Walking onion: Sowing, planting and harvest calendar
How do you propagate walking onions from bulbils?
To propagate your walking onion outdoors, plant the aerial bulbils produced at the tops of the stalks. These are small bulbs, not seeds. Harvest them once developed and their outer skins are drying. You can plant them in late summer or autumn, or keep them dry and airy for spring planting, depending on climate.
Separate the bulbils when planting. Choose a sunny position with weed-free, loose, well-drained soil. Place them base down and pointed end up, shallowly, around 2–3 cm deep for small bulbils, following the grower’s guidance. Leave about 20–30 cm between future plants. Water gently to help rooting, without soaking the soil.
Weed by hand near young shoots and watch for slug damage or bulbils pulled out by birds. Direct planting does not require routine transplanting. If you let the stalks bend to the ground, bulbils may root by themselves; harvest them beforehand if you want to limit the clump’s spread.

Remove weeds around young bulbs, especially if they shade them. Close to the plants, weed by hand to protect the roots and avoid damaging the bulbs.
