Hi, I have never grown anything in my life, but now have a rather large (roughly 6m x 4m) balcony/patio area and woud like to try my hand at a few easier veges. North facing, in Canberra - I might need to protect with shade in mid-summer. One issue I am finding is that balcony pots and elevated beds tend to be quite small - some interlocking small ones are around but expensive. Does anyone have any receommendations for larger lighteweight beds suitable to tiled surfaces, and easy to grow vegetables? I know I am a bit late in the spring for a lot of planting, but that's fine. if nothing much grows this year, no great loss - I wouldn't expect to get things right first go anyway.
