I planted out a load of seedlings, and because our weather here is currently 35-40C daily I bought some treated pine logs (anti-termite) and shadecloth and put up temporary shading for the vulnerable little plants. It's working, but even 2-3 hours of sun is enough to fry them.
So far I've planted out cucumbers, corn, dwarf beans (several varieties), zuccini, lettuce, tomatoes, capsicum and a few other bits and pieces.
The other problem here is the 'soil' across most of this area is 100% sterile grey sand. I've spent a small fortune adding compost, clay and other soil improvers, but the only real solution would be a big front-end loader and a truckful of good earth. Since that's not going to happen, I'll persist. I've managed to get a couple of beds into growable condition, but there's 500sq/m to go.
