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.
I've paid many hundreds of dollars for truckloads of dirt. Each one has has some near fatal flaw:
1. poisonous dirt that kills everything because it's actually decomposing shale
2. bluestone gravel and weeds
3. really bad weeds I'll never eradicate--crown vetch
4. such sterile fill that nothing grows in it AND it won't hold water
The one with excess gravel and weeds was the best of the lot. Add in all the bags of compost and manure and dirt and lime and whatever and I have spent easily two thousand dollars on dirt, with pitiful results time and again. When one figures in that I personally shoveled every ounce of the dirt from the dump pile or the bags to my gardens, they should have paid me.
