Building A Raised Garden [The Ultimate Guide]

Have you been planning to build a raised garden bed for a long time, but you’ve been afraid to start because of all of the unknowns? Then you are in the right place. This article will alleviate your fears and guide you step-by-step in the process of building a raised garden bed. In addition, it will help you avoid common mistakes made by beginners and even experienced gardeners.

Raised gardens, also called planter boxes, are an excellent choice for growing vegetables and other food items in the backyard of your home. The flexibility to build a garden anywhere is the most notable benefit of raised planters. Moreover, they are a valuable, beautiful, and healthy addition to any home. For people with back pain or knee problems, growing a garden in a raised garden bed is a no-brainer, because it allows you to take care of your crops without bending over.

Some beginners hesitate because they do not know what materials are required and think that building a raised garden will require a lot of time and investment. You can build a raised garden bed using wood, metal, or plastic. Optionally, if building one from scratch yourself isn’t your thing, you can always purchase affordable and easy to put together raised garden bed kits of different materials, shapes, and styles. You can also find horizontal or vertical structures to meet your space requirements as well as planters with wheels for easy movement. Once the raised bed is constructed, don’t forget to use suitable soil. The exact amount will vary depending on the size of your garden bed.

Benefits Of Raised Garden Beds

There are many benefits of raised garden beds. If you are a beginner, I guarantee you will love building your own raised garden. And it really isn’t that hard. The biggest benefit of owning a raised garden bed is that it gives you the freedom to grow your favorite flowering plants, vegetables, and herbs, which sometimes is not possible in a regular garden due to poor quality soil. In raised gardens, you can choose a soil based on the requirements of your crops. A good quality soil helps a plant grow better.

Raised Garden Beds Make Pest Control Easier

Another benefit of a raised garden bed has to do with controlling pests. Pests and weeds harm plants in many ways and sometimes, it becomes so hard to get rid of them that they can destroy your whole garden. Pests may damage or kill your plants and weeds eat up a lot of soil nutrients and slow down the growth of your plants. An important benefit of raised garden beds is that controlling pests and weeds is much easier.

Raised Garden Beds Are Ergonomical

Another benefit is that no bending is required for day-to-day gardening activities. The ergonomics of a raised garden is ideal for your body, which will especially be appreciated by people with issues in their knees and backs. 

Compared to in-ground gardens, raised garden beds cost a little more. However, believe me, it is totally worth it.

How To Build A Raised Garden Bed Step-By-Step

  1. The first step to build a raised bed is to choose the location where you will be planting.  Choose a place where the sun will be shining the whole day, because most plants will need the sun’s rays for their growth. However, some plants like lettuce, spinach, kale, and arugula work well with partial shade too. If you live in a warmer climate, your plants will thrive!
  2. The next step is to choose the wood to build your garden. You can use two planks of wood that are 8 feet (2.4m) long. Cut these in half and make a square bed 4 feet long. A garden bed this size is ideal, as you will not have to step inside the bed to tend to your plants.
  3. The next step is to prepare the ground for planting. Start by laying cardboard over the area where you will be putting the raised garden bed. The cardboard will help in clearing the grass and weeds underneath. Spread the cardboard all over the area to keep it free from grass and weeds.
  4. Now that the ground has been prepared, it is time to make your raised garden bed. With a measuring tape, mark halfway through the planks. Saw both the planks to create the four walls of your raised garden bed. Make sure that they are of equal length.
  5. Next, drill some pilot holes in the plank to screw the walls together. Position your pilot holes in such a way that one end of each plank will overlap the other and screw directly into it. Make it a snug fit.
  6. With your walls fitted, now is the time to fill in your raised garden bed. The soil is the most important part of your garden. The more organic matter there is in the soil, the better. When filling your raised garden bed, look for a soil mix that is at least 40 percent compost, 40 percent topsoil, and 20 percent aeration material. You can find the proper raised garden soil in your local garden center. As for aeration, you will find bagged soil mix already mixed with aerators like perlite, lava rock or pumice.

What You Should Plant In Raised Garden Beds

Now that you have learned how to build a raised garden, it is time to plant your favorite vegetables, fruits, herbs, and flowers. You can also try grouping four or five beds together to make a proper garden. 

Remember, the depth of the soil of your raised garden bed will limit what you grow. Below is what plants grow in what depth.

  1. In a six-inch soil depth, you can grow plants like lettuce, onions, leeks, radishes, salad greens, spinach, strawberries, herbs like chives, basil, mint, cilantro, dill, thyme, parsley, and oregano. Marigold and other annual flowers will also thrive in this soil depth.
  2. In a twelve-inch soil depth, everything that was in the six-inch soil list can be grown. Plus, you can grow beets, cabbage, beans, cauliflower, broccoli, Brussel sprouts, cantaloupe, cucumbers, collards, turnips, garlic, squash, kale, rosemary, lavender, borage, sage, lantana, nasturtiums, cosmos, sweet alyssum, and snapdragons.
  3. Now, we come to the eighteen-inch soil depth. In addition to everything on the six and twelve-inch list, you can additionally grow okra, eggplant, peppers, sweet potatoes, watermelon, pumpkins, and winter squash.

Common Mistakes Made By Beginners

When planning to start a raised garden bed, you may be full of enthusiasm and a lot of energy. And why not? A raised garden bed is much more advantageous and profitable than a normal garden. It offers easy accessibility, you have control over the soil you are putting in the bed, there is considerable improvement in drainage, and the soil is warm enough to guarantee faster growth of plants. Nevertheless, before you start building your raised garden bed, there are some pointers to keep in mind. Some very common mistakes can spoil all your hard work. So to avoid doing so, keep these points in mind:

  1. Just like in real estate, the three most important considerations are location, location, and location. So remember, sunlight is very important for your plant’s growth. They must receive at least six hours of sunlight. Pick a place that is a little flat, but do not choose low-lying areas where rainwater can collect. Also, keep in mind that putting your raised beds against a fence hinders you from accessing it from all sides.
  2. The most common mistake people make when building their raised garden beds is not looking for a water source nearby. If you have to lug around buckets every day to water your plants, your enthusiasm will soon fizzle out. Your garden bed should be near a garden faucet or somewhere you can easily reach with a hose. Watering your plants is very important, so remember that!
  3. You must have the right material to build your raised garden bed. Avoid using material that is prone to decay or wear. Also, avoid chemically-treated lumber because it will release those chemicals into your soil. Go for oak, cedar, redwood, or stones and bricks, which are long-lasting and chemical-free.
  4. You may think every kind of garden soil is best for your garden. However, it is not. You should never use garden soil in a container garden or in a raised planter. Using it in raised garden beds will hinder the drainage process of the plants. Use only bagged soil specifically designed for raised garden beds. This soil also helps kill any weeds, insects, and diseases.
  5. Do not be tempted to make your raised garden bed too big. It should be narrow enough that you would be able to reach halfway across it easily to plant, water, weed, or harvest. Do not make it too long either. It will take you a long time to walk around it. It is better if you create multiple raised garden beds instead of one. 
  6. When selecting the plants for your raised garden bed, do not select very large plants. Understand the scale of growth of the plant with the size of your bed and then plant it. If you have a small raised garden bed, go for dwarf varieties of the plants you want to grow.
  7. Do not skip mulching. Even though raised garden beds are off the ground, they are prone to weeds. Add a layer of mulch to the soil to keep weeds from growing. In addition, mulch also helps in retaining water around your plant’s roots. 
  8. Protect your plants from hungry herbivores. Install fencing to keep deer or other plant-loving animals away from them. You can also use an odor-based repellant on the soil, which will keep these animals away.

Plants grow better and healthier when they are cultivated at places where they get proper sunlight and shade. The raised gardens provide this flexibility, but in-ground gardens do not.

It provides a uniform color to your garden and you can easily give it the shape you want.

Raised Bed with Trellis

If you want your vegetable garden to be neat and tidy, you can try using a trellis or arbor to give them the space to climb up rather than them sprawling on the ground. They are also easier to harvest in this way, allowing you to grow more plants without taking up much space. This design gives the plants access to sunshine too. Just create a simple frame by leaning the structure, tethering two bamboo poles together, and stretching a netting across them.

Raised Beds Lining Walkway

When you have a small yard, even a well-maintained in-ground pathway garden looks cluttered and requires a lot of effort to maintain it properly. To overcome this, building a raised garden bed lining this pathway is a great idea, which makes pathway gardens look beautiful. Moreover, you can plan an all-season look by choosing different plants and planting in such a way that your small garden blooms in every season. You can build garden beds of different shapes using bricks and other materials. With pre-planning, these types of raised beds can make your small space look bigger and provide an awesome view.

You can also build your raised garden bed using recycled material and give it a colorful designer look with paints. There are so many options, however concrete blocks are one of the most widely used and popular. Some gardeners use older cinder blocks, however some oppose the use of cinder blocks as they may contain fly ash, which may be harmful to use around edible plants.

To avoid this ash issue, you can use new blocks of concrete to build your raised garden bed. Then, paint it in your favorite colors. While building such garden beds for planting vegetables, you should be aware of the fact that concrete blocks leech lime, which increases the pH of the soil. Increased pH makes the soil alkaline, so you should select the plants that preferably grow in alkaline conditions.
