This might be a dumb question but I'm getting sod put down in most of my yard but I'm carving off an nice chunk for a vegetable garden. I don't want the sod growing into the garden so I was wondering if there is a physical barrier I can put down to prevent the grass from invading the garden. I've seen some material but I'm not sure how well they work or how deep they need to be to be effective.

Anyone have any suggestions or specific material that works well for this kind of application?

I have used only a few kinds of physical barriers, and have never been pleased with any of them. I have seen beautiful gardens and they mostly just edged the grass. I have some beds still with the roll black plastic, but the ends pop up, and I can never get it straight. I will be doing away with those slowly. So I am no help with suggesting a good physical barrier.

I have used a nice green metal barrier sold by Lowe's in the past. Now we just have a bare strip cut by the weedeater as a border.
The barrier didn't seem to work as well as the bare strip.

Lawn edger is obivious descision. And I don't understand, why does people here don't understand it. OP, lawn edger can help you to solve your problem. This isn't a rocket science. For example, I had a same problem as you 2 years ago. I had a problems with choosing a lawn edger too. But both of my problemes were solved after one of my friends showed me one review. There I've found best tool for cutting tall grass in whole world. Well, maybe not in WHOLE world exactly, but it's good enough for my lawn and garden.

I've been using a half moon edger, created a trench which is about 1 1/2" wide at the top, v shaped. Tried everything else without much luck, refresh it 2x a year, spring and fall.

To prevent grass from entering in the garden you can use following tips-
1. Add edging to your landscape design. It will create a physical barrier between lawn and vegetable garden.
2. Dig a trench to create soil-free space between lawn and edging. It won't allow grass seeds to enter your garden.
3. If edging and trenching techniques are not showing results, use mulch to create physical barrier between lawn and garden.
4. Mowing is the best option to prevent grassroots to enter your garden. Mow the lawn around the age and save your garden from grassroots.

Neither do I like lawn edging or black plastic. I have daylilies in front and back of a black board fence, and this area is bordered by grass.
I dig a deep trench below the grass roots and extending about 12" beyond my plants' base.
I then fill the trench with mulch and mulch the plant.
The last step is to work Preen into the mulch as directed and water it in.
This process usually lasts two years for me before I need to tidy up or re-dig the trench.
Of course, I replenish mulch and preen yearly as needed.
