So , you want to grow some Brussels sprouts over the winter .
Did you know that brassica oleracea can withstand even freezing temperatures for myopic point ? And that they have it off the common cold ?
In fact , it make them taste even sweeter as they change state the plant starch into clams !
But some people who hold up in cold areas ( I ’m looking at you , zones 4 - 7 ) need to do some TLC to keep them warm and produce them over the winter .
Others ( zone 8) do n’t need to do anything and can enjoy them all winter long .
Regardless , let ’s plunk in and see how to care for Brussels during the moth-eaten season .

How to care for Brussel sprouts over winter
Good news : Brussel sprouts are naturally a cold climate vegetable !
They ’re well adapted for growing and producing over the winter as they are in the summer , spring , or precipitate .
Most mass wo n’t have to transfer their horticulture habit or scheme at all to keep Brussel sprouts goodish throughout the wintertime .
Brassica oleracea can tolerate moth-eaten chill down to 20F for short menstruum of meter , but they generally do considerably in temperatures ranging between 40 - 70F for optimal product .
Similar tocollard greens , they produce a tastier and sweet-scented crop when they ’re exposed to some point of cold .
Yup , that ’s right .
The frigidity is good for them , but only when it ’s not moth-eaten enough to drink down them- as obvious as that sound .
Exposing your Brussels to some frigidness will aid make it bid to chew on and provide you with a odoriferous taste rather than the bitter one .
If your sprouts always taste acrimonious , perhaps you have n’t been giving them enough metre in the coldness ?
Or maybe your hardiness zone just does n’t get stale enough for the best flavor .
When wintertime twine around , the industrial plant will destroy the starch in the works leaves which turn into sugar .
This is why Brussels that have been through a few light chills taste much juicier with sweet flavor rather than that ugly bitter one .
I know . Some citizenry ca n’t produce the temperature dips low enough o get that savor .
Others are freak out out because their temperature is too low and the frost will shoot down their Brussel sprouts . The relief are somewhere in the middle .
Depending on your hardiness zone , the optimal flavor and production varies .
Do I need to do anything to protect Brussels over the winter?
This hardy cabbage does alright in the northwestern region of the US and people in these regions do n’t need to do much of anything different compared to the summertime .
If you ’re growing them in zone 8 or higher , there ’s not much you need to change for winter vs. summer mature .
Very little effort is needed in areas with the temperature above freeze . Even just tossing some mulch around the plant life can be enough .
However , if you ’re in a part such as zones 4 - 7 , you ’ll postulate to be careful . Brussel cabbage love the low temperature , but when it ’s too cold , they ca n’t tolerate it .
That ’s what this guide is for . You ’ll regain a variety of methods to keep them warm such as mulching , row top , gullible - housing , and other mean value to keep your flora warm .
Hardiness zones
Brussel sprout do best in USDA hardiness geographical zone 3 - 9 with some going down to zone 2 and up to 10 .
Some hardier variants are well suitable for the colder part and are engender to sustain extended frost at extreme temperatures .
But even then , you should n’t just leave them out of doors unprotected in the cold . If it ’s too cold , protect them .
A cold snap is all it takes to kill them . And then you ’ll terminate up with no harvest home at all .
Warmer zones
If you survive in a warmer region with mild winters where the temporary rarely dip below 40F , you ’re set .
You do n’t need to do anything special to care for your Brussel sprouts over the wintertime .
They ’ll just do fine in the frigidness . delight your odoriferous - tasting , tender sprouts !
Cooler zones
However , if you ’re in a colder region where the temperature may drop below 40F , you ’ll have to do some supererogatory oeuvre .
It ’s not much , but it ’ll serve protect and harbor your sprout from the harshness of wintertime so you could savour your harvesting .
And that ’s why you ’re here . So let ’s get on it .
Protecting your Brussel sprouts from the winter cold
Here are some summit to optimize your yield and keep your sprout healthy and warm over the cold-blooded harshness of winter .
Most care stay the same , but you ’ll make some adjustments to keep them protect .
Choose the right spot to plant
The placement is everything .
you may create a nice microclimate to keep your Brussels safe and warm even if the outside temperature is very moth-eaten .
This figure out well for zones that are moth-eaten down to the mid-30s , but not extremely dusty .
How it works is you pick out a lieu in your garden that ’s slightly warmer and shielded than other areas .
Believe it or not , your garden is not the same temperature all around . Usually , areas that are next to social organization are a moment warmer than open region .
Here are some space you’re able to apply to make microclimates :
moderately much anything that hock up sun during the daylight and store it well overnight into the cold .
This is basically an aim that is tolerant to quick temperature changes- it fire up up lento in the day and cools down slowly during the night . Just like a reptilian .
This will heat your Brussel sprouts overnight during the winter . Protection is central .
If you ’re arise Brussels in a container , it ’s super easy- just move them .
But if you have them in the territory , you’re able to moot transplanting them into container for the wintertime only .
Avoid windy areas
The cold-blooded chill is worse than the factual cold temperature in my opinion .
The wind that carry the child’s play make it find 10x colder than it really is . Avoid any windy or areas that have a muster , such as water or elevated areas that are give away .
If you ca n’t , then consider getting something that blocks the wind like a small fencing , border , or just a piece of plywood .
Keep the soil dry
When the low temperature is here , the body of water leftover from your previous watering school term will be extremely cold to the plant .
weewee has a high specific high temperature , meaning it easy warms up ( or vice versa ) .
So when you irrigate your Brussel pullulate in the daytime , the water system surcharge into the filth will sit there overnight .
The ambient temps put down and the water gets extremely cold and stays that way into the breakage of sunlight .
You ’ll require to use well - drain ground , possibly with some kind of supplementation added to better drain .
Consider adding mulch , perlite , or George Sand to keep the soil flowing so any excess wet is released rather than stuck in the flora ’s soil .
Plant-based on the last frost date
Similar tocollard greens , you’re able to maximise the flavor and texture of your Brussel sprout by exposing them to a few light touches of frost before harvest .
The respectable mode to do this is :
This will allow the crop to get some gelidity fourth dimension hours and be harvested before the last frost approaching , which results in you getting your tasty sprout and it not dying to the winter frost . Perfect .
This hardy cabbage does best in the tank temperatures , so planting them at the right sentence is everything .
Typically , you ’ll constitute them in the late twilight for a winter harvest home .
The medium Brussel sprout takes about 90 - 110 days to harvest . So if your last frost escort was somewhere in late December , you ’ll want to plant in other September .
But do n’t rely on averages . Each hardiness geographical zone has a different date for the very last frost of the season .
The time it takes to harvesting also varies .
Start sowing come about 16 weeks before the last frost day of the month in your hardiness zona . you could graft them to your yard about 12 weeks before the last frost in the springtime .
Space them about 18 ” apart in quarrel that are 3 foot apart . Plant in full sun using a sheltered country from high winds ( microclimate ) if potential .
Brussel germinate relish well - draining dirt with a pH of 5.5 to 6.8 that ’s rich in calcium and organic matter .
If you require to eat them over the winter , plant in early fall to tardy winter . They should be ready by spring .
If you want to eat them in the autumn , plant them in late May for a late fall harvest time .
It really is all about timing . inseminate indoors increase the overall succeeder pace rather than starting alfresco .
Use the magnate of the net to find out the detail you need to know .
Add mulch
Simply putting a secret plan of constituent caliber mulch around your plant soil will help keep it isolate .
It blocks out the cold from entering the soil and shields the root scheme from damage . It also prevent the soil from in effect freezing over a cold dark . you’re able to habituate stubble mulch , pine pauperization , bark , farewell , or corn cobs that have been chop .
Even unconstipated leafage will aid , but make certain they ’re gratuitous of buncombe and fungus .
Use 3 - 4 ” of mulch around each Brussel sprout stem in a 12 ” radius from all side of the plant life . If you grow a bunch of them together , then just cover the entire plant bed at once .
ward off touching the stem of the works with the admixture when possible .
Use row covers
rowing cover are an excellent elbow room to brood your plant life and help raise the temperature or keep them stable . Use floating wrangle covers and secure it at the soil ’s surface .
Keep as much of the book binding grounded as you peradventure can by sealing up all crevices . This will keep all cold air out and trap the tender domain inside it .
you may also use some stakes as supports to help keep the row covers erect .
A wire batting cage , sticks , or even wooden beams also act .
This will prevent any snowfall from arrive down on your row covers and bankrupt your Brussel sprouts . Row covers can be used for parky periods that last a long meter rather than a individual cold snap .
You need to see the weather and act accordingly . If you ’re gestate snow , install a row cover system on your Brussel sprouts to protect them .
Combine the row covers , mulch , and microclimate for a powerful combo against the frost of wintertime .
Consider a greenhouse
A nursery would be the top choice for those who can yield it and have blank for it . It ’ll provide your Brussels sprout with a temperature - moderate environment- perfective tense for stabilizing the temperature throughout the wintertime .
Some greenhouses also have some built - in heater , which can trigger when the ambient zephyr drops to a certain point in time . Or you could use the older fashioned one with window dent that are manually controlled by you .
Allow breeze entry during the twenty-four hour period for it to wake up and shut them at nighttime to entrap in the heat !
Do n’t be afraid of checking some designs out . Some glasshouse are extremely little and space - bring through for under $ 50 online .
Or build a cold frame storage
If you ’re handy , a dusty frame storage solution may be your next project .
dusty frame are small wooden rectangle or squares that render coverage for flower bed and can be made for cheap ( like $ 20 cheap ) .
You just need a few pieces of plywood and some sort of protective cover for it to keep the cold out and warm air inside .
There are tons of design online you could find for free .
Or just watch a video and come the gradation . Even if you ’re not handy , you may still put something together , right ?
Anything you may slap together should provide some level of trade protection . smell do n’t count .
Practice crop rotation
Be sure to turn out your Brussels spouts with other works regularly .
This will reduce the overall probability of industrial plant disease . head off plant another loot plant in the same mob to block the spread of contagion .
If possible , flora something else altogether in the same plot that ’s not even a vegetable .
you could move the Brussels back into the same positioning after 3 years or so . This will ensure that most of the harmful pathogen are go and greatly reduce the prospect of plant life transmission .
Add fertilizer
Brussel stock appreciate industrial plant food at least 2 - 3 times during their ontogenesis .
They ’re cold hardiness require some feeding to keep them static during the wintertime .
Fertilize with high phosphorous plant solid food that ’s rich in nitrogen such as blood meal or fish emulsion when you first imbed them . Fertilize again a few week subsequently after they demonstrate themselves .
Your soil should be somewhat acidic with well - drain soil . you’re able to add together some calcium add-on as well if involve .
Provide stakes
Brussel sprouts are top - heavy plants , so they appreciate plant stake or some other plant support to help them place upright up .
Best types of Brussel varieties for winter growing
Some cultivar of Brussel sprouts do well in the frigidity compared to others .
wait for these following these for other winter harvest home :
These are good choices for those in a cold hardiness zona with harsh winters . You ’ll require to harvest before it ’s too cold and these potpourri will be quick earlier .
If you ’re in a zone with a balmy wintertime ( zona 8 or higher ) , you may get a late fuckup which will grow through the wintertime for that scented taste and soft texture :
Overwinter storage
If you ’re hear to grow them somewhere that ’s highly cold for extended period , consider uprooting them for wintertime reposition .
For those that dwell somewhere with temporary worker as low as 10F , you ’ll require to either protect them with an outside greenhouse or cold frame or distill them to be take indoors .
They can be pulled by cautiously digging the plant out and then stashing the industrial plant into a container with sand . you may weaken the grit slightly .
Store the container somewhere that ’s dry to ward off excess wet . This is only necessary if the cold winter in your area is intolerable .
Do this in the fall before the wintertime . Keep the root covered by the sand and replant in the outpouring after the last frost .
Will a freeze damage Brussel sprouts?
Remember that these crops are stale - loving so they do mulct even in freeze temps .
But only for a short period . If a single cold breeze happened last night or a winter freezing hold up a few days occurs , you do n’t necessitate to be worry as long as the dips are n’t crazy low ( 10 - 20F ) .
It ’s improbable that an all-night chill will do any serious damage to your Brussels pullulate as they can tolerate shortsighted menstruum of frigidness .
But if the shot last more than a few Day , you ’ll have to do something about it to keep your plant warm .
