It ’s completely possible to originate this cool - weather veggie , also known as pak choi or by its botanic nameBrassica rapasubsp.chinensis , in a container !
The benefit of transplantation or direct - seeding bok choy in a bay window do n’t stop with simple distance delivery , either .
you could also more well cover the grow season by protect small mess of bok choy with dustup covers , for example .
It ’s simpler to handle insect pests and preclude diseases in a container , too .
But the biggest plus might be the increased control over bolting , which is a bok choy nurseryman ’s Public Enemy No . 1 .
When pak choi bolts , anthesis and going to seed before its time , it loses its flavor and becomes toughened and woody .
Container gardenerscan avoid the two chief causes of bolting – other heat waves and surprise bouts of freezing weather – but by bring their plants indoors for a brief spell .
Try that with a raise bed or vegetable patch !
Along with sell you on the virtue of this gardening option , I ’d like to share the tried - and - true garden practices that will aid you succeed with growing bok choy in container .
Here ’s what I ’ll cover :
What You’ll Learn
Choosing the Right Container
I ’ve seen people do just all right mature pak choi and other leafy brassicas in all sorts of pots , from coffee cans ( remember those ? ) to peanut butter jars , styrofoam cups , tea kettle , or even uncontaminating , juiceless ice cream cartons .
Any of those would work for you , too , as long as you clean them first and can figure out a fashion to add drain holes . Bok choy wish moist , well - enfeeble soil , and will languish if the growing medium is waterlogged or overly dry .
If you ’d like to plant in a more conventional container , be sure to find out one that has drain holes and that ’s made from a fabric that wo n’t dry out out too quickly .
You ’ll need a bay window that ’s at least eight to 10 inches in diam per plant life , and that ’s at least six in inscrutable for dwarf diversity , or eight to 10 column inch deep if you ’re design to farm standard cultivars to maturity .
When you aim to grow more than one plant life per pot , it should be wide enough to allow for the spread of each plant life plus a couple of inch between plants .
Some gardeners mistakenly believe they can plant anyvariety of veggie seedsquite close together in a container , but that ’s only true of bok choy if you plan to harvest it all at the microgreen stage , while it ’s still just an inch or so tall .
large seedlings need proficient atmosphere circulation to quash fungal diseases and grow quickly .
Also consider how crowing and heavy of a pot you are uncoerced to deal with . Some ceramic or concrete planters are quite unmanageable to move , which puddle it tough to wreak bok choy indoors to quash weather that ’s too spicy or too cold , if this is something that you go for to be able-bodied to do .
Even a vinyl radical planter or a grow bag can become super clayey once you fill it with soil .
Your best bet is going to be lightweight pots that are adult enough to hold three plants each at most , or openhanded metal tubs with a rolling flora stand placed beneath them that will allow you to move them around easily .
Once you ’ve settle on a container , choose the good grunge to go with it , and load ‘ er up . Here ’s how :
Preparing the Pot
Whether you ’re growing bok choy in a garden plot or a container , it prefers prolific , well - draining originate culture medium .
It ’s also important to fill containers with a potting mix that ’s sterilized , so you ’re not import bugs or soilborne disease pathogen .
Nature ’s Care Organic Potting Mix
Nature ’s Care Organic Potting Mix with Water Conserve from Miracle - Gro is a suited option . It’savailable in eight - quart bags from Home Depot .
Ordinary garden soil can also be too dense and may not have enough nutrient , not to mention the slightly acidulent to neutral pH of 6.0 to 7.5 that ’s required for quick - spring up , flavoursome pak choi .
beforehand of transplanting or verbatim seeding , fill the containers with the loose , fertile potting mix . Leave a disruption of an inch or two at the top of the Mary Jane to allow for easy memory access when lachrymation .
Then add your plants or seeds of choice , as we compensate below .
How to Sow
key a spot outdoors where you could tuck a container or two is easier than preparing a garden seam , but you ’ll still need a location that ’s partially shaded , and that deliver three to five hours of sun each day .
A protected deck might volunteer some shade , or a mature Sir Herbert Beerbohm Tree .
If you ’re planting more than one plant in a pot , use the space necessary listed onyour seed packetor transplantation label to calculate how much way you ’ll involve between plant , also taking into account whether you plan to clean them when they ’re mature or child sizing .
Learn more about bok choy space in our guidebook .
Bok choy grows well when nighttime temperatures are reliably high than 50 ° degree Fahrenheit , so wait to transplant or inseminate seeds alfresco a couple of week past your average last frost date .
Also be indisputable you ’ll have enough time for them to ripen before raging weather arrives and the plant bolt , which can destroy the smack and make the grain woody .
See our guide on preventing bok choy boltingfor more instructions on that important facial expression of growing this vegetable in containers .
To direct seed into your container , sow in the seeds a fourth part - column inch recondite . Keep the soil in the pot moist but not mucky until sprouting . This usually takes four days to a workweek .
When they ’re an column inch or two marvelous , reduce the seedlings to stand three to five column inch apart , depending on the variety you are growing .
If you wish to start your seed indoors , sow them a quarter - inch deep and about an in apart in a flat or in case-by-case cells filled with about an column inch of pre - moistened potting mix or commercial cum starting medium .
Once the seeds sprout , move them to a sunny windowsill or somewhere else so they ’ll have about five hour of sun per day . Keep the stain moist and keep them out of verbatim light .
Once they ’re a couple of inches tall , you could transfer them into containers .
Plant them out of doors in jackpot in spring a week or two after the average last freeze appointment in your area . Only plant once the nighttime temperatures are reliably above 50 ° F .
practice a spoon or trowel to make a space for the root musket ball of each transplant .
Ease each start from its cell or tray and post it directly in the kettle of fish , making certain the top of the root ball aligns with the dirt surface and the origin are beneath the territory .
Backfill with soil , pack it down with the tips of your fingers and then water thoroughly , stopping only when you see the excess draining out of the hole at the bottom of the pot .
How to Grow
You ’ll need to water containers more often to give bok choy the moisture it requires , since its roots ca n’t escape the bay window to try more water on their own , as they would if they were farm in the ground .
Container - grown bok choy is thirsty whenever the top column inch or so of soil is dry to the hint . Just steep your pinkie finger in the sharpness of the container to find out if the plants need more water .
If the rain does n’t keep the grime moist , give the plant supplemental water , pouring it into the mountain at the soil descent until you see it draining out of the bottom .
The plant may also need a nutrient hike every couple of weeks , especially if you ’ve spotted yellowing leave or the development rate is n’t keeping tread with the cultivar ’s turn of years to maturity list on the seed packet .
In this face , run with half - strength limpid fertilizer that ’s high in nitrogen .
Fox Farm Liquid Fertilizer
Fox Farm 6 - 4 - 4 Grow magnanimous liquid fertilizer is a desirable choice , and it isavailable via Amazon .
A one- to two - in bed of mulch can also be beneficial for H2O holding and weed stifling . But it needs to be placed at least a couple of inches from the fundament of each plant .
If you ca n’t reach that spacing because you ’re spring up in a little pot , you ’ll postulate to forgo the mulch and be extra conscientious about lacrimation and checking the container for weeds before they gain a stronghold .
When you ’re grow in a colder climate , you could attempt to eke a few more Clarence Shepard Day Jr. from the develop time of year by bringing the pots into agreenhouseorcold frameahead of heavy icing .
Growing Tips
Cultivars to Select
Ahead of determine which cultivars to found , it ’s a good estimation to make yourself conversant with thedifference between bok choy and babe bok choy .
Any diversity can be grown to just baby leaf size , and harvested at about six to 10 column inch tall .
If you contrive to beak yours early , you’re able to opt for any type of pak choi you’re able to incur . You do n’t have to care that plants you reap while they ’re still immature and mostly leafy will propagate too much or eat up the dirt and water supply when they spring up too darn big because you ’ll pull them before there ’s any threat of that .
But you may want to prefer a echt gnome motley that transcend out at four to five inches . These cultivars have been spawn to mature speedily , usually hit full - size in 30 to 45 day .
They are also shorter and diffuse less than standard types , which can be idealistic for container growing .
Here are two type that do well in containers :
Baby Choi
This cultivar work rosette of crinkly , spoon - shaped green leaf on pale bow .
‘ Baby Choi ’
The plants can be harvested at six inches tall in 30 to 35 days , but they ’ll mature to a mature stature over 12 inches in 55 to 60 days .
Organic ‘ Baby Choi ’ isavailable in 200 - ejaculate packets from Burpee .
Toy Choy
to the full mature in just 30 to 35 Day , ‘ Toy Choy ’ tolerates heat , scatter just five inches , and grows five inches tall . Its stalks are white and duncical , while the foliage are a racy , mysterious , glum putting green .
‘ Toy Choy ’
‘ Toy Choy ’ isavailable in 60 - seed mail boat from Botanical Interests .
Managing Pests and Disease
Even when it ’s grow in a container , bok choy is susceptible to a number of insect cuss and disease .
Remember , bar is always better than discussion , and far less costly than destroying affected works and get all over again with uninfected container and fresh growing medium .
The bearing of pest can also contribute to the spreading of bacterial and fungal disease .
Pests
It is commodious to be able to move all the vegetables you ’re grow in container away from other affected plant , and to be able to cover them easily to stuff certain insects .
If certain type of bug are spectacular in your area , you may require to resort to grow your bok choy beneath arowcover , which can keep insects out while let water and light to reach the commons .
Once the plants are established , make it a point to analyze the leaves on a regular basis to make trusted there are no louse larvae getting quick to devour the harvest . Here are a few to watch for :
Brassicas include pak choi are a favorite snack of these icky slight sap - suckers that can also help spreadturnip mosaic virus .
If you search spanking and catch them before they ’ve open extensively , you may be able to get rid of them with a strong spray from thegarden hose .
When they ’re more widespread , treating with neem oil or insecticidal soap may be take to bring them back under control .
Our guide will tell you all you call for to acknowledge aboutdetecting , handle , and preventing aphids .

Disease
If you may minimize worm pests , that go bad a long way towards preventing multiple diseases , since bug can spread harmful bacteria and fungus kingdom .
You should also make an effort to water at the ground bloodline , not from overhead , since leaves that stay on wet overnight have substantially greater betting odds of developing bacterial and fungal disease . Splashing dirt onto the plant can also lead to disease matter .
copious airflow can facilitate to preclude various fungous conditions , include downy mildew .
This bacterial infection is caused byXanthomonas campestrispv.campestris . You ’ll be able-bodied to recognize it from the yellow splotches it create on leaf bound .
They ’ll keep get dark , finally turning calamitous and outright killing your pak choi .

Harvesting and Storage
Even when you ’ve just embed a modest amount , it ’s pleasing to beak the bok choy you ’ve arise yourself , whether that ’s a few babe leaves for the salad or entire full - sizing head of a nanus variety for braising or stir - frying .
The babe leaf of standard pak choi varieties are ready to blame when they reach six to 10 inch tall , typically 30 to 35 days after the seeds sprout .
Of naturally , some of the nanus varieties reach their full size in the same amount of time . you could pick them once they ’ve matured , which ordinarily takes about 30 to 40 day .
you could also glean the leaf from dwarf varieties when the plants are just a twosome of inches marvelous . I guess that would make them child - child farewell , heh …
Since you do n’t have to tramp out to a garden to do the picking , it ’s simple-minded to use the “ cut and come again ” method of harvest a few tabu leave first , leaving the sum of each plant to keep growing .
Use a sharp knife to cautiously skin away a few older leaves , pull in the cuts one inch above the territory line .
If you want the whole cluster to make or eat fresh right now , gently lift the bowl - shaped base of the bow with one hand . sheer the root stem that sits below the stand and ease the integral head of bok choy away from the pedestal of the plant .
you could also pry the entire plant out of the soil with a trowel , shake any grime promiscuous , and take care of lop the root from the core once it ’s out of the terra firma .
Of of course , an uprooted drumhead of bok choy wo n’t grow any more parting , while one that you sever at the base may send up some more shoots .
Keep in mind , you ca n’t keep doing the “ cut and come again ” routine endlessly . After a few big cuts , the leave of absence wo n’t be as tender or sapid when they grow back .
But that ’s cool , because you could always sow some more seed or grow some more transplants , either now if it ’s not too late in the time of year , or next surrender or spring .

Once you ’ve baffle the harvest in helping hand , it ’s best to use it immediately .
Like othercruciferous vegetable , bok choy tastes better when it ’s freshly clean . Wash it right on before you want to eat it or manipulate with it .
You may want to reduce the stems from the base at this point , so you could experiment withregrowing the scrapsfor a repeat bok choy harvesting .
If that does n’t invoke to you , leave the base entire and place the full head or separated leaves in the veggie crisper . Bok choy will remain refreshed for up to five Day in a zip - top bag in the electric refrigerator , but do n’t push that deadline unless you want to lose much of the taste and texture .
Recipes and Cooking Ideas
Unless you set loads of containers , I foretell you will run out of pak choi long before you black market out of way to enjoy the crop .
you’re able to bulge out by adding the wise baby leaves to a spring commixture salad or whir a fistful in a smoothy .
Our babe site , Foodal , boast a recipe for a Get Well Green smoothy , and it ’s simple to deputize child leave in stead of all or some of thekaleorspinachthat ’s called for .
you may shake - fry or braise full - size pak choi leave and stalks for a delectable Asiatic - style side dish , or stir them into soup or stew , too .
Just make certain to cut the stalks from the leaves for those hot , brothy dish , since the crisp livid centers need to cook for a few minutes to be flavourful but still crunchy .
The leafage taste best when they ’re only shortly wilted . Chop them into pieces or ribbons , and impart them in the last min of cooking , at the same time as other fine - flavored fresh ingredients likebasilor Spinacia oleracea .
Should you need further inspiration , go ahead and try this salad formulation I discover from a PTA mom when my youngster were high schoolers .
essentially , you slicefresh scallions , white-hot and green parts , and baby bok choy leaf , and dispose them together .
About six cup aggregate will feed four mass . align the onion - to - pak choi proportion to suit your family ’s tastes .
Next , create a crunchy , sweet topping . Melt together two tablespoons of butter and two tablespoons of granulated sugar in a nonstick cooking pan on medium estrus , stirring constantly . This will take about three minutes .
tote up a cupful of broken , uncooked ramen noodle pieces ( without the seasoning parcel ) and a half cup of shredded Prunus amygdalus . wangle until the noodles and almonds are just golden , for about five minutes , stirring all the while .
Remove the topping commixture from the heat energy and immediately convulse it with the invigorated veg , and store bought sesame dressing to taste .
you’re able to save any unused topping in an airtight container for up to a week , but I ’ll be good : I ’ve never had one excess particle left over .
The Joy of Container-Grown Bok Choy
Along with the outer space - saving benefits , I find that sowing a twosome of pots of bok choy is reassuring .
It would be daunting to protect a large planting from cold or heating plant , but I know I ’ll be able to toss a art object of row covert over the top of the inning of my one - gal container when cold-blooded weather bulk large , no problem .
And I can hands down tote the pots indoors for a few days if sear temperature are foreshadow .
Although the harvest is small - scale , I ’m well-chosen cognize I ’ll have a honest beginning of leafy greens in the weeks and sometimes month when other homegrown vegetables are only a fond memory .
I hope you already partake in my posture about container - grown bok choy , or that you will once you start your own seeds or produce transplants in the coming month .
Are you a veteran vegetable gardener who ’s already explored this option ? Or maybe a founding father who ’s giving it a go ?
