Converting half barrels into planters

Hello! We have acquired two half-barrels and would really like to convert them into planters, probably to grow beans/peas up some wigwams. At the moment the barrels have no holes, however are old enough that they are not completely watertight either. 

Questions:
1) If we want to plant straight into the barrels, is it best to drill holes in the BOTTOM or the SIDES? Our thinking being that the bottom would allow better drainage, but maybe the side (like 10cm up maybe) would allow better water retention in the base, to allow the plants to cope better when watering isn't so frequent. 

2) Is it worth the hassle of making them into self-watering/subirrigation style planters? We think we'd have to line them first to make them waterproof for the reservoir, but it would be possible, just not sure it's worth the effort.

Thanks all!  :)

    Just drill some fairly large holes in the bottom, should be perfect.

    As punkdoc says, drill the holes in the base. If you have water standing in the base of any pot, the plants will die. Good drainage is essential. This from the RHS:-
    "Waterlogging limits oxygen supply to the roots and prevents carbon dioxide from diffusing away. Root function is reduced or stops and the roots start to die off, allowing the invasion of rots and decay organisms. This has a subsequent effect on the visible parts of the plant, as the leaves and stems are unable to obtain enough water and nutrients."

  • Thanks so much! We have drilled some holes into the bottom and have now filled with (peat free) compost ready for planting up! Thanks again for your advice!
