Flowering
From Late Winter TO Early Spring
The natural bloom season is during the spring, when your plants should be indoors and available for display.
Planting young plants
From Early Spring TO Late Winter
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.
Propagation
From Late Spring TO Late Spring
Propagation is achieved from seed or by the cutting of the base clump of the plant. The large flowers occur in spring. Also, flower stem node propagation brings success. Where after flowering, the scape is either laid whole or in sections on a medium such as Sphagnum moss or stood in a container of water. Plantlets emerge from the nodes, and when large enough are removed and potted up.
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.
