There ’s no doubtfulness about it – orchid are one of Mother Nature ’s sterling tease . From the minute they were first document , plantsman have described the suggestive form of orchid flowers and the intoxicating smell .
Whatever you might think of these claims , the fact that Orchidaceae is the secondly big house of flowering plant life in the world ( after Asteraceae ) with some 28,000 mintage across 763 genera should tell you something .
In fact , orchid are incredibly popular as houseplants , despite involve a moment of extra concern . This bring up a plebeian question regarding indoor orchidaceous plant care .
orchid , as with all potted plants , require to be repot occasionally . However , your orchid may have produce aery root , which makes repotting a little snatch more hard .
lease ’s take a moment to canvass the phenomenon of airy roots and the step needed to repot an orchid that has them successfully .
How To Repot An Orchid With Air Roots?
Before we discuss repotting , it ’s crucial to realise what aeriform roots are . Afterward , we ’ll discourse the repotting cognitive process in more deepness .
Just What Are Aerial Roots?
There are two cosmopolitan type of orchids :
Terrestrial orchids grow exclusively on the ground and do n’t develop aerial origin . However , epiphytic orchids are a spot different .
Epiphytic is a term that translates to “ upon industrial plant ” and has two subcategories .
semiepiphyte commence as terrestrial plants but climb when they find a support plant and become epiphytic .
Holo - epiphytic ( often just call epiphytic ) industrial plant never tinge the earth and rely completely upon the host plant ( called a phorophyte ) for support .
Most orchids are holo - epiphytic , and this is why they formulate aerial stem .
Unlike parasitic plant , which burrow into the host works , epiphytes have get wind to describe wet and nutrient directly out of the air ( or water , in some slip ) and only interact with the host works by clinging onto it for funding .
Thus , those peculiar tune source from your orchidaceous plant are in reality serving an important function .
When Should Orchids Be Repotted?
Now that you know what aerial roots are , we can let you in on a footling secret regarding orchid .
Because these are ( mostly ) holo - epiphytic plants , they ’re not adapted to life in the soil . This means they tend to react much more powerfully when the nutrients dissipate from the soil over metre .
Many growers use a soil - free blend that make much better with orchids ( because it contains bark and other substance the plant is more at home with ) , but even these mixing can lose their nutrient over metre .
Fertilizing helps to some extent , but the trade - off is add mineral table salt to the potting medium , finally harming the plant .
As a effect of trying to put orchids into an environment they ’re not well suitable for . They ’ll examine to spread out their roots in search of a more compatible environs .
This means orchids can quickly outgrow their container or station out aerial root .
Between this attempt to escape captivity and the motive to ensure the plant life is really get enough nutrient from its soil , you will need to repot every 2 years .
However , if you see root poking from the soil , this is a star sign the industrial plant needs a bigger pot , and you should n’t await to repot .
If possible , aim to repot during the summertime when the plant is at its healthiest growth to minimize transplanting shock .
Repotting An Orchid With Air Roots: Step-by-Step Guide
Repotting an orchid with air travel tooth root is a routine more complicated than repotting tellurian plants , although the extra steps involved are n’t specially surd .
Here ’s everything you want to recognise to repot your orchidaceous plant every metre successfully .
Step 1: Remove The Container
Before repotting , irrigate your orchid to moisten the soil and loosen it up a little . This can also help your orchid ’s theme to relax a little .
If you have a fragile , flat utensil ( such as a popsicle stick ) , you’re able to run this around the inner edge of the hatful to serve loosen the dirt away from the container wall .
Be heedful not to hurt or damage any root while doing this step .
With the plant loosened , there are two way to move out the pot .
The first method is to gently grab the orchidaceous plant by its stems near the base of the industrial plant ( never seize by the aeriform roots or leaf ! ) and cautiously wriggle it out of the container .
The 2d method acting involves laying the industrial plant on its side , being trusted not to damage the plant .
While holding onto the base of the plant , so it does n’t move , take your shear or another object and give the bottom of the pot a steadfast tap or two , then slue the pot off .
Note that soil - free potting mixes will usually make out out much easier than soil .
Step 2: Remove All Old Soil And Soak
Gently pick up the works near the base of the stems and slowly shake up off any loose potting medium .
Using some lovesome ( not hot ) distilled piddle , carefully isolate sections of root ( include aerial roots ) from the leaves and crown and rinse off off any stay potting culture medium .
This has the added welfare of making the roots more pliable .
If necessary , you’re able to soak the roots themselves in warm water for up to 20 min to get any stubborn detritus to come off .
If the crown or leaf get soaked , lightly dab away the wet using tissues or a soft newspaper towel , but obviate rubbing or other coarse movements .
Step 3: Examine And Treat The Roots
Healthy roots should be whitened to off - livid , while nauseous roots tend to be dark-brown to nigrify .
Using incisive , sterile shears , mildly prune away any diseased roots and those that have died or dried out ( considering you just provide spate of water , any dried - out roots are obviously no longer functioning properly ) .
Be certain to desex your shears after each cut of meat to preclude the risk of cross - contamination or infection from any airborne pathogens .
Grab a spray bottle of 3 % H peroxide and thoroughly spray the root to kill likely pathogen . Then admit the peroxide to vaporise course .
Step 4: Repotting
Now that your orchid has had a exhaustive test , has only good for you roots , and was sterilized against possible disease , it ’s finally time to repot .
If the orchid was becoming rootbound , calibrate to a new container 2 ” inch larger .
Otherwise , you ’ll require to reuse the old container ( or a new one of the same size if you get word etymon hogwash or other disease on the source ) .
append invigorated potting sensitive to the container , assure it ’s overnice and loose , then sit the orchid in the pot .
Gently add more soil , propagate the roots a little as you go , so they have more elbow room to expand until the pot is completely full .
observe that some or all of the aerial base may cease up in the potting medium by the clock time you ’re done , but you do n’t want to immerse the plant itself deeply than or was antecedently to avoid the risk of bow or crown rot .
