Within the genus Odontoglossum it is possible to recognize about 300 species of orchids originating from central-southern America. Today, there are numerous hybrid varieties of the orchid Odontoglossum, created following the pollination of different species of orchid. They are epiphytic orchids, with long ribbon-like leaves and thin and slender roots compared to common orchids. The flower stems are pendulous or upright and formed from a minimum of 5 to a maximum of 20 flowers. Generally, flowering lasts for several weeks. Over time, the plant becomes more and more resistant as the years go by and even the flowers tend to last longer. These are particularly beautiful and of great visual impact. Mottled and colored, with a variable lip and usually smaller than the petals.


These orchids like bright locations, but far from the sun rays that could cause the burning of the leaves and consequently compromise the general development of the plant; even excessive lighting could cause them to turn yellow quickly. In summer they can be placed outside, in a semi-shady position, preferring well-ventilated places. In winter, they should be kept indoors or in a temperate greenhouse, where the temperature is still above 15 ° C.


Water the plant abundantly, keeping the substratum partially humid, but avoid soaking the soil and leaving the roots in direct contact with the water; it is advisable to place the pot in a container filled with expanded clay, so that the water of the watering can drain freely from the pot, in winter drastically decrease the watering, avoiding however that the soil dries completely. Every 15-20 days, in the spring and summer period, add fertilizer for orchids to the water used for watering, using a dose equal to half the dose recommended on the package.


The odontoglossum they have more delicate roots than many other species of orchids, therefore we recommend a slightly lighter and looser substrate of cotlivation, use a mixture of bark and sphagnum, with added leaf mold. If the plants show stunted growth and lack of flowering it is advisable to repot them in larger containers.


The multiplication of this orchid takes place by dividing the clumps, immediately placing the new plants in a single container, preferably at the beginning of the spring season.

Odontoglossum: Pests and diseases

This orchid can sometimes be attacked by aphids which affect the plant's flowers and leaves by sucking its sap. The plant should be treated with specific pesticide products. Another pest harmful to our orchid is the cochineal that behaves in a very similar way and weakens the plant by depriving it of sap. It is important to increase the humidity of the environment and rub the leaves with a cotton pad soaked in alcohol to manually remove the parasites. Another problem, excessive watering. When this happens it is possible that water stagnations and radical rots develop which are particularly harmful for the growth of our orchid. Pay attention to watering according to the specific cultivation requirements of the plant.
