Why is my “Blue Dwarf Japanese Stone Pine losing it’s needles?
I planted it this spring, following directions. I have a water meter to make sure it is not too wet or too dry. The soil is alkaline. Yet it is shedding needles at the base. Also, can I prune a few branches ? (By the way, it was expensive )

Usually, they will only tolerate slightly alkaline soils. Too alkaline, and you can expect to see the symptoms that you are experiencing now. I would add a little iron sulfate to the area around the tree. That should help it out. Follow all instructions on the package for the best results.
