions. They have large pseudobulbs (a bulbous thickened area of the stem) that come up from a mass of thin white roots. The large leaves can get up to 2 feet long and emerge from the pseudobulbs. Oncidiums typically flower in the fall.
Is Oncidium easy to grow?
Oncidium orchids are fast-growing and easy to cultivate. Well cared for plants put out new bulbs all the time, forming large clumps. Simply break them apart into divisions of three or so. You may not even need tools to do it!
How do you care for an Oncidium orchid?
A good general rule is that Oncidiums with thicker roots and leaves will not need to be watered as frequently as those with thinner leaves. Plants should be watered thoroughly with lukewarm to room temperature water every two to ten days, when the planting media is half dry.
How much sun do Oncidium orchids need?
Most will thrive with one to several hours of sun a day. Generally, thicker leaved plants, such as “mule-ear” and “equitant” oncidiums, can stand more light. In a greenhouse, 20 to 60 percent shade is required, or about 2,000 to 6,000 foot-candles, depending on the plants.
How fast do Oncidiums grow?
Depending on the variety the flowering season can be at any time of year, but is generally heaviest in the fall and spring. Many hybrids can bloom 2-3 times per year. In order to initiate the flower spikes, it is important to grow the plant in an area where the night temperatures fall below 18° C.
Do Oncidium lose their leaves?
This is entirely normal and is not a cause for concern. The orchid in the picture, an Oncidium, is doing just that. After repotting it has chosen to shed the leaves on its oldest pseudobulb (often called a “back bulb”).
Do Oncidium spikes rebloom?
Oncidium flower spikes can produce many flowers. In fact, you may be surprised by the seeming relentless flower spikes that emerge, one after another. After blooming, the flowers will wither, turn brown and begin to drop.
How many times do Oncidium orchids bloom?
There is no ‘blooming season’ for Oncidiums – they bloom whenever a new growth matures which can be 1-2 times a year.
Can Oncidium orchids grow on trees?
Dancing Lady orchids are usually epiphytes, depending on the variety. This means that in the wild, they grow on trees by clinging to the bark. They can also sometimes grow on rocks.
