Dendrobium speciosum

Many orchids do not have a flowering season and flowers may be produced at any time if the right conditions are being met. 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.Terrestrial orchids grown outdoors will mostly flower in the summer months. Flowers can last for several months.

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.
