orchid bloom at various times throughout the year depending on the species and growing atmospheric condition . Cattleyas and genus Phalaenopsis , for instance , run to bloom in the spring while cymbidium and oncidiums generally flower in the wintertime . The blossom stems will dry up and become brown after the flowers fall , at which prison term they can be switch off off . Where the stem or spike should be trim depends on the type , wellness and maturity of the orchid .
Orchids in General
The general rule of thumb when cutting spent heyday stems or spikes from orchidaceous plant is to cut them off at the base . This should be done on cattleyas , cymbidium , dendrobiums , Epidendrum , paphiopedilums , genus Phragmipedium and vanda . After these orchidaceous plant have flower , they will not produce any more bloom on the bloom stiletto heel . There is no need to bequeath the spike heel on the orchidaceous plant until the whole thing turn brown . It can be removed as soon as the flowers throw and the gratuity of the spike reverse brown . As long as the orchidaceous plant is healthy and growing stipulation are correct , it will put out a new spindle for the next efflorescence time of year .
Phalaenopsis Orchids
Phalaenopsis orchid produce multiple heyday on the same stiletto heel . Most type of phalaenopsis can have the ear trim down back to just above a level-headed growth node when the flowers drop and the spike begin to turn brown . increase nodes are raised triangular flaps of industrial plant tissue on the flower spike . The healthy phal will grow young spike from the ontogeny thickening and flower from those . Small , unseasoned phals that are less than 1 invertebrate foot tall or those that are not growing smartly should not be allowed to endeavor to rebloom . Their peak spike should be removed at the base of the spike as soon as the blooms knock off . Some orchid growers always cut the spike off at the base to prevent reblooming regardless of the size , health or maturity of the orchid . blossom saps energy from the works , ensue in slower plant growth .
Amboninsis, Cornu-cervi and Violacia Descendants
Phalaenopsis orchid that are descendant of amboninsis , cornu - cervi , violacia and similar orchids blossom continuously from the same flower spike . The spikes on these phals should not be cut unless they grow too long . If the spike has grown so long that it has become unsightly , it can be cut back to just above a maturation node . It can also be removed at the al-Qa’ida in the leap to give the orchidaceous plant a rest and advance newfangled plant growing .
Oncidiums (Psychopsis)
Some type of oncidiums ( psychopsis ) , such as papilio or butterfly stroke orchid , should not have the flower spikes abridge when the bloom unload . These orchids will flower on the same spike for years . The spike can get to 2 feet long . The flower spindle should be bump off at the basis when the orchid is repot to reduce stress while it becomes re - established . apply a good potting culture medium that demote down very slowly to permit as much clock time as potential between repottings .
