I'm planning the planting of nut and fruit trees this spring. I had envisioned a property with some slope but ended up with the flattest plot you can imagine. Under 2% slope from anywhere to anywhere. It is also considered borderline desert area. So water is an issue and collection and conservancy are important. I had planned on swales and berms but now I'm wondering - since it's flat does the direction of the swales matter? Does this free me up to design in any direction I want? Or is there another method I should use - digging circular swales around the trees perhaps to catch the winter precipitation ? Also, we're having more extreme weather and rainfalls and snows can be heavy though rare. The nearby river could flood as well - so managing floods is also a potential concern. There was also a brush fire on the hill off in the distance in the photo - put out quickly but I couldn't believe how fast it moved across the hill. Any thoughts from anyone? I'm concerned about keeping the trees alive, protecting them from the elements and getting them to establish without having to completely irrigate the site for years to come.
