Crop Circle Gardens
Big Garden Production From Small Garden Spaces
Crop Circle Gardens ® are small round gardens that deliver big garden production from small garden spaces. They turn tiny backyards, side yards, patios, and even garden containers into highly efficient small-space vegetable gardens. Whether you’re growing on a suburban lot, an urban courtyard, or a community garden plot, a Crop Circle Garden gives you a compact, high-yield, water-smart bed.
You can use a single garden to test the system or spread several Crop Circle Gardens across your yard to take advantage of every pocket of sun and shade. A sunny spot is ideal for tomatoes and peppers, while a partially shaded corner can grow leafy greens, herbs, and chard. Simple to use and easy to set up, Crop Circle Gardens are a true “plant-and-forget” gardening system—no need to weed, and irrigation is automated, so you get consistent growth without daily hand watering.
Because each garden has a defined circular footprint, it’s easy to plan a small round garden layout for beans, chard, collards, herbs, flowers, and compact tomato plants. You get the benefits of raised beds, drip irrigation, and weed-free production in one tidy package—just set it, plant it, and watch it produce.
Each Crop Circle Garden kit is designed as a complete small-space raised garden system. You can install it directly on prepared soil or on top of a filled container, making it ideal for renters, balcony gardeners, senior gardeners, and anyone who wants a high-yield garden with low maintenance.
With these components, you can create three independent small round gardens or connect them into a mini micro-farm system. The modular design also makes it easy to expand over time as your production goals and garden confidence grow.
The first step is designing your small round garden layout by deciding where to place each Crop Circle Garden. Sun exposure and available space will determine what you can grow: tomatoes and peppers prefer full sun, while lettuce, chard, and some herbs thrive in partial shade. A roughly 10 x 10-foot area is ideal for vining crops like indeterminate tomatoes, squash, melons, and cucumbers. A 5 x 5-foot area is usually enough for most other vegetables, flowers, and herbs.
Once you’ve chosen one or more locations, lightly till and level the ground or rake a prepared bed smooth. At the center of each area, dig a hole about 30 inches wide and 30 inches deep. Fill this cavity with a nutrient-rich mix of organic fertilizer, aged compost, and loosened soil. This creates a subterranean garden bed that will feed your plants for years and encourages roots to grow deep rather than circling near the surface.
Fill the hole until the mix mounds 4 inches above grade so rainwater and irrigation can drain away from the Crop Circle Garden, not pool at the base. Then lay the ground cover over the area, centering the pre-cut opening over your filled planting zone. Use the included staples to secure the ground cover tightly to the soil, preventing uplift from wind and creating a clean, mud-free, weed-suppressing surface.
Insert the Crop Circle Garden into the ground cover opening and secure it with the three galvanized spike fasteners. Transplant seedlings or sow seeds in the exposed center opening. Attach a garden hose or ¼" drip line to the garden’s inlet. A hose-end timer at your spigot or tap automates watering so your small round gardens receive steady, consistent moisture with minimal effort.
Over time, you can rotate crops within each circle—beans one season, peppers or tomatoes the next—to mimic crop rotation in a traditional garden while still working in a compact footprint.
With many crops, harvesting occurs continuously throughout the season. Leafy greens, beans, herbs, and some peppers can be picked multiple times, turning a single Crop Circle Garden into a steady source of fresh produce. For crops with a more defined harvest window, like certain tomatoes or squash, Crop Circle Gardens can often be replanted to grow a second or even third crop, especially in long-season climates.
To replant a Crop Circle Garden, cut the plant down, leaving about 4 inches of stem as a handle. Disconnect the hose, remove the spike fasteners, and lift off the garden unit to expose the circular planting zone under the ground cover. Pull out the old root system, then use a hand spade to dig an 8-inch deep hole within the soil circle. Cavitate or flare the bottom of the hole to create a gently tapered bowl, which allows more nutrient-rich fill and room for roots to expand.
Refill the hole with a fresh mix of aged compost and organic fertilizer tailored to your next crop. For example, you might add Epsom salt for tomatoes and peppers, or extra phosphorus for root crops. Reinstall the Crop Circle Garden, secure it with spikes, reconnect the hose, and sow seeds or transplant new seedlings. In just a few minutes, you’ve effectively “recharged” your small round garden for another high-yield cycle.
These small round gardens are exceptionally productive, particularly for multi-bearing plants like beans, peppers, eggplant, cucumbers, tomatoes, and cut flowers. Because roots grow into a deep, nutrient-rich core and water is delivered efficiently, plants experience less stress and more steady growth than in typical pots or shallow beds.
The examples below show the production potential from a single Crop Circle Garden. When you multiply those yields across three gardens—or an entire backyard of small round gardens—you get a surprisingly large harvest from a minimal footprint. For more detailed planning, you can also use the Garden Yield Calculator to estimate total pounds of produce per season.
Garden beans are one of the most rewarding crops for a Crop Circle Garden. Bush beans are preferred for small round gardens because the plants are compact and self-supporting—no trellis required. You can plant yellow, purple, and green snap beans, as well as light and dark kidney beans, bush lima beans, and navy beans for soups and winter storage.
Green snap beans are generally more prolific than colored beans, often out-producing by a 2-to-1 margin. A variety such as Contender green bean can produce 70–80 pods per plant under good conditions. A grouping of 10 bush bean plants in one Crop Circle Garden can yield 700–800 pods—or roughly 10 pounds of tender, stringless beans. With succession planting, a single small round garden can provide a continuous harvest of beans for fresh eating, freezing, or canning.
Chard has quickly become a favorite vegetable in modern kitchen gardens and small-space raised beds. New varieties offer both beauty and flavor, making them ideal for edible landscaping and round garden designs. Fordhook Giant, a classic heirloom Swiss chard, can grow over 2 feet tall in a Crop Circle Garden, producing large, tender leaves for sautés, soups, and smoothies.
Colorful varieties like Bright Lights, Rainbow, and Canary Yellow add ornamental interest with their vivid stems and veins. In terms of weight, not all chard leaves are equal—Fordhook leaves are especially hefty, weighing about half a pound each when harvested young. A first harvest of 15 leaves is typical, and because chard re-grows after cutting, you can enjoy up to three cuttings per season. That’s about 45 leaves or more than 22 pounds of chard from a single small round garden.
Collards are a staple in many Southern and Southwestern gardens and do exceptionally well in small round gardens and garden containers. There are two main types: heading and loose leaf. Loose-leaf varieties like Georgia Southern and Vates are excellent for containers and Crop Circle Gardens, while Champion and Morris Heading are often chosen for in-ground garden beds.
A Crop Circle Garden growing collards—especially in a garden container—can produce a generous, repeat harvest. A single plant can yield a dozen large leaves that weigh around a pound each. Much like chard, collards re-sprout after cutting; with 2–3 cuttings in a season, one small round garden can produce 30–36 leaves or roughly 17–18 pounds of nutrient-dense greens.
There are two broad categories of peppers to grow in the garden: sweet peppers and hot chile peppers. Bell peppers are the most popular sweet pepper variety, followed by banana peppers and Italian frying peppers. A Crop Circle Garden is perfectly sized for 2–3 pepper plants, giving them enough root depth and canopy space to thrive.
In a well-managed garden, two bell pepper plants can produce around 60 colored bells in a season. Hot peppers—jalapeños, serranos, cayennes, and others—are even more prolific, often yielding 100 or more peppers from two plants. For more detailed pepper advice, you can visit Growing Peppers to dial in spacing, pruning, and irrigation for maximum yield and flavor.
Chives are a perfect herb for small round gardens and containers because they have a small root system and produce abundant top growth. There are two main types: common chives and garlic chives. Both varieties can be grown in Crop Circle Gardens for constant harvests of fresh snips for potatoes, eggs, soups, and salads.
A small 2-inch clump of rooted chives from a nursery will quickly expand to fill the 7-inch diameter of the Crop Circle Garden planting zone, producing more than 100 shoots and sprigs. With regular cutting, chives remain tender and productive, providing a steady supply of fresh herbs from a very small garden footprint.
Basil thrives in containers and grows even better in a container equipped with a Crop Circle Garden. Because basil has shallow roots and responds well to frequent trimming, it’s one of the best herbs for a small-space herb garden. The most popular varieties for gardens and containers include Genovese Italian basil, Thai basil, lemon basil, purple basil, and lime basil.
Continuous trimming of basil plants keeps them bushy and prevents early flowering and seed set, which can make leaves bitter. In a Crop Circle Garden, you can grow 3–5 basil plants, depending on the variety and your climate. Over the course of the season, those plants can yield a pound or more of fragrant basil leaves for pesto, salads, sauces, and drying.
Crop Circle Gardens aren’t just for vegetables and herbs—they also make excellent small round flower beds. The best flowers for containers and small circular gardens include Begonia, Nasturtium, Verbena, Angelonia, Million Bells, Coleus, Pansies, and Black-eyed Susan. In garden beds around the circle you can add Marigolds, Lavender, Borage, Sunflowers, Zinnias, Daisies, Lilies, Tulips, Roses, Daffodils, Petunias, and Peonies.
Some flowers, like Zinnias and certain Marigolds, reward continuous picking with more blooms, making them ideal for cut-flower production. Others, such as Tulips, produce a single flush. A single Crop Circle Garden can easily produce around 60 usable blooms over the course of a season, especially if you choose cut-and-come-again varieties.
Tomatoes are the star of many small-space gardens. There are four main types commonly grown in gardens and containers: beefsteak (the classic hamburger tomato), cherry (the most popular snacking tomato), globe (salad tomatoes), and paste (sauce and canning tomatoes). Each type can be further divided into determinate (bushy, non-vining plants) and indeterminate (vining plants), which typically require trellising and support.
A single Crop Circle Garden can grow up to three tomato plants, depending on variety and climate. Under good management, one small round garden can yield approximately 50 beefsteak tomatoes, 200 paste tomatoes, 400 globe tomatoes, or 1,000+ cherry tomatoes. For more detail on spacing, pruning, and irrigation, see the full Crop Circle Garden Yield Calculator and the dedicated growing tomatoes guide .
Tomatoes are one of the most popular container crops, but traditional pots and vertical cages often limit root development and overall yield. Growing tomatoes in a container equipped with a Crop Circle Garden removes many of the typical constraints of container gardening. The circular planting zone prevents root-binding and allows deeper rooting, while the integrated irrigation delivers consistent moisture right where roots need it.
When paired with a Tomato Volcano or similar vertical support, tomatoes can grow with their natural vining habit rather than being cramped into a narrow cage. This combination dramatically increases flowering and fruit set. In a properly managed system, 50 or more beefsteaks and over 1,000 cherry tomatoes can be harvested from one tomato plant in a garden container equipped with a Crop Circle Garden and Root Tube-style deep rooting system.

A Crop Circle Garden is a spiral or tri-spiral garden layout that concentrates irrigation, soil fertility, and human access around a central hub. Curved raised rings and radial beds shorten walking distance, simplify watering, and improve harvest efficiency compared to long, straight rows. The result is a high-yield, water-smart garden that fits into small backyards, schoolyards, and community spaces. Crop Circle systems represent an advanced implementation of crop smart irrigation principles.
When combined with zoned drip irrigation, deep mulch, and living soil practices, many Crop Circle Garden installations target up to 90% less water and around 85% less fertilizer than conventionally watered beds. Because water and nutrients are delivered directly to the root zone on a schedule, plants stay productive with far fewer inputs.
Typical Crop Circle Garden diameters range from 12 to 40 feet. A complete system can include:
These modules scale from small backyard gardens to school and neighborhood community gardens.
Yes. Crop Circle Gardens can be designed with ADA-friendly paths, ergonomic raised-bed heights, and short reach distances from the spiral walkway. This makes planting, weeding, and harvesting easier for children, seniors, and people with limited mobility, while still maximizing planting area.
Almost any crop can be grown in a spiral, but layout matters. Place fast-growing greens and herbs near the center for frequent harvests, while taller crops such as tomatoes, peppers, okra, and sunflowers belong toward the outer ring. Group plants by height, water needs, and days-to-maturity to simplify irrigation scheduling and crop rotation.
A central manifold feeds multiple radial or spiral zones using pressure-compensating drip lines. Filters, pressure regulators, and an automatic timer keep the system consistent and low-maintenance. Heavy organic mulch is added over drip lines to reduce evaporation, protect emitters, and support healthy soil biology.
Yes. On difficult sites, installers often combine raised rings with imported soil and compost, broadfork or subsoil the planting area, and add biochar and microbial inoculants. Starting with cover crops or green manures can quickly rebuild soil structure and life under and around the spiral beds.
Crop Circle Gardens support regenerative gardening practices. Key strategies include:
Together these practices reduce pest pressure and fungal disease while building long-term soil fertility.
Ongoing maintenance is focused on succession planting, irrigation checks, and soil care:
