We are about to purchase 10 acres in Newaygo County, Michigan. I've been wanting to plant chestnut trees mainly for deer, I doubt 10 acres is profitable for selling the nuts. I realize cultivars are the way to go but which tree would be best and where can I purchase them. It's now 09-20-2018 so I believe I can still plant trees. Any help would be appreciated.

Austrian Pine - Spray or Inject?

Our two mature Austrian pines have diploidia, but they have continued to thrive with bi-annual injections of a product called Sheppard's. We recently got a tree-maintenance bid from a company that claimed that spraying an "insect/disease treatment" would be comparable to the injections. This is the same spray that would be used on various deciduous trees on our premises. I have always understood that injections are the only effective treatment for diploidia. What do you say?
