Vanderwolf Pine Interior Needles turning yellow and shedding #159102

We planted a Vanderwolf (sp) Pine this spring, it was 6 ft. tall and has grown several inches this summer. But now its interior needles are turning yellow and dropping. The drip system goes 4 days a week (am & pm) and runs 10 min. each, out of 2 gallon drips and there are 4 drips to that tree. The rest of the yard is gravel and trees/shrubs, so there is no grass. The tree is in the Southeast corner, 5ft away from the block fence.
Is this normal? Am I over watering for this time of year?
Thank you so much for your input!

This looks like normal seasonal needle drop. No action needed.
Needles of limber pines, including 'Vanderwolf', live for 5 years before dropping. So every year you will see yellowing and drop of the oldest, innermost needles that have reached 5 yrs old.
Your pine looks like it may be in a heat-loaded spot (gravel, masonry wall, exposure). It will be helpful to water the rooting area during dry warm snowless periods in winter, in addition to normal seasonal watering.
