Trimming large black walnut
I have a very large black walnut tree that was pruned about 20 yrs ago. I believe it several hundred yrs old and want to save it, but want to cut it back so it is not such a danger to the house (10 ' away). How far back/down can i cut it. It is about 30+ " in diameter at the base

I would recommend contacting a certified arborist and have it evaluated. The options for trimming may be dependent on how it was pruned previously and if it caused any long-term damage. You can find a certified arborist to contact at the below link!
