You’ve graduated from Legos in the playroom. You may just be ready for landscaping blocks in the yard. With fast and easy installation, landscaping blocks are an excellent way to spruce up an old flower bed, hilly terrain, or dull backyard. 

Landscaping blocks can help you create various features for your yard ranging in style, utility, texture, material, and color. They provide many fun projects for DIY masterminds and are a piece of cake for any professional you need to call in for the job. 

Cozy fire pits, outdoor kitchens, walking paths –– we’re sharing with you 18 landscaping block ideas that plastic Legos won’t stand up against. 

What are landscaping blocks?

Landscaping blocks, wall blocks, landscaping bricks, and pavers are construction blocks typically existing in various block shapes, sizes, materials, and textures. 

Many landscaping and wall blocks have a self-locking flange in the back, a lip that overhangs and grasps the block underneath. The flange allows for easy, fast installation when stacking these blocks to make a wall or other landscape structure. 

You typically don’t need an adhesive or mortar when stacking landscaping or wall blocks, thanks to the locking flange’s help. But this will vary depending on the landscape project and the blocks you use. 

Some examples:

Landscaping blocks, wall blocks, and landscaping bricks: Use these for building a retaining wall or freestanding wall around your yard or garden. These blocks can also make raised beds for your vegetable gardens or flower beds. 

Pavers: These are excellent blocks for designing and installing flat surfaces, such as patios or walkways. You can also use them as landscaping or wall blocks, depending on the project. 

18 landscaping block ideas for your yard

1. Retaining wall 

Is erosion a problem in your landscape? Build a retaining wall around your problem spot with retaining wall blocks.

So how does a retaining wall work? 

When no retaining wall is present, rain (or heavy winds) tends to wash away soil. The decline in the soil can expose delicate plant roots and cause the area to erode over time. A retaining wall helps to hold the soil in place and prevent erosion. 

2. Wall caps

Wall caps are the finishing touch to your retaining wall, like a frame around a beautiful picture. They aren’t necessary for a retaining wall to do its job, but they can add an extra dose of curb appeal. 

To keep the retaining wall caps in place, you may want to opt for an adhesive or sealant. 

3. Showcase an outdoor lighting feature

Landscape lighting ensures your green lawn doesn’t disappear into the night. And a small stand provides your lighting fixture a place to shine. 

Stack your chosen landscaping blocks to make support stands for your favorite decorative lamps. Build them along pathways, driveways, or patios so your lamps can light up the landscape after the sun goes down. 

4. Stacked retaining walls

Landscaping on a hill? Don’t let its big size fool you. There are plenty of ways to landscape on a slope, and one method is to use stacked retaining walls. Retaining walls are useful for erosion control, but they also help make hilly areas more level, making for easier design. 

Better yet, the cascading view of stacked retaining wall systems can be attractive to the eyes, especially when you plant colorful flowers throughout each level.

5. Fire pit

Craving more fun evenings outdoors with the family? It may be time for a backyard fire pit. Make it with landscaping blocks and wall caps for a rustic design that blends well with the surrounding outdoors. 

A fire pit is a great addition to any backyard landscape. It creates a cozy ambiance for warm conversation, hot chocolate, and delicious s’mores. 

6. Fireplace

If a fire pit is too small for the entire family, build a grand fireplace with landscaping blocks.

A fireplace will fit right into your outdoor living space and make for exciting evening entertainment. The crackling fire will have you nestled outside for hours, and your party guests will love the dramatic effect. 

7. Landscape edging

Does mulch keep spilling out of your flower beds after heavy rain or a windy day? Edge them with some landscaping bricks.

Edgers help to keep that mulch in check and accentuate your flower beds with clear, concise borders. 

8. Flagstone walking path

Flagstones are like flat landscape building blocks. Lay them down in the landscape for a charming walking path that leads to the garden or directs visitors to the backyard. 

A walking path helps keep people off the grass, provides a safe course of travel, and steers visitors toward lawn areas you can’t wait to show off. 

For added texture and appeal, fill the space between your flagstones with pea gravel or river rock

9. Freestanding wall

Walls don’t always have to be holding in soil or performing erosion control.

Freestanding walls are designed to stand alone. They can help divide parts of the landscape, such as a garden wall or patio wall,  and provide aesthetic appeal, privacy, or low standing seating areas.

10. Paver patio

Install brick paver blocks to create that patio you’ve been dreaming of. You love your backyard, but a new patio will have you loving it even more. 

A patio sparks more opportunities for new landscape additions. Why not set up an outdoor dining area for meals in the warm sun? Or perhaps you’d like to install an outdoor kitchen or grill for countless afternoons of outdoor entertainment.

A new patio has more to offer than just a flat surface. 

11. Walking path

Give your front lawn a makeover with a paver walkway. A walking path leading to the front door helps keep stomping feet off your green grass and delicate flower beds. 

Live in a house with two front doors? A walking path to the main entrance will help ensure visitors know where to ring the bell. 

For extra safety, light up your walking path with small landscape lights. 

12. Edge a dry creek bed

After heavy rainfall, downspouts create plenty of polluted runoff that can run straight into your gardens or waterways. Redirect the runoff with a dry creek made of river rock, and hold the bed in place with some brick edging. 

The varying river rock colors of browns, grays, and beiges contrasted with the red brick will make a prettier site than eroded earth. 

13. Raised flower beds

Have your flower beds not been catching the neighbors’ eyes? Change up things with raised flower beds that will make your flowers stand out from the rest of the neighborhood lawns. 

Pick a landscaping block style that goes well with your perennials’ and annuals’ texture and color scheme. 

Why build a raised garden bed? Raised beds, whether for your flowers or vegetables, help you better control the soil type, keep out contaminants, make invasion harder for pests, and perform easy-access maintenance.

The landscaping blocks will also act as a retaining wall to keep the soil in place. 

14. Stairs

A simple set of stairs provides easy access to your home. 

Avoid slippery slopes, melting snow, or wet mud on your way to the door, particularly at night time when it becomes harder to see where you’re walking. 

15. Cinder blocks

Have leftover cinder blocks from a recent landscaping project? Keep them out of the landfill and put them to good use in your garden. 

Stack them similar to landscaping blocks, and you can make supportive beds for your flowers and vegetables. 

16. Outdoor kitchen

You’ve been wanting an outdoor kitchen, but some designs you’ve looked at are far past your budget. Consider using landscaping blocks to ease the financial burden. 

An outdoor kitchen is an asset to any landscape. Cooking on the grill allows for healthy meals, burning smells don’t get trapped in your house, and the cook needn’t miss out on the fun happening in the outdoor dining area. 

Outdoor kitchens also help reduce the stress on your air conditioner, as indoor kitchens always have a way of cranking up the heat. 

17. Porch columns

Turn your outdoor living space into a comfortable shelter with an outdoor rooftop that protects you from rain and the hot sun. 

The rooftop will likely need some supporting block columns. If your living area features a hardscape design, like natural stone, match the supporting column material with the hardscape design. 

Your block columns will likely need an adhesive to maintain safe stability. A job like this may require the skills of a professional. 

18. Poolscape

When it comes to revamping the lawn with landscaping blocks, don’t forget about the poolscape.

Give your swimming pool a makeover with a brand new brick patio, raised garden beds, and stacked retaining walls.

Highlight the texture of your landscaping blocks’ with a dry rock garden, shrubs, ornamental grasses, or a succulent garden

FAQ About Landscaping Blocks 

How much do landscaping blocks cost?

How much you spend on your landscaping blocks and building materials will depend on your project’s size and the block material you choose. 

Most landscape wall blocks are sold per pallet at home improvement stores. At Home Depot, a pallet of landscaping blocks ranges between $500 and $1,000. 

If you prefer to buy per block, Lowe’s offers retaining wall blocks ranging between $2 and $5 each. 

Need pavers? Paver blocks will typically cost about $2 each or range between $300 and $900 per pallet. 

Can I install landscaping blocks myself?

If you’ve got the skills, time, and tools, landscaping blocks can make great DIY projects. Most landscaping blocks have a built-in flange that makes stacking and stability simple and easy, particularly for retaining wall projects.

Check out Lowe’s step-by-step instructional video on how to build a retaining wall. 

Remember that you may need to acquire a builder’s permit before building a tall retaining wall. Your local building codes or homeowners’ association guidelines may determine your retaining wall’s (or similar landscape project’) size, location, and safety measures. 

Building a large retaining wall? You may want to leave the height to the professionals. Without the necessary skill set, building a tall wall can be dangerous. 

How many landscaping blocks do I need for my project?

To estimate how many blocks you will need, determine how many blocks you will require per row. To do this, divide your project’s total length (retaining wall, fire pit, walkway) by the block’s length. 

Next, determine how many rows you’ll need by dividing the project’s height by the height of the block. 

Pro Tip: Remember that the first row will most likely be half-buried. 

When to call a professional

Installing landscaping blocks may be easy for some, but not everyone. If you haven’t got these specific hardscaping skills in your DIY toolbox, call a local landscaping professional near you.
