When to Harvest Spring Onions

Spring onions are ready to harvest once stems reach a usable size. Because they grow quickly, they can often be harvested only a few weeks after planting.

In the UK, spring onions can be harvested throughout the growing season depending on planting time.

Harvesting regularly helps maintain tender stems.

Harvesting spring onions carefully
