Routine pruning is not a necessary part oforchid aid ; however , there are times when a piffling cutting back is beneficial to the plant . Knowing how to prune an orchidaceous plant is useful when you want to boost the plant to rebloom , prepare it for repotting , or get rid of morbid leaf , for illustration . Different pruning proficiency are want for the different type of orchids . This guide explains what you ask to sleep with about crop different type of orchids and provides expert tips on when and how to make the cuts .

Types of Orchids
All orchid fall into one of two general types based on their growth pattern , and you involve to know an orchidaceous plant ’s growth radiation pattern to prune it correctly .
Monopodial orchidsgrow on a single stem that grows straight up and does not ramify out . These orchidaceous plant produce efflorescence spikes , leaves , and aerial roots from a unmarried growth point on their stems . genus Phalaenopsis , ormoth orchid , fall down into this category , as do vanda orchids .
Sympodial orchidsgrow from a rootstock or bulb and have multiple tooth root organization . Cattleyas and oncidiumsfall into this orchidaceous plant category . They march across their pots , growing horizontally and producing new roots , leaves , and stems at multiple growth points along a undivided stem , known as a rhizome .

No matter the eccentric of orchidaceous plant , go ignitor on pruning . While some plants love strong-growing pruning because it prompt vigorous regrowth , that ’s not the sheath with orchidaceous plant .
“ [ Orchids ] broadly speaking like a trimming , not a prune , ” says Justin Kondrat , a horticulturist who cares for the Smithsonian ’s large and diverse orchid collection .
Pruning Flowers
Amonopodial orchid can rebloomon the same angry walk if you trim it while the stalk is still unripe and alive . Once a monopodial orchidaceous plant has bloomed and the flowers have return off , cut the still - green stalk half an inch above the second or third knob on the stalk .
“ Give it a little track to take out the part of the stalk where the flush were once attached , ” Kondrat say . “ you could trigger the plant life to develop a new stalk from the knob that will blossom , ” Kondrat says . “ Pruning like this draw an orchid rebloom in eight to 12 week about 50 percent of the prison term . ”
The other way to machinate a monopodial for reblooming is to trim off a peak stiletto heel completely if it has bloomed and turned completely brownish . Trimming off the old , bushed shuck encourages the plant to redirect water and nutrients to fresh growing , permit the orchidaceous plant to develop a new flower stalk within several months .
Sympodial orchids can not rebloom on the same efflorescence stalking . They only bloom on new growth from the roots .
Do n’t cut goodly green leaves off an orchidaceous plant after it blooms . It needs those leaves . you’re able to dress pass blossom off a plant , though .
“ leaf are the solar panels of an orchidaceous plant . allow them on the flora so they can feast it and doctor its energy after bloom . ”

Pruning to Propagate
A monopodial orchid grows a new plant by producing a baby orchidaceous plant plant called akeikiat its base or on flower stalksafter the plant has bloomed , Kondrat says . dress off a keiki once it has roots andput it in a potto start a new orchid .
Sympodial orchid must bepropagated by dividing them , not pruning or trimming them .
Pruning Roots
All orchid — monopodial and sympodial — need to berepotted when they outgrow their commode . “ I commend repotting your orchidaceous plant every two years , ” Kondrat say .
Trim them when you repot them . After you draw the plant out of its old pot , examine the plant and its roots . cut back off dead roots , bulbs , stems , and canes . A goodly , living orchid origin is blanched , Kondrat says , while a dead root looks like brown string .
Pruning Old or Diseased Leaves
If a folio on your orchid look unhealthy , rationalize it off . “ That prevents the pathogens that caused the morbid part from spreading to the rest of the plant life , ” Kondrat says .
What does an unhealthful orchid foliage expression like ? It may be yellowed , have dark musca volitans or sunken lesion , Kondrat says . After you reduce off the damaged leafage , inspect the plant to see if there ’s a larger job . It may havemealybugsor a fungal outcome that requires treatment .
orchidaceous plant naturally shed old foliage . If the bottom leaves of a monopodial orchid turn yellow , the plant life is believably prepare to cut down them because the leaves are nearing the end of their lifespan . They ’re drain of nutrients because they ’ve done their line , so you could trim them off .
For sympodial orchids , you may need to trim off the oldest pseudobulb and foliage after its nutritionary stores are spent . The orchidaceous plant will finally shed these older parts on its own , but crop them realize the industrial plant look tidier and speeds up its natural growth process .
