How should I plant my fruit trees?

Question

I have a Dwarf avacado tree, Meyer Lemon tree, Washington navel tree, and stella cherry tree, each from 5 to 10 gallon each. My house faces to the east. From east to west is how I want to plant my trees, which has a spand of 50 feet from wall to wall. The other spand from North to South where I am planting the trees has a 10 feet spand. (I also bought root barriers for this).
- Starting from the East side (which is where the sun hits the hardest) which tree should I plant first, and second, third, and which tree should I plant towards the west side?
- On the barriers, which has a depth of 18", is there a certain technique?
Thank you..

Answer 1

Early morning and late evening sun rays are not nearly as powerful as midday sun rays. So, your premise of an east-west alignment based on the the hardiness of the trees makes no sense.

I'd plant the trees based on their growth characteristics, height and circumference of branches [mature drip line].

If you want the best view to be from the street, I'd plant the smallest tree further from the house and the largest closest.

If you want the best view from the house, then reverse the order.
