Building Herb Spirals: A Space-Saving Gardening Trend
Love Fresh Herbs? Try an Herb Spiral!
If you love fresh herbs but don’t have a ton of space, an herb spiral might be your new best friend! This clever garden design is not only eye-catching but also incredibly practical. Whether you have a sprawling backyard or a small balcony, you can create a thriving herb garden in a compact space.
In this guide, we’ll walk you through what an herb spiral is, why it’s such a great gardening hack, and how you can build one yourself!
What is an Herb Spiral?
An herb spiral is a raised, spiral-shaped garden bed designed to maximize growing space while creating different microclimates. This means you can grow a variety of herbs—each with different sunlight and moisture needs—all in one place. The top of the spiral stays drier, perfect for Mediterranean herbs like rosemary and thyme, while the lower levels retain more moisture, making them ideal for plants like mint and parsley.
Why You’ll Love an Herb Spiral
🌿 Maximizes Space
Perfect for small gardens, patios, and urban spaces, an herb spiral lets you grow more in less space.
🌞 Creates Microclimates
Different levels mean different moisture and sunlight conditions, so you can mix and match herbs that wouldn’t normally thrive together.
👌 Easy to Maintain
No more bending or stretching—just reach in and snip fresh herbs whenever you need them!
💧 Saves Water
Water trickles down naturally, reducing waste and keeping lower plants hydrated.
🌱 Looks Stunning
An herb spiral adds beauty and structure to your garden, making it a real focal point.
How to Build Your Own Herb Spiral
1️⃣ Pick the Perfect Spot
Find a sunny location with good drainage. Most herbs love at least 6 hours of sunlight a day.
2️⃣ Gather Your Materials
Here’s what you’ll need:
- Bricks, stones, or reclaimed materials for the spiral walls
- Quality soil mix (garden soil + compost + sand for drainage)
- Mulch (optional but helps retain moisture)
- A mix of herbs suited to different conditions
3️⃣ Map Out Your Spiral
Use a rope or hose to outline your spiral on the ground. 3-6 feet in diameter and about 2-3 feet tall is a great size to start with.
4️⃣ Build It Up
Stack your bricks or stones along the spiral outline, gradually increasing height toward the center.
5️⃣ Fill with Soil
Layer in your soil mix, adding extra compost for nutrients.
6️⃣ Time to Plant!
Group your herbs by their moisture and sun needs:
- Top (Dry & Sunny): Rosemary, Thyme, Oregano, Lavender
- Middle (Moderate Moisture): Basil, Chives, Cilantro, Sage
- Bottom (Moist & Shady): Mint, Parsley, Lemon Balm
7️⃣ Water & Mulch
Give your new herb spiral a good soak and add some mulch to help retain moisture.
Best Herbs to Grow in an Herb Spiral
Not sure which herbs to plant? Here are some great choices:
- Loves the Dry Top: Rosemary, Thyme, Lavender, Oregano
- Happy in the Middle: Basil, Cilantro, Chives, Sage

Keeping Your Herb Spiral Happy
- Water Smartly: The top dries out faster, so check often.
