Pruning welsh onion — FAQ
When should I prune welsh onion?
Cut leaves as needed through the growing season; remove flower stalks as they appear in spring or summer. Use clean scissors or a knife to cut individual stems to just above soil level. For ongoing harvest, take no more than one-third of stems at a time to maintain plant vigour.
How often does welsh onion need pruning?
As needed during the growing season; deadhead flower stems promptly if leaf production is the goal. Welsh onion needs minimal pruning. Harvest outer leaves by cutting them to about 2–3 cm above the base to encourage fresh regrowth — the plant is perennial and will re-shoot. Remove any flower stalks promptly if you want to extend leaf production; once it flowers, leaf quality declines. No other pruning required.
