Signs Of Flower Development
Onion bulbs first show small green shoots. These shoots grow taller each day. Soon, you see tiny buds at the top. These buds are important. They will turn into flowers. Buds begin to swell and change color. This is a good sign. It means flowers are coming.
Promoting Flower Growth

Onions produce seeds in their second year. The best time to harvest is when the flower heads dry. The seeds should turn black. You need to wait for this stage. If you harvest too early, the seeds might not be ready. Late harvest can cause seed loss. Timing is very important.
First, cut the flower heads with scissors. Place them in a paper bag. Shake the bag to release the seeds. Separate the seeds from the chaff. Store the seeds in a cool, dry place. Use envelopes or small jars. Label the containers with the date. This helps you remember when you collected them.
