Nettles for butterflies
Can anyone advise me when is the best time in the growing season to cut back a nettle patch? The nettles grow along the river edge on our housing development and many residents like to see them cut back in the summer so they can see the river. I read in the August Gardeners World that nettles are important for butterflies at each stage of their life cycle so I worry about harming the butterfly population by random cutting. As the nettles do need to be controlled I want to make sure that we do the least amount of damage to the butterflies by finding the best time to cut. Any advice would be much appreciated.
