Weedkiller control
Neglected areas can be cleared of established nettles by spraying them with a glyphosate-based weedkiller (such as Roundup Ultra or Doff Weedout Extra Tough Weedkiller) which should be applied as a spray in June, shortly before they flower.
A second application may be necessary in September.
