As you flip through gardening publications and come across picture after picture of neatly arranged vegetables in a raised bed garden, you might be wondering how to replicate this setup at home. The good news is that designing and constructing a raised bed doesn’t necessitate extensive training or resources. With the right materials and a little space, you can transform a lackluster area into a stunning spot for crops!
This guide will take you through selecting the ideal materials, finding the perfect location, and building your dream raised bed.
What Is a Raised Bed (And What Can You Grow in It)?
In gardening terminology, raised beds refer to plots of land that sit above the ground level and are bordered by frames to contain the additional soil. While mounded-up beds without frames also qualify as raised beds, we’re focusing on the framed variety here. The primary motivation behind building raised beds is to enhance drainage and create an ideal environment for plants, particularly when working with less-than-ideal native soil. For instance, heavy clay can be a challenge.
Raised beds offer a solution to this problem by elevating the growing space above the problematic soil conditions. So, what can you grow in a raised bed if you decide to build one? As previously mentioned, many gardeners cultivate vegetables and fruits in these elevated plots. However, the possibilities extend far beyond those two categories. Essentially, anything that doesn’t require an excessive amount of space can thrive in a raised bed.
These contained growing spaces are particularly well-suited for plants that tend to spread or overtake areas like blackberries, bamboo, and certain types of grasses. Raised beds also provide an opportunity to create dramatically different soil conditions than those found organically. For instance, if you want to grow hydrangeas or rhododendrons but your native soil lacks the necessary acidity, a raised bed with acidic soil can be the solution.
Benefits of Having a Raised Bed
Not only do raised beds provide a more convenient and efficient way to plant your seeds, but they also offer numerous advantages for your homesteading endeavors. One of the most notable benefits is improved drainage and soil quality, which can lead to healthier plants and reduced maintenance requirements. Additionally, raised beds often require less space than traditional in-ground gardens, making them ideal for smaller plots or areas with limited sunlight.
Less Back Pain
One of the most common complaints among avid gardeners is the prevalence of back pain. This issue arises from spending extended periods in a bent-over position while tending to their plants. Prolonged exposure to this posture can have detrimental effects on overall health and wellbeing. Fortunately, raised beds offer a simple solution by elevating the growing space above ground level, thereby reducing the need for frequent bending and straining when watering or weeding.
Provide Better Drainage
In flood-prone areas, a raised bed can be a game-changer for gardeners seeking to protect their crops from waterlogged soil. By elevating the bed, excess moisture is kept at bay and drainage becomes more effective, allowing plants to thrive in a well-ventilated environment.

Helps Limit Pests
One of the most irritating challenges gardeners face is dealing with recurring pest infestations. While there are measures to deter unwanted visitors like rabbits, moles, and voles, they can still pop up unexpectedly, leaving you feeling helpless. Fortunately, raised beds offer a simple yet effective solution. By elevating your crops above ground level, you can prevent certain pests from entering the area in the first place.
Additionally, this design choice also keeps pets and livestock, such as chickens, from disrupting your plants by walking on or digging up the soil.
Reduce Weeds
While it’s not impossible for weeds to establish themselves in a raised bed, the design does provide an inherent advantage against these unwanted plants. The elevated terrain and better drainage can make it more challenging for weeds to take root, giving you a head start in maintaining a weed-free growing environment. Consistency is key, however, as regular weeding will help prevent even the most determined weeds from gaining a foothold.
Warmer Soil
One of the key benefits of raised beds is their ability to warm up more quickly in the spring and retain heat well into the fall. This means that gardeners can take advantage of an extended growing season, getting a head start on planting and harvesting crops earlier than they would with traditional soil. As a result, you’ll be able to coax your plants through the seasons, enjoying a longer period of productivity and fewer months of downtime between harvests.
Choose the Right Materials
When selecting the material for your raised bed, it’s essential to strike a balance between durability and affordability. You want the material to withstand your local climate without deteriorating over time, but you also don’t want to break the bank. The most common materials used for building raised beds are wood, metal, stone, bricks, and cement blocks, as they offer a great compromise between longevity and budget-friendliness.
Wood
When it comes to budget-friendly options, pine is the clear winner. However, if you’re looking for durability and rot-resistance, cedar, redwood, or locust might be the better choice. Wood can be used to construct the frame, walls, or even the entire structure. Consider whether chemically treated wood is suitable for your project, as it could potentially leach into the soil and impact the health of your crops.
Some builders opt for treated wood like railroad ties, but it’s ultimately a personal decision. For inspiration on creating a raised bed using scrap wood, be sure to explore our comprehensive guide.
Stone
While stones are another easily accessible resource, their unique texture and contrast can add visual appeal to your garden when paired with plants. Unlike wood, stones possess longer durability but come with heavier weight and greater difficulty in handling. Additionally, they require periodic maintenance as they tend to shift over time. If you reside in an area with a short growing period, cinderblocks can be a beneficial option, as they help raise the temperature of the garden bed.
Bricks
When it comes to building a raised bed, few materials offer the same level of durability and strength as traditional bricks. Not only do they provide a clean and tidy appearance, but they also help keep crops from spreading beyond their designated area. Whether you opt for engineering bricks or landscaping bricks, both options can suit your needs.
Engineering bricks are particularly well-suited for harsh weather conditions, thanks to their water-resistant properties that prevent moisture absorption. In contrast, landscaping bricks are designed specifically with garden use in mind and can withstand a range of weather conditions and minor abuse.
Cement
While cement can be used to build raised beds, it’s essential to consider its long-term effects on soil pH. On the plus side, this material does an excellent job of preventing weeds from encroaching on your plants, simplifying maintenance tasks in the process. Additionally, cement helps regulate temperatures and retain warmth in the soil during the growing season, which can be beneficial for certain crops. However, its impact on pH levels should not be overlooked.
Metal
One approach is to combine wood and metal in a unique way. For instance, a wooden frame can be used as the foundation, upon which corrugated siding and roofing materials work particularly well. This hybrid design has an added advantage: it warms up the soil slightly, giving you a head start on the planting season. Alternatively, you could opt for a metal frame and construct the walls using wood.
However, keep in mind that most metals have a tendency to rust over time, which may be a consideration when building your mini-greenhouse.
Creating Your Raised Bed
When setting up your raised bed garden, start by selecting a location and positioning the boards accordingly. A general guideline is to keep the bed no wider than four feet to ensure easy access and maintain a safe distance from entering the bed itself. Lengthwise, the options are endless, but consider dividing the space for different plant types or creating separate sections for specific growth requirements.
Think about the root depth of the plants you plan to grow as well – if you want to cultivate long carrots, for instance, a deeper bed (at least a few feet) will be necessary. By considering these factors, you’ll be well on your way to creating a thriving and functional raised bed garden.
Pick the Right Location
When creating raised beds, it’s essential to consider the soil’s sensitivity to foot traffic. Over-stomping can harm plant growth and quality. As a general rule of thumb, maintain a distance of at least four feet from your plants to ensure optimal conditions. If you’re placing the bed near a fence or wall, make it even narrower, considering you won’t have access to one side. The type of plants you plan to grow will also influence the ideal location.
For plants requiring full sun, position the bed in an area that receives direct sunlight. Avoid areas with overhanging eaves or tree canopies that drop fruit or debris. Additionally, steer clear of marshy regions, areas prone to frost, and windy locations, as these conditions can negatively impact plant growth.
Lay Down Barrier Material and Mark the Frame
To begin constructing your raised bed, start by outlining its dimensions using string or chalk. This will give you a clear visual of the bed’s width and length. Once you’ve established these parameters, create a barrier between the soil and the frame by laying down materials like cardboard or landscape fabric. This added layer will prevent weeds from sprouting underneath your raised bed and compromising its structure.
Alternatively, you can choose to build the frame directly on the ground, but be prepared for some unexpected grasses or weeds to make an appearance.
Build the Frame
Regardless of the material you choose for your frame, the initial steps remain similar. When working with bricks, railroad ties, or stone, start by laying down the first layer and gradually build upwards from there. However, if you’re opting for a wood or metal frame, it’s essential to establish a support structure beforehand.
A reliable method for securing your frame involves utilizing rebars – sturdy and long-lasting, with no need to replace them once installed.
Insert one bar into each corner and secure the wood to it. Alternatively, you can connect wooden corners together or invest in metal fencing corner pieces. An additional option is sinking fence posts into each corner.
Once your frame corners are established, you can begin constructing the wood or metal framework between them. For added inspiration, explore the [raised garden bed article](link) for some creative ideas.
Fill the Bed
To complete your garden bed setup, focus on filling it with the right soil. Avoid using topsoil, as it can be dense and lacking in essential nutrients. A better option is to select a raised bed mix from a local nursery or create your own blend by combining equal parts of native soil and well-rotted compost.
If you’re feeling intimidated by the process, consider taking a shortcut by purchasing a metal stock container, drilling a few holes at the bottom for drainage, placing it in the desired location, filling it with the suitable soil, and then planting your chosen flora.
