As a suggestion :For a $5.oo tree, plant a $10.oo hole with nutrients.
Not just a hole, but enrichen the soil, and make a pyramid of soil in the hole to spread out the roots of the fruit tree.
The soil pyramid will help spread out the roots, and assist in forming rootlets which will encourage an expanded dripline, as well as support the tree as it matures.
If they are grafted fruit trees, never plant the graft below the topsoil.
Thanks for the advice. Forgot I needed supports. Spent today digging holes. Tomorrow I’ll shop for amendments. Orchard will be on a gradual hill so I’m thinking a rock embankment on at least one side of the holes I’ve dug. I have two cherries and read they especially don’t like to have damp feet. Planning on planting them in raised beds with rock borders.
