Gardening is a great way to relieve stress in a productive way. After all, you are the creative mastermind behind your garden.
A popular method for gardening is using a raised garden bed.
A raised garden bed is when a plot of soil is placed into a bed above the surrounding soil.
This bed is often blocked off with planks of wood and has its own special soil mixture. Not every soil is created equal, and the best soil for raised garden beds can be hard to find.

What is the Best Soil for Raised Garden Beds?
Every gardener wants to create the best soil for their plants. Without it, there’s not a big chance of a fruitful season for your flowers or trees. This is especially true for raised garden beds.
Raised garden beds are completely separated from the soil in the ground. So, it’s up to the gardener to create the perfect soil. How they do this depends on a few things.
The best soil for raised garden beds depends on what you want to grow. If the plant you’re looking for thrives in acidic soil, you need to add components to make the soil ideal. Similarly, if your plant loves a more basic pH level, you need more balancing agents in your soil.
Additionally, you need to take the weather into consideration. If it’s very dry where you live, you might need to add soil that retains moisture well. If your area receives a good amount of rain, make sure you have a good drainage system.
So, the best soil for your raised garden bed depends on what you want to grow and the area you live in. You make your soil from scratch, so make sure to create a combination with these things in mind.

How much Soil for Raised Garden Beds?
With raised garden beds, the soil is the main factor for success. You want to have a perfect balance of it. Too much soil runs over and gets wasted, while not enough soil harms plant growth.
The amount of soil you need depends on two things: the height of your raised garden bed and the plants’ root depth. Taking a look at the height of your raised garden, a common choice is around 11”.
With a height of 11”, your raised garden bed has plenty of room to drain properly. That starts you off needing around a foot of gardening soil. This amount increases depending on how many square feet you have in your garden bed.
On a similar note, you can make your garden a bit taller to ease back pain or a bit shorter for your own preference. If you choose to do this, you’re going to have to adjust your soil amount accordingly.
Moving on to the factor of root depth, roots are the main reason behind the soil you need for your raised garden bed. Your plant needs to have enough room underneath to spread out and collect its food. How deep of a root depth you have depends on what you’re growing.
Some vegetables, like lettuce, have very short roots. They don’t need to go very far down the soil to get the strength and nutrients they need. In this case, you don’t need to have a lot of soil in your raised garden to accommodate them.
On the other hand, plants like tomatoes need lots of room to spread out their roots. So, you’re going to need more soil for them to grow properly. The bottom line is, the amount of soil your garden needs depends on how you design your garden and what you grow in it.
How to Prepare Soil for Raised Bed Vegetable Garden?
Once you’ve figured out what you want to plant in your raised garden, it’s time to get the land ready. Any good gardener knows that it’s very rare for a part of the land to be ready for planting at any given moment.
The first step in planting is almost always fixing up the land and making it ideal for plant growth.
Prepare the soil: With raised garden beds, you have a bed of land that’s separated from other parts of the soil horizontally. But vertically, the soil is still on top of the native soil. That means that your plants are able to access the soil underneath the raised bed.
For this reason, gardeners who want raised beds need to prepare the soil underneath. It’s better to do this step before you set up the perimeters for your bed boundaries.
Start by digging the soil about two feet deep in. Turning over the soil helps you understand what you’re working with. You can see if the land underneath is dry or if you have roots from other plants already in place.
You can then adjust your soil accordingly by adding fertilizer or removing any roots or rocks in the way. This process of digging beforehand gives your plants the best chance to grow healthy.
Perfect the soil: After you’ve dug through and removed any obstructions, it’s time to perfect that soil. If you noticed that the soil was very heavy and difficult to move, you can add peat moss to lighten it. Similarly, if the pH level for that soil is off, take this time to adjust it.
Once your soil is good for planting, go ahead and build your bed on top. Fill up the inside with your starter soil, and allow a few inches of free space on top.
When you have about a week left until you add the plants, top it off with fertilizer and compost. You want to add these a few days before you plant, so they don’t wash away or go too deep into the soil. After these steps, you’re ready to get started with your raised garden bed!
5 Tips for Improving Your Raised Bed Garden Soil
Starting any new gardening task takes time, especially for new gardeners. Perfecting the craft of gardening takes a lot of hard work and dedication.
But these tips should ease some of your worries and provide you a little guidance along the way.
1. Know What You’re Working With
The best way to create the best soil is to understand what you have in front of you. Learn as much as you can about the soil you currently have.
Check out the pH levels, test the soil for density, and figure out if there are intruding roots in it. Learning about your soil tells you how you can help growth and improvement.
Once you know what it’s missing, follow through with it consistently. You can’t change soil with one helping of fertilizer, so consistency is the key to getting results.
2. Organic Fertilizer is the Way to Go
Speaking of fertilizer, many people think that any old fertilizer is fine. While it’s true that you can use any fertilizer, the best fertilizer is the organic type.
Chemical fertilizers do provide results, as you can see a change in your soil within weeks. But they do nothing to help the soil around your plants, and in a raised garden, the soil is key.
Organic fertilizers not only help the plants, but they help the soil around them as well. If you’re trying to build up your raised garden soil, organic fertilizer takes care of both.
3. Figure Out Your Soil’s Past
This tip is especially important for new gardeners. Oftentimes, you buy a bag of soil thinking that it’s going to help your garden bloom instantly, but to no avail. Then, you learn that you actually got a soil that needs to be fortified, aka dirt.
Anyone can sell dirt, and dirt is not what your raised garden needs to grow. Ask your seller where the soil came from before buying it. When you know where it’s been, you can understand what it needs to grow better.
With this information, you can add nutrients to that dirt to turn it into a soil your plants thrive in. But without it, it’s just plain dirt.
4. Compost is Cool
One thing that every gardener should get in to is composting. Composting is the way to turn any dirt into hospitable soil for your plants.
When it comes to composting, people either think it’s rocket science or a glorified trash can. It’s actually neither. Composting is about collecting biodegradable leftovers and turning them into live fertilizers.
People think that composted material smells bad or is difficult to manage, but not if you do it correctly. If that’s an issue, you can buy bins made specifically for compost to help enclose the smell. Composted material is treasure for your plants, the soil, and the ecosystem around it all.
5. Everyone Needs a Refresher
Everyone needs a little pick-me-up every now and then, including your soil! During the first years of using a raised garden bed, you might notice that it’s doing very well. That’s because your soil has a lot of new nutrients and other goodies to give at the time.
But once you grow the plants for that year, your soil is pretty much running on empty. You need to revitalize it with the help of some extra soil inputs. These could be fertilizer spikes, compost, or leaf mold.
Work these into the soil by turning over the old soil and gradually adding one of these components. Finish it off with a good helping of fertilizer, and you’re well on your way to great new planting year.
As with anything good in life, you need patience when you get into gardening. When you understand what your soil needs, you can add or take away things to create the best raised bed soil. Understanding your garden takes time, but once you master it, you can create a wonderland.
