Material

Lärche: 200-400 € Material für 1,2×2,4 m. Cortenstahl: 300-800 € (modern, rostfrei). Stein/Gabione: 400-1.000 €. Fertig-Hochbeet Holz: 150-400 € (Baumarkt). KEINE behandelten Hölzer oder Bahnschwellen für Gemüsehochbeete!

⚡ CalcWolf Insight

A 4×8×12" raised bed requires approximately 1 cubic yard of soil mix. Filling it with bagged soil from a hardware store (at $5-6 per 40-lb bag) would cost $150-180. Bulk delivery from a landscape supplier costs $55-65 for the same volume — a 60-70% savings.
