Getting rid of onion grass

[SpicyPear]

It's my first foray onto Gardening as I'm a complete novice. I wondered if anyone would be able to advise on my onion grass problem.

Last year I dug out a long bed that runs between our lawn and the fence, on the basis hubby would then seed it to extend the lawn. Except he didn't

So now it is covered in what I've worked out is onion grass. I had an experimental dig in one part and there were hundreds of the tiny bulbs that they grow out of.

I'm guessing if we seed the area it will continue to keep coming through unless we've completely eradicated it. How should I do this? I also have dogs and I'm concerned about them eating it as onion is poisonous and I'm assuming this is too. Many thanks if you can help a gardening ignoramus

What country do you live in? Onion grass isn't native to the UK.
If you are in the UK there are lots of other thing that it could be, like dwarf hyacinths.

I'm in the UK. I googled it and onion grass sounded just like it, but might be something else then. Looks like tall grsss, white bulbs when it has sprouted, which are brown and pebble like before, very strong oniony smell.

Is it chives? We've got tons if them in our garden.

sounds like chives to me too - are the fronds hollow inside, OP, like little tubes?

Not hollow, more like grass fronds. Chives was my first thought because of the smell but I don't think so. I've had another mooch around the Internet and am wondering if it's wild garlic, which we do seem to get in England.

Really wishing I'd paid more attention when DF and DGF tried to get me interested in the garden as a child

We've got wild garlic too - it's very coarse?

Hmm, well i think the taller bits could be described as course, yes.

I think they might be spring onions, we have wild ones in our garden and they are annoying. I keep on pulling them up as they are in my flower bed but every year they come back :(. this year as the weather has been milder they are growing earlier than usual. You could either pull them up or you could use round up which will neutralise when it hits the ground. I tried a thick layer of mulch and they still come through but it might work better if you put a plastic membrane down first.
