there are a lot of cultivars available, based on dendrobium nobile. flowering in nearly every color you want. the flowers are shown along the stem. the mother of those easy to care for orchids is native to india.
dendrobium nobile cultivars need high light with some morning and/or evening sun the year round. they should be protected from afternoon sun.
this orchid can be cultivated at room temperature during spring and summer and 10-16 °c/50-60 °f at its rest in fall/winter.
dendrobium nobile needs a special mix for epiphytic orchids which should contain some fir bark and peat moss. it’s not suitable for growing in regular potting soil. it should be repotted every 2-3 years, when it begins to outgrow the pot and the soil is going to break down.
in spring and summer it can be deep waterd, whats flowing out of the pot should be removed after a few minutes. wet legs can cause rotten roots. before adding water next let it become moderately dry.
if it’s actively growing or flowering a half diluted orchid fertilizer can be given monthly.
to increase humidity it can be placed near a humidity tank or be sprayed over with water. it has to be done in the morning so the that water can evaporate throughout the day. this gives the orchid some extra humidity and it can tolerate if the soil becomes a bit drier sometimes.
reblooming dendrobium nobile
in late autumn after its pseudo bulbs have fully matured, denrobium nobile needs a dormant rest to initiate flower buds. it now should be placed at 10-16 °c/50-60 °f. watering must be reduced, give only enough to prevent the orchid from shriveling (approx. every 2-3 weeks). a fertilizer must not be given.
when the buds are 1 cm/0.39 inch long, watering can be resumed and it can given back to its old location.
