Chysis bractescens is an untidy plant to grow, and if grown upright will continually strive to turn itself the other way. Eventually the pseudobulbs grow out at all angles. Taking a closer look at this plant, it will be found that the heavy, club-shaped pseudobulbs are wasted at the base; they grow from a considerably thick, strong rhizome and swell out as they mature, consequently becoming top-heavy. Even when accommodated in an open basket this plant will look decidedly uncomfortable, and the best answer is to grow it in a pendent position on a piece of bark.
The plant is removed from the basket in the usual way, and cleaned of its bark compost. The bare-rooted plant is then placed on the raft with a pad of ostnunda fibre, into which the roots have been folded, between the plant and the wood.
Ideally the plant should be left with at least four pseudobulbs, including those in leaf, on the main plant. The excess pseudobulbs can be removed by slicing them from the plant with a sharp knife. The cut should he made downward to sever the rhizome.
Although such a plant can be left to its own devices, sooner or later the job of repotting must be attempted, and the longer the plant has been left the harder this becomes. Our Stanhopea wardii has a number of pseudobulbs which are in an upright position within the basket, and two fully mature pseudobulbs which have grown at right angles outside of the pot.
In order to remove the plant without harming it, it will be necessary to cut away the basket around the area where the pseudobulbs have grown. Having done this the plant is divided into three pieces, two flowering size divisions and a couple of leafless backbulbs which can be propagated from if wished.
Monopodial orchids can also be propagated by various means, although it is not quite so easy, and usually comes about as a result of damage to the growing centre. Otherwise, with vandas and the like, only after several years' growth is there a chance of propagating. l'halacnopsis are unique in the orchid family, and will propagate From the old flowering sterns.
