The Q&A Archives: Minimum Depth of Soil Required for Growing Tomatoes

Question: I am building a raised bed for vegetables, over an old gravel driveway. What is the minimum depth of soil that I need in the bed to grow tomatoes? Thank you. Peter Moran Slingerlands, NY

Answer: The minimum depth of the raised bed would be 12" deep. I've grown tomatoes in beds over asphalt that as 12" deep and had great success. Just keep them well watered and they'll be fine.
