Propagation of Welsh Onion:

Seed - sow spring in a greenhouse. The seed germinates over a wide range of temperatures, it is faster at higher temperatures. Prick out the seedlings into individual pots when they are large enough to handle. When well-grown, the plants should be ready to be planted out in the summer. If they are not large enough at this time, grow them on in the greenhouse for their first winter and plant them out in late spring. Division of the plants is very easy and can be done at almost any time of the year though the spring is probably best. The divisions can be planted out straight into their permanent positions if required.

Cultivation of the herb:
