Q.Will A Large Pine Tree Kill All Plants Put Underneath It?
I have a 40+ pine planted too close to the house, however. That’s only one problem. It is a long needled pine, not aware of it’s variety, with huge hard cones, when they open, there are equally hard black seeds/nuts. I have never noticed any seedlings nor have have I noticed any plants surviving when planted under or even near it. Do I have a pine that should never been planted in the garden area? Giving thoughts to letting a chain saw at it-unless you have suggestions for plants that will survive. Susan Trapp.

Pines will kill most plants nearby, simply because their mess makes the soil too acidic for most things to survive.
My concern is that it is planted too close to your house. This is a hazard and needs to be removed, immediately, by a professional. Pines are notorious for falling apart as they age, so for the sake of your safety I would have it looked at.
