Here disease in uncomposted chips has never been a problem that I’ve heard of- and word gets around between landscape contractors. There are many plants in the northeast that convert fresh wood chips into shredded wood mulch and sell tons of it to landscapers that haul it away to mulch not only trees but perennial flower beds with it, some of it has time to age, some doesn’t so disease issues have to be very rare HERE.
Tying up N is seems only to become a problem in excessively wet soils where most functioning root is near the soils surface. It is something easily rectified with supplementary N.
It is possible where you are that there is a disease to be concerned about spreading through the use of fresh wood chips and if you aren’t sure you could contact your cooperative extension. They should be aware of any such issues in your state.
