Q.Why is my “Blue Dwarf Japanese Stone Pine losing it’s needles?

Zone Amherst, MA. 01002 | shschill added on August 8, 2019 | Answered

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.
