Chinese Pistache – Not Full & Lush

Question

My mature chinese pistache has a thin canopy… not full and lush. I know there is a bit of girdling roots (or more not sure how to check below the surface). I’m not sure how to help it… It’s a female and has a ton of the berry clusters… any suggestions will be much appreciated.

Answer 1

If you suspect root girdling, you may want to repot with fresh soil and fluff out the root mass a little. This will correct a girdling issue.

Otherwise, it could be multiple nutrient deficiencies if the soil has not been changed in awhile, or fed.

Here are some articles that will help:

Answer 2

Thank you so much!
I'll definitely read the first 2 articles, but as I said this is a mature tree...20 yrs at least. The trees4 dripline is roughly 40' across and the tree 25'+ tall. I have photos now but don't know how to share them without opening a new post. thanks again!
