What is taking over my garden
Having been a keen reader of the forum the time has come to ask for advice. I am not a novice gardener but as you will see no expert either.
I moved into my house last year dug over the overgrown front garden. It was mostly lawn with some old perennials I noticed very few weeds. The soil is heavy clay so I laid a thick mulch of compost bought from a local supplier.
This year my plants are doing well but the whole garden has been invaded by the plant shown in my photograph. Not just a few but literally hundreds given it is a small Victorian terrace that is a lot of plants!! I am presuming my digging let loose the monster but what is it?
I did dig them out a few weeks ago but I now have a whole new crop. Has anyone any idea what it is and how best to remove it?
Secondly I was planning to mulch with bark in the next week but presume I should now wait until the "plant" has been eradicated.
Would be grateful for any advice at all.
