Have your soil tested for pH and soluble salts. Since you have such a variety of soils on your property, a sample from each area would be a wise way to go. Your local Ag. Extension should offer the service for a nominal fee.

As a general rule, frequent watering encourages shallow roots, while deep and periodic watering promotes deeper root structure.

Hope this helps! Good luck.

The trees came from a big commercial tree farm that only deals with large companies, but will sell to locals.
They told me all they would need is ironite.
Two years ago I put in a yellow honey locust from Walmart...maybe 10ft tall, 1” trunk. I water it like crazy, feed it all kinds of stuff, and it’s gorgeous! It loves everything I do..and it’s in the same soil!
My New Mexico garden book suggests watering once a month until it get really hot...
