    Howdy all,
    I am looking for some advice, we just had a patio laid with 600mm internal depth beds around it. The current discussion is what depth of soil we need to put into them. Hubby thinks we need to put some sort of filling in and then 300mm of soil but I think we can go the full depth without it becoming waterlogged. It's current base is compounded filling from when we built the house and water never rests in it. I am really hoping to vary the type of plants from large shrubs to seasonal bedding
    What would your advice be - 600mm or 300mm of soil

    It depends on what you are going to put in it. If you are going for shrubs then I agree the deeper amount would probably better. 30cm is fine for plants though.

    What would your opinion be on potential water logging in the beds - do you think that the 600mm would create more of an issue than the 300mm??

    Ah, I think you have an autocorrect there that was confusing me. Are you saying that the base of the beds is compacted? In that case I would loosen it a bit to create more drainage. It shouldn't really make any difference what depth of soil you have once the base is loose enough to drain.
