Soil Recipe for New Raised Vegetable Beds

A gardener building 4×24-foot raised beds with 8 inches of topsoil over plastic asked for a "recipe" including blood meal and lime. The answer: there's no universal recipe without a soil test.

Why Soil Testing Is Essential

• Lime raises pH; amount depends on current pH and soil texture.
• Blood meal is high-nitrogen (12-0-0); suitable for leafy crops but excessive for fruiting vegetables.
• Phosphorus and potassium needs vary by crop and existing levels.

General Guidelines (Pending Test)

1. Target pH 6.5 for most vegetables.
2. Incorporate 2–3 inches of compost or well-rotted manure into the top 6–8 inches.
3. Use a balanced organic fertilizer (e.g., 5-5-5) at planting, then side-dress with nitrogen for leafy crops.
4. Replace plastic with porous landscape fabric to allow drainage and gas exchange.

Where to Get a Test

Your county extension office offers affordable, detailed soil tests with crop-specific recommendations. Independent garden centers often provide free pH testing.

Invest in a test first—it saves money and prevents nutrient imbalances.
