Planting 2 persimmon trees
We live on the mountain near George, Clackamas county, (but a bit further up) Legally in Estacada, but higher) 1. I purchased two persimmon trees through a catalogue. 2. They came without instructions. 3. They are about 1 1/2 ' high. 4. I have checked quite a few websites and they differ too much. 5. How best to plant them? How close? Even the depth of the hole differed. (1' or 5'). 6) Prune so they don't get too high or let grow? 7. How often to water? Thank you so much.

Thank you for your question about persimmon trees. Estacada is in USDA zone 8b, your area is (at least historically) appropriate for persimmon trees but if we have many more winters like last, it might be too cold for them, depending on the cultivar of persimmon you have. Here is a link to an Extension article about them with planting and watering instructions. (Although it is from a different state, the characteristics of the cultivars are the same, and you don't say what type of persimmon trees you bought.)
Here's an excerpt from an OSU Extension publication about their issues in Oregon:
"Persimmons: Some seasons in Oregon, there aren’t enough warm days for persimmons of either the American or the Japanese species to mature their fruit. American species, which are smaller and have seeds, will mature more often in our cool climate. Two or more varieties or seedlings of American persimmon must be planted for pollination. The Japanese varieties that will mature in western Oregon, such as Fuyu, bear seedless fruit and don’t require a male tree for pollination. Until they’re soft-ripe, most persimmon fruits are extremely astringent; Fuyu is much less so. The Japanese persimmon isn’t attacked by many enemies, and it’s a rather beautiful and useful tree for home plantings. Usually, persimmons are eaten fresh, but they can be dried. Place unripe persimmons in a box in a clean, dry place (such as a garage) for ripening."
I hope you find this helpful. Good luck!
