You want to use a soilless container mix. Do not go cheap. That will cost you more in
the long run.

My mix:

BX pro mix. About 2 to 3 cubic feet
2 50 lbs bags of composted manure
2 50 lbs bags of silica (play sand)
10 to 20 pounds of espoma plant-tone … good for the soil critters and it will not burn.
Make sure containers have drainage
If needed add in some miracle grow potting mix. No need for perlite or vermiculite.
Mix in a wheel barrel.

If the containers are large fill the bottom half with good clean straw and add your
planting medium to the top. The growing medium will migrate down through the straw.
