Eventually there will be no lawn under a pine unless you remove the bottom 2/5 to 1/3 branches on the pine to allow for more sunlight. Removing the limbs is half the effort. You will need to remove the fallen needles from the lawn. Needles left on the lawn will also shade out the turf. This is advisable only if the pine is taking up to much yard space either functionally or visually. It is best to leave the pine with all it branches to the ground, leave all the needles on the ground and buy more if you want to speed up the process of ridding the yard of left over lawn.
I'm sure there is a more technical answer...
All plants need light and water. Pine trees effectively shade the ground, shed moisture away by the action of the needles above, and have shallow roots that compete for the available water and soil nutrients underneath it. Add to this the "shedding" of the dead needles that act as a mulch covering the ground below them.
yes
Grass
There are4 some trees that grass can not grow under. The roots from hickory trees is strong an consumes the ground around it along with its nutrients.
instead of buying them look on or under a pine tree for them - OR - you can go to a garden store and buy a pine seed wait for it to grow fully and pick pine cones from that !
You water and fertilize it

NO. The pine tree only grows in places that have cool temperatures.
