Directions: Stack a Flagstone Raised Bed

  1. Outline bed footprint with string; measure dimensions including wall height. Take measurements to flagstone supplier for quantity.
  2. Define perimeter with powdered limestone or gypsum. Excavate or add soil for level foundation; bottom stones set 1 inch below ground.
  3. Break oversize slabs: score line on both sides with chisel, place over scrap wood, hit with sledge. Set aside uniform square/rectangular slabs for top layer.
  4. Build bottom layer with largest, irregular slabs: straight edges out, jagged edges in. Keep each layer level; check with level.
  5. Stack subsequent layers, overlapping slabs to avoid vertical seams, filling gaps with smaller pieces. Angle wall inward 1 inch per foot of height for stability.
  6. Top layer uses reserved uniform slabs. Backfill with soil, tamp, add plants.
