Why Raised Beds Win in San Diego
Raised beds warm earlier, drain better than compacted clay, and let you control the mix. Keep width to what you can reach from the sides so roots stay uncompacted.
Materials Required
- Untreated redwood or cedar (avoid painted scrap near edibles)
- Corner hardware, level, drill
- Vegetable raised-bed mix (inspect bagged soils — no legal garden-soil standard)
- Compost for top-ups
- Mulch after planting
Step by Step
-
Pick sun and access
Most vegetables need about 6–8 hours of sun. Place the bed where you can reach from both sides without walking on the soil.
-
Build to reachable width
Aim about 3–4 ft wide if you can work both sides (≤3 ft from one side). Depth ≥12 in for most crops; deeper helps tomatoes.
-
Use safe lumber
Prefer redwood or cedar. Skip painted wood near food crops. Metal troughs need drainage openings or an open bottom.
-
Fill with a real vegetable mix
Ask for a mix made for vegetables in raised beds. Blend thoroughly; break clods. Avoid dumping random yard soil that may carry weeds and disease.
-
Blend at the base, then plant
Roughen native ground and mix a little into the first inches of fill so you do not create a sharp layer that blocks water. Water in, mulch, and plant.
San Diego Tips
- Top up with about an inch of compost each year as organics settle.
- Inland yards cook soil surfaces — mulch is not optional in summer.
