Build raised beds to bypass poor native soil

Construct raised beds at least 10-12 inches deep and fill with a quality mix of topsoil, compost, and perlite or vermiculite. This creates an ideal growing medium from scratch, completely bypassing problem native soil.

Why It Works

When existing soil is extremely rocky, heavy clay, contaminated, or otherwise unworkable, amending it in place can take years. Raised beds give you immediate control over soil quality, drainage, and structure, providing plants a suitable root environment from day one.

Tips

• A mix of roughly 60% topsoil, 30% compost, and 10% perlite works well for most vegetables
• Beds placed on the ground allow roots to extend into native soil below
• Beds on concrete or asphalt need at least 18 inches of depth for root crops
• Plan for 1-2 inches of settling in the first season and overfill by 10-15%
• Higher initial cost but provides immediate results where in-ground amendment is impractical
