Almost every house here has ornamental boulders and/or rock walls around their planting beds , driveways or yards. We don't have standard garbage pick up. If we did, I am certain that they wouldn't take rocks on bulk trash day. If you listed them on craigslist, everyone would think it was a joke.
It is hard to sink a Shepard's hook or a trellis support without hitting rocks over and over. Digging holes big enough to plant roses is considered "eccentric". Digging and perk testing the holes is worthy of neighborhood gossip.
Toni, 6" rocks are little rocks. I will take some rock pictures tomorrow for you. Guaranteed to hit at least one rock at least 6-8" digging. That would be a happy day! Actually, any day that the rocks I hit are small enough for me to safely move by myself without a moving truck is a good gardening day. a bad gardening day is when every place I dig is a rock to big to remove even with a bit of help. Depending on drainage, I either plant something less fussy than a rose or place a stepping stone in that location.
The 2-3" rocks help the drainage in clay areas. They are my friends. Areas around trees have several inches of good dirt from the decomposing leaves. I have some pockets of good soil in between the tree stumps.
Any hole dug ends up needing amended fill. First, to improve the soil quality. Second to fill in space formerly occupied by big rocks.
Think extra large bean bag chair sized rocks. Those are the huge ones. I work around those.
An auger won't cut it, maybe a really sturdy rototiller. (I am keeping watch on craitgslist). A backhoe would be better.
