How To Build A Raised Garden Bed Using Concrete Blocks

The lower the concrete block set, the better the connection and stability. The majority of backyard gardeners use the 1×4’s decking but think it is simple because they are fairly cheap and it’s a nice looking surface. Concrete is an excellent surface material that can be used to build raised beds as well. Not only it is sturdy enough to hold plants, but also will stay cooler in summer and warmer in winter than wood planks or stones that are easily damaged by frost.

Raised garden beds, also known as garden walls or berms, are a great way to lower the center of gravity in your vegetable garden by adding some structure. By spreading out these traditional building materials over a square foot at a time and then placing them on top of each other, you’ll create a raised area of soil that provides needed drainage without making it difficult to reach into the bed at harvest time.

Raised garden beds are the best way to grow the things you love, in the area where you have space. Here’s how to build your own raised bed using concrete blocks.

Use our instructions to make your own raised bed.

If a raised bed is something you want to make, then here are some instructions:

  • Get enough concrete blocks to build your bed. The amount varies depending on how big your bed will be, but we recommend using one block per square foot of space in the garden so that you have plenty of room for plants while also keeping things sturdy.
  • Make sure that the ground where you’re building is level and stable enough to support the weight of these blocks (and all those veggies!). A simple way to do this is by using a level; place it on top of each corner and take note when they’re all at eye-level with one another, then mark out where each line should go with string or chalk before digging up any dirt from underneath them so there’s no chance that anything could shift during construction or after planting season starts up again next year!
  • Dig out trenches for drainage purposes as well—you’ll want about 6 inches between where soil ends and bottom edge goes down below ground level (and 4 inches between top edges). This will help prevent water buildup underneath if rains come unexpectedly heavy during summer months! You can also use pipes instead if necessary but keep in mind what type would work best depending on soil type & climate zone requirements needed before making final decisions here.

Choose Your Size.

There are a few things to consider when choosing the size of your raised garden bed. The first is how much space do you have available in your yard? If you have only a small area to work with, then it may be best to go with a smaller sized raised garden bed. You should also think about how much space you will need for each vegetable or flower so that they can grow without being crowded out by other plants.

The next step is deciding on the length and width of your raised garden bed. This should be based on what kind of crops or flowers will be planted in them, as well as their spacing requirements. For example, if you want to plant lettuce next spring then that crop will need quite a bit more room than some herbs like parsley which don’t spread out very far from their original planting location

Plan The Construction.

  • Plan the size of your raised bed.
  • Plan the depth of your raised bed.
  • Plan the height of your raised bed.
  • Plan the width of your raised bed.
  • Decide on a location for your new garden, and calculate how many blocks you’ll need to complete it

Lay Out The Raised Bed.

Lay Out The Raised Bed

Use a tape measure to measure the dimensions of your raised bed. Mark the corners of your bed using stakes and mason’s line. You’ll be digging a trench for the edge of each wall, so make sure you leave enough room for this when you’re measuring out your site. Make sure to use a level as you are digging so that you get an even grade all around. If there are any large rocks or roots in the way, move them out of the way before digging begins so that they don’t get stuck under concrete blocks later on.

Dig The Trench.

  • Take a shovel and dig a trench, 12 inches deep and 12 inches wide. Make sure you use the shovel to dig down 6 inches below the surface of your soil so that you can bury your block in place without having to move it later on.
  • If using a rototiller instead of hand digging, use a garden hose to wash away loose dirt before raking over the base with a spade to level it off so it’s flat enough for your seedlings or plants to grow on top of without them sinking into soft ground beneath them

Cut Paver Stones To Create A Level Base.

Before you begin your raised garden bed project, it’s important to create a level base for your garden bed. You can use pavers or stones for this purpose. To cut these materials, you’ll need a masonry saw or chisel. You can also use a concrete saw and chisel if working with concrete blocks instead of pavers or stones.

Add Gravel And Blocks.

Add Gravel And Blocks

Now that you’ve got your frame set, it’s time to add some gravel. The purpose of adding gravel is to help with drainage and prevent roots from growing into the soil. If you don’t have any, you can use regular old dirt instead. If you want to get fancy, there are different types of gravel that will work better than others—but we’re not going to go into that here. For now, just grab some rock or sand at your local hardware store and put it in the bottom of each container before placing blocks on top of it.

Once all your beds have been filled with block bases and covered with 1″ (2 cm) or so of coarse aggregate (gravel), use a level to make sure everything is nice and level before proceeding! Now start filling your containers with soil by shoveling away from yourself so as not to spill any precious nutrients onto hard surfaces outside the bed area where bugs won’t be able to eat them up easily without walking through water first.

Make It Sturdy.

To make sure your new garden bed is sturdy, you’ll want to check the level of your foundation before you begin building. A good way to do this is by using a laser level, which will produce an accurate line on the ground that can help guide your construction.

Once you have the foundation laid out and leveled, it’s time to start building! The first step is laying down a layer of concrete blocks so that they’re all touching each other (or nearly touching). The next step is adding gravel between each block—this allows water to drain through easily and prevents weeds from growing up through the soil below it. Finally, add another layer of concrete over all these materials in order for them to be strong enough for plants’ roots later on down the road.

Building a raised garden bed can help you grow the plants you love in the area where you have space to grow them.

Building a raised garden bed can help you grow the plants you love in the area where you have space to grow them. You can build a raised garden bed yourself, either by hand or with concrete blocks.

A raised garden bed is simply an elevated container for planting your vegetable and herb plants. They’re easy to make out of concrete blocks or pavers, both of which are commonly available at home improvement stores like Lowe’s and Home Depot.

Final words

There you have it: the step-by-step instructions for building your own raised garden bed using concrete blocks. This project is easy enough that anyone can do it, and you can make it as big or as small as you want. You’ll soon be on your way to growing your favorite plants, herbs, or vegetables in the space that works best for you.
