Customizable Spiral Garden DIY
A spiral garden is a versatile and practical solution for urban and hobbyist gardeners alike to maximize space. Gravity allows water to drain freely from the top of the spiral and seep to all layers, creating microclimates. A dry zone at the top and moist area at the bottom gives you many options when choosing plants. We planted tulips at the top of our spiral as they require very little water.
The Rumblestone brick pavers allow for customization of your spiral garden. Experiment with the height of the outer wall and your spiral walls. Taller walls can create an additional shaded microclimate.
Instead of planting flowers as we did, you might consider planting an herb spiral garden. Keep in mind the zones of your spiral garden to help your plants stay their healthiest.

Step 1: Build the Outer Wall
Lay out the Rumblestone outer wall as shown in your Rumblestone booklet in your chosen location. We designed our structure with a repeating pattern of one large brick followed by two small bricks. Our 106 in. diameter wall sits low at 7 in. tall, making the project more about the flowers and less about the structure. You can customize your spiral garden however you’d like. Experiment with different heights and patterns to find the perfect spiral garden for you.
Ensure your structure is level, adding soil under the bricks and packing down as needed. You should also backfill with soil around the outside wall to add support to the structure.
Step 2: Fill the Circle and Tamp
Fill in the entire circle with soil. Then pack down the soil.
Step 3: Design the Spiral
Place small Rumblestone pavers on the inside of the flags to help support the dirt. These will also help you when pouring the dirt.
Create a spiral pattern with the flags, starting at the center of your circle and working your way out. You might need to make some adjustments to your spiral to make it even.
Step 4: Create the Spiral with Soil
Pour soil along the inside of the flags, making sure that the spiral rises up gradually as you move toward the center of the circle.
Step 5: Tamp the Soil
Tamp the soil along the spiral.
Step 6: Lay the Bricks along the Spiral
Lay the Rumblestone bricks on top of the spiral in the same pattern as your outer structure. Add soil under the bricks to level as needed. You can also use a rubber mallet to adjust and level the bricks. You will need to backfill the edges somewhat to give support.
Step 7: Plant the Flowers
Next, add more soil and plant your flowering plants.
We used dark flowers at the bottom of the spiral then gradually added lighter flowers with a bright pink centerpiece.
Spend time picking your plants as there are many different choices. You might try include alternating colors or planting a mixture of flowering and non-flowering plants.
Step 8: Add Mulch
Put your choice of mulch around the plants, adding contrast to the flowers.
Step 9: Lay the Pebbles
Finally, add river rock to the edges of the spiral to create a whimsical cascading effect. You can add different sizes and shades of river rock for different effects. The contrast adds the finishing touches for our project, making the flowers pop.
