This is a straightforward record of one conversion: a rectangular 900-square-foot front lawn, full sun, clay-loam soil, converted to a mixed perennial border over eight months without a full sod-cutting crew or a landscape architect’s fee.
We sheet-mulched instead of removing sod: cardboard laid flat over the mowed grass, overlapped by six inches at every seam, then 4 inches of wood chips on top. Watered in immediately, it needs about ten to twelve weeks in a growing season to fully smother turf. It’s slower than sod-cutting but costs almost nothing and improves the soil underneath instead of stripping it.
The new bed followed the existing walkway curve rather than a straight property line - a shape staked out with a garden hose and adjusted over two days before any cutting happened. A curved bed reads larger than a rectangular one of the same square footage and gives sightlines from the porch instead of one flat wall of plants.
Roughly 60% of the bed went to three repeated structural perennials (Little Bluestem grass, Purple Coneflower, and Black-Eyed Susan), spaced on 18-inch centers. The remaining 40% was left for seasonal filler and spring bulbs, planted the following fall once the structural plants had a full season to establish.
Total material cost, not counting labor, ran under $600 for the full 900 square feet - most of it in wood chips and plant plugs rather than mature container stock. By month five the bed needed watering only during extended dry spells, versus weekly mowing and irrigation for the lawn it replaced.
