A Brief History of Gardens and Geometric Shapes
The idea of growing vegetables, fruits, herbs, and flowers together in aesthetically-pleasing, geometric designs is not a new invention.
Striving to blend beauty with efficient food production has been around since at least medieval Europe. Monasteries were among the first to mingle edibles with a desire for eye-catching gardens that encouraged contemplative walks.
I suspect gardens with geometric shapes—such as circles and rectangles—extend even further back in history.
Dating to at least the first century BCE, ‘Paradise Gardens’ were created in Old Persia: Impeccably designed gardens combined the production of food and medicine with beauty for wealthy families.
These Persian influences can be seen in the gardens of Moorish Spain from the early 12th century CE, which I witnessed firsthand on a trip to Spain many years ago.
Alcazar of Segovia is an example of one such formal garden.
Water features were an essential component of these early-day gardens, as was the need to border the garden with trees or shrubs to create a formal boundary and keep wildlife out.
For us modern-day types, the circle garden is an opportunity to grow edibles in a location where we might otherwise need to mind the aesthetics, such as a front or side yard. However, because circle gardens can be efficient and low-maintenance, they can even be useful where aesthetics aren’t the primary concern.

The Circle Garden Design
The circle garden design includes paths leading to the center from each of the four cardinal directions, creating four gardening quadrants. The design also often includes a focal point in the center of the circle.
By designing a garden in the shape of a circle, the gardener can access all four beds from a central vantage point, reducing labor.
Vary the dimensions of the circle, the gardening quadrants, and the paths to match a particular location and style to create a circle garden on a grand or small scale.
Ideas for the Central Focal Point of a Circle Garden
The central focal point of a circle garden can include a number of different things, depending on the size of the garden and your goals. Here are some ideas:
- A bench or bistro table could make an inviting place to sit, surrounded by gardens.
- A teepee or obelisk would make a beautiful statement on its own or it could be used to grow vining vegetables or flowers (I love scarlet runner beans or black-eyed Susan vine – Thunbergia).
- An herb garden or herb spiral
- A wildlife-themed center could include a bird house or bird bath. (Here’s more about inviting birds to your food garden.) Flowers underneath can attract beneficial insects. Some of my favorites are calendula, comfrey, oregano, sweet alyssum, and yarrow.
- Omit the central focal point in a small circle garden to make room for accessing the gardens more easily.
The Perimeter of a Circle Garden
The perimeter of a circle garden can be a number of different things, depending on your site’s conditions and your garden’s size.
- For a formal English garden, line the perimeter with boxwoods or another evergreen shrub. Keep them pruned for a short height and tidiness to let light in while forming a barrier against invading grass, kids, or dogs.
- Garden border fencing can also define the space while keeping kids and dogs out.
- Trellising would allow you to grow your climbing vegetables and flowers around the perimeter to create privacy for an outdoor room with a sitting area in the center of the garden.
- If an open view is more your style, then simply give the border a good edging to keep grass out. When I create an edging trench, I use an edger and a sharp spade shovel.

Circle Garden Examples
The following are some examples of circle gardens of different sizes.
You’ll notice in the above diagram that rather than have a central focal point, this small garden uses the inner circle as a staging area for accessing the four, 3-foot-wide garden quadrants.
This allows enough room for turning a wheelbarrow around comfortably or collecting harvest baskets.
In the above diagram, the additional space allows for a central focal point to be included, such as an herb garden, with a circular path that separates the herb garden from the four garden quadrants.
Although this garden is larger than the small circle garden, it still only allows for a 3-foot wide central path and 3-foot-wide garden quadrants.
The large circle garden allows for a central focal point—such as a bean teepee planted with edible flowers or a sitting area—to be surrounded by a sizable circular pathway that allows easy access to the four garden quadrants. It also increases the growing space of each quadrant to a 4-foot-width.
How to Make a Circle Garden
A small circle garden will take up a circular area with a diameter of at least 11 feet, a medium-sized garden will require about 17 feet diameter, and a large circle garden will require a diameter of at least 23 feet (or larger).
You will need to decide beforehand what size garden you intend to create, and whether/what kind of central focal point you want. Drawing it out can help the process go more smoothly.
Circle Garden Materials:
- Wooden stakes and/or utility flags
- rubber mallet
- measuring tape
- twine
- digging fork
- cardboard to cover area
- wheelbarrow
- shovel or pitchfork
- wood chips to cover paths (or keep the paths as grass, but be wary of having to fight to keep the grass out of the beds)
- (1-2 cubic yards) any combination of compost soil, worm castings, homemade compost, chemical-free aged manure, or aged leaf mold to cover garden bed areas
- desired plants and other optional supplies for the garden beds, central focal point, and perimeter
Tired of generic permaculture design advice that you can’t apply to your specific goals? If so, check out my Permaculture Design Program and get the tools and support needed to create and implement your own permaculture design.
1: Mark off the diameter of the area.
Use the measuring tape to mark off the general area. Use the mallet to drive a stake into the center of the area to mark it, then tie a piece of twine to the stake that is the length of the radius of your circle. (The radius is half the diameter: The radius of an 11-foot diameter is 5.5 feet).
Using the twine, rotate around the circle marking the perimeter with stakes or flags.
2: Mark the paths, beds, and central focal point, as appropriate.
Traditionally the paths will head in each of the cardinal directions.
Whether you’re creating a small garden without a central focal point or a large garden with a central herb garden, you’ll want to mark off all of the areas using the stakes or flags before breaking ground.
3: Create the pathways.
Now that everything is marked off, it should be easy to identify where your paths will be. Cut the cardboard and lay it throughout the path areas, overlapping the ends to keep grass from creeping through.
Cover the cardboard with wood chips.
Alternatively you can leave the pathways as grass, but you would be wise to create a sturdy edge using the edging tool to keep grass from creeping into the beds. I would add clover seed to the grass to make it more diverse and provide nitrogen fertilizer for the surrounding beds.
With a solid path system in place, it will be easy to wheelbarrow soil materials up to the garden beds.
4: Create the garden beds.
First, use the digging fork to poke holes in the soil, loosening and aerating. This is an important step in the no-till garden.
Next, cover the garden bed areas with cardboard, overlapping the ends as you did in your paths.
Now add your soil materials to each bed, piling it as high as 12 inches (in decent soil, a few inches is fine).
A rock border or edging trenches can help to keep the newly piled soil inside the beds. Over time the soil will settle.
5: Create the central focal point and perimeter.
If you’re creating a central herb garden and/or planting a perimeter of shrubs, now is the time to create that. Otherwise, bring in your table and chairs and give the exterior perimeter a good edging, trellises, or fence.
6: Plant the garden beds and herbs.
Water your new garden well and give it a week or two to settle before planting. Waiting until after a good rain is even better. This isn’t entirely necessary, but if you have the time to wait, your new plants may be happier.
How about planting an herbal medicine garden?
A Circle Garden Case Study
At Hillside Community Garden, the community food forest that I founded in 2011, we wanted to demonstrate unique gardening strategies that would motivate residents to create beautiful and eco-friendly gardens in their own yards.
The circle garden was one such strategy that we put into practice.
The size of our circle garden was limited by other features of the garden, but we designed our circle garden to include a central herb garden.
The challenge with our garden was its situation on a hillside. Rather than place the pathways to direct north, south, east, and west, we placed the garden beds at those cardinal directions in order to reduce soil erosion and stabilize the hillside.
The paths then directed northeast, northwest, southeast, and southwest. The slope also meant that our north and south garden beds needed to be terraced.
Here are some pictures of the project:
Case Study — What worked:
The hillside was stabilized by the north and south terraced beds, and the circular shape created an interesting dynamic that broke up the monotony of the long terraces in other parts of the garden.
Case Study — What didn’t work:
For a working community garden with lots of helpers and visitors, the narrow 2.75-foot-wide pathways inside the circle were too narrow. Trying to bring in a wheelbarrow and navigate it around the small central herb spiral was a challenge.
For a garden of this size with lots of foot traffic, we probably should have omitted the central herb garden. It sure would have made tending the beds a lot easier. However, the small, simple herb spiral was a favorite of many visitors.
Whether you create a small or large circle garden, the unique shape and feel of the garden is sure to be a place of respite, pleasing the eyes with beauty and pleasing the back with reduced maintenance.
Have you created a garden in a unique geometric shape? What was your experience?

I am in the process of planning a new medicinal herb bed just outside our front door. It will border our fenced vegetable garden to the north of the new site. Now I am thinking I will make it circular, instead of the rectangle I was planning – perfect timing for me to read your post!
Most of my vegetable garden is in traditional 3 – 4 foot rows with 2 foot paths. But I have one area that is a ‘key hole’ garden, which is slowly becoming an area for perennials including the comfrey, sage, catnip, etc. I think the shape, which is open to the south side, retains heat. I wonder how the round shape will influence microclimates, if any?
Thank you for the inspiration (again!)
Amy says
Whether you make it square or circular, keep us posted 🙂
I wonder if the circle shape would create microclimates, too. It might depend on what’s planted, and where? Similar to a keyhole, I bet planting your tall stuff in the two north quadrants would create microclimate conditions. It might be different in different locations, too. Fun experiments!
Michelle says
Well, the circle garden is thriving with perennial medicinal herbs. Unfortunately at the moment, it is overgrown with pumpkins and butternut that refuse to stay in the pumpkin patch. I’m looking forward to cleaning it up this fall and making it pretty again. Everyone should have at least one circle bed – they have such a different energy and feel to them!
Amy says
Oh, this is great feedback. I love to hear that the garden has a special energy to it and that you’re enjoying it 🙂
Tom Helmers says
While vacationing in Michigan, we went across the Mackinaw bridge to the Ojibwa memorial and learning center. It was there that we found out about the medicine wheel garden. My wife and I are in the process of creating our own medicine wheel garden similar to the photos in your article.
Amy says
I love the medicine wheel garden concept! The design is healing and meditative. I hope your project goes well!
Tom says
Wild hogs found my small beginning stage food forest. I believe the six inches of decayed leaves, worms etc. attracted them. Since i now have no trees in the way I have started laying out Mandela or circle gardens with fruit trees as the central feature in 5ft raised bed, 3ft pathways and 4ft veggie beds with a mix of annual and perennials. I have space for 7 trees 24ft centers in a hexagonal pattern giving a circle within a circle pattern.
Since I have maybe 6in topsoil I start by digging out grass & weeds 12-16in deep then adding grass and partially decayed mulch from compost pile. I have a large woodchip pile that has turned into compost which will and another 1-2in when turned under. A layer of cardboard is added the 4-6in of grass and leaves added to top things off.
Walkways will get ammended with grass and leaves then eventually dugout 6-12in with soil addes to growin areas. Woodchips will be added to define walkways and hold soil in place. Walkways will enclose the outer growing circles leaving small interesting areas for perennial flower beds for pollinators. Since the area is on a slight slope walkways will need to be leveled out prior to filling with woodchips to capture and store rainwater in the area.
I have about 3 cords of three year old firewood. I am thinking of adding 12in to tree circles to allow for drainage / water storage. These hugelkultur beds should help feed the trees, etc for many years. Once established I will add clover, comfrey, etc for extra nutrients. With over 40in (1 meter) of rainfall annually AND drought on a near annual basis, water is definitely an issue. I would much rather to store in place than watch as tens of thousands of gallons flow away.
Amy says
Your project sounds very well thought out and very exciting. I hope to hear how it goes!
Jenny says
Amy,
I’m not sure if my email is the same as the one I have used in the past to comment, so you may wonder who the heck I am. (I have 4 for different purposes. Sort of ridiculous!)
Anyway, will you be attending the Midatlantic Permaculture Convergence? If you are in OH, I know you are more midwest, but it is in WV, I think. I was hoping I might be able to meet you. ☺
Amy says
That would have been so cool–it’s pretty close to me. For a variety of “life” reasons I won’t make it this year 🙁 I’m very envious–keep me updated for next years’ event, will you?
Karen Maslowski says
Amy, check out the massive circle garden at Cherry Point Farm in Shelby, Michigan. We visited last year and I was fascinated by how they’ve arranged beds of herbs in a circle, divided by type, and arranged according to geometric shapes. It’s staggeringly beautiful, and surrounded by lavender beds.
They have a gazebo that surrounds most of the garden, which has a diameter of approximately 100′, and the various beds are separated from the paths by stones. They keep several plastic-coated keys to the identification of each of the beds so you can figure out what is planted where. It must have been quite an undertaking to build and plant in the first place, but they also maintain it. Visitors are encouraged to wander around, no admission, although there is a farm market and gift shop, plus a seasonal dining area, with indoor and outdoor seating. It’s all quite wonderful.
Amy says
Sounds wonderful!
Alissa says
This is great; thank you! I just ordered a ton of medicinal herb seeds, as my main project this year will be creating a medicinal herb garden. I’ve been searching for design ideas, and this is perfect.
Dennis N says
Wow…thank you for taking the time to post your thoughts. I am an Idaho Master Gardener that decided to take out my USELESS front lawn this year and double to triple my food production. I was having a hard time coming up with a design until I read your read you circle garden ideas. You have given me a starting point and I am very grateful! Keep posting!
Kathy Scarbrough says
This post was so informative! As a result I with help of a hired strong back named Jose have created me a 25 ft. Round circle rose garden. I love it…would have never thought to do this without this post! Thank you..
Amy says
That sounds lovely!
