I’m not an expert but looks like bamboo no?

I agree with bamboo

That’s what I was thinking! Is it best to remove it? We’ve just moved house and there’s a lot of it in our new garden.

It’s a nightmare, the only way is to dig it up, it takes a long time as it spreads under the soil surface.
Some posters have had experience of killing it with weed killer.
