Rock Gardens
Gritty, fast-draining mix
- Combine native soil with gravel, sand, and small stones
- Keep organic matter low
- Ideal for alpine and low-water perennials
Why it works: Prevents excess moisture while providing stability and airflow.
General Garden Beds
Well-draining garden soil enriched with organic matter
- Use native soil mixed with compost (about 30–40%)
- Soil should be loose, crumbly, and able to hold moisture without staying soggy
- Ideal for flowering perennials like coneflower, salvia, and black-eyed Susan
Why it works: Encourages deep root growth and balanced moisture retention.
Dry or Water-Wise Gardens
Sandy or gritty, fast-draining soil
- Mix native soil with sand, gravel, or decomposed granite
- Avoid heavy compost or peat moss
- Ideal for drought-tolerant perennials such as lavender, penstemon, and yarrow
Why it works: Prevents root rot and mimics natural dry-climate conditions.
Raised Beds
Lightweight, nutrient-rich soil mix
- Blend topsoil, compost, and aged bark or coconut coir
- Soil should drain easily but hold enough moisture between waterings
- Works well for most perennials, especially where native soil is poor
Why it works: Provides consistent structure, nutrients, and airflow for roots.
Containers and Pots
High-quality potting mix (never garden soil)
- Use a potting mix designed for containers
- For drought-tolerant perennials, add pumice or perlite
- Ensure pots have drainage holes
Why it works: Prevents compaction and ensures proper drainage in confined spaces.
Clay or Heavy Soils
Amended native soil
- Mix in compost, aged manure, and coarse sand
- Avoid adding only sand—always pair with organic matter
- Choose perennials that tolerate heavier soils, like day-lilies or asters
Why it works: Improves drainage, structure, and root penetration over time.
