Help, need advice on with saving tree for shared root system

[JD3000]

My concern was roots that have grafted and potential entry point for a root/butt rot pathogen though I'll admit to not being familiar with this species.

Agree on leaving the future stump alone if that is to be the deaired course of action.

Are roots near a foundation or other hardscape a concern?

Cut it flush and spray the stump with sealant or leave it open?

Leave it open. Wood decay and dying roots are all part of the natural cycle.

Guy, the green line is the shape of the tree to be left, the red line is the shape of the tree to be removed.

Agree with rethinking this removal. Does the owner like groves, or specimens? 2-year timeframe, or 20? That would determine the objective.

What does the green line around the crown indicate?

If the laurel oak near the house has roots that are concerning, why not prune them?

The green crown indicates canopy of the 18" darlington oak discussed in item 3.

The laurel oak is a different tree not shown in these photos, It's canopy encroaches on the side and roof of the house. It is a two story home and the laurel oak was planted less than 5 feet from there side of the house. Nice tree / poor location

My home and the trees being discussed in this thread are located near the NC/SC state line less than 3 miles from the Atlantic coast; which is the reason I removed all of the trees that could/may fall on my house. I still have 8 acres of hardwood forest.

When Hurricane Matthew came through last year I thought I was in good shape having installed a whole house generator and being on a well. The top blew out of a big pine, landed on the side of my well house, damaged the generator feed and broke all of the piping in the well house. We were without power and water for a week. The well house and generator are located 150' from the house.

The owner is currently getting second quote for removal and pruning of the trees in accordance with the report. He has received permission from the HOA on the removal since he will still have three trees in the front yard.

I would like to thank all members for their input, my primary concern was preventing decay and bacteria in the root structure of the remaining tree.

Thanks; the green line looked like a spec for reduction pruning, is why I asked.

The remaining Darlington oak looks pretty close to the house. That species ime (there are several in Raleigh) can get heavy-ended and break in ice and wind. Removing the adjacent tree increases exposure, and risk of such breakage.

I manage a lot of trees <5' from houses by root pruning, but they are better species and have high value to the owners.
