You’ll appreciate how simple it is to make, using readily available ingredients that can often be sourced at garden centers or even from your own compost pile. Plus, making your own super soil saves money in the long run and helps reduce environmental impact.

It’s perfect for container gardening, raised beds, or any space where you want to grow healthy, vibrant plants.

Ingredients

• 8 gallons high-quality organic compost
• 4 gallons peat moss or coconut coir (for moisture retention)
• 2 gallons worm castings (rich in beneficial microbes)
• 1 gallon perlite or pumice (for aeration)
• 1 cup bone meal (slow-release phosphorus)
• 1 cup blood meal (nitrogen source)
• 1 cup kelp meal (trace minerals and growth hormones)
• ½ cup azomite or rock dust (trace minerals)
• ½ cup dolomite lime (pH buffering and calcium)
• ¼ cup gypsum (calcium and sulfur)
• ¼ cup neem seed meal or alfalfa meal (stimulates microbial life)

Equipment

• 5 gallon bucket or large container for mixing
• Shovel or garden fork for mixing ingredients
• Measuring cups and containers for precise ingredient amounts
• Gloves to protect your hands
• Moisture meter (optional) to check soil moisture
• Plastic tarp or sheet to mix on (optional)

Instructions

1. Prepare your workspace: Lay down a tarp or work in a large open area. Gather all ingredients and equipment for easy access.
2. Add base materials: Start by placing the 8 gallons of organic compost and 4 gallons of peat moss or coconut coir into your mixing container or bucket. These form the foundation of your super soil, providing organic matter and water retention.
3. Incorporate aeration: Mix in 1 gallon of perlite or pumice to ensure good drainage and air circulation in the soil.
4. Add nutrient amendments: Sprinkle in bone meal, blood meal, kelp meal, azomite or rock dust, dolomite lime, gypsum, and neem seed or alfalfa meal. These ingredients supply crucial macro and micronutrients.
5. Mix thoroughly: Using your shovel or garden fork, mix all ingredients well until evenly distributed. This may take 10-15 minutes to ensure a homogenous blend.
6. Moisten the soil: Lightly water the soil mixture until it’s damp but not soggy. Use a moisture meter or your hand to check — it should feel like a damp sponge.
7. Let it cure: Cover the soil loosely with a tarp or plastic sheet and let it rest for at least 2-3 weeks in a shaded, warm area. This aging period allows microbial activity to develop, making the soil more fertile and ready for planting.
8. Final mixing: After curing, give your super soil a final stir to aerate and ensure even nutrient distribution.
9. Use your super soil: Fill your 5 gallon containers or garden beds with this nutrient-rich soil and plant your favorite seeds or seedlings. Enjoy robust, healthy growth!

Tips & Variations

“For the best results, always use organic and sustainably sourced ingredients to keep your soil healthy and your plants thriving.”

You can customize your super soil to suit specific plants. For example, add more blood meal if you want a nitrogen boost for leafy greens, or increase bone meal for flowering plants.

If peat moss isn’t your preference, coconut coir is an excellent sustainable alternative that also enhances water retention.

Consider adding composted coffee grounds or crushed eggshells for extra nutrients. For an even deeper microbial boost, try mixing in some local garden soil or finished compost from your yard.

If you want to speed up the curing process, turn the soil every few days to aerate it. Just be cautious about drying it out — keep moisture levels consistent.
