Small nettle patch for butterflies
I've got a small nettle patch that earlier in the year had small tortoiseshell caterpillars.
I've cleared some other stuff out the way today and exposed the patch and it is looking distinctly threadbare although some new shoots are coming through on the old stems.
I seem to remember reading somewhere to cut them back at some point whereupon they will grow back for a later batch of caterpillars. Is this correct/ necessary?
I started the patch in 2012 and would like it to thicken. I had been collecting the seedlings and returning them to the patch to speed up the process
