Answer: There are two or three ways to broadcast grass seeds; one is to simply toss it out by the handfuls, criss-crossing the areas to make sure you've covered them all; another is to use a hand-broadcaster (plastic bin with a crank handle on it) and a third is to use a wheeled spreader. Sometimes you can rent the spreaders at garden centers. It looks similar to a fertilizer spreader.
Depending upon the grass seed type, you should have some sprout under the pines. Soil there is dry and acidic so grass isn't always successful, but it's worth a try.
Best wishes with your new lawn.
