how deep to grow vegitbles, what is the best method ,any advice .



As far as I know 60cm depth is enough for nearly any type of planting. This may come to a suprise to many people.

You see after 60cm depth, the soil becomes too compact and lacks oxygen, therefore worms and other microbs cannot thrive at that depth, the soil is compact and lifeless, so it's very seldom you get roots penetrating this depth, although some trees do send there roots down to depths of up to 2 to 4 meters however these are just one off roots and not the entire rooting system, and you only want it for vegetables right, so 60cm depth would probably be actually too much so I'd aim for a depth of at least half that anyway, maybe a little more, between 60cm and 30cm I'd imagine would be sufficient for a vegatable crop.

Hope this helps you.
