How to Sow
Sow appropriately for early, mid-season or late harvest.
Bunching onions grow anywhere but you will need to add some chalk to sandy soil. There are two ways of sowing:
- Sow directly into the garden, full sun, March or April as soon as weather conditions allow. Loosen the soil with a fork to at least 30 cm deep. Sowing can be done in two ways. 1. Draw a straight furrow, approx 1 cm deep. Label your row. Mix the seed with some sharp sand and sprinkle it along the row as thinly as possible between thumb and forefinger. A perfect seed distance is 5-7 cm. Cover the seeds with 2 cm of soil, press carefully down and sprinkle each furrow with water. Plant more rows at 25 cm apart. The seeds will germinate within 3-4 weeks and seedlings need no thinning out.
- Sow indoors in a tray from the end of February in about 5 cm of soil. Spread the seeds over the tray and scatter a layer of soil on top to about 1 cm. Sprinkle with water and stand somewhere at room temperature. When the plants are 10-12 cm, plant them out along a row; every 10 cm, one seedling. Allow the plant hole to stay open and water immediately (this is how to plant leek seedlings too). More rows can be planted out at 25 cm apart.
Water extra in dry periods and keep the bed free from weeds to encourage your bunching onion to grow well.
This crop is ready to harvest when the outer leaves turn yellow or already dried up, around September-October. Harvest them with a rake - run the rake along the row and flip your bunching onions up. Shake of any excess soil from the onion stems let them dry on top of the soil (as long as it is not wet). Otherwise stack them in trays in a shed so that they can dry.
The bunching onion is milder flavoured than the common onion - something between leek and onion actually. It is a member of the onion family (Alliaceae).
If you do not harvest your bunching onions, they will shoot up the following spring again. You can harvest them as long as new leaves are growing but if you wait too long it will flower with a rather lovely globe flowers in white.
Bunching onions are reasonably hardy and if you plant them from August through October you can harvest them in early spring. Do give them some protection from severe frost. A cold-frame is ideal.
