Pleione like good light during the growing season and can be left out doors during the summer or grown close to the glass if grown indoors. During the winter resting period they can be placed on a shelf in the greenhouse or a cool room with diffused light.
Pleione like moist compost during the growing season which is between February and October, during this time they should be watered every week (starting sparingly until established) using clean fresh water. From October through the following April the compost should be allowed to dry out completely.
As mentioned earlier Pleione are deciduous and will require a rest during the winter.
The plants are moderate feeders and a balanced plant food can be applied from April to August at 1/4 the pack recommendation given every third watering. During late August and September you should change to a higher potash feed (again at 1/4 strength) which will encourage the new bulbs to ripen in readiness for the rest period. Feeding should cease by October and no more should be given until the following spring (March) at which time normal feeding can resume.
Re-potting schedule and compost
Pleione are naturally semi epiphytic and can be grown either in a pot or a shallow pan. The compost mix used should consist of equal parts loam, sphagnum moss and medium grade orchid compost, this will provide good drainage and moisture retentiveness.
Pleione should be re potted every year in fresh compost either before flowering or just after, this depends on the variety grown but generally around January.
The rounded bulbs do not need burying in the compost but should be allowed to rest on the surface of it or at the most just have the very base pushed slightly in to it for stability. Because they will have no roots at this time they may need some for of support until roots are established in the compost.
Here are a few commonly grown species, if in doubt grow them in cool conditions rather than alpine.
Pleiones produce numerous small bulbs around the base of the old bulb or around the 'scar' formed when the leaves fall, these should be potted up in trays and will be flowering size by the second year.
