For raised bed vegetable gardening, Mel's Mix is the best soil to use. Square Foot gardening author Mel Bartholomew simplifies the best soil to use for raised bed vegetable gardening in his book Square Foot Gardening.
For square-foot gardening success, you should follow Mel's mix instructions, which he calls "the most important, productive, essential, necessary, critical" ingredient. Then, dig into know the best-raised bed soil.
What is raised bed soil?

Raised beds are made from a mixture of topsoil and compost, which is then used to create the planting medium. The plants grow in this medium, and you must use good-quality garden soil for your raised beds.
You can ensure that your raised bed soil has all the nutrients your vegetables and other crops require. This means they will grow well and have higher yields and better taste.
The Best Soil for Raised Bed Gardens:
My favorite vegetable garden soil comprises a mix of 1/3 topsoil, 1/3 compost, and 1/3 peat moss (or coconut fiber). In addition to being well-draining, the soil we add to this mix can also retain moisture and be packed with the nutrients your plants will need to grow healthy.
Large bales of peat moss are often available for a reasonable price at local hardware stores or garden centers. However, finding good-quality topsoil and compost can be difficult. Burnco (in Alberta) and other local companies may be able to help you fill large raised beds.
It is not uncommon for these companies to sell garden soil that has already been mixed. You should be able to find something like the recipe for the garden soil above in it.
How to Fill a Deep Raised Bed Garden?

If you live in a cold climate as I do, you probably don't want to use peat moss because it doesn't hold enough water. Peat moss is great for growing plants that prefer moist conditions, such as ferns and cacti. But for most vegetables, peat moss isn't ideal because it dries out quickly. So what else can you use?
Well, there are lots of options. You could use shredded leaves, grass clippings, pine needles, sawdust, wood chips, coffee grounds, and many others. There's no hard and fast rule about how much stuff you add to your raised beds, but here are some guidelines:
- For every 4 square feet of area, add 3 to 5 cubic yards of materials.
- For every 8 square feet, add 4 to 7 cubic yards.
- For every 12 square feet, add 5 to 9 cubic yards.
- Don't add anything that will burn or smolder.
- Be sure to check local regulations regarding waste disposal.
What are the benefits of raised bed soil?
1. Raised bed soil warms up faster in the spring, allowing you to get a jump on the gardening season.
2. The soil in raised beds drains better than in traditional gardens, so your plants will never sit in soggy conditions that can lead to root rot.
3. Because of their improved drainage, raised beds are less likely to experience compaction from foot traffic, meaning your plants will have more room to grow healthy roots.
4. The soil in a raised bed can be customized to perfectly suit the needs of your plants, giving them a leg up on growth and health. You can also control the pH level more easily in a raised bed than in an open garden plot.
5. Raised beds allow you to plant more densely, which makes it easier to harvest larger amounts of food per square foot of land.
6. They're safer than conventional gardens.
7. They're cheaper to maintain.
8. They require far fewer pesticides and fertilizers.
Raised beds provide several advantages over traditional gardens, including:
1. They warm up quicker in the spring, making it easier to start seeds indoors before they reach outdoor temperatures.
2. They drain better than traditional gardens, preventing standing water from rotting roots.
3. Their compacted nature means that the roots of your plants have plenty of space to grow without becoming overcrowded.
4. The soil can be customized to suit the specific needs of each type of plant.
5. They create a safe play environment for children and pets while providing easy access for parents and caregivers.
6. Their compacted nature allows them to withstand higher levels of foot traffic.
7. They're cheaper to build and maintain than traditional gardens.
8. They require far fewer chemicals and pesticides.
Types of raised beds:
You can choose between two types of raised beds: plastic and wooden. Plastic raised beds are inexpensive and durable, though they take longer to heat up in the spring. Wooden ones are heavier, more expensive, and last much longer.
Plastic raised beds come with a few drawbacks:
- They can harbor pests.
- They aren't always convenient to move around.
- You'll need to buy new plastic liners if you decide to move your garden elsewhere.
- They're not as versatile as wood-framed raised beds.
They must be placed at least 1 inch above ground level to make them work best, just like a regular garden.
Wooden raised beds are made from untreated lumber and feature solid, rectangular frames covered with thick wood slats. These raised beds are sturdy, heavy, and long-lasting but require some maintenance. If you live in hot climates, you should paint or stain the beds yearly. In colder areas of the country, you may only need to repaint your beds annually.
As with any garden tool, care must be taken when using power tools near these wood beds, especially during the winter months. When cutting down trees, ensure that the tree is already dead and has been properly removed from the forest floor.
How to choose the best-raised bed soil for your garden?

When choosing the best soil for your raised garden bed, there are a few factors to consider. The first is the type of plants you want to grow. Different plants have different soil requirements. For example, some plants prefer sandy soil, while others prefer clay soil.
The second factor to consider is the drainage of the soil. Good drainage is important for raised garden beds because excess water can pool in the bed and drown the roots of your plants. If you live in an area with heavy rains, you may want to consider a raised bed with a built-in drainage system.
The third factor to consider is the nutrient content of the soil. Nutrient-rich soils will help your plants grow healthy and strong. For example, suppose you plan on growing vegetables in your raised garden bed. In that case, you'll want to ensure the soil has plenty of nitrogen, phosphorus, and potassium (NPK).
Best Soil Types:
Now that you know what factors to consider when choosing a raised bed soil, let's look at some of the best soil types for raised garden beds.
One of the best soil types for raised garden beds is compost. Compost is rich in nutrients and helps improve drainage while also retaining moisture. It's also relatively inexpensive and easy to find.
Another good option for raised garden beds is topsoil. Topsoil is the top layer of soil that contains most of the nutrients plants need to grow. Therefore, it's important to choose topsoil that is high quality and free of chemicals, pesticides, and herbicides.
The third option for raised garden beds is potting mix. Potting mix is a lightweight, sterile mix that is often used for container gardens. It drains well and doesn't compact easily, making it ideal for raised garden beds.
No matter which type of soil you choose, be sure to add some organic matter like compost or manure to help improve the nutrient content and drainage of the soil.
How to maintain raised bed soil?

Fertilize your raised beds in the spring and summer with a balanced fertilizer, such as 10-10-10. Then, apply the fertilizer according to the package directions.
Weeding: Hand-pull weeds as soon as you see them. Be sure to pull up the entire root so the weed doesn't grow back. You can also use a hoe to chop weeds down at the soil level.
Mulching: Mulch around your plants with organic material, such as bark chips, straw, or shredded leaves. This will help keep the soil moist and prevent weeds from growing.
Watering: Water your raised beds deeply and regularly during the growing season.
