Raised bed-how much top soil is needed?

[Diva1983]

Hi folks,

reality has finally hit me that if I want to have fresh veggies this year I need to get my skates on so I'm on the mission to sort out my raised beds (that I'm building myself-shock, horror!!!).

I was wondering if others have any hints and tips on building/filling raised beds? How do I figure out how much top soil I will need? Is their a formula I can follow based on the size of the bed? How deep do the beds need to be?

I'm considering three beds. One for salad and herbs, one for general veggies including carrots and another one for spuds-although I am considering growing spuds in containers too

If there's any good websites with 'how to build' guides on please let me know so I stop chewing eveyones ears off

There is an article in the february GYO mag about lasagne gardening, and a thread on here about it. Might help.
