❓ Frequently Asked Questions

What plants grow best in a rock garden?

Sedums, hens and chicks (sempervivum), creeping thyme, creeping phlox, alpine dianthus, blue fescue, lavender, and ice plant thrive in the sharp drainage rock gardens provide. Match plants to your USDA zone.

How do I prepare the soil for a rock garden?

Most rock garden plants need excellent drainage. Mix native soil 50/50 with coarse sand or fine gravel. On flat ground, build a mound or berm 12–18" high. Never use straight clay soil.

How deep should gravel be in a rock garden?

Use 2–3" of gravel or crushed stone as mulch between plants and rocks. Below rocks and boulders, ensure at least 4" of compacted gravel base so they don't sink over time.

Do rock gardens need maintenance?

Very little — occasional weeding, trimming overgrown plants, and topping off gravel every few years. No mowing, no mulch replacement, no fertilizing needed for most rock garden plants.

How much do rocks cost for landscaping?

Bulk rock runs $50–$500/ton depending on type. One ton covers roughly 80–100 sq ft at 2" depth for gravel, or provides 5–8 medium boulders. Buy from landscape supply yards, not bagged from hardware stores.

Can I build a rock garden in shade?

Yes — use moss, ferns, heuchera, hostas, and native woodland plants instead of sun-loving alpines. Replace gravel mulch with leaf mulch or moss. Japanese moss-and-stone gardens are shade-perfect.
