That is a big oak you have there.

We just had to have an old oak removed this week...it showed rings between 150-180 yrs!

Oaks don't drop branches quickly when they die, as they give you
notice ..they will hang there for a while rotting. If you see any of these you should have them pruned off.

But they can be expensive to remove when they die...very expensive.
The nuts do hurt if they hit you squarely on the head though.
We've had our cars dented on the roof parked under our other big oaks. Our oaks tend to only make acorns every other year. We don't know if that is because of their enormous old age, or if that is just what big trees do.

Here is a photo taken on Monday of the old oak next to our home:

Old oaks may need special acidic fertilizer to maintain health as they rob acid from the soil ... they get poor leaves that don't green up well and that is called chlorosis. We had this oak treated with 2 iron peg treatments in the wood, and also some deep feeding of the roots. This tree was dying when we moved in around 1971, and we stalled the inevitable death until now.

They are beautiful stately trees though. You'll just have to weigh the pros and cons.
