I have been meaning to respond to this thread for quite a while, sorry for the delay!
1. What is your general location, garden zone, type of soil, amount of daily sunlight?
Southern Hemisphere, south western edge of Australia, about 100 kms inland. The zones are a bit foreign to me, summers are very hot and dry, with temps of 40C/104F being the usual and cool wet winters with light frost. Annual rainfall is 730mm/28.74inches. Don't know exactly on how much sunlight, maybe 8 hours in winter and 14 in summer. But when in full sun it is VERY intense. I had to look up elevation - 258m/846.4feet. Basically a desert hole between a (very small) mountain range and the sea.
Soil type is just black sand. I am next to a major highway, so its sand as fill. No nutrients, full of broken glass and rubbish. Lacking all nutrients and trace elements, acidic and dusty. The tree beds were filled with real soil by the previous owners or nothing would have grown.
2. How long is your NATURAL garden season? (how long can you grow crops without microclimate adaptation)
Hmm "crops" is still a stretch for me, haha. Different stuff grows at different times. I am still figuring out what grows best when. I am more likely to lose plants over summer than I am over winter.
3. Do you have any natural, or man made climate extenders? What microclimate adaptations are working for you? What are you thinking of adding in the future? (could be season extenders in the cold north, or methods of protecting crops from excessive heat)
I have a few wire and shade cloth contraptions that I put over plants that look to be suffering in the heat. I will tie up a shade cloth in some areas for temporary cover. I'll cover seedlings with upside down pots sometimes.
Greenhouses with plastic covers have not been successful for me. The plastic disintegrates and the food comes out tasting like raw snails coated in plastic. Shade cloth seems to be a better option for me, allowing breeze through and can be wet down if need be.
My growing beds are strategically placed around the garden to try to get afternoon shade from surrounding trees.
4. What crops do well/thrive in your garden? What can't you grow?
Herbs thrive (most of them year round). I would like to get a larger collection going, but finding seeds can be difficult.
Spring onions and leeks grow most of the year.
Strawberries love it (and bobtail lizards love strawberries) starting a blueberry bush that looks very happy too.
Fruit trees also do well (grapes, apples, pears, lemons, mandarins. Limes are all year).
Kale, silverbeet, lettuce, all very successful.
Watermelons and pumpkins can do well, depending on the bugs that year.
Sunflowers will grow from Sept through to June.
Broad beans grow from May onwards. I have started some peas this year as well.
I have trouble with tomatoes but my neighbour grows them very very well, so I just swap stuff for his now. We do try to grow different stuff so that swapping makes sense. I dont do as well at capsicum or chillies as he does.
5. What diseases and insect pests are particularly damaging?
I am very lucky disease and insect wise here, as Australia in general is pretty clear of some of the worst out there. No fruit fly or bats where I am. Snails are the big eaters, but my ducks are keeping them under control quite well. Slater bugs and earwigs have become a problem for seedlings since adding mulch, so I need to get things well established in pots to start with. White moths can decimate the kale, they seem to ebb and flow with the weather. Caterpillars are around, but not in huge proportions.
Now, Bees are wonderful and I wouldnt call them a pest by any means, but they like to get drunk on my grapes. Had more than a few taking a nap in the bunches, biter beware!
6. What do you do for pest management? Any new ideas you want to try?
Ducks

They do a much better job of snails than the chickens did, and they dont dig holes! I will cover some plants at night if need be, but am really trying to move towards plants that are unappealing to my particular pests. Parsley, dill, carrots, lemonbalm, rocket, broadbeans, silverbeet go relatively untouched.
Birdnetting for the fruit trees is required. The nets also help keep the trees cool in summer.
I want to get a dog to try and keep the cats and rats away, but with the prices they are, it could be a long while off.
7. Till? No till? Mulch?
Mulch. Lots and lots of mulch. One of the first things my neighbour told me was to build UP the soil. Dont dig in. I highly suspect lead is the reason for that. So I just keep piling on the mulch and building up little beds as I go. The whole town is sort of sinking into salinity so despite how much I build it up, everything eventually sinks. Luckily I have the bunnies who provide plenty of mulch for me.
8. Intercropping/companion planting?
Yes, attempting to. Nothing touches the parsley, so I am dotting this all around the joint. Sunflowers are a favourite of mine as they provide shade and seem to love everything.
9. Soil improvement plan, and how has that worked for you?
Yeah, just building up and up with hay mulch and wood shaving litter from the bunnies. Any trimming from trees go in to help give some structure. I have a compost bin for weeds that need to die in heat and a compost pile for hay or larger stuff to break down a bit. The earthworms are some of the biggest I have ever seen in my life. Its amazing how quickly stuff turns to dust here, but I am seeing a MAJOR improvement in water retention over summer. I am on the lookout for clay catlitter as I think
@Britesea suggested but havent come across any yet, I think that sounds like a good idea for parts of my garden.
Ducks free roam in the wet months, free fertiliser, weeding and pest management in one! I move their paddle pools around to where I want some extra fertilisation or weed flattening.
10. Bird and mammal pests? Fencing?
Wild rabbits have been an issue in the past, but I did a lot of work in fencing off my whole property and this has been successful so far. I need to keep them out of my garden as I have house bunnies as pets and do not want them to get any of the man made viruses that are released locally into the rabbit population. Foxes have taken a few ducks before, by digging from under the neighbours fence but havent tried again for a while. Cats are everywhere and they drive me bonkers killing the lizards and frogs.
Its a grain town so I get mice and rats, unfortunately bait seems my only option for them. I wanted to do live traps and freeze them for the bird rescue but my mother forbid it haha. Venomous snakes are really the only kind we have and there are enough here already without me attracting them to a feast. Sorry
@Lazy Gardener you can keep your slithering critters! I love frogs though and have some great western spotted frogs.
Birds. Such a lovely variety, but they WILL eat everything sweet.
