RE: Sydney Rock Orchid

in #dendrobium6 years ago

They can be grown on a rock by sitting them on some orchid compost and propping them up with smaller rocks: they will eventually attach themselves to the main rock. They can also be affixed to a tree using an old stocking partially filled with orchid compost in which to anchor the roots - tie the orchid onto the tree with the ends of the stocking. Eventually it will adhere itself onto the bark. They can also grow in cut-up tree stumps. They can also be wired onto boards. If grown in pots, they need very well-drained orchid medium. They should not be planted directly into soil. Give them water, especially in summer, and some liquid fertiliser occasionally in spring and summer. They need sun to promote best flowering. The colour of the flowers can echo cream-coloured Clivia that appear at the same time, and also consorts well with the soft blue flowers of Salvia fallax. Propagate by removing rooted pieces from the clump. The main pest is the dendrobium beetle, which can ruin leaes, new shoots and flowers. Remove them by hand in the early evening. You can flick them into a container with some soapy water at the bottom.
