Can grass grow under a pine tree?

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.
