Ooh, very pretty. And the primulas at the back look better than mine so "leave well alone" is a good gardener's motto.
Sadly, left alone, bindweed can strangle the world!
Bindweed is the bane of my life! Sadly my one and only next door neighbour does nothing to her garden, it is a complete tp and bindweed and brambles come over from her side. The brambles I just cut back to just her side of the fence, but oh the bindweed! I dig it, put that selective weed killer on the leaves, wage war on it all summer long but getting rid of it while it is rooting and spreading her side is impossible.
Tell you how bad her side is. We had someone doing some work on our flat roof at the back and he asked me if we had gypsies living next door because of the rusting cars, old caravan and general junk lying around in there.
