Raised Bed Gardening Guide
Raised beds solve almost every common gardening problem at once: poor soil, drainage issues, weeds, and back strain. They're the most beginner-friendly way to grow food, and they look great in any yard. Here's everything you need to know to build and plant your first raised bed.
Why Raised Beds Work
- Better soil control: You fill the bed with exactly the right mix, regardless of what's underneath.
- Improved drainage: Elevated soil drains better than ground-level soil, preventing root rot.
- Fewer weeds: Raised beds start weed-free, and the elevation makes weeds easier to spot and pull.
- Less bending: Even a 12-inch height reduces strain on knees and back.
- Longer season: Raised soil warms faster in spring, letting you plant earlier.
- Higher yields: Better soil + better drainage + fewer weeds = more food per square foot.
Choosing a Size
The ideal raised bed is:
- 4 feet wide — wide enough to plant in, narrow enough to reach the center from either side
- Any length — 4x4, 4x8, or 4x12 are common. Start with 4x8.
- 10-12 inches deep — enough for most vegetables. Go 18+ inches for deep-rooted crops like carrots.
Materials
Common options:
- Untreated cedar: Naturally rot-resistant, lasts 10-15 years. The gold standard.
- Pine/softwood: Cheapest option, lasts 3-5 years. Good for experimenting.
- Concrete blocks: Durable, cheap, easy to assemble. Can get hot in full sun.
- Galvanized steel: Modern look, lasts forever, but more expensive.
Avoid pressure-treated lumber for vegetable gardens — the chemicals can leach into soil.
Soil Mix
The classic "Mel's Mix" ratio works well:
- 1/3 blended compost (mix of different sources)
- 1/3 peat moss or coconut coir
- 1/3 coarse vermiculite
This mix is light, drains well, retains moisture, and provides nutrients. For a 4x8 bed that's 12 inches deep, you'll need about 32 cubic feet of mix.
What to Plant
These vegetables do particularly well in raised beds:
- Tomatoes — one plant per 2 square feet, staked or caged
- Peppers — one plant per square foot
- Lettuce and greens — 4-9 plants per square foot
- Herbs — basil, parsley, cilantro in dedicated squares
- Radishes — 16 per square foot, harvest in 25 days
- Bush beans — 4-9 per square foot
Maintenance
Raised beds are low-maintenance but not no-maintenance:
- Water consistently (raised beds dry out faster than ground gardens)
- Add 1-2 inches of compost each spring
- Mulch to retain moisture and suppress weeds
- Rotate crops annually to prevent soil depletion
