What is a raised garden bed?

If you have ever seen a garden with a lot of boxes in which the owner grows plants inside, those boxes are probably raised garden beds. They usually have a triangle or square shape, which explains why people refer them to the boxes. They are not a type of planters or containers as they have no bottoms. They are four-sided frames, often made of wood, that can keep piles of soil stay put above the ground.

Why should we use raised garden beds?

  • Aesthetics: Raised garden beds keep your garden well organized. You can put your boxes everywhere you want, and you can decorate the exterior side of them to make your garden look more lively.

We will guide you through each step of the process. But keep in mind that this option involves a harder procedure compared to the first one. Let’s talk about the pros and cons of building raised garden beds from scratch.

  • It can be really expensive if you decide to purchase materials with the highest quality available.
  • It will take you a long time and a lot of effort to set up the frames.

2.1. Choose a size for your raised bed

  • Width: The recommended width is no longer than 4 feet because this will be easier for gardeners to reach the center of the bed from both sides. Also, as the bed is narrow, you can avoid compressing the soil by not having to step on it when gardening
  • Length: Until the width, there is no restrict to the size of the length. If you have enough space, longer beds will be better.
  • Height: Depends on what plant you want to grow. We highly suggest that you search for the root depth of your choice of plant beforehand. The root depths can range from 6 to 36 inches.

2.2. Choose your material

This may be the toughest step because there are tons of selections for you to choose from. We will list some of the best options along with their advantages and disadvantage.

  • Wood: There are also many different types of wood, but make sure that you purchase untreated ones. Some examples are Redwood, Cedar, and Douglas Fir. Wood is very cost effective and easy to build, however, they can only last up to 10 years.
  • Rock: Cheap price (can even be free), but too heavy to lift.
  • Steel: The easiest material to set up but can be expensive.
  • Concrete masonry: Affordable, easy to find and it can last for the longest time out of all the often. It can hold heat, which negatively affects your garden during hot weather.

2.3. Set up your raised garden bed

Step 1: Measure and cut your raw material into four walls for the garden bed by your choice of dimensions. If your raw material is not big enough to obtain full-dimension walls, you can cut it into smaller boards and clamp them together by using the corner posts on their top. Then you can drill pilot holes and attach the posts with screws.

Step 2: Find a flat spot that has maximum sun exposure to put your garden beds on. Try orienting the long side facing south to ensure that the plants in the bed get equal amounts of sunlight. Take all the walls and lay them down on the ground with their inner corners touching.

Step 3: After setting the frame, you will remove the grass inside it. If your land already has soil, you can use a spading fork to loosen it to help your new plants' roots grow deeply into the ground.
