ANSWER : By hack the bottom of an onion light bulb off and engraft it into grunge , you could farm your own onions from cuttings . With a bit of knowledge , as well as prison term , patience , and rafts of water , you’re able to grow an onion plant from an onion plant bottom in just 90 to 120 days . you could utilise most any diversity of onion for this technique , even onions purchased from the grocery store . ensure that the Allium cepa that you are using is still hefty and fresh .
First , chop the bottom of the parent Allium cepa about one in from the bottom using a needlelike tongue and remove the outer skin . If you are growing your onion plant indoors , you could plant it at any meter of year , but if you are growing it out of doors , you should bulge your cuttings in former spring .
Next , leave the cut onion bottom out to dry out for 12 to 24 hours on a dry surface with the cut side facing up . Let the onion bottom dry out until it is juiceless to the touch and cauterise . Make an X by jab four toothpick into the side of the onion plant bottom , pushing the toothpick halfway in on each side . The toothpicks should be equally space apart , allowing you to set aside your onion plant bottom over water while it develops roots .
Then , fill a small trough to the brim with urine and come out it on a savorless surface , preferably a sunny windowsill , hanging your onion bottom on top so that the bottom touches the open of the water and forget it in station for three to four day . The roll ’s diameter should be less across-the-board than the length of the toothpicks . Once the cutting has developed white-hot root from the bottom side , it is ready to plant .
Next , fill a orotund pot with drainage holes in the bottom about halfway full with a well - drain potting mix . Place the onion cut in the pot , positioning it in the center , root - side down and fill the rest of the pot with dirt , leaving one to two inches of way at the top of the hatful . you could keep the pot indoors or alfresco in sunny weather , just ensure it get as much sunlight as potential . you’re able to also select to originate your thinning out of doors in a garden bed , as long as your garden soil is well - draining and you select a sunny position . irrigate the onion plant cutting immediately after engraft it , giving the thinning enough water so that the soil is damp but not soak wet .
After watering , spray a N fertilizer into the filth , following the direction on the label for how much spray to use . Give your onion plant about one inch of water per hebdomad , watering when the soil is dry to the touch on the top layer . Pull up any Mary Jane on a regular basis if you choose to plant your onion outside . Fertilize your onion every two weeks with a nitrogen - rich fertilizer until the bulb begin to poke from the dirt . In approximately 90 to 120 days , the Allium cepa will begin to shape flowers . This means that your onion is ready to harvest . Pull the onion out of the land by pulling on the base of its green foliage to dislodge it from the soil .
