Choose a location with at least 6–8 hours of sun and good drainage
Select dimensions (common: 4 ft x 4 ft x 10–18 in) and plan for access from all sides
Pick materials suitable for outdoor use (untreated rot-resistant wood, cedar/redwood, composite, or rot-resistant lumber)
Gather supplies and tools (level, tape measure, screws or exterior bolts, drill, hardware cloth or landscape fabric, soil/compost, shovel, gloves, wheelbarrow)
Check local rules for bed placement and materials
Clear the area of grass and debris
Measure and mark the bed footprint
Level the ground where the bed will sit
Build the frame using exterior-grade screws/bolts
Add corner supports or internal bracing to prevent bowing
Install a bottom barrier if desired (hardware cloth for pests; landscape fabric to reduce weeds)
For pest control, staple hardware cloth to the bottom and sides (leave no gaps)
Place the bed frame on the leveled ground
Secure the bed by anchoring stakes/posts if needed for stability
Fill with soil in layers:
Optional: coarse drainage layer (only if needed for your soil)
Add quality topsoil mixed with compost
Top with compost or a final layer of enriched soil
Use a soil mix suited to your plants (typical: compost + topsoil, optionally with peat/coco coir and perlite if you prefer)
Leave 1–2 in of space at the top for watering and settling
Firm the soil lightly without compacting
Water thoroughly to settle the soil
Refill as needed after settling
Plan irrigation (drip line or soaker hose recommended) and install before planting
Add mulch on top after planting to reduce evaporation and weeds
Plant using spacing appropriate for the crop
Maintain with regular watering, weed control, and seasonal compost top-dressing
Refresh soil or add compost each growing season as needed
