It filled dozens of acres between two spurs of bald, grassy earth that drooped down toward the city. The ground in the little valley lay flat in spots, heaved up in others, the whole of it covered by the old growth of fruit trees and two or three times grafted branches.
How would you explain this sentence: The ground in the little valley lay flat in spots, heaved up in others?
Does this sentence mean that the valley was a group of terraces?
By the way, what does "the old growth of fruit trees" mean?
Does it mean these fruit trees were old?
Thanks
