Orchids are a singular group ofplants with gorgeous bloomsthat have prompt superfans and appreciation societies . However , if you require to make more of a favorite variety , how to propagate orchidaceous plant is a picayune different than propagating other houseplant . You ca n’t just lop a film editing and stick it in a pot of rooting medium or glass of piss . Orchids take more work and the technique to use depends on their growing pattern . This pathfinder covers the two main propagation method : keikis and division .

Types of Orchids to Propagate
“ There are over 30,000 naturally occur mintage [ of orchids ] and around 115,000 hybrid that have been read , ” says Justin Kondrat , spark advance plantsman for the Smithsonian Garden Orchid Collection in Suitland , Maryland . All those orchids go down into two general ontogeny patterns , and you need to bed an orchidaceous plant ’s growth rule before you pass around it .
Monopodial Orchids
“ These orchidaceous plant farm on a central stem that does n’t branch out , ” Kondrat articulate . ” They grow flower spike and aerial roots from that main prow , specifically at the distributor point where leave-taking get together the stem . genus Phalaenopsis , ormoth orchids , fall into this category , as do vanda orchids . ”
“ A monopodial orchid reproduces by forming a baby orchidaceous plant works called akeikiat its base or on flower spikesafter they ’ve bloomed , ” Kondrat says . Keiki is a Hawaiian word that means baby . To propagate the orchidaceous plant , remove this baby orchid and put it in its own pot .
Encourage monopodial orchids to make a keiki with a liquid plant internal secretion called keiki cloning library paste . “ Scar the orchidaceous plant stem near its base or on the heyday spike and put keiki paste on it , ” Kondrat say . “ It will trigger the orchid to bring forth a keiki . ”

Sympodial Orchids
These orchids grow fresh industrial plant from a rhizome or incandescent lamp . Cattleyas and oncidiums come down into this orchidaceous plant category . They commonly do n’t make a keiki . Their rootstalk make a thickened domain call apseudobulb , where new plant shoot develop , sort oflike an fleur-de-lis .
“ You propagate these orchids bydivision like you would with your typical perennial , ” Kondrat says . Some sympodial orchids , like dendrobium , make keikis , but dividing its rhizomes is the most common way to make fresh plants .
When to Propagate Orchids
Propagate an orchid after it has finished bloom . If a keiki forms earlier on a monopodial orchid , you could dilute it off while the plant is blossom and put it in its own pot .
Propagate a sympodial orchid when the works outgrows its potbelly . When you see pseudobulb and Modern roots and shoot advertise up around the main plant , it ’s fourth dimension to divide the orchidaceous plant . “ You never require to divide a plant that is n’t salubrious and thriving , ” Kondrat enjoin .
If your orchid looks less than healthy , feed it and get it level-headed before you cut it into pieces , which is essentially what you ’re doing when you dissever the plant . “ Dividing an orchidaceous plant disturb it , so do it in conjunction withrepotting it , ” Kondrat articulate .

How to Propagate Orchids
Here ’s how to make new plant from your mature orchid .
Propagation by Keiki
Once a keiki has three or four roots , it ’s quick to be cut off the parent plant life . expend a clean andsharp newspaper clipping toollike snips or a knife to cut back the keiki from the blossom spindle . send the keiki in a little pot with orchid growing medium . If it ’s a small keiki , heap it in sphagnum moss , Kondrat says . Keep the average or moss moist , but do n’t overwater .
Propagation by Division
mildly off the orchid from its pot . face at the plant to identify the pseudobulbs that will make good divisions . They should have Modern leafage or shoot growing out of them and some root begin to form . A good - sized division has three to five pseudobulb , depend on the type of orchidaceous plant . Cut the plant aside with a piercing cut putz , separating the divisions . grade each division in a small potwith sphagnum moss and keep it moist , but do n’t overwater , Konrat advises .
How to Fertilize Keikis or Divisions
look a month before fertilizing the newly potted keiki or division . Konrat say , “ I would give them a piffling clock time to get back , just so they can get themselves anchored . Once the roots elongate , they ’ll have more surface country to engross nutrient . ” Konrat advocate using a fertiliser word for orchids with anN - P - K food ratioof 20 - 20 - 20 , diluted to 20 percent of the recommend amount .
Kondrat also recommends using dilute fertilizer throughout an orchid ’s lifespan , not just when starting a new plant . “ When you think about how an orchidaceous plant grows in the native environment , it ’s always getting a little bit of food for thought here and there when a skirt flies by and poops on it or when poppycock drop from the barque on the torso that it ’s growing on , ” Kondrat enunciate . Duplicate that by giving your orchid fallible fertiliser always during outpouring , summer , and early fall , he says .
