Hi newbie here,
We bought our house at the begining of the year, the back garden is approx 1/8th of an acre which by all accounts has just been left to it's own devices for the past 35 years.
As I stepped outside this afternoon I noticed all of these leaves seem to have appeared from nowhere. Given the garden is so overgrown and we are tackling it as slowly and steadily as possible I am scared it might be the dreaded knotweed. I know someone in the neighbouring street has it on the boundary of a forrest and their garden.
There do not appear to be any flowers on it. It seems to have just sprouted in the last month or so I would imagine. There is a long branch like shoot which I have photographed and I was hopeful that this might be a tree or something (we had about 20 odd untendered trees which we felled).
Any help is desperately appreciated.
