Frequently Asked Questions: Raised Bed Gardening

What is the best size for a raised garden bed?

The most practical raised bed size is 4 feet wide by 8 feet long, with 12 inches of depth. The 4-foot width lets you reach the center from both sides without stepping in. Deeper beds (12–18 inches) allow root crops like carrots and tomatoes to thrive without hitting hard subsoil.

What should I fill a raised bed with?

The classic raised bed mix is 60% topsoil, 30% compost, and 10% perlite or coarse sand. This gives good drainage, nutrients, and structure. Avoid using only compost (too dense when wet) or only topsoil (compacts over time). Refresh with 2 inches of compost each spring.

How deep should a raised bed be for vegetables?

For most vegetables (tomatoes, peppers, beans, lettuce), 12 inches is enough. Root crops like carrots and parsnips need 18 inches. If you’re building over concrete or compacted soil, go deeper to avoid drainage issues. Shallow beds (6 inches) work for herbs and leafy greens only.

Do raised beds need drainage holes?

Most raised beds are open at the bottom, which provides natural drainage. If yours sits on a hard surface (patio, deck), add drainage holes or use a fabric liner with holes. Check drainage by watering heavily and watching — water should not pool for more than 30 minutes after a good soak.
