Did You Know?
1. Certain fish species, such as koi and catfish, can help maintain the health of a raised garden bed by consuming harmful insects and larvae that may be present in the soil.
2. One innovative option for the bottom of a raised garden bed is using old wine bottles. Placing them upside down, nested together, creates a firm structure that improves drainage and aeration while adding a unique visual touch.
3. Before adding soil to a raised garden bed, a layer of newspaper or cardboard can be laid down to act as a weed barrier. Over time, this will break down and enrich the soil with organic matter.
4. To promote healthy plant growth and prevent waterlogging, it is advisable to install a perforated drainpipe at the bottom of the raised garden bed. This allows excess water to drain away effectively, avoiding root rot and other water-related issues.
5. Incorporating a layer of wood chips or straw at the bottom of a raised garden bed can help with moisture retention and reduce the need for frequent watering. Additionally, it acts as insulation, protecting plant roots during extreme weather conditions.
Cheaper And Eco-Friendly Alternatives To Fill Raised Garden Beds
Many gardeners are seeking cost-effective and environmentally friendly ways to fill their raised garden beds. One approach is to calculate the amount of soil needed to reduce waste. Another popular method is the hugelkultur technique from Germany, which involves layering organic material such as compost and woody materials to create fertile soil.
The hugelkultur method offers several benefits for raised garden beds. By incorporating materials like rotting logs, sticks, grass clippings, coffee grounds, and compost, gardeners can improve soil quality and enhance drainage. When selecting wood for the hugelkultur bed, it is recommended to use sticks instead of logs and decomposed wood for easier breakdown.
For optimal results, certain types of hardwoods are suggested for the hugelkultur bed, including birch, alder, maple, cottonwood, willow, and oak. However, it is important to avoid allelopathic trees like black walnut, red oak, and sycamore, as well as rot-resistant trees like black cherry and black locust. These trees can impede the decomposition process and impact plant growth.
Using The Hugelkultur Method For Improved Soil Quality
The hugelkultur method involves digging a trench about 1 meter deep and filling it with large logs. The logs create a mound-shaped raised garden bed that helps with soil retention and drainage, especially in urban areas with poor soil quality. This method is cost-efficient compared to buying bags of soil from a store, saving a substantial amount of money.
It is important to ensure that the wood used in the hugelkultur bed is starting to rot. This can be obtained from dead tree branches or abandoned wood piles. Large pieces of wood should be placed at the bottom of the bed, as they take the longest time to decompose. Smaller pieces should then be layered on top to fill the remaining space. The final layers should consist of compost and topsoil for planting.
While termites may be attracted to the buried wood, it is important to note that they typically live in standing dead trees rather than buried logs. Garlic can be grown alongside the hugelkultur bed to help deter pests, and regular vigilance is necessary to address and control pests like slugs, snails, and pill bugs.
Alternatively, for those looking for a convenient and ready-to-use option, Vego raised garden beds provide an excellent alternative to the hugelkultur method. These beds do not require digging a trench or placing a fence around the bed, making them ideal for those with space limitations or physical constraints. Softwoods can also be used in Vego raised garden beds.

Vermicomposting And Organic Fertilizer For Raised Garden Beds
Vermicomposting is another method besides hugelkultur that can greatly enhance the quality of soil in raised garden beds. Vego Garden offers an in-ground worm composter for easy collection of worm castings, which can be used as an organic fertilizer. Vermicomposting not only enriches the soil, but also promotes a healthier and sustainable gardening practice.
By utilizing kitchen waste and organic matter, vermicomposting provides a continuous supply of organic fertilizer for plants. The resulting worm castings are nutrient-rich and can significantly improve plant growth and overall soil health. Including vermicomposting in raised garden beds ensures the presence of beneficial microorganisms and increases the availability of essential nutrients for plant uptake.
Avoiding Plastic Or Trash Bags For Better Drainage
While it may be tempting to use plastic or trash bags as a liner for raised garden beds, it is important to avoid them as they hinder drainage and can contaminate the soil with plastic particles. These materials do not allow for proper water drainage, leading to waterlogging and potential root rot.
Instead, it is recommended to opt for natural drainage methods in raised garden beds. These can involve using pea gravel or other porous materials to allow excess water to drain freely. This helps prevent fungal diseases and promotes a healthier growing environment for plants.
Understanding The Benefits And Maintenance Of Hugelkultur Beds
Hugelkultur beds offer numerous benefits for gardeners. Not only are they cost-efficient and eco-friendly, but they also improve soil quality, retain water, and create a mini biosphere with microorganisms, fungi, and insects that enhance soil health. Additionally, hugelkultur beds require minimal maintenance once constructed.
It is recommended to occasionally add a couple of inches of compost and organic fertilizers to replenish the beds. Weeding is minimal due to the organic matter suppressing weed growth. Hugelkultur beds can be built in both sunny and shady locations, making them versatile for growing various types of plants, including vegetables, herbs, and fruits.
However, it is important to note that root vegetables like carrots and tubers may have difficulty growing in hugel beds due to the depth requirements and the potential disruption of the bed’s structure. It is advisable to consult plant tags and garden catalogs for specific climate requirements of other plants intended to be grown in hugel beds.
Overall, understanding what to put on the bottom of a raised garden bed is crucial for optimal growth and drainage. Embracing techniques like the hugelkultur method, utilizing vermicomposting, and avoiding plastic or trash bags can significantly enhance the success of your raised garden beds, providing a sustainable and productive gardening experience.

Frequently Asked Questions
What is best to put on bottom of raised garden bed?
Another option is landscape fabric. This material is specifically designed to prevent weeds from growing, making it a popular choice for raised garden beds. It allows water to drain through, while still creating a barrier against pests and unwanted plants. Additionally, you can consider using plastic sheeting. Although it is not the most environmentally friendly option, it can effectively keep pests and weeds at bay. However, be aware that plastic may not allow for proper drainage, so you may need to create additional drainage holes in your raised garden bed.
Do raised beds need a bottom?
While it may seem logical to have a bottom in a raised bed to contain the soil, it is not necessary. In fact, having an enclosed bottom can limit the potential growth of plant roots as they cannot extend into the ground for additional nutrients. By leaving the raised bed open to the ground, plant roots have the freedom to explore and access nutrients from the soil beneath, promoting healthier and more robust plant growth. So, when it comes to raised beds, just say no to bottoms!
What is the best filler for the bottom of a raised bed?
When it comes to choosing a filler for the bottom of a raised bed, organic compost and materials are an excellent choice. The addition of compost not only improves soil fertility and structure but also enhances water retention and drainage. You can experiment with different ratios of compost and organic materials to customize the mix according to your specific gardening needs. Additionally, consulting experts at your local nursery or garden store can provide valuable recommendations on organic mulch, compost, or topsoil options that will work effectively in your raised beds.
What is the best liner for raised beds?
The best liner for raised beds is landscape fabric or cloth fabric from clothing. These materials are durable, readily available at garden supply stores, and effectively prevent toxins from leaching into the soil. Unlike non-porous plastic, landscape fabric and cloth fabric allow proper water drainage and enable beneficial insects and worms to thrive, promoting a healthy ecosystem in your raised bed.
