Weeds In Bought Compost

I use bags of expensive compost every year and have noticed my garden is now covered in one type of weed which I don’t recognise but it is everywhere. I had a bag left over from last year and where the bag was torn these weeds were growing from the holes. My question is can bought compost contain weed seeds?

It can, but typically a properly turned and heated compost won't contain any seeds. You can use boiling water to kill them off without harming the soil, though.
