I had the first nettles. The first shoots are the sweetest. I always pick the top 4 leaves. There is sooo much uses for nettle and what’s good for.
One can dye with nettles, yellow roots, green leaves, and it is host to over 40 insects including butterflies and moths.
When you want to get rid of nettles mulch heavily. The next year the roots moved up and they are much easier to pull.
Fertilizer, chop and drop as its woody, fibre (link to utube video), paper, and of course as spinach, soup, with egg, tea, as well hair tonic and getting used to insect bites. As I handle them a lot making fibre I got immune to ant, bee, midget and wasp stings. Even horsefly stings don’t bother me much anymore.
Regulates milk supply, arthritis , spring clean. People wrote books just about the nettle.
