So, you have an onion or two that you bought from the grocery store, that have now sprouted in the pantry. And you’re wondering, “Can I plant these sprouted onions and grow a new, fresh onion?” In short the answer is, YES!
First, you need to peel the onion, layer by layer, down to the center.
Once you get to the center, carefully peel away the additional layers until you start to reveal separate plants!
Separate each onion plant by carefully cutting apart at the root with a serrated kitchen knife.
Now it’s time to plant your onion sprouts. Your onion sprouts will hang around for up to 3 weeks before you need to plant them.
Continue to water and weed around your onion plants. Fertilize if your soil is not very rich.
Your onions should grow for about 3 months to reach the optimum size which is when the bulb is the size of a baseball.
