What soil for trees?

we’ve we are building 2 x raised beds with sleepers to plant a selection of small trees we have including flamingo trees, small cherry blossoms, some small Japanese acers/maples and a forsythia.  What sort of soil or soil mix will we need to order? 

Normal top soil, ericacious top soil, compost or a mix?   
Are there any specific do’s or don’ts I might if overlooked?

    Normal top soil would be my choice.
    There is nothing there that would need ericacious.
    That's a lot of root for your planters.so have good spacing.
    2 there will need consistent watering. You might want to have some sort of irrigation system even if it's only plastic pipe drilled with holes set into the soil so you can get water down to the roots.
    One thing springs to mind is that they are all deciduous so you will have bare trees for 4 - 5mts so choose some with a good shape of branches with this in mind.

    Belated thanks twoPenny, planters are going to be 4 fence panels wide by about 80cm depth 9front to rear, not height), and the smaller one will be 2 panels x 80cm depth

    May I ask what 2 will need a lot of water?
