How to Grow Pleione Orchid – Basic Care
The main growing conditions relate to moisture, during active growth, spring to summer Pleione Orchids like to be kept moist when in active growth, in dormancy, Fall to Winter they like to be able to dry out a little.
One of the major requirements is a good quality free draining potting mix, although Pleione Orchids do like moisture they do not like water logged conditions.
When growing in containers or pots use a deep one, this allows for the roots to have room in a cooler environment.
Planting Pleione Orchids
Simply fill the container with the soil mix and place the bulb on the surface, push in firmly making sure around one third is above the soil level. Water in well with a liquid seaweed fertilizer and leave then alone until spring.
Do not over water, if you experience very wet winters, check that the containers are draining freely, if not move to a protected position. Protect from frost and snow as well.
As new growth emerges you can water as needed, but do not overdo it.
Pleiones are used to a fairly rich source of food, so liquid fertilizer high in potash is an excellent choice once theta begin growth. Once a month from spring to summer. As with all fertilizers, water before using, avoid applying on hot days and avoid watering the foliage.
Avoid slow release or pelletised fertilizer as these can burn the bulbs.
Watering Pleione Orchids
These are orchids that require a dry winter, they do not tolerate a cold wet winter.
Commence watering in spring and continue through summer.
If you look carefully you may see some little bulbs growing on top of the old bulbs, remember that the pseudo bulbs will die and replace themselves so we need to re-pot every few years,
Again dormancy is the best time, remove the plant from the container and gently remove the soil from the bulb and roots. Last years flowering bulb will be dead, however the new growth buds will be evident.
The old bulbs can be trimmed away, retain as much of the root system as possible, trimming any dead or damaged portions, and you are ready to replant.
