Adjusting SuperSoil for Optimal Growth

SuperSoil is formulated to provide rich, nutrient-dense support for a wide variety of plants, offering a well-balanced blend that encourages healthy root development, vigorous growth, and robust yields. However, some plant species may require specific modifications to optimize their performance, depending on their nutrient or moisture needs.

The following guide outlines how to adjust 1 cubic foot (1 cf) of SuperSoil for different plants. These adjustments may involve adding targeted ingredients like compost, worm castings, or peat moss to enhance specific properties, such as organic content or water retention. By fine-tuning the soil mix with these minor changes, you can ensure that each plant in your garden receives exactly what it needs to thrive.

High Nutrient-Demanding Plants

These plants thrive in the full nutrient-rich blend of SuperSoil and require minimal adjustments for peak performance.

Cannabis

Adjustment: No adjustments needed. Cannabis plants thrive in the complete SuperSoil blend, from seedling to flowering, benefiting from its nutrient-dense, well-aerated mix that promotes strong growth and high yields.

Fruiting Vegetables (Tomatoes, Peppers, Cucumbers)

Adjustment: SuperSoil is ideal for high-demand vegetables. It provides steady nutrients, excellent moisture retention, and aeration. No adjustment needed, though peppers may benefit from a slight dilution (10-20% coco coir) for lighter feeding.

Flowering Plants (Roses, Dahlias, Zinnias)

Adjustment: No adjustment Needed. For heavy-feeding flowers like roses and dahlias, use SuperSoil as-is. The rich nutrient profile supports vigorous blooming. For lighter feeders like zinnias, cut with 20% peat moss or coco coir to prevent nutrient overload.

Moderate Nutrient-Demanding Plants

These plants benefit from SuperSoil’s nutrients but may require minor adjustments for optimal growth.

Shrubs and Bushes (Hydrangeas, Azaleas, Boxwood)

Adjustment: For large, nutrient-hungry shrubs like hydrangeas, SuperSoil can be used as-is. For smaller shrubs like azaleas, cut with 20-30% plain garden soil to avoid over-nutrition.

Perennials (Hostas, Daylilies, Coneflowers)

Adjustment: SuperSoil works well for heavy-feeding perennials, but for lighter feeders like daylilies, mix in 20% garden soil to maintain a balance between nutrients and structure.

Berries (Strawberries, Blueberries, Raspberries)

Adjustment: SuperSoil provides excellent support for most berries. For blueberries, which prefer more acidic soils, add 10-20% peat moss to increase acidity. For strawberries and raspberries, cut SuperSoil with 10-20% perlite for enhanced drainage.

Fruit Trees (Citrus, Apples, Figs)

Adjustment: Use SuperSoil for young trees to support early growth. For established, mature trees, cut with 20% sandy loam or garden soil to reduce the nutrient intensity and avoid overwhelming the tree roots.

Less Nutrient-Demanding Plants

These plants prefer soils with moderate nutrients. SuperSoil can be used as a conditioner, cut with other soil mediums, or diluted to prevent overfeeding.

Leafy Greens (Lettuce, Spinach, Kale)

Adjustment: Cut SuperSoil with 20-30% coco coir or plain garden soil. This reduces the nutrient intensity, providing a balanced environment for leafy greens to thrive without becoming leggy or nutrient-burned.

Root Vegetables (Carrots, Beets, Radishes)

Adjustment: Mix SuperSoil with 20-40% sandy loam or perlite. This provides loose, well-draining soil that prevents nutrient overload and root distortion while still providing enough organic material for steady growth.

Herbs (Basil, Thyme, Oregano, Parsley)

Adjustment: Herbs need well-draining soil with moderate nutrients. Cut SuperSoil by 30-50% with coco coir or garden soil to prevent nutrient overload, especially for Mediterranean herbs like thyme and oregano.

Ornamental Grasses (Fescue, Pampas Grass, Feather Grass)

Adjustment: Mix SuperSoil with 40-50% sand or perlite. Ornamental grasses prefer nutrient-poor, well-draining soils, so a lighter mix will better mimic their native conditions.

Using SuperSoil as a Conditioner:

For less nutrient-demanding plants or when preparing a new bed, SuperSoil can be used as a conditioner to boost existing soil. Mix 10-20% SuperSoil with garden soil or sandy loam to enhance organic content, improve soil structure, and provide long-lasting nutrients without overwhelming plants. This method is especially useful for established gardens or plants that prefer moderate nutrients
