I don't like nettles, because touching them hurts.
But I love all other weeds. Most of them are adorable little plants and they're always welcome in my garden and my pots.
Oh, this question resonates with me because I am the weeder on the flower farm. I am pretty certain that I am the only one who likes to do this task. I can spend hours listening to my music and weeding. Other spend about ten minutes with me and have had enough.
Claudine, you sound like you have such a sweet heart by allowing most of your weeds to be welcome in your garden. For us to allow this happen would be a big mess. Out int the field, the weeds will grow faster then the flowers starting to blossom. The weeds block the sun, take away the nutrients, and are a haven for snakes.
But, oh I hear you, when it comes to thistles! I always scream aloud, ouch! I am so thankful, right now, the thistle are young, thus no thorns, yet! I feel like I am in a race against time. Soon enough, they will be out in full force.
