@buildtomade: I probably should’ve just let the magnolias grow freely above my bermuda grass, but I was set on creating a future flower bed. When my son was two (he’s five going on fifteen now), I spent almost an entire year trying to eliminate that grass. Around that time, I also had the "brilliant idea" to build a landscape border with 4x6 pressure-treated lumber. After having heavy 10-foot timbers delivered, I quickly realized I might’ve bitten off more than I could chew. If you’re determined to tackle a similar project, here are a few helpful tips: Dig your trenches carefully: Aim for 7” deep and 6” wide, leveling thoroughly. Line trenches with landscape fabric to keep weeds at bay. Add crushed stone or gravel beneath the timbers to prevent rot. Let the wood dry properly (below 15% moisture) before staining and don’t forget to stain the ends! Drill ½-inch holes into timbers and anchor them firmly with 3-foot rebar stakes. Stack layers securely using structural screws. Finish with a pressure-treated top cap; mitering the corners gives it a polished look.
