I Planted An Onion From My Refrigerator And It Bolted

Question

How does the onion reproduce and how can I get more onions from the one I planted that has now bolted? Thank you

Answer 1

Most onions reproduce by seed, or by pup. Most modern onions will not reproduce reliably by way of pups, so that flowering stalk will be your best way forward.

Once the seeds mature, and are completely black, they are ready for planting. This article will help:
