IMPORTANT SPECIFIC CULTIVATION INSTRUCTIONS FOR PLEIONE
Temperature ;
Most species and hybrids are frost resistant and withstand temperatures between
minus 5 and plus 28 °C Except from a few autumn flowering species they do need
a cold winter rest at temp’s between 0 and 5 °C for two to three months to
get good results . They do not stand heat in summer , supply enough moisture at
warm temp’s and if greenhouses get too warm , put them in a cool shady place
outdoors .
Light
; One may give them full sunlight between November and February , and relatively
cool shady conditions in growing stage, morning sun is beneficial though.
Humidity ;
Critical is keeping plants dry in cold rest periods. As those plants are
affected by monsoon rains in nature ,
they need abundant watering in peak summer . Watering need to be
increased gradually as new growths start to develop . During growing season
plants may not become dry , as the thin unbranched roots may be lost and will
not be replaced afterwards !
Compost ;
Very tolerant , most species do well with a compost of fine graded bark , pumice
gravel or perlite and freshly fallen and cut
oak and beech- leaves, more or less equal parts . Providing good drainage
, one can use some moss or sphagnum to make it more water retentive .A cover of
some kind of living moss has proved very beneficial for sensitive species .
Repotting ;
Yearly, or each two years , in winter or in February latest , just before
growing starts .
Water
quality ;
Rainwater is advisable , otherwise good quality tap water low salt and
chlorine poor .Good oxygenic water is essential .
Fertiliser ;
Not before new roots are well developed, somewhere in June for most
species. One may use slow release grains up to 10 grains for strong growing
hybrids or a good quality chemical fertiliser dissolved in spraying water .Good
results are achieved with adding
some fully decomposed manure to the potting mixes as well .
