Because onion have a long season , they must be planted among the first of your cum – about 8 - 10 weeks before your average date of last frost . found them in a good seed starting mix with a direct light source and a heat mat under the dope .
As your onion grow taller , move the light source further to advance emergence . You should not need to separate them until they go into the ground , but if they start to overcrowd their jackpot they can be spread out out to allow more space .
We have had decent luck develop onion from seed , but the rate of achiever from sprouting to transplanting is low than that of some of our other vegetables . I believe this is because Allium cepa spend so long indoors ; we just ca n’t always keep them healthy . This has run us to search other option , such as the transplanting and “ set ” options below .
If you live in a climate where your winter are not as rough , you may really plant onion plant seed in the declension . They will overwinter in the soil and get an early start the next spring .
How to Grow Onions from Transplants (or Seedlings)
grow onions from transplants simply intend letting someone else get the seeds for you . onion plant seedling can be buy from many gardening centers as well as online .
They ’re typically about 6 - 8″ tall and look like large circular blade of supergrass . When you order transplantation shipped by ring mail , they will come in a bunch that seems dried out .

Onion Set are onions that have already had one time of year of growth . When planted , they will enter their second season and come to full size in your garden . They basically look like modest onion plant bulb that are dried out and somewhat bizarre .
The best exercise set should be about the size of a marble ; if they are larger than that , they run to bolt early ( set prime above ground ) , and the bulb beneath the ground will not get as turgid .
Onion set are planted much like graft but wo n’t show the green part above earth until they rise . embed them about 4″ asunder , about 1 - 2″ deep , in 12 - 18″ between rows .
onion plant sets help to guarantee an onion plant harvest because you are convey a head start on the size and graduated table of your industrial plant .
However , the downside is that your choices will be limit . There will not be as many onion plant varieties usable to you as sets and you may have to simply choose between “ yellow , white , or red ” varieties .

Planting and Caring for Onions
When planting your onions , be certain that you are starting with high - quality grease . improve your soil withcompostand a high - caliber constituent fertilizer at planting metre to give your onions the best scene at growth . onion love highnitrogen fertilizerslike blood meal , bat guano , composted chicken manure , or cottonseed repast .

Harvesting and Storing Onions
Onions are ready to glean when the top of the plant life twist yellow or dark-brown and starts to fall over . This mean that they have reached their full potential for long - endure storage . That said , you’re able to harvest an Allium cepa as soon as you see the bulb if you plan to use it right by , but do this sparingly , as those bulbs will be low and wo n’t last as long .
The respectable time to harvest home onions is in the morning on a gay Clarence Shepard Day Jr. when the grease is still slightly dampish and will release them pronto . Then , lay your onion in the Sunday to dry out for about two sidereal day .
Once the onions are thoroughly dry , you may cut off the tops and store them in a cool , dark station for up to a few calendar month .
The process of harvest home and curing onions is similar to that ofdrying and cure ail , and concern must be taken to ensure that onions are exhaustively wry before storing . The entire neck should be wry down to where it meets the bulb before cutting and storing .
