What are Stepped Raised Beds?

Stepped raised beds, also known as tiered raised beds, are elevated garden beds that are built with two or more levels or steps. The beds are stacked, with each level sitting above the other like a staircase or set of bleachers.

These stepped planter boxes allow you to make the most of your gardening space by expanding your planting area vertically. The different levels give you more room to grow a variety of flowers, herbs, vegetables, and other plants in a small footprint.

Benefits of Using Stepped Raised Beds

Using stepped raised beds instead of regular single-level garden beds has many benefits, such as:

  • More space for plants—Because they are vertical, stepped beds give you more space to work with. The multi-tier design gives you more space to plant without taking up more land.

  • Better organization – The steps help keep different plants separate and make it easy to organize vegetables, herbs, and flowers. You can designate each level for different types of plants.

  • Improved ergonomics – Stepped beds reduce the need to bend down excessively. The higher levels bring plants closer to eye level, making gardening easier on the back.

  • Enhanced aesthetics – Stepped beds create dimension and visual interest in your garden. The tiered design looks more dynamic than flat single beds.

  • Customizable heights – Beds can be designed with varying step heights to suit the needs of gardeners. Higher beds accommodate taller plants while shorter ones work better for kids.

  • Creative possibilities – Stepped beds allow for countless design options. Beds can be arranged in rows, curves, circles, and more. You can get very creative!

  • Efficient watering – Stepped beds with proper drainage freely shed excess water from the upper levels down to lower ones. Gravity helps distribute moisture efficiently.

  • Sun exposure – The elevated levels allow more sun exposure for plants that need it without shading those below.

Stepped Bed Design Options

Stepped raised beds come in many different shapes, sizes, heights and configurations. Here are some of the most popular stepped garden bed designs:

Linear Stepped Beds

Linear stepped beds feature two or more rectangular levels in a row. This is the most basic and common design, perfect for organizing plants in a line. For example, a 4′ x 8′ stepped bed may have one 4′ x 4′ planter stacked above another 4′ x 4′ planter.

Corner Stepped Beds

Corner stepped beds utilize the footprint of a corner. Two beds are arranged perpendicularly to occupy the corner space. One bed is often longer than the other.

Curved Stepped Beds

Curved stepped beds have a rounded, organic shape. The edges of each tier are curved rather than straight. This creates a smooth, flowing aesthetic.

Circle Stepped Beds

Circle stepped beds are arranged in a concentric circular pattern. Each level is a full circle nestled within the circle below it. This looks visually striking in gardens.

Cascading Stepped Beds

Cascading stepped beds feature dramatically staggered levels that seem to cascade down. Each level is significantly longer and lower than the preceding one.

Pyramid Stepped Beds

Pyramid stepped beds have levels that taper up to a point. Each tier is a bit smaller than the one below it to form a pyramid shape.

Constructing Stepped Raised Beds

Stepped raised beds can be built as DIY projects using lumber or purchased as pre-fabricated garden bed kits. Here are some tips for construction:

  • Choose rot-resistant, non-toxic materials like cedar, redwood, or a wood-concrete composite. This avoids chemicals leaching into soil.

  • Set supporting posts at 4-6 foot intervals around the bed perimeter to reinforce the higher levels.

  • Use corner braces, joist hangers, and screws to securely attach all components.

  • Ensure the higher tier steps back enough from the edge below so plants have sufficient soil depth. 12-18 inches is ideal.

  • Add weep holes at regular intervals around the bottom of each level to allow excess moisture to drain down efficiently.

  • Line the interior of beds with landscape fabric to prevent soil from washing out between levels.

  • Fill each tier fully with enriched gardening soil, leaving ample headspace for plants to grow.

Choosing the Right Stepped Bed Size

Consider the following when deciding on bed dimensions:

  • How much space do you have available? Measure your site boundary.

  • What quantities of plants/vegetables do you want to grow? Bigger beds yield more produce.

  • How will you reach the center? Limit widths to 3-4 feet max for arm’s length access.

  • How many levels will you have? More tiers mean smaller footprints per level.

  • How high will each be? 1-2 feet is common. Match heights to the plants you want to grow.

  • Will you sit/kneel on them? Have at least one short 1 foot bed.

  • How will they be oriented? Long rows or other layouts?

  • Allow for at least 12-18 inches of step back from one level to the next.

Material Options for Raised Garden Beds

Stepped raised beds can be made from different materials. Here are some of the most popular options:


Wood is an attractive, affordable choice. Cedar and redwood are naturally rot-resistant softwoods perfect for raised beds. Avoid treated lumber as chemicals can leach into soil.

Recycled Plastic Lumber

For a maintenance-free option, use lumber made from recycled plastic. It won’t rot, split, or need paint. Colors like timber or weathered gray look like real wood.


Building with natural stone slabs or bricks gives raised beds a sophisticated, permanent look. Granite, limestone, and sandstone are good options.


Poured concrete, concrete masonry blocks, or precast wall units are durable options. Use concrete without harmful fly ash.

Galvanized Metal

Use galvanized steel sheets to construct sturdy, industrial-style raised garden beds with a long service life.

Wood-Concrete Composite

For the best of both worlds, wood-concrete composite is a great choice. You get the look of wood with the durability of concrete.

Choosing the Right Soil Mix

Use a quality potting soil or raised bed mix, not native ground soil which can harbor weeds and pathogens. Here are some soil considerations:

  • Nutrient-rich – Choose a mix with balanced organic nutrients to support healthy plant growth. Avoid soil with synthetic fertilizers.

  • Well-draining – Incorporate perlite or pumice to ensure proper drainage and aeration. Dense or overly rich soil impedes drainage.

  • Lightweight – Look for lightweight soilless mixes to avoid overly heavy loads on stepped beds, which can cause them to bow or deform over time.

  • Moisture-retentive – The mix should hold moisture reasonably well so plants don’t dry out too quickly. Add peat moss, coir, or compost.

  • Regionally-suited – Select mixes formulated for your hardiness zone. Local blends provide nutrients suited to the native environment.

Ideal Plants for Stepped Raised Beds

Here are some great options for planting in elevated stepped garden beds:

Vegetables: Leafy greens, tomatoes, peppers, beans, peas, cucumbers, radishes, carrots, onions

Herbs: Basil, oregano, thyme, sage, rosemary, cilantro, parsley, chives, mint

Flowers: Petunias, marigolds, zinnias, cosmos, snapdragons, dianthus, alyssum, impatiens

Fruit: Strawberries, bush berries, dwarf fruit trees

Maintaining Stepped Raised Beds

Follow these tips for looking after stepped raised garden beds:

  • Check soil moisture frequently and water when top few inches become dry. Be sure to thoroughly saturate the entire depth of each level.

  • Monitor overall soil fertility during the growing season by testing pH and key nutrients like nitrogen, phosphorus, and potassium. Top dress with organic compost or fertilizer as needed.

  • Weed regularly to prevent competition, especially in the corners between steps where weeds can hide. Hand pull weeds or hoe carefully to avoid damaging roots.

  • Watch for erosion between step levels after heavy rain. Refill and tamp down any washed out areas.

  • Prune back overgrown plants, stems, or foliage as needed to keep growth tidy and allow sunlight to reach all levels.

  • Clean up spent plants after the growing season and replenish soil nutrients each year by mixing in 1-2 inches of compost.

Add Beauty and Function with Stepped Raised Beds

With their attractive tiered design and expanded planting capacity, stepped raised beds are an excellent choice for any gardener looking to upgrade their planting beds. Follow the tips above to construct durable stepped beds that will provide an efficient, organized, and aesthetically pleasing garden space for years to come. The pyramid shape makes these planter boxes stand out while offering expanded vertical space to grow more flowers and vegetables in less square footage. Let your imagination run wild combining different heights, shapes and configurations to create a truly unique stepped garden bed feature.

DIY Raised Garden Beds (On a Slope)


What are the disadvantages of raised garden beds?

The cons of raised beds Use rot-resistant wood if you go with boards and figure even those eventually will have to be replaced. The soil mix also can be a significant, albeit one-time, expense. Raised beds need water more often since the soil is more exposed to air and dries quicker.

How many inches deep should a raised garden bed be?

They should have at least 8 inches of soil depth to accommodate the root systems of plants, because the majority of plant roots require 6 – 8 inches of soil for healthy root growth. A depth of 8 – 12 inches will suffice for most gardening situations.

Is it cheaper to make or buy raised garden beds?

On average, a DIY raised bed constructed from wood will cost $25 to $50 per square foot. To have a wooden raised bed constructed and installed for you, budget for at least $100 per square foot. (Find a kitchen garden company in your area.)
