Had this garden for a year now totally untouched for a number of reasons There are some nice plants worth saving but the majority of the front & back gardens are completely covered in bindweed knotweed Do I start trying to dig it out now. Cover it with black plastic & hope that it dies off. Give it a powerful blast of some kind of weed killer, I am not adverse in one-off extreme conditions such as my present one. Or what other effective solutions are on offer? Back garden is about 120 x 40 ft.
I should be very grateful for advice. Thank you.
