Welsh onion

Allium fistulosum

Product Image
The leaves of this decorative 'cut and come again' Welsh onion can be used in a similar way to chives (although their flavour has a bit more of a kick), while the shoots (which are not as pungent as onions), taste delicious when added to salads. Simply cut off what you need at the base, and new foliage will soon appear to replace it.

How to care for Welsh onion:

Choose a sunny or lightly shaded spot with well-drained, fertile soil. Water regularly to keep the soil evenly moist and feed every few weeks with a balanced fertiliser to encourage steady growth. Mulch around the plants to retain moisture and suppress weeds.

Harvest leaves as needed by cutting from the outer shoots, which allows the inner shoots to keep growing, or lift whole clumps in autumn if desired. Trim any yellowing or damaged leaves to maintain plant health.

Sowing instructions:

Choose a rich soil in sun or part shade and sow sparingly into shallow drills in spring. Cover lightly with more soil and water well. Can also be sown in seed trays full of potting compost: pot on seedlings as they grow and transplant outside allowing 10cm (4in) between plants. Keep well-watered and snip off flowers to keep plants producing new leaves.
