Odontoglossum
Odontoglossum Orchid
Odontoglossum orchids grow under fairly low light levels. In the home, they do best in a North or North-East facing window, never in the middle of a room as they need to be close to light. In the greenhouse, they need shade from late winter until the end of summer. Shade-netting, like Rokolene 60%, should be fastened to the outside of the greenhouse.

Odontoglossum
Odontoglossum orchids grow under fairly low light levels. In the home, they do best in a North or North-East facing window, never in the middle of a room as they need to be close to light. In the greenhouse, they need shade from late winter until the end of summer. Shade-netting, like Rokolene 60%, should be fastened to the outside of the greenhouse.
Flowering
From Early Spring TO Late Winter
Odontoglossum produces flowers that last about three months (sometimes even longer) at any time of the year. Once the flowers have faded, cut the flowering stalk back to just above the second node (joint) visible beneath the spent flowers. A new flowering side shoot may develop.
Planting young plants
From Early Spring TO Late Winter
Sometimes small plantlets (keiki) appear from the nodes on the flower stems. Detach the plantlets when they have developed several good roots and pot them up in orchid compost. Water them sparingly at first, but mist them daily. Always use a proprietary orchid compost. Ensure good light levels in winter, as these are essential to encourage flowering. An east- or west-facing window would be ideal. Move to a shadier spot in summer and protect from direct sunshine.
Flowering
From Early Spring TO Late Winter
Many orchids do not have a flowering season and flowers may be produced at any time if the right conditions are being met. Terrestrial orchids grown outdoors will mostly flower in the summer months. Flowers can last for several months.
Planting young plants
From Early Autumn TO Late Autumn
Sometimes small plantlets (keiki) appear from the nodes on the flower stems. Detach the plantlets when they have developed several good roots and pot them up in orchid compost. Water them sparingly at first, but mist them daily. Always use a proprietary orchid compost. Ensure good light levels in winter, as these are essential to encourage flowering. An east- or west-facing window would be ideal. Move to a shadier spot in summer and protect from direct sunshine. When planting terrestrial orchids outdoors, plant in semi-shade, no direct sun at midday. A very suitable place would also be on the north side of a building. Most orchids are woodland plants and therefore prefer cool sites, which do not become too dry and hot during summer. Places where ferns thrive are also suitable for. Don’t plant your orchids close to trees or big shrubs because their roots are effective competition for water and nutrients! Autumn is the best season for planting. Spread out the roots in the upper 10 cm (4 inches) of the soil, the rhizome 2-3 cm (1 inch) below the surface, shoot buds upwards. Fill in the remaining substrate without compressing it, and water thoroughly.
