You should use Hybrid HD Edging. It is much more than a standard aluminum edging, and it is far superior to plastic edging. Hybrid HD Edging is the only edging on the market that allows you to apply in both a dense grade and open-graded base. It makes a positive connection to the earth and has proven its strength, durability, and resistance to freeze-thaw susceptible environments. This means driveway edging that allows grass to grow, does not pop up over time, and resists lateral shifting even with vehicular traffic.
