how to get rid of grass and put in retaining wall?

My mom has a really big back yard. Last summer she hire some people to do a concrete patio with cover. However, the dirt that was dug up was pour on to this part of the backyard. Now there are tons of grass grown on it. She has 4 large queen or king palm trees and a canary palm tree grown there. She dont want to harm the trees since they are thriving. She plans to get rid of all the grass, and put in some new fertilizer and soil and put in a retaining wall and trellis next to it. We have attempted to get rid of the grass before. It look fine for a month or two then the grass grows over it again. We already have the bricks. Is there any product or better method to get rid of the grass completely. There is two types of grass there. One is full of seeds but really easy to pull up. The other one is a pain in the a-- to get rid of. It has these really long fat roots that goes on forever. Don't really know where to dig up once it goes way under.
