Success without irrigation

You can bury old tree logs creating hugelkultur berms, as they breakdown, they act like sponges that tree roots can get water from (but not juglone containg trees like pecan, black walnut or black locust that have a natural pesticide.) The higher the berm, the less you’ll have to water. Something to look into to see if its a good fit.

I don’t have acreage, so logs won’t work for me. For years, I have put rotted wood into the hole when I plant a tree, along with gravel because of my clay. It works extremely well.
