Please help. I noticed this coming through my lawn when i last cut 2 weeks ago. now it is running rife. i'm not much of a gardener as you can probably tell
I'm glad to hear you're not a keen gardener ...... if you were this news would be soul destroying.
As you're not into gardening that's fine.
What you have there are the flowering/fruiting bodies of the dreaded Horsetail
Pull them up and bag them and put them in the bin.
