Pale limestone rocks placed at irregular angles to create planting pockets. Filled with creeping thyme, aubrieta, alyssum, and rock cress — all self-seeding and spreading to fill gaps over time.
Cottage Rock GardenTerraced Slope Rock Garden
A sloped embankment terraced with native fieldstone walls 8–12 inches tall. Each terrace holds a different cottage plant: pinks, campion, sea thrift, and dwarf phlox. Effective erosion control that blooms April through June.

How to Build a Rock Garden
Step-by-step guide for a beginner-to-intermediate DIY rock garden. Works for slopes, flat ground, and raised beds.
Choose your style and location
South-facing slopes get the most sun (best for alpine and desert plants). Flat spots work for zen and modern gardens. North-facing shaded areas suit moss and shade-tolerant plants. Decide your style first — it determines everything else.
Prepare the base
Excavate 6–12 inches and fill with gravel and coarse sand for drainage (rock garden plants hate wet feet). Slope the bed away from structures. Install landscape fabric only if you plan a pure gravel/rock look — skip it if planting between rocks.
Set boulders first
Work with odd numbers (3, 5, 7). Bury 1/3 of each boulder for a natural, established look. Tilt flat stones slightly backward to direct water toward plant roots. Set the largest stone first as the focal anchor.
Fill with alpine soil mix
Rock garden plants need fast drainage. Mix: 50% local topsoil, 25% coarse grit or crushed granite, 25% perlite or coarse sand. Fill planting pockets between stones with this mix to a depth of 12 inches.
Plant in drifts, not dots
Plant at least 3 of each species in a drift. Small alpines can be spaced 6–8 inches apart. Sprawling plants like creeping thyme or phlox need 12–18 inches. Plant in fall or early spring for best establishment.
Add gravel mulch, not bark
Top-dress with matching gravel (1/2 inch crushed granite or pea gravel). This regulates temperature, prevents crown rot, conserves moisture, and creates the natural look. Avoid organic mulch — it retains too much moisture for most rock garden plants.
Rock Types: Which to Use
Use one rock type per garden for a natural look. Match the rock to your design style.
| Rock Type | Color | Best Style | Typical Cost |
|---|---|---|---|
| Granite | Grey/pink/white | Modern, alpine, naturalistic | $180–$350/ton |
| Limestone | Tan/grey/buff | Cottage, alpine, zen | $80–$150/ton |
| Sandstone | Tan/red/orange | Desert, southwest, cottage | $100–$250/ton |
| Lava Rock | Black/red | Modern, desert, tropical | $75–$180/ton |
| River Rock | Multi-toned, smooth | Water features, naturalistic | $50–$120/ton |
| Fieldstone | Earthy tones, varied | Cottage, terracing, walls | $40–$100/ton |
| Basalt | Dark grey/black | Modern, zen, water features | $150–$300/ton |
| Quartzite | White/grey/pink | Modern, formal, statement | $200–$400/ton |
* Prices vary significantly by region and source. Local quarry rock is typically 30–50% cheaper than landscaping supply stores.
