A yard with a steep slope can be difficult to landscape. Build a block retaining wall to add level tiers to your yard, which prevent erosion and provide a perfect place for a flower garden.
Engineering your retaining wall is the most important part of the process, as a well constructed wall should support hundreds of pounds of soil and plants. Proper drainage is vital to the long-term success of your wall.
Consider hiring a landscape architect to assist in design and planning. It’s possible that your expectations are beyond your DIY skill levels, which is always best to know before you start building.
You can buy retaining wall blocks at Home Depot for as little at 60 cents each, and spend up to $3 each for larger and nicer blocks. You’ll need a shovel, mallet, hand tamper, wheelbarrow, yard stick, level, and caulking gun.
Expect to spend a weekend or two to build this project. This Old House has a great video at the link below with in-depth instructions on constructing a block retaining wall.
