How deep should my raised bed Be for veggies ?

I am putting in 3, 12 inch deep raised beds on the ground to plant veggies in. I will be mulching around the bed and want to put landscape fabric under the mulch should I put it under the beds as well or will the roots of my veggies need the space? Trying to keep weeds out of my beds

Allow adequate soil depth for the plants you want to grow. Many vegetable plants have root systems that go deeper than 12″. I would discourage putting in the fabric at the 12″ depth. It is unlikely that would do much for preventing week growth, and it may restrict root depth for plants that draw water and nutrients from the deeper soil profile. This article may help:
