Step 2

Work wood ash sparingly into topsoil (approximately 1 cup per 10 square feet, avoid if soil pH is already high)

Step 3

Apply seaweed extract or kelp meal according to package directions for immediate nutrient boost

Step 4

Spread granite dust or rock phosphate for long-term slow-release potassium

Step 5

Maintain 2-3 inch mulch layer to prevent nutrient leaching
