Potato onion: Sowing, planting and harvest calendar
How do you plant potato onions?
To propagate your potato onions, use healthy bulbs separated from a harvested cluster or bought for planting. Plant them in spring as soon as the ground is workable; autumn planting depends on the hardiness of the material and your climate. Choose sun and loose, fertile, well-drained soil, without fresh manure or standing water.
Place each bulb roots down and pointed end up, planting shallowly so the tip remains at the surface. Leave about 20 cm between bulbs and 30–40 cm between rows to give new clusters room. Adjust spacing to the grower’s instructions and do not earth up the bulbs.
If you use a pot-grown plant, replant it at its original depth without burying the base of the leaves. Water to help it establish, then during dry spells, without soaking the soil. Bulb planting does not require transplanting at a four- or five-leaf stage. In a pot, allow enough width for multiplication and ensure water can drain away.

Weed
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.
