If you have a raised bed, it does not mean that the filling method is the same. Especially when you are using metal raised garden beds, what you really need to consider is not “which filling method sounds more eco-friendly," but how deep your raised bed is, what materials you have at hand, and how you want the soil to change in the next few growing seasons.
Both lasagna gardening and hugelkultur can use organic materials such as garden waste, fallen leaves, and compost, but the two solve the problem in different ways. Lasagna gardening emphasizes the gradual decomposition of organic matter and the improvement of the planting environment through the stratification of different materials. Hugelkultur uses wood as an important structure at the bottom, allowing the larger woody materials to gradually release nutrients during decomposition while helping the bed retain moisture. What you end up with is not a raised bed that simply “fills in the materials," but a soil system that will continue to change over time.
Therefore, if you are preparing a new metal raised bed, instead of deciding how much soil to buy, it is better to decide which filling method is more suitable for your planting goals. Next, we'll provide an in-depth comparison of the two to help you make an informed choice.
What Are Hugelkultur Gardening and Lasagna Gardening?
However, before choosing fertilizer, you still need to distinguish between organic fertilizer and compost.
What Is a Hugelkultur Filling Method?
Hugelkultur filling is primarily an orderly accumulation of organic material such as wood, twigs, dead leaves, etc. into the garden beds. As this organic material gradually decomposes, it releases large amounts of nutrients and provides excellent water retention. As the wood and organic materials degrade, the Hugelkultur garden beds develop a natural soil structure that improves soil health year after year.
The hugelkultur filling method relies more on the internal space of the raised bed. The wood materials need to occupy a certain height of the bed, and the deeper the wood, the more it can make full use of the advantages of this filling method. But this does not mean that Hugelkultur is just “putting a few pieces of wood under it.” The type, size, state of the wood, and the combination of the upper organic materials will affect the subsequent decomposition process. Hugelkultur requires more material preparation and handling in the early stage, but in exchange, the advantage is a planting environment that can continue to change as the woody materials gradually decompose.
What Is a Lasagna Filling Method?
Lasagna garden bed filling method is a way to build rich soil by layering and stacking organic materials. These materials include cardboard, compost, grass, leaves, and grass clippings, which provide essential nutrients to plants while suppressing weed growth during decomposition. The key feature is that there is no need to turn the soil, reducing the risk of soil compaction.
Lasagna filling method is easy to collect the materials. If you are cleaning up fallen leaves, mowing the lawn, or already have cardboard, compost, and other gardening waste at hand, Lasagna gardening can directly convert these materials into part of the raised bed instead of treating them as waste.
At the same time, it is also more suitable for gardeners who want to establish a planting environment faster. Since brown materials and green materials decompose simultaneously, new organic matter can continuously enter the soil. However, this rapid change also means that the material in the raised bed will gradually settle, so it is still necessary to supplement compost or soil according to the actual height and soil condition in the future.
In conclusion, Lasagna gardening focuses on "layering," while Hugelkultur focuses on a “wooden core." The former makes it easier to use the organic materials available daily, while the latter makes fuller use of the space and water storage provided by logs and branches. After understanding this basic difference, the next step is to take a closer look at how the two raised beds should be established and where the different materials should be placed.
How to Build a Hugelkultur and Lasagna Raised Garden Bed
Once you determine the filling method, the most important thing next is not to stuff as many materials into the raised bed as possible but to establish different levels in a reasonable order. Although the two methods rely on the decomposition of organic materials, the focus of construction is different. Hugelkultur needs to establish a bottom core formed by wooden materials at first, while Lasagna gardening needs to form the main body through the alternating stacking of brown materials and green materials.
How to Build a Hugelkultur Raised Bed
Step 1: Prepare the Bottom Layer. First, put the larger logs at the bottom of the metal raised bed and try to make them fit each other. The larger wood should be located at the bottom, and the smaller branches should be placed on top, which can reduce excessive internal voids and form a stable wooden core at the same time. When choosing wood, priority should be given to the use of untreated wood without obvious diseases or pests. If the source of wood is not clear, especially if there is a possibility of wood pest activity such as termites, it is not suitable for direct placement in the raised bed. For areas that are vulnerable to underground pests such as gophers, a suitable gopher wire can also be installed as additional physical protection before filling.
Step 2: Fill the Gaps With Smaller Organic Materials. After the large pieces of wood are put away, smaller organic materials such as branches, leaves, straw, etc. are used to fill the gaps. This is not done simply to increase the amount of filling but to gradually form a continuous organic layer of materials of different sizes. At this stage, a certain proportion of nitrogen-rich materials, such as grass clippings or other green garden materials suitable for composting, can also be added. They can participate in the subsequent decomposition process, forming a more complete decomposition system between wood and other organic matter.
Step 3: Add Compost and Planting Soil. When the wooden materials and other organic materials reach the appropriate height, add compost to the top and cover with a layer of high-quality garden soil. The area that is really used for the growth of plant roots is mainly located in the upper part, so this layer cannot simply be replaced by a large amount of undissolved wood or thick materials.
After completion, the topsoil can be slightly leveled, or a slight slope can be formed, and then fully watered to allow the different materials to begin to settle and decompose. Hugelkultur garden beds require regular watering in the early stages of establishment, while as the internal materials gradually stabilize, the water storage effect of the wooden core will become more obvious.
For Hugelkultur, the height of the raised bed is particularly important. If the bed is too shallow, large pieces of wood will occupy too much planting space and will not be able to fully utilize the structural advantages of this filling method. Therefore, compared with shallow raised beds, deeper beds are more suitable for this method. A 17-inch raised bed is a more suitable choice, while a 32-inch raised bed can provide more space for the root system and the internal filling structure.
How to Build a Lasagna Garden Bed
Step 1: Create the Base Layer. In the assembled raised bed, lay a few layers of cardboard or thick newspaper at the bottom and let the edges overlap each other. This bottom layer is mainly used to cover the original grass and weeds and will gradually decompose over time and become part of organic matter. After laying it out, wet it thoroughly to make the material fit the ground and provide the necessary moisture for subsequent decomposition.
Step 2: Build the Brown and Green Layers. Next, brown materials and green materials will be added alternately. Brown materials include dried leaves, straw, shredded paper, wood chips, etc.; green materials include grass clippings, vegetable scraps, coffee grounds, or fresh garden waste. The former mainly provides carbonaceous materials and structures, while the latter provides a richer source of nitrogen. The combination of the two can support the continuous decomposition of organic matter. There is no need to pursue a fixed number of layers. It is more important to avoid the formation of a single layer of a certain material that is too thick and to keep the entire filling process with sufficient moisture and air space.
Step 3: Finish With Compost and Soil. When the brown and green materials are stacked to the right height, add compost to the top and cover with a layer of garden soil suitable for plant growth. In this way, the upper soil can be directly used as the main growth area of the plant root system, while the organic materials below continue to decompose.
After the filling is completed, water is poured through again to make the entire bed fully settle. If you are ready to plant right away, you need to pay attention to the thickness of the topsoil to ensure that the seedlings or plant roots will not directly contact organic materials that have not yet been decomposed.
Lasagna Garden Bed vs. Hugelkultur: Which One Is Better?
It is difficult to judge which is better between a Lasagna Garden Bed and a Hugelkultur Garden Bed, because the advantages of the two methods aren't the same. What is really worth comparing is how the two methods affect the filling structure, material decomposition, moisture retention, and soil improvement after being placed in the metal raised bed. These differences will ultimately determine which method is more suitable for your planting method.
Materials and Structure
First of all, there is a clear difference between the two methods in the composition of the material. Lasagna gardening has relatively flexible material requirements, mainly relying on materials such as cardboard, dried leaves, straw, grass clippings, vegetable scraps, and compost to fill raised beds through the combination of different layers. Its greatest convenience is that many of these materials can directly come from daily gardening activities, such as grass clippings from lawn mowing, leaves collected in autumn, or some compostable organic waste produced in the home.
Hugelkultur needs to solve a more critical question first: whether it is possible to obtain suitable wood. Logs and branches form the bottom core, and other organic materials are refilled around and above the wooden structure. Therefore, it not only requires larger materials, but also needs to consider the source, state, and size of the wood in advance. For raised beds, this structure is especially suitable for deeper beds, because the wooden core itself needs to occupy a certain amount of space.
Decomposition Speed
Different materials mean that the decomposition speed is different. The materials in the Lasagna bed are mainly organic matter that is easy to decompose, so the layers will gradually shrink over time and be converted into organic matter in the soil. Such changes can quickly improve the organic matter condition in the planting bed, but it also means that the height of the bed may decrease as the material decomposes, and compost or soil needs to be supplemented according to the actual situation.
Hugelkultur garden beds decompose more slowly. Larger logs and branches are located at the bottom, and their decomposition process is usually slower than that of fine plant materials, so they will not change the entire filling structure as quickly as Lasagna bed. Meanwhile, wood will continue to participate in the organic matter cycle in the process of gradual decomposition, making Hugelkultur gardening more inclined toward long-term changes in filling methods.
Water Retention
The filling material in Lasagna bed can improve the soil structure and help the raised bed maintain a certain humidity. However, as these materials continue to decompose, the original level will gradually change. Therefore, normal watering is still required according to the weather, plant needs, and soil condition.
Hugelkultur's advantage comes from the wooden material at the bottom. Logs and branches form a larger organic structure inside the bed and can absorb and store part of the water. For gardeners who need a more stable water supply or want to reduce frequent irrigation, Hugelkultur is usually more worthy of consideration. However, this does not mean that Hugelkultur will not need watering at all after it is built. The new bed still needs to be fully watered to establish a good humidity environment for wood, organic materials, and soil. After that, it also needs to be managed according to the actual planting conditions.
Soil Improvement
From the perspective of soil improvement, both methods can increase organic matter, but the path of formation is different. Lasagna gardening is adding a large number of organic materials from different sources to a raised bed in a short period of time. Brown materials and green materials are continuously transformed during decomposition, and with compost and soil, they form an environment suitable for plant growth. Therefore, it is suitable for situations where the original soil quality is poor or the soil structure is improved through organic materials.
Hugelkultur gardening is more time-dependent. The wood at the bottom will not be decomposed immediately but gradually transformed in a longer process while participating in the organic matter cycle with other organic fillers. In other words, its advantage is not just to “fill the raised bed," but to keep an organic core inside the bed that can change for a long time.
So, which one should you choose? If you value the easy availability of materials, the relative simplicity of construction, and the faster improvement of the organic matter environment of the raised bed, the Lasagna filling method will be a more direct choice. Especially when using a shallower raised bed, there is no need to look for a large number of logs and branches to fill the bed. If your raised bed is deep and you can get enough untreated logs and branches without obvious pests and diseases, then Hugelkultur is more worth considering.
FAQs
1. Can You Combine Lasagna Gardening and Hugelkultur?
Yes, you can. The two methods are not completely mutually exclusive. In fact, they can be combined according to the depth of the raised bed and the material at hand. The more common way is to place logs and branches at the bottom, use Hugelkultur's wooden core to build a deeper foundation, and then continue to add leaves, straw, grass clippings, compost, and other organic materials at the top alternatively, and finally cover with garden soil.
2. Which Raised Bed Height Is Best for Hugelkultur or Lasagna Gardening?
A raised bed depth does not restrict Lasagna gardening because it mainly establishes the planting environment through the layering of different organic materials, so a shallower 11" tall raised bed can also use this method. However, Hugelkultur gardening should use at least a 17" tall metal raised bed. If the bed is too shallow, large pieces of wood will take up space that could have been used for plant roots, and it is not easy to give full play to the role of the wooden core.
3. Does a Hugelkultur or Lasagna Garden Bed Need to Be Refilled?
It needs. The organic materials in both filling methods will gradually decompose over time, so the height of the bed may decrease to varying degrees. This is not a disadvantage of these two methods, but the normal process of change in the organic filling method. As long as the soil level, plant root space, and overall humidity are regularly observed, the planting conditions of the raised bed can be maintained by supplementing compost or soil.
Conclusion
Both Lasagna gardening and Hugelkultur gardening can help you make better use of organic materials while improving the planting environment of a raised bed. Lasagna gardening is more suitable for using existing organic materials to establish a planting environment, while Hugelkultur is more suitable for using wooden materials to establish a deep structure with long-term changes. No matter which method is chosen, the key is not to fill the raised bed at once but to allow organic materials to continuously improve the planting environment during the subsequent decomposition process.
