Raised bed procedure: How to set one up

Raised beds can be found in small city gardens, but also in private gardens in the countryside. Why are they an increasingly popular form of planting compared to standard ones? They offer greater comfort when working, better conditions for plants, and easier control over soil composition. If you are interested in how to create a raised bed yourself, without unnecessary expenses, you have come to the right place. In the article you will find a detailed raised bed procedure, advice on choosing material and practical tips for its maintenance throughout the season.

For storing tools, substrates or seasonal garden accessories, you can also practically use durable tarpaulin sheds, which will protect the material from rain and sun.

How to build a raised bed yourself

Building a raised bed does not require any special expertise or a gardener with many years of experience. All you need is enough free time, basic gardening tools, and commonly available materials. This way, you can build it yourself and calmly even over the weekend. The advantage of building it yourself is that you can adjust the size and height according to your needs and possibilities. Follow these steps:

Choose a suitable location

A suitable location for a raised bed should be sunny, ideally facing south or west, with at least 6 to 8 hours of sunlight per day.Make sure there is access to water and a sufficient distance from trees with a powerful root system.

Bed dimensions

The recommended width of a raised bed is 80 to 120 cm, so that you can comfortably reach the center of the bed from both sides. The length is adjusted to the space, the height depends on the type of crops grown – for herbs and lettuce, 30 to 40 cm is enough, for root vegetables at least 60 cm.

Choose the material

The most common material used to make a raised bed is wood (spruce, pine, acacia), which is affordable and easy to process. For a more durable solution, bricks, concrete blocks, stone or recycled plastic can be used. Avoid chemically treated wood, which can release harmful substances.

Remove the grass and level the base

How to establish a raised bed so that the process is as smooth as possible? At the beginning, carefully remove the grass and roots so that they do not grow into the flower bed later. Level the surface of the substrate with a hoe or rake, or create a gentle slope for rainwater drainage. If you are dealing with uneven terrain or need to adjust the slope near your garden, we recommend that you check out the article: Slope reinforcement: How to do it yourself and without much expense.

Build a structure

Connect the sides into a rectangle using screws, reinforcements and metal brackets for greater strength. Reinforce the corners with prisms. If you use wood, we recommend painting it with a protective coating before assembly, e.g. varnish, linseed oil or ecological water-based impregnation. For a longer service life, you can line the inside with a nub foil or geotextile.

For protection, storage of building materials and for building structures in adverse weather, it is worth using practicaltarpaulin sheds, which will provide shelter from rain and sun.

Raised bed procedure – How to do it without unnecessary costs

How to create a raised bed if you don’t want to spend a lot of money unnecessarily? There are several ways to make a raised bed cheaply and effectively:

• Pallet wood: You can use old pallets as the basic structure for a raised bed. Just disassemble them, sand them, and treat them with an ecological moisture-proof paint. Pallet wood is usually strong and readily available, often free.
• Old boards and beams: If you have leftovers from a renovation, demolition, or old furniture, they can be transformed into a solid and stable bed. Just cut off the damaged parts, sand them, and adjust them to the desired size. This way you recycle material for a new raised bed that would otherwise end up in a landfill.
• Without a bottom: If the raised bed is not on a concrete surface, there is no need to build a bottom. The direct connection to the soil will allow plants to draw moisture from the lower layers and supports the natural cycle of nutrients. At the same time, it reduces costs and simplifies soil replacement in the future.
• Compost instead of substrate: Fill the lower layers of the raised bed with branches, grass, leaves and kitchen biowaste. Instead of expensive garden substrate, you can also use decomposed homemade compost, which significantly reduces the cost of filling the bed. In addition to saving money, you also support the recycling of organic waste.

How to make and build a raised bed from wood or boards

The most common and at the same time most affordable option for making a raised bed is to build it from wood or wooden boards.You can also use practical ship containersto store them or temporarily store tools during construction, which offer a durable and safe solution for gardeners and craftsmen. Let’s take a look at what you’ll need:

Materials

For a raised bed measuring 120 × 80 × 40 cm, you’ll need approximately 4 boards measuring 120 cm long, 4 measuring 80 cm long, and 4 measuring 40 cm high,plus corner braces, which can be made of wood or metal. The wood should be dry and free of rot or insect damage. Boards with a thickness of at least 2.5 cm are suitable, ideally up to 3 cm.

Tools

When building a raised bed, you will need a cordless screwdriver, a saw (ideally a miter saw for precise cuts), a spirit level, a tape measure, a pencil, and fasteners (wood screws, metal angles, or clamps). When working with hardwood, it is worth pre-drilling holes to prevent the material from cracking.

Joining

Start by assembling the side walls. Place the boards on a flat surface and join them into a rectangle.Use a spirit level to ensure the walls are straight and perpendicular. Reinforce the corners of the raised bed with prisms (e.g. 5 × 5 cm), which you fasten from the inside of the structure. In the case of longer beds, we recommend adding reinforcements to the middle of the longer sides so that the boards do not bend over time.

Wood protection

You can line the inner walls of the raised bed with a nub foil, which protects the wood from moisture from the soil and extends its lifespan.An alternative is geotextile, which is also water-permeable. Before assembly, coat the wood with a protective coating – linseed oil, varnish or special ecological coatings without toxic substances are suitable. It is not recommended to use chemically pressure-impregnated wood if the bed is used to grow edible plants.

The lifespan of a raised bed is 5 to 8 years, with quality wood and regular maintenance (e.g. annual renewal of the coating) it can be even longer. When using hardwood such as acacia, the structure can last up to 10 years. If you choose wood-plastic, we are talking about a lifespan of 12 to 15 years, while it does not require any further maintenance.

Raised bed filling procedure – What goes to the bottom, what goes to the top

For the proper function and long-term fertility of a raised bed, the correct layering of individual materials is key. This principle mimics the natural process of decomposition of organic matter in the soil and at the same time ensures optimal drainage, aeration and nutrient supply. For covering larger areas where we prepare the substrate or store the soil, tarpaulin sheds can also be a practical solution. Here is a proven raised bed and filling procedure:

• At the bottom: Coarse material – branches, twigs, bush cuttings and thinner trunks (layer approx. 20 to 30 cm). This bottom layer acts as a drainage layer, allowing excess water to drain and reducing the risk of waterlogging the roots. In the case of higher beds (over 50 cm), it is recommended to use larger pieces of wood, which will decompose gradually and provide heat and nutrients over a long period of time.
• Next layer: This is followed by finer organic material – grass, dry leaves, kitchen bio-waste (e.g. vegetable peelings) and manure. This layer is approximately 10 to 20 cm thick and serves as a nutrient base that will support the activity of soil microorganisms and decomposition.
• Compost: Well-rotted compost from a home composter (15 to 20 cm) is an ideal intermediate layer. It contains stabilized nutrients and microorganisms that positively affect the soil structure. You can spread the compost evenly or mix it with manure from the previous layer.
• Garden substrate: The top layer is made of high-quality garden soil or ready-made substrate with the addition of humus or perlite for better permeability. The layer should be at least 20 to 30 cm, and when growing root vegetables, it can be even more. If you buy substrate in a store, choose one without peat or with an organic production certificate.

A bed prepared in this way is immediately ready for planting or sowing.Layers naturally settle and decompose over time, so it is advisable to replenish the top layer of substrate by 5 to 10 cmevery spring. Regular replenishment of organic matter (e.g. compost) will ensure long-term fertility and a healthy environment for your plants.

Raised flower beds – how to do it – Maintenance and use during the season

The use of raised flower beds is really varied – they are suitable forgrowing a wide range of vegetables and herbs: from tomatoes, peppers, lettuce, radishes and spinach, through herbs such as basil, chives, parsley or mint, to strawberries, onions, garlic and carrots. Thanks to better soil and microclimate control, they are also suitable for more demanding plants and pre-growing seedlings. You can also effectively use practical shipping containers to store tools, soil or seasonal equipment. So what is the maintenance and use of raised beds?
