Gardening can be many things: fun, rewarding, educational, and sometimes frustrating. Easy, it is not. If your soil is anything like mine, digging up plots of the earth means hitting rocks and roots. Then, more rocks followed by more rocks. Even with cultivators and rototillers, digging can still be quite daunting. Mound gardening is the perfect solution to a variety of soil quality problems. Its simplicity makes it suitable for any skill level. With little effort, you can produce abundant vegetables without the hard labor often associated with traditional gardening.
Growing in mounds (or hilling) is not a new practice. When European settlers arrived in the New World, they found Indigenous growers cultivating their land using this mound-gardening technique. For centuries many tribes had been interplanting the much-studied “Three Sisters” this way. This trio of corn, beans, and squash flourished together, sustaining their people by providing a relatively nutritious diet from this combination planting. The corn, which offers support to the beans, was planted first. As the small seedlings grew, the farmers returned to hill soil around the plants, eventually creating a mound one foot high by two feet wide. The mounds were arranged in rows about two feet apart. A couple of weeks later, the beans were planted in the same hills contributing nitrogen to the soil. Between the rows, farmers planted low-growing crops such as pumpkins or squash whose leaves shaded the ground, conserving moisture and hindering weed growth.
Mound gardening is, as it sounds, literally growing in a pile of soil. The mound creates a small-scale raised bed for cultivating plants and seeds. It’s especially good for root crops requiring loose soil and space below ground. For those with small gardens, it’s a great way to optimize space. And in areas with poorly draining soil, the mound can provide better water removal than traditional planting because excess moisture drains quickly. Amending the soil in the mound with compost will enhance its quality and aid with drainage.
Create hills in mounds or rows. Start with a layer of newspaper or cardboard to act as a weed barrier, then take several shovels of quality garden soil and form a mound. Mix in a generous amount of compost or well-rotted manure. Plant your seeds or seedlings, and water well. To hill rows, shovel four to six inches of soil in a row the length you desire. Use a hoe to smooth the row and dig a furrow. Mounds tend to dry out faster than a traditional garden bed, so frequently checking your plants is good practice. Using a natural mulch such as chopped, dried leaves or straw can help keep moisture in and keep weeding to a minimum.
A wide variety of crops can be grown in mounds. In addition to the corn, beans, and squash mentioned earlier, plant root vegetables such as potatoes, beets, turnips, radishes, and carrots, as well as cucumbers and melons
Another old-world mounding technique gaining popularity is the hugelkultur, pronounced hoo-gul-culture. Originating in Germany but practiced throughout Eastern Europe, the word means “hill culture.” This gardening method creates a raised hill from rotting logs and plant debris topped with compost and soil. This produces a rich, fertile environment into which plants or seeds can be sown. Since the mound generates nutrients and holds moisture, it’s a low-effort, effective, sustainable gardening method. These mounds usually begin five to six feet in height. Then as the wood decomposes, it settles down to about two feet after several years.
Mound gardening is easy and economical. It’s a raised bed without a bed. It’s suitable for novice and experienced growers and a great way to introduce children to growing their food. Even those with little time and little space can grow vegetables this summer.

It works as a “raised rain garden” with the mound providing a water retention function. Thus, it is a sustainable stormwater management practice as the mound slows down the water runoff and allows a place for water to infiltrate back into the ground. Hügelkultur produces food.

A mound system does not have a direct discharge to a ditch, stream, or other body of water.
What are the benefits of mounding? ›
Mounds provide microsites that are warmer, better aerated and lead to better drainage and nutrient availability (Fig. 2). Figure 2. Advantages of mounding on mesic and wet sites.
Should tomatoes be grown in mounds? ›
Tomato plants require abundant moisture for best growth, so arrange for easy watering. The area selected should be well drained since poor drainage promotes root loss. Tomatoes grown on heavy or poorly drained soils should be planted in raised beds or mounds four to six inches high.

The main purpose of a mound system is to provide sufficient treatment to the natural environment to produce an effluent equivalent to, or better than, a conventional onsite disposal system.
What is the benefit of using a mound instead of a typical septic field? ›
Mound systems are one of a number of alternative systems that have been developed to overcome site conditions that limit the use of a conventional drainfield, including soils with slow or fast permeability, shallow soils over bedrock, or a high water table.
What are the benefits of a walled garden? ›
The shelter provided by enclosing walls can raise the ambient temperature within a garden by several degrees, creating a microclimate that permits plants to be grown that would not survive in the unmodified local climate.
What vegetables need to be mounded? ›
Because of this, beets are a great choice for the mound. Potatoes are plants that enjoy nicely drained soil. Carrots are as well, considering they root deep, and sweet potatoes just go wild if the mound is correctly fertilized.
