Starting a raised bed garden is an excellent way to embark on a rewarding gardening journey. Whether you have limited space, poor soil quality, or physical limitations, a raised bed offers a versatile and accessible solution. 

In this blog post, we will cover the key aspects of starting a raised garden bed and guide you through the whole procedure. 

What is a Raised Bed Garden?

A raised garden bed is essentially a self-contained garden plot that is elevated from the ground level. This garden setup involves a solid frame made from various materials such as wood, stone, concrete, or even creatively repurposed items.

The height of the raised bed can vary, with some being a few inches tall, merely demarcating the garden area, while others can be several feet high, providing ease of access for planting, watering, and weeding.

In addition, the inside of this framed structure is then filled with a nutritious blend of soil, compost, and other organic matter.

While starting a raised garden bed, you’ll still need to employ similar steps on how to start a garden but the beauty in this case is that it allows you to maintain a separate, richly fertile soil environment for your plants, distinct from the ground soil. 

Benefits of Raised Bed Gardening

1. Portability

Raised bed gardening enables you to position their beds in your most desired location, irrespective of soil conditions.

Traditional gardening is limited by the quality and location of the existing soil. Still, with raised beds, you can garden on patios, driveways, or areas with poor soil. You can even move them around if needed.

2. Easier Accessibility

Raised beds require less bending over than traditional gardens, making them ideal for seniors, people with physical disabilities, or anyone who wants to ease the strain on their back and joints. The beds can be made to any height, providing comfort and ease when planting, weeding, or harvesting.

3. It Improves Drainage

Proper soil drainage is crucial to plant health as it helps prevent waterlogging-related diseases. Raised beds elevate the soil above ground level, allowing excess water to drain away more efficiently than in in-ground beds. This is particularly beneficial in areas with heavy clay soil, which tends to retain water.

4. It Enhances Better Soil Quality

With raised beds, you have complete control over the soil within the bed. You can fill the bed with the ideal soil blend for the crops you intend to grow, whether rich, loamy soil for vegetables or a sandy blend for succulents.

Also, because you don’t walk on the soil in a raised bed, it doesn’t get compacted, which is better for plant roots.

5. Warmer Soil

Soil temperature is a vital factor in seed germination and plant growth. In raised beds, soil warms up more quickly in the spring and stays warm longer into the fall. This extended growing season means you can plant earlier and harvest later, increasing your overall yield.

6. Raised Beds Provide Some Degree of Pest Control

Certain pests, such as slugs and snails, are less likely to cross the boundary of a raised bed, and the added height can deter some ground-dwelling pests.

Furthermore, it’s easier to add barriers such as copper tape or netting to a raised bed than to a traditional garden plot.

7. Raised Beds Offer Superior Weed Control Compared to Traditional Gardens

You start with a weed-free environment by filling the bed with new, clean soil. The height of the bed makes it harder for weeds to invade from surrounding areas.

Also, because raised beds are more compact, it’s easier and quicker to spot and remove any weeds that do appear.

Steps on How to Start a Raised Bed Garden 

1. Identify the Location

Start by assessing your outdoor space. Remember, most vegetables and flowers require a minimum of six to eight hours of direct sunlight each day, so placing your raised bed in a location that receives ample sunlight is essential.

The area should also be easily accessible for watering and maintenance. If you live in the northern hemisphere, the south side of your garden is generally the sunniest, while for the southern hemisphere, it’s the north side.

2. Choose the Size and Material of Your Bed

The size of your raised garden bed should depend on the space available and what you plan to grow. A common size is 4×8 feet, which offers ample space for a variety of plants and is still narrow enough to reach the center from either side. 

Height is also a consideration – aim for at least 6-12 inches deep to accommodate most plant roots. However, 24 inches is ideal for deep-rooting vegetables.

The material for your bed can range from wood (avoid pressure-treated varieties to avoid chemical leaching), stone, concrete blocks, or even recycled plastic. Each material has pros and cons related to durability, cost, and aesthetics, so choose one that best fits your needs.

3. Prepare the Site

First, remove any grass or weeds from where you plan to place your bed. Then, use a level to ensure the ground is flat.

If it’s not, you may need to dig or add soil to even it out. This is essential as the uneven ground may lead to uneven water distribution within the bed. 

Once cleared, laying down a weed barrier cloth can be beneficial to prevent any remaining weed seeds in the ground from sprouting. Cover this with a layer of mulch like wood chips or gravel to further suppress weed growth.

4. Assemble Your Bed

Using your chosen materials, assemble your raised bed according to the manufacturer’s instructions or your own design.

Make sure it’s sturdy and secure. If you’re using wood, you might want to line the interior sides with a layer of plastic to reduce rotting. Leave the bottom open to allow for proper drainage and root growth.

5. Fill Your Bed

When filling your bed, think in terms of layers. Start by filling the bottom third with bulky organic material like twigs, branches, leaves, or untreated lawn clippings. This ‘green waste’ will decompose over time and provide valuable nutrients for your plants. 

The middle third can be filled with older soil, spent compost, or partially decomposed compost. The top third should be filled with high-quality garden soil mixed with compost or well-rotted manure.

This layering not only provides a nutrient-rich environment for your plants but also helps keep the costs down.

6. Plant Your Garden

Depending on what you’re planting, you may fill the bed right to the top and then sow seeds or dig individual holes for transplanting seedlings.

Aim to plant densely to maximize yield and minimize weed growth. Also, consider companion planting, where certain plants are grown together for mutual benefits, such as pest control or enhanced growth.

7. Care for Your Bed

Finally, remember to water regularly, especially in the first few weeks after planting, and top up with fresh compost or manure each season to replenish nutrients.

Essential Tips for Raising a Garden Bed

• Choose a location that receives at least six to eight hours of sunlight each day. If possible, also select a spot with easy access to water since your raised bed will need regular watering.

• If your bed doesn’t drain adequately, it can become waterlogged and harm your plants. If necessary, you can improve drainage by adding coarse materials like gravel or sand to your soil mix.

• Since you’re controlling the environment in a raised bed, take the opportunity to use high-quality soil. Mix compost or well-rotted manure to enrich the soil and promote healthy plant growth.

• If you’re growing vegetables, plan to rotate your crops each year. This practice helps to prevent soil-borne diseases and replenishes nutrients.

• Mulch the surface of your raised bed to help conserve moisture, suppress weeds, and add organic matter to the soil. You can use straw, wood chips, leaves, or compost as mulch.

• Consider companion planting – growing certain plants together for mutual benefit. Some plants can deter pests from their partners, while others can enrich the soil by fixing nitrogen.

• Even with high-quality soil and compost, your plants may need additional nutrients as they grow. Use an organic, all-purpose, or tailored fertilizer, depending on your growth.

• Remove any weeds as soon as you see them, keep the bed clean of plant debris, and prune your plants when needed.

• If bending or kneeling is difficult, consider a higher raised bed or even a table garden. Ensure you can reach the middle of the bed without straining.

• Consider using a hoop house or cold frame over your raised bed in colder climates to extend the growing season.

• Raised beds tend to dry out more quickly than in-ground gardens, so monitor soil moisture carefully, especially in hot, dry weather. A drip irrigation system or soaker hose can be water-efficient to ensure your plants get the moisture they need.

What Soil is Best for Raised Beds?

For raised beds, sandy loam is an excellent choice due to its unique characteristics that make it particularly suitable for this kind of gardening.

Sandy loam is a blend of sand, silt, and a smaller proportion of clay. This combination creates a soil structure that is loose and well-draining, which is vital for healthy plant roots. It allows for the easy movement of water and air, preventing issues related to waterlogging or compaction, which can stifle plant growth.

Moreover, sandy loam can retain the right amount of water needed for plants to thrive without the soil becoming waterlogged. It strikes a fine balance between drainage and water retention.

Also, sandy loam is known for its high organic matter content, making it rich in nutrients that plants need for healthy growth. It provides an excellent environment for beneficial microbes to thrive, leading to a healthier and more productive garden.
