Raised Bed Garden Design Tips

Raised-bed gardens are a popular option for starting a garden. Correct raised-bed garden design helps maximize the productivity of the available space. A well-designed raised-bed garden also adds beauty to your yard.

Gardening with raised beds has several advantages: 

  • The soil mix you fill the beds with ensures the best growing conditions for gardening from the beginning, rather than having to deal with existing soil issues such as rocky or compacted soil. 
  • Drainage issues improve because the growing surface is above the ground level and water drains out easily. 
  • Raised beds warm-up earlier in the spring, allowing you to get a jump on planting

10 Tips for a Successful Raised-Bed Garden Design


Once you’ve decided to add raised beds to your space, follow these ten tips for designing a raised-bed garden to have the best layout for your garden.

1. Pick the best spot in your yard for your raised-bed garden

Look for an area of your yard that gets morning sun; it’s less intense than late afternoon sun. Ideally, the location for your raised-bed garden receives at least 8 hours of sun (you can provide shade if it needs it, but you can’t add sun). 

Other considerations are level ground, good drainage, and access to water. 

Choose your location carefully. Once you have an idea of the dimensions of the garden area, you’re ready to move to the next step.

This area gets morning sun and full sun until late afternoon; it will be a great spot for raised beds.

2. Maximize available space when designing a raised-bed garden layout

Decide how many and what size beds you have room for within the available space. As you choose the size of beds to install, here are a few principles to consider:

  • The beds should be no wider than 4 feet across so you can reach into the center. Beds against walls or fences should be 2 feet across or less. Keeping beds to this size eliminates the need to step in the beds, which causes soil compaction. 
  • The length of a bed doesn’t matter – keep in mind you will need to walk around the bed to get to the other side.
  • Ideally, the depth of the bed is from 12-24 inches deep. Almost all crops can be grown in this depth of raised bed. Most of my beds are 15 inches deep

3. Allow enough space between beds in your raised-bed garden design

 It’s tempting to fill the entire space with raised beds, but paths around the outside of your beds will make planting, maintaining, and harvesting your beds easier. The distance between raised beds should be at least 3 feet wide (4 feet is even better). 

Allowing as much room as possible gives plants room to grow, and also gives you room to get by. Think about if you will need access for a wheelbarrow and plan accordingly. Plants grow quickly, and many plants will overflow and fill in the open space between the beds.

4. Add vertical elements to your garden design

Training plants up a trellis gives you more space to garden, and being off the ground is better for vining plants.

To maximize sunlight, position trellises on the north edge of your garden bed or next to a fence or wall. Alternatively, shade sun-sensitive plants in hotter regions by having a trellis on the south side, filtering the sunlight for plants that need relief from the sun.

5. Take time planning your raised-bed garden design layout

When I was planning my new garden area, the first plan I sketched out seemed alright. However, when I spent time in the space and tried to visualize my plan, I realized it was too crowded and didn’t allow enough space between beds. 

Garden Planning in 5 Simple Steps
  • Make a scaled version of your beds and move them around graph paper.
  • Use an online planning tool to get ideas of the design.
  • Use weed cloth (pictured above) cut to the size of the raised beds to help visualize your design. 
  • It is much easier to move the raised-bed garden layout design around using any of these methods, rather than moving the beds once they are in place. The axiom of “measure twice, cut once” certainly applies here.

6. Choose the best type of material for your beds

Research different types of beds and building materials to understand your options. Always use untreated wood. Beds made with redwood or cedar will last much longer than those made with pine. Rebuilding or replacing your beds every few years is not ideal.

Several factors go into choosing which type of material to use for your raised bed, and the cost is certainly a factor. My advice is to buy the best type of beds you can afford. If you have a garden plan in place, start small and add beds as finances permit.

10 Tips for Designing a Raised-Bed Garden Layout

I added deep-root cedar raised beds from Gardener’s Supply to my garden. Some of the things I love about these beds: 

  • Made from rot-resistant cedar.
  • Extra deep to promote healthy roots.
  • Simple to put together – slide boards into the corners and screw them into place.
  • The aluminum corners keep the beds sturdy and help the beds last a long time – the corners are often the most vulnerable to rot and decay.

7. Add the beds to your space, but wait to fill them

Once the raised beds are in place, walk around the area (what worked on paper may not work in real life). Make adjustments while the beds are empty if necessary. Take time to ensure the beds’ distances are even and the beds are level.

8. Fill the bed with the best type of soil for raised-bed gardens

Regular garden soil is too dense for raised beds. A mix of compost, peat moss or coconut coir, and vermiculite (Mel’s mix from Square-Foot Gardening) is ideal for raised-bed gardens. This post about the best soil for raised-bed gardens explains how to make my favorite soil blend and how to determine the amount of soil each bed will need.

9. Set up your watering system before you plant

Adding a watering system after the fact may disrupt seeds or transplants, and it’s crucial your seeds and transplants don’t dry out. The best way to water a raised-bed garden will provide consistent and even watering, be easy to use and maintain, and ideally be simple to install.

I use garden grids from Garden in Minutes in all my raised beds. Read this post to learn more about the best way to water raised-bed gardens

10. Decide what to plant in your new raised-bed garden

Consider the size of plants when they have fully grown, along with the growth habit of different plants. Vegetables that like to grow vertically should be grown near a trellis, and plants that sprawl should be grown on the edge of the beds so they have room to grow.  Find a reliable planting guide for your area to help you decide what to plant. 

Taking time to carefully go through each of these steps will help your garden not only be productive but look great too. A well-designed vegetable garden adds beauty and bounty to your yard.

Hello. I'm planning the placement of my four 4x8 Garden in Minutes metal raised beds. I'm in zone 9a also in AZ. Does it matter if I orient the beds so the long size faces south or the short end faces south? This will be my main vegetable garden. Thank you for your invaluable website.

Typically beds are positioned with the short side facing south. Best of luck with your garden. I hope you like those beds as much as I do!

Thanks for the great info! Can you explain the difference between choosing a quality wood material, like those cedar boxes, versus metal ones? I'm unsure what the different pros/cons are. Thanks! Also, can you explain what differences you've seen with using deeper boxes rather than the size Mel recommends (in SFG)? I trust your experience, I just wanted to get an idea before I have to spend extra on bigger boxes and more soil. Thank you!

Good question. I'm planning on doing a blog post with more information about the differences between wood and metal beds. I use both and like both. It may depend on where you live for the soil depth. My climate is very hot and dry and the extra depth helps regulate temperature better and retain more moisture.

Do you use landscaping fabric under your raised beds? I want to be as weed free as I can be.

I used landscaping fabric under my beds in areas with Bermuda grass. A thick layer of woodchip mulch helps to keep most weeds down.

Hi Angela. Can you tell me about the buckets you have buried in some of your beds? Are they meant to release liquid fertilizer? If so, how many holes per bucket and how many per bed do you recommend? Thank you!
