Q.We Have 10 Newly Planted Oak Trees (bare-root) 6ft High Planted Late February. Don’t Look Like They Are Growing?
We have been watering them regularly and have a water irrigation loop installed, the leaves from last year are still on some of the trees. Do they not grow much in the first year after being disturbed.

This can be normal, to a degree. I would be careful with watering, though. It will only need water once the soil is completely dry down to about 2 or 3 inches. Overwatering is one of the most common reasons that a transplant will fail.
I would try removing the leaves, and giving the very tips of the branch a snip. Sometimes this can kickstart things.
