Using block pavers for lawn edging?

CapabilityJones

I'm trying to spruce up my lawn a bit and a while ago I got some block pavers free from a neighbour (bricks with no indent so they're flat on all sides). I want to use them to make a border between my lawn, which is a rectangle, and the flowerbeds, as some of the flowers are trying to creep into the grass, and it's also hard to mow right up to the edge of the lawn.

I tried googling ideas but they suggested I should be laying the bricks into concrete. I live alone and the only real foot traffic would be my cat walking on it, plus me running the mower across it. Is concrete essential or could I just dig a trench to make them level with the lawn and then press the soil in the flowerbeds right up to them? I'm not keen to do more than I really need to - I also don't have a garage, just a very small shed, so I don't have a lot in the way of tools or areas to work in. Some of the guides say things like mix the concrete on a board so you don't ruin a paving slab etc but I wouldn't even know what to do with the leftover concrete, nor do I have spare boards or trowels and so on! 

Can I just lay the pavers in the earth? How bad would that be? A few articles suggested they'd move 'eventually' but didn't really say if that was in weeks or years.

You can lay them in the earth; but they will move over time.   It wouldn't be neat in the long run, but it may be sufficient.

Could you get hold of bags of sand and lay them in that? Sand presses more level and therefore might look neater and less likely to move

Just move the hi just move the plants that are creeping forward back a little. Use an edging iron to cur a nice sharp edge.... Then you can mow straight over the edge rather than cutting up to the bricks.
or lay the bricks as said on sand slightly lower then the lawn also gives you that edge.
Good luck... do love a nice lawn!

I've laid stone into soil and it stays for a year or two. You will get weeds coming up between though and they will move a bit as the soil dries or gets wet and the worms work away underneath.

But if it's just on soil that's an easy enough job to do and put right as needed
