David’s Auria Arid Region Forestry Project near Minnivale, in the Western Australian wheatbelt, has planted nearly a million trees in trials that began in 2001.
Some of David’s techniques are counter-intuitive, but after a million trees, there is no question they work.
Just before planting, trays of trees are placed in water, until the root-balls are fully saturated. The trees are then planted with the root-balls 20 centimetres below the surface. With just a few leaves exposed, the transpiration rate and evaporative loss from the root-balls are reduced.
Contrary to expectations, the trees do not suffer from collar rot. They produce roots from the buried trunk in the same way that cuttings do. David also plants late in the year, after winter weeds have died off...
...Dead weeds are slashed and ploughed in, adding vital organic matter to the soil, stimulating microbial activity, and improving the heat-insulating and moisture retention qualities of the soil. Trees planted in this way, over the months from September to January, have proved to have outstanding survival rates, even when planting is undertaken on days when the temperature is well over 40 degrees celsius - and despite the fact that trees are never watered.
David says that watering destroys the insulating qualities of the dry soil that encapsulates the stems of the seedlings. If the trees are watered, the water on the surface evaporates away quickly due to heat, wind and low humidity, which then draws all the moisture out of the soil and root-balls via capillary action. Belts of trees reduce evaporative loss from sheltered crops while elevating the humidity of the air – both of which benefit crop yields. David advises planting as wide a diversity of species as possible, always including eucalypts, melaleucas and acacias, to create more effective windbreaks while capitalising upon the symbiotic relationships that exist between them.
In the infertile soils of the arid zone, planting a diversity of trees in a shelter belt minimises competition between them for scarce nutrients - another important factor in survival and growth rates.

I just read "David advises planting as wide a diversity of species as possible, always including eucalyptus, melaleucas and acacias".
So basically he plants native Australian species, but I and I think Abraham also, are interested in fruit trees. I already have over 500 eucalyptus that I consider weed on my property and I want to eradicate them. It grows super fast, when cut to the ground it will regrow 3m per year. Not bothered by drought, freezing, wet mud of winter, nothing. I'm cutting them now, because the weather is perfect for such a heavy labor.

Abraham said, "thyme, fennel, and rosemary. Good for spices, little more.
These also have medicinal benefits, too!
I use rosemary for mouthwash.
Here is a thread to offer suggestions on how to water your trees and plants:

I was intrigued by your post because I am living in Croatia and we started to have the same problems as guys due to the climate change.
I have read a numerous articles and Youtube videos on that matter, but then I came across with Hugekultur techniques.
If you didn't tried already , maybe you could give a shot.
This technique seem to me very promising, at least for edible plants, shrubs and small trees.
