What You’ll Learn

Pull out those tissue and a knife . We ’re uncase back all the layer of these veggie staples up ahead .

Cultivation and History

onion plant have been a part of human culture for so long that we are n’t indisputable where they originated , but it was in all probability in Central Asia , where so many fantastic intellectual nourishment have come from .

We know that they ’ve been cultivated since the Bronze Age . Ancient Egyptians worshiped them , jock in Ancient Greece ate them to improve their operation , and Europeans and later American settlers used them to care for all kind of ailments .

The full term “ onion plant ” is a broad signifier of several different type of plants .

A close up vertical image of onions growing in the garden. To the top and bottom of the frame is green and white printed text.

These plant life are grouped as either biennial or perennials . Shallotsand multiplier onion plant ( genus Allium cepavar.aggregatum ) are perennial and will number back year after yr on their own in warmer region .

Egyptian walk onions(Allium cepavar.proliferum ) spread themselves around , effectively acting as perennials .

two-year type are usually grown as annuals and are harvested in one time of year .

you could also aggroup them as fresh , unwashed , or memory board ; bunching ( the mass radical ) ; or walking ( the proliferous group ) .

Bunching case includescallionsand spring onions , and they ’re ordinarily quick in just two month , or sometimes less .

Fresh onions take a farsighted growing time of year and they typically have a more high spirit , with less of a stifling punch . Storage types hold less wet and have a more sulphuric , substantial flavour . They can be put in for months in a coolheaded , dry locating .

Each onion is made up of a fraud - straw compose of overlapping leaves . Underground , the bulb has multiple level , and each one is linked to a foliage .

On the outside of the bulb is a tissue layer that dry out out to form the papery coating that you peel off before you commence chopping .

The barbed flavor is thanks to the sulfur ( thiosulfate ) in the plant . It ’s present throughout but digest in the bulb . The sulphur is also responsible for for those tears you might shed when hack your onions .

In lawsuit you ’re curious why an onion sense oniony when you break up it up , but it ’s not until you slice into it that all the scent is released , that ’s because amino acids and a defensive enzyme call alliinase are stack away in disjoined parts of the plant .

When they immix as you open them up by chopping or crushing the membrane , the scent and nip is released .

This is the plant ’s last - ditch attempt at assign off predators , but fortunately or alas , depending on how you look at it , it ’s what draws human race to them .

Onion Propagation

Before set , it ’s wise todo a soil test . That way , you know if you should add plant food or falsify the pH before planting . It ’s always easier to do this before your plant are in the ground .

The plants need a pH between 6.0 and 7.0 with well - run out sandy to loamy ground .

permit ’s take a look at a few options for pass around plants .

From Seed

gardener in some parts of the country have a straight develop season , without the threat of prolonged freezing temperature . In those spot , there is no need to seed indoors to escape the biting winter cold .

If you happen to subsist in a region where your wintertime are mild enough that you do n’t ever get hoar or freeze temperature , you ’re favorable !

you could sow directly into the ground with confidence that the semen will be warm enough to germinate and grow . Sow your germ in mid - free fall or other spring .

For those in regions with colder winters , develop onions can finger like a airstream against the clock to see who will win .

If the ground freezes in wintertime and you experience frigid temperature below 32 ° atomic number 9 , bulge your seed inside about eight to 10 weeks before your last predicted icing date .

If you choose this method , there are a few additional steps you must take to control a hefty , luxuriously - give crop . You will need a few thing , admit seed - take up traysand agood seed - start medium .

you could also employ recycled container from salad mixes or charge plate take - home container from your local delicatessen , planting in rows of seven to 10 seeds each . The choice is yours .

Fill your chosen tray with moistened dirt , pack down the land just a bit .

Sow two to four seeds in each cell a quarter - in deep , or sow seeds about two inches asunder , depending on what type you ’re growing .

Water and set away in a affectionate , well - ventilated locating with several time of day of direct sunlight .

If your growing environment is n’t on a regular basis above 60 ° F , use a seedling warming Master of Arts in Teaching to help oneself with multiplication . A soil temperature of 75 ° F is optimum .

Place dome or charge plate over the trays to help hold moisture . Water whenever you comment that the dirt reckon and feel dry on the surface .

When you notice sprouting , which typically go on within a workweek , you need to be sure that your onion get enough illumination from that breaker point on .

Ideally , the flora would like to have 12 hours of light and 12 hr of duskiness per solar day , depending on the eccentric . We ’ll talk about foresighted solar day , poor day , and medium onions in a bit if you are n’t already familiar with these terms .

During the wintertime when the sun is n’t particularly strong , usesupplemental grow lightsto keep your seedlings happy and healthy .

wakeful hood are easy to bump in any ironware memory board , as are the accompanying grow bulb . Look for LED design for starting seedlings , as these typically have a low heat output with suitable coverage .

Once germinated , onion seedlings tend to rise rapidly beneath light . They will emerge from the dirt and grow grandiloquent very fast , so it is authoritative to monitor them .

Be sure to remove the humidity dome and the warming lustrelessness once you have an inch of growing , since your plants are now ready to grow on their own .

When you acknowledge that the seedling are about five inches magniloquent , take a sharp , fresh pair of scissors and geld the tops off , leaving about two column inch of the plant   intact .

Cutting the tops will make your seedling stronger and thicker , which will be good when you are transplanting them into your garden .

Also note that you may apply these trimmings in salads , soups , or other dishes . They are delicious !

Between propagation and transplanting Trygve Lie hardening off . It is imperative to verify that your seedlings will be firm enough to withstand lower temperatures , wind , and less frequent watering .

Now is the time to move your tray alfresco for gradually increase periods of meter , exposing them to the elements .

A close up horizontal image of caterpillars munching away at foliage.

Put your plant alfresco in a protect spot during periods of more pleasant weather condition if potential , begin with a few time of day on a sunny day and extending incrementally to an entire day of exposure .

Do this for about a hebdomad , just before you are ready to transplant .

If you live in a mild clime that provide for unmediated seeding without the threat of frozen ground or torrential rains and cold temperatures , then you do n’t have to worry about starting onions indoors .

A skilful option may be to skip the ejaculate and consider planting onion readiness or else .

From Transplants or Sets

Sets are inactive bulbs grow from ejaculate in the previous time of year .

They are smaller than full - sized incandescent lamp and were intentionally sewn by growers close together , not thinned out as they grow .

This further a robust lightbulb apotheosis for establish the following year . Transplants are actively growing plants .

Both of these can be planted the same agency . The advantage of these over semen is your harvesting will be ready up to two months rather , but they cost more .

Harvested at the end of the summertime and dry for approximately four week or more , these light bulb are stored until they ’re needed for the next growing time of year , ready for you to imbed in your garden .

Transplant alfresco around your last presage hoar particular date . They can tolerate a light hoarfrost , but brood arise industrial plant if there ’s a surprise freeze .

You will postulate a few tools , such as :

Though it ’s not involve , I prefer planting in row . Decide how many row you need to accommodate the number of onions you desire to plant .

You ’ll want to provide for about six column inch between seedlings , and 12 to 18 inches between rows .

A close up horizontal image of foliage exhibiting signs of rust.

Put a stake in the footing at either end of where you plan to set each row . Attach a piece of music of twine to a stick on one end , stretch it to the spliff at the other goal of the row , and drop anchor it .

The bowed stringed instrument and the post make it well-situated to toil a prissy straight run-in , just by using the string as a road map .

Using a shovel or any other tool that will dig into the dirt , make your rows about two inch abstruse .

A close up vertical image of green onions freshly harvested with tiny bulbs.

Sometimes I just bend down and hale my bridge player along the crap just below each demarcation of twine , using my fingers to make a run-in . Sometimes I use the tip of a long - handled shovel or a spade . See what works well for you .

Sow like a shot into the soil , plant each set about one inch bass and six column inch away from the next Allium cepa in the row .

Transplants should be planted with an inch of growth below the grime and the top of the incandescent lamp . Be sure to lead 12 to 18 inches of space between each row to ensure a proper grow surround .

If you are transplant seedlings , you could found three seedling in a ball together , or you could choose to separate them and imbed each one individually .

Some gardener like to keep a few together , as they feel that it helps to increase take . Others prefer to keep each one on its own . That ’s your alternative .

Do what sense right , and keep distinction on your successes and failure from year to yr in yourgardening diary . I group my seedlings together in groups and have cracking results .

A close up horizontal image of freshly harvested onions set on a wooden table.

Once you ’ve establish all of the onions , cover up the rows with soil and tamp it down light . Do n’t crusade too hard . Everything that you plant in the garden needs some respiration room .

Label your rows with garden stake tags , so you ’ll have it away what ’s there . I love these wooden field stakesfrom High Mowing Seeds .

Wooden Field Stakes

They survive in in high spirits temperature without flex and melting like plastic tag can and you may reuse them for years .

It ’s a good estimation to put the planting date on your tags as well , so you have an idea of how long maturation in reality takes .

I also spell down all of my planting dates in my gardening journal . This is a great resource to have and to refer back to at the starting time of each growing time of year .

How to Grow Onions

As we said , onions postulate well - run out soil with a pH between 6.0 and 7.0 . Loamy , rich grime is best .

If you do n’t by nature have perfect land , and few of us do , crop in luck of constituent issue like well - rot compost . This increases drainage , ameliorate water retention , and adds nutrients to the grunge .

Manure work too , but make certain it ’s aged and not impudent . Fresh manure can stop bacteria and sess seeds , and it might burn plants .

A close up horizontal image of freshly homemade frittatas with scallions scattered around.

Clay grease is too compacted and clayey for the bulbs to grow , so you must improve the land orplant in a raised bedinstead .

Once planted , make certain your onions receive enough water . You do n’t need to rob them , you just want to ensure that the stain is sorry and moist . The plants have shallow roots , and they wo n’t spring up large bulbs if it ’s too ironic .

These plant need aboutan in of water per workweek . Whenever the top inch of filth dries out , it ’s time to add more water .

A close up horizontal image of bulb onions whole and sliced on a wooden chopping board.

Each time you tote up piddle , you need it to dowse about six inch bass . Sandy soil will postulate to be watered more often , and denser dirt less often .

A moisture metercan aid take the guesswork out of the watering equation or you may use a trowel to dig down next to the bulb and monitor the water deepness with your finger’s breadth .

Some people might need to water once a calendar week and others nearly daily , depending on their territory , the temperature , and recent rain .

Once they ’ve reached nigh to their matured height , you’re able to localize a thick layer of mulch around the plants to help oneself retain moisture , and also to reduce the amount of weed you will need to do .

I expend straw mulchbecause it locks moisture in and is season enough so that I do n’t have to worry about any insects that might be living in the medium , as you might find in hay . The last thing you require at this stage is to have to deal with undesirable insect visitor !

Keep in mind that onion need much more time to raise than some other crops , so you will be irrigate and weeding them quite a flake . Anything you may do to save metre and be more effective in your garden is a safe thing .

Allium cepa need regular eating to be healthy and grow big . If you did n’t do a soil test when you planted to determine what your stain is lacking , feed them 30 day after planting , once at the eye of the growing period , and lastly , 30 days before harvest home .

If you did a soil test , provender accordingly based on your solution .

Onions ask lots of nitrogen to develop , but too much will delay bulb shaping and make large neck opening . We do n’t need big necks in storage types because they make the curing outgrowth more difficult and lengthy .

Growing Tips

Maintenance

If you are grow cluster Allium cepa , gradually mound up territory around the root word of each plant to increase increase of the white part .

Otherwise , maintenance consist of snipping off any diseased , discredited , or pesterer - infested farewell .

veer off the scapes when they form , or they will take up some of the nutrients that we want going into the light bulb . Scapes are the flower stalks that take form as the industrial plant ages .

Weeding is central to a proficient harvest time because onion ca n’t compete with weeds at all . Just use uttermost caution as you weed so as not to touch the bulb .

That ’s why I normally hand - pull weeds rather than using any sort of pecker .

Onion Cultivars to Select

take the respectable onion cultivar depends in part on where you live . There are three different type : long day , short day , and intermediate or day - impersonal .

Long - day type will set up bulbs when there are around 16 hour of daylight . light - Clarence Shepard Day Jr. type place bulbs when there is about 10 to 12 hours of daylight . Intermediates sit down somewhere in between .

northerly gardeners should opt long types , southern gardeners need forgetful types , and those in the midsection can use either , but intermediates will grow well . Most growers in the US will require day - inert types unless you ’re in the uttermost north or south .

For a summing up of all of our dearie , visit our templet to the good onion for the home garden .

Managing Pests and Disease

Herbivores are n’t really interested in alliums , in general . If only dirt ball and pathogens feel the same way !

There are a few pesterer that can totally destroy your crops , and we ’ll talk about them first .

Insects

Insects are n’t bothered by that acid scent . While cuss might be nothing more than a nuisance in some crops , in onions , they can be a giving deal . Let ’s set out with one of the worst :

Allium foliage miner ( Phytomyza gymnostoma ) can absolutely wreck your total harvest time .

Right now , this pest is most usual in the Atlantic states , but it ’s making its path across the US .

The adult are small black or gray-haired flies , but it ’s not those that we ’re interested with since they do n’t harm the plants all that much . It ’s the larva that do the wrong .

The grownup females make several puncture along a folio and then lay eggs in those punctures . The larvae hachure and get eat on their path through the leafage toward the stem .

Not only do the little trails that they leave behind start the industrial plant up to all kinds of pathogens , but they yield the foliage and this can lead to decompose .

The second you see the telltale trails , chat our template to learn how to deal with genus Allium leaf minersbefore they destroy your craw .

Delia antiqua , or onion maggots in their larval leg , are frustrating blighter . The grownup calculate like little houseflies , so most of us overlook them when they ’re bring down our garden .

But they lie ballock on the soil , and the larvae crosshatch about a week later to course on the roots of the plant .

The most annoying part is that by the fourth dimension you see symptom on the above - ground parts , it ’s too late to take action to down the maggots .

When the maggots eat , they cause the bulb to rot and create an opening move for pathogen to record through . As the light bulb rots and disease potentially take up delay , the plant starts to droop and generally reckon sad .

The salutary way of life to head off this problem is to place yellow embarrassing traps near your onions . If you see adults , which are hump - back , brownish - gray flies , it ’s time to take action .

Control involvesfloating row covers , invitingbeneficial predatory insectsto the garden , and using the entomopathogenic nematodeSteinernema feltiae .

To memorize all aboutonion maggots and how to manage with them , visit our guide .

Along with maggots , Thrips tabaciis the other one that onion agriculturist dread as it has the potential to completely ruin your crop .

These slender , yellow - brown insect are n’t easy to see with the naked eye , but the price they cause is .

thripid are opportunists and they can eat a salmagundi of crops . They ’ll often start out on legumes or metric grain before moving onto onion . For that reason , it ’s best to avoid imbed these craw near each other .

They use their rasping - sucking mouthparts to describe out the blackjack from the leave of the works . As they make their way through your garden , your onions will start to develop silvery streak . The leafage might break and fold as well .

These pest also spread onion chickenhearted gnome virus .

If they come call up to your veg patch , run , do n’t walk , to ourguide on controlling thripid . Once symptom look , this suggest an ongoing infestation , so quick action is needed .

Row cover , reflective mulch , enticement , predatory insects like lacewings , and insecticides like grievous bodily harm and neem oil are all viable treatment options .

Disease

There is a prospicient listing of diseases that can spell disaster for your onion , like pink root , purplish blotch , damping off , downlike mould , viruses , and smut .

With good crop gyration and appropriate garden hygiene , you probably wo n’t run into these .

But the follow diseases are more common , and chances are high that you ’ll run into one at some peak :

due to the bacteriaPseudomonas viridiflava , bacterial rot causes the leave-taking to develop ellipse - forge , piddle - hook lesions that expand and spread . The bulb will also develop a band - like pattern and the scales will rot .

As the disease go on , the leave will break , with a corrugate appearing triggered by the protruding vein .

These bacteria have legion hosts , including brassicas , stone fruits , nightshades , and legumes like bean .

It also assail risky radish , dandelion , vetch , and thistle , which is another reason you need to keep weeds out of the garden . In fact , see to it weeds is a immense part of prevent this disease .

It can be seed - borne , or carried on the flatus or through water . Watering at the land grade to avoid splash is another important preventive .

If you see symptoms , dissemble rapidly . Once the bulb starts to moulder , there is n’t much you could do .

Treat the leaves with a copper fungicide and use a copper drench on the soil . replicate after two week have passed if unexampled symptom develop .

Fusarium oxysporumf . sp.cepaeis a fungus that causes necrotic , yellow leaves , beginning at the tips and locomote down to the foundation .

At the same time , the leaves might wilt . Underground , the bulb turns soggy and brownish .

Sometimes the symptom do n’t come out until you glean the electric light and they bulge out decompose away .

Sounds sorry , veracious ? It is .

The fungus thrive when temperature are between 59 and 80 ° F and it survives in the soil for ten , just waiting for an onion that has a trivial bit of damage caused during planting or by pests where it can get in .

It can also regain a host in oats , beans , corn , tomatoes , and sunflowers .

Rotate these , along with other alliums , out of your garden so that you only plant them once every four years in the same sphere . Take aid not to spite transplants and prevent pests like maggot from infesting your crops .

you’re able to also plant tolerant cultivars , like ‘ Dulce Reina , ’ ‘ Frontier , ’ ‘ Genesis , ’ ‘ Great westerly , ’ ‘ Green Banner , ’ ‘ Montclair , ’ ‘ Outlander , ’ ‘ Parade , ’ ‘ Pirate , ’ ‘ Red Devil , ’ ‘ Scorpio the Scorpion , ’ ‘ Sweet Jasper , ’ and ‘ White Castle . ’

You ’ve credibly do across an onion rotting away in a dish that you purchased at the memory .

grim stamp , caused byAspergillus niger , stimulate grim streaks to form under the paper and at the neck of the bulb . Advanced cases cause the integral bulbs to turn black and shrivel up .

While you could wash the black mold off and use the onion if it is n’t too far go , it ’s better to stave off this disease wholly in your homegrown craw .

Harvest your bulbs the moment they ’re ready and dry out them right away . There must be moisture present for at least six hour for the fungus to acquire , so keep on your harvest ironical is key .

Once the onions are cured if you ’re growing a store eccentric , they ’re less susceptible to black mold maturation .

But you’re able to also refrigerate your bulbs to further prevent the fungus from spread , since it need temperatures above 59 ° F to reproduce .

Botrytis squamosais a fungal pathogen that causes ellipse - shape , snowy lesions to recrudesce on the leaves . These may or may not have a silver halo . As the disease advances , it stunts medulla growth , and leaf tips will die out . In fact , whole foliage might die off altogether .

Because the pathogen can lie down dormant in plant dust or soil , it ’s unwashed and tends to return year after yr , especially in areas with high-pitched humidness or low air circulation .

As with many other disease , steady crop rotary motion will help forestall infection . Only plant alliums in the same sphere once every three years to avoid it . You should also space plant life fitly for airflow and remove all debris at the end of the growing season . Avoid overhead lacrimation .

Copper fungicide can arrest development , but there are some great merchandise out there develop specifically for deal fungal pathogen like botrytis .

CEASE , for representative , contains thebeneficial bacteriaBacillus subtilis , which outcompetes botrytis pathogens and disrupts their germination .

CEASE Biofungicide

you’re able to bring home a congius or 2.5 gallon jugfrom Arbico Organics .

I ’ve also had peck of succeeder with Mycostop , which uses a bacteria regain in peat moss calledStreptomycesstrain K61 to destroy pathogen .

Mycostop

It ’s alsoavailable at Arbico Organicsin five- or 25 - gram packet .

Onion rusting have stretch or round pustules to form on the undersurface of the leave and on the stems .

Caused byPuccinia porri , a type of fungus , it wo n’t usually kill your plant , but it can result in foreshorten vigor and smaller bulb .

The aforementioned cop fungicide and CEASE are both effective in treating this unwashed disease .

Harvesting

onion plant take up to four months to cultivate from plant to glean . If you want fountain onions , otherwise known as green onion plant , harvest them about 21 to 28 days after you ’ve planted your sets or a act longer for come planting .

These spring onion have a lighter and sweet-flavored flavor than matured onions that ’s wonderful in many recipes .

Fresh eating onions can be harvested fundamentally any sentence the bulb or greens have reached a size that you prefer , but before the top set out to turn icteric .

Otherwise , be patient , water , fertilize , and weed . Before you know it , gracious and plump onions will peek the diadem of their heads out of the grease to show you their advancement , though this wo n’t always happen .

If you feel muckle of overcast sidereal day and cool temperatures , the bulbs will take longer than usual to form .

For depot case , monitor them cautiously , detect when the long green tops begin to flop over and lie down down , changing colour from green to brown , indicating that it is harvesting time .

You want about one-half of the parting to be return over and turning yellow or chocolate-brown before you glean computer memory onions that will be cured .

expect for a cool , dry sidereal day to reap . This helps trammel the post - harvest rots that can impact onion .

Remove bulbs from the land by turn over down underneath them with a shovel or trowel and gently rear . At the same time , grip the tops at the base and mildly pull .

Preserving and Storing

When the weather condition is dry and cheery , many Fannie Farmer and backyard gardeners will pull up their onions and leave them on top of the territory in row for up to a week , allowing the Dominicus and melodic line to dry out them course .

If you do not have such fantastic conditions , harvest your storage onions and bring them into a well - ventilated arena like a barn or some kind of clear room .

unfold the onions out on a savourless Earth’s surface , like the floor or mesh drying rack , so that they can dry .

This process is call “ curing , ” and it is a critical step in the reposition operation . If they are not properly cure , Allium cepa will not have a long entrepot lifeat all , because the stay wet will cause them to waste .

You ’ll cognise they ’re ready when you cut off a top and point out that there is n’t anything oozing from the cut of meat . If they are n’t dry enough , a milky white substance will seep out , telling you that the onions involve more curing time .

Hang or lay the onions out in an area with good air circulation and out of direct Sunday to stay bring around .

Once properly cure , you’re able to begin the process of cutting off the teetotum , trim the roots , and bagging your onions for computer memory . When cured and stored by rights , some storage onions – such as ‘ Patterson ’ or ‘ Red Wing ’ – have a storage living of six calendar month or more !

springiness or brisk onions can be stored in the crisper drawer of your icebox . greenish onion wo n’t last as long as clean onion , but wait to get at least a calendar week of cold storage for greens .

Recipes and Cooking Ideas

Oh boy , where to get down ?

First things first , learn how to prep onionson our sister site , Foodal . Once you ’re such a master at slice and dice that you could acquire a Top Chef Quickfire challenge , you’re able to start cooking .

One of my favorite ways to use onion is to caramelize them . There is no elbow room to hurry this process , so ensure you have about an hour to do it .

slit the onion to a consistent width . That ’s fundamental , because uneven slice will lead in some bits being burn and others being raw .

Now , put a glug of olive vegetable oil in a goat god . I favour to use a heavy glazed hurtle iron goat god because it has enough stick to really get the caramelization going , but it is n’t so sticky that the pieces will stick to the pan .

It also go around the high temperature evenly , even when you ’re make on a very unevenly warming stove .

Turn the heat to medium - low-down and add the onions . You only need to caramelise one or two onion plant at a time , look on the size of your container . Too many slices packed into a pan will have a hard time cooking in good order .
