Crop Circle Raised Gardens are engineered to produce large quantities of root vegetables in compact spaces. Utilizing an off-site growing medium, these gardens can thrive almost anywhere, including community gardens, parking lots, empty urban lots, and even rooftops.
Crop Circle Raised Gardens® are modular rings that form a 15-foot elevated soil-filled circle, ideal for high-density root crop planting. These gardens are quick to assemble, requiring only 30 minutes for setup. Once assembled, the cavity is filled with a nutrient-rich mix of aged animal and plant compost. A movable stretch ramp provides convenient access for seeding and weeding, ensuring ease of use.
Soil Control – Consistent, loose, loamy soil is crucial for growing well-formed root crops, ensuring proper drainage and optimal root development.
Nutrient Control – The inclusion of thoroughly mixed aged plant and animal compost guarantees the nutrient balance needed for robust crop growth.
Water Control – Intermittent irrigation is achieved using a 360-degree butterfly spray nozzle mounted at the circle’s center, conserving water—a critical feature for regions facing water scarcity.
Grow Anywhere – The system’s adaptability allows root crops to be cultivated wherever people live and work, making it an invaluable point-of-use solution.
Plant and Forget – Once operational, Crop Circle Raised Gardens require minimal attention, enabling plants to grow unmonitored until harvest.
Weed Control – High-density planting effectively suppresses weed growth within weeks, creating a low-maintenance, weed-free growing environment.
Seeds are distributed using the proprietary Crop Circle Seed Dispenser, ensuring proper spacing and eliminating the need for thinning. A half-inch layer of compost covers the seeds, which are then watered via the Crop Circle Spray Nozzle mounted on a central vertical riser. The system is connected to an external water source through a horizontal pipe, simplifying irrigation setup.
At harvest time, plants are easily removed by hand in bunches after disassembling the garden panels. This design simplifies harvesting while maintaining the integrity of the crops.
Traditional potato farming involves hilling or trenching, where soil is mounded or buried along the stem to encourage tuber formation. Optimal stem depth for potato growth is 12-16 inches, depending on soil type, and adequate spacing (typically 3 feet) ensures access for tilling and harvesting. Commercially, potatoes are watered using overhead irrigation and harvested manually or with a potato plow.
Two types of potatoes thrive in Crop Circle Raised Gardens: Sweet potatoes and root potatoes. These gardens simplify planting, maximize yields, and provide an efficient, space-saving alternative for growing these staple crops.
Crop Circle Raised Garden panels are installed on a flat, prepared soil surface. In some cases, a ground cover is added to suppress weed growth around the raised garden. Once assembled, the 20-panel circle creates a cavity that is filled with a loose, granular loam enriched with aged plant and animal compost. This nutrient-rich growth medium provides the ideal environment for root potato cultivation. To achieve optimal results, specific fertilizers are layered strategically to ensure the production of large quantities of perfectly shaped potatoes.
If using a ground cover, cut a circle six inches inside the perimeter of the garden panels to allow seed potatoes to root into the soil below. Place approximately 200 seed potatoes evenly across the soil within this circle, then cover them with three distinct layers of growth medium enriched with potato-specific fertilizers. The bottom layer should be rich in potassium to enhance storage life, the middle layer should contain phosphorus to increase tuber production, and the top layer should be high in nitrogen to support early plant growth. Fill the cavity up to an inch below the garden’s edge for best results.
Within about 10 days, approximately 500 potato plants will emerge from the soil. As the plants grow and flower, tubers develop along the buried stems, producing an estimated 5,000 potatoes. Early harvesting yields tender new potatoes, while leaving them in the soil longer allows them to mature with a thicker skin, ideal for long-term storage.
Sweet potatoes are typically grown on a flat, level surface covered with ground cover to suppress weeds before panel assembly. Unlike root potatoes, cutting a circle in the ground cover is unnecessary since sweet potatoes form just beneath the soil surface. Begin by filling the cavity one-third of the way with loose soil, then add a nutrient-rich growth medium containing phosphorus, potassium, and nitrogen to fill the remaining two-thirds, stopping an inch below the top edge. Transplant around 200 sweet potato slips, spaced a foot apart, onto the surface of the growth medium.
A 360-degree Crop Circle Spray Nozzle mounted on a central vertical riser ensures even watering of the sweet potato plants. The delicate slips should be hardened off outdoors in natural sunlight before transplanting to ensure successful growth. Within a few weeks, the plants will begin vining across the growth medium and over the sides of the raised garden. Expect a harvest of approximately 3,000 good-sized sweet potatoes after four months.
To enhance sweetness, sweet potatoes must be cured after harvest. Place them in a warm environment (65–85°F) for about a week, followed by eight weeks in a cooler area (45–65°F). Properly cured sweet potatoes can then be stored in a root cellar for several months.
Crop Circle Raised Garden panels are installed on a flat, level soil surface that is covered with a ground cover to suppress weeds. Once assembled, the 20-panel structure creates a cavity, which is then filled with a specially prepared growth medium. The optimal growth medium for growing carrots is loose sandy loam enriched with a nutrient-rich blend of aged plant and animal compost. The soil pH should be maintained between 5.8 and 6.5 to ensure the proper growth of well-formed carrots. Achieving the correct soil mix is essential, as compacted or imbalanced soil can result in constrained, crooked, or forked roots.
Before adding the growth medium, the irrigator system is installed. This system includes a vertical riser connected to a horizontal pipe that attaches to an external water source, such as a garden hose. At the top of the riser, a 360-degree Crop Circle Spray Nozzle evenly irrigates the carrots, ensuring consistent moisture throughout the growing process. This setup promotes optimal growth conditions for healthy, high-yield carrot crops.
An elevated stretch plank serves as a convenient gangway for broadcasting carrot seeds across the growth medium. Using a Crop Circle Seed Dispenser ensures precise spacing of carrot seeds, eliminating the need for thinning. The plank is also utilized to remove the few weeds that may sprout before the carrot tops grow dense enough to suppress them naturally. After broadcasting, the seeds are covered with a thin, half-inch layer of growth medium to protect them and promote healthy germination.
When it’s time to harvest, the carrots are easily pulled in bunches by hand after disassembling the panels. In most growing zones, it is possible to achieve a second harvest of carrots within the same season. A Crop Circle Raised Garden can produce between 5,000 and 8,000 carrots every three months, making it an incredibly efficient growing system.
At the end of the growing season, the Crop Circle Raised Garden is carefully disassembled, cleaned, and stored in a dry location. Proper storage during the winter months ensures the components remain in excellent condition, lasting up to 30 years with proper care. The ground cover can stay in place for over a decade before requiring replacement, while only the garden panels and irrigation system need seasonal assembly and disassembly. The growth medium can be discarded, replaced, or recharged at the start of each new season. Establishing a second growing area nearby allows for easy relocation of the 20-panel unit, simplifying soil recharging and ensuring optimal growing conditions for subsequent plantings.
