Landscape timbers are one of the most affordable and versatile materials for outdoor projects. They're commonly used for garden borders, raised flower beds, retaining walls, walkway edging, and decorative steps. The final price depends heavily on the timber's dimensions, wood species, and treatment type.
Cost by size
Landscape timbers come in several standard dimensions, and the size you choose directly affects the per-piece cost. Smaller timbers work well for garden edging, while larger ones are suited for structural applications like retaining walls.
| Timber size | Common use | Price per piece (8-foot length) |
|---|---|---|
| 2 x 4 inches | Light edging, borders | $3 – $6 |
| 3 x 4 inches | Garden beds, walkways | $4 – $8 |
| 3 x 5 inches | Raised beds, edging | $5 – $10 |
| 4 x 6 inches | Retaining walls, steps | $8 – $15 |
| 6 x 6 inches | Heavy retaining walls, structural use | $12 – $25 |
| 6 x 8 inches | Large retaining walls | $18 – $35 |
The most popular size is the 3 x 5 x 8-foot pressure-treated pine landscape timber, which typically retails for around $5 to $10 at major home improvement stores. This size provides a good balance between cost, weight, and versatility for most residential projects.
Timbers also come in lengths beyond the standard 8 feet. Twelve-foot and 16-foot timbers are available but cost proportionally more, usually $10 to $40+ per piece depending on the cross-section dimensions.
Cost by material type
The type of wood or composite material significantly influences both the upfront cost and the long-term durability of landscape timbers. Pressure-treated pine is the most common and affordable option, while hardwoods and composites command premium prices.
| Material | Price per 8-foot timber | Lifespan |
|---|---|---|
| Pressure-treated pine | $4 – $10 | 10 – 20 years |
| Cedar | $10 – $25 | 15 – 25 years |
| Redwood | $15 – $35 | 20 – 30 years |
| Douglas fir (treated) | $8 – $18 | 10 – 20 years |
| Composite/recycled plastic | $12 – $30 | 25 – 50 years |
| Railroad ties (used) | $15 – $30 | 20 – 30 years |
Let's take a closer look at the most popular material options and what each brings to the table.
Pressure-treated pine
Pressure-treated pine is the industry standard for landscape timbers. At $4 to $10 per 8-foot piece, it offers the best value for most projects. The treatment process forces preservatives into the wood, protecting it from rot, insects, and fungal decay.
These timbers are rated for ground contact and non-structural use, making them ideal for flower beds, garden borders, and light retaining walls up to about 2 feet tall. They typically last 10 to 20 years before needing replacement.
If you're building raised beds for growing edible plants, choose timbers treated with ACQ (alkaline copper quaternary) or CA-B (copper azole type B). Older CCA-treated (chromated copper arsenate) timbers are no longer sold for residential use due to arsenic concerns but may still be found in existing structures.
Cedar
Cedar landscape timbers cost $10 to $25 per piece but offer natural resistance to rot and insects without chemical treatment. This makes cedar a popular choice for raised vegetable gardens and projects where a natural appearance is desired. Cedar also weathers to an attractive silver-gray over time.
Composite and recycled plastic timbers
Composite landscape timbers range from $12 to $30 per piece and are made from recycled plastic, rubber, or a blend of wood fibers and plastic. They won't rot, split, or attract insects. While the upfront cost is higher, these timbers require virtually no maintenance and can last 25 to 50 years, making them a strong long-term investment.
Cost by project type
The total cost of a landscape timber project depends on the number of timbers required, additional materials like rebar and gravel, and the complexity of the build. Below are estimated costs for common residential projects.
| Project type | Materials cost | Installed cost (with labor) |
|---|---|---|
| Garden border (50 linear feet) | $50 – $150 | $200 – $500 |
| Raised flower bed (4 x 8 feet) | $60 – $200 | $200 – $600 |
| Raised vegetable garden (4 x 12 feet) | $100 – $350 | $300 – $800 |
| Timber steps (4 to 6 steps) | $150 – $400 | $500 – $1,500 |
| Small retaining wall (up to 25 linear feet, 2 feet tall) | $200 – $600 | $800 – $2,500 |
| Large retaining wall (50+ linear feet, 3 to 4 feet tall) | $500 – $2,000 | $2,500 – $5,500+ |
| Driveway or walkway edging (100 linear feet) | $100 – $300 | $400 – $1,000 |
Simple single-layer borders are the most affordable projects. You'll need roughly 7 timbers per 50 linear feet of border when using standard 8-foot timbers, which translates to about $50 to $100 in materials alone.
Retaining walls are the most expensive timber projects because they require multiple stacked layers, rebar or deadman anchors for structural support, gravel backfill for drainage, and sometimes professional engineering. A wood or timber retaining wall replacement with treated timbers can run $5,500 or more for larger installations.
Installation and additional material costs
Beyond the timbers themselves, most projects require supplementary materials and hardware. These extras can add $50 to $500+ to your total project cost depending on the scope.
| Material or supply | Average cost |
|---|---|
| Rebar spikes (12 inches, per piece) | $1 – $3 |
| Timber screws/landscape spikes (per box) | $10 – $30 |
| Gravel for drainage (per ton) | $25 – $60 |
| Landscape fabric (per roll) | $15 – $40 |
| Drainage pipe (per 10-foot section) | $5 – $15 |
| Construction adhesive (per tube) | $5 – $10 |
| Wood stain or sealant (per gallon) | $20 – $40 |
| Soil or fill dirt (per cubic yard) | $15 – $50 |
Professional labor costs
Hiring a landscaper or contractor to install landscape timbers typically adds $40 to $75 per hour in labor costs, or roughly $150 to $500 per day per worker. Most professionals charge either by the hour or by the project.
For a basic garden bed installation, expect to pay $100 to $400 in labor. Retaining walls require more skill and time, with labor alone running $500 to $3,000+ depending on the wall's height and length. Walls taller than 4 feet may require a structural engineer's stamp, adding $200 to $500 to the total.
Cost factors
Several variables determine the final cost of a landscape timber project. Understanding these factors helps you budget more accurately and identify opportunities to save.
| Factor | Impact on cost |
|---|---|
| Timber size and length | Larger dimensions cost more per piece |
| Wood species | Cedar and redwood cost 2 to 4 times more than treated pine |
| Treatment type | Non-treated timbers are cheaper but last half as long |
| Project complexity | Retaining walls cost significantly more than flat borders |
| Site preparation | Sloped or rocky terrain increases labor time |
| Geographic location | Timber prices vary by 10% to 30% regionally |
| Quantity purchased | Bulk orders may qualify for contractor discounts |
| Delivery | Adds $50 to $150 unless self-hauled |
Regional price differences
Timber prices fluctuate based on your proximity to lumber mills and regional supply. In the Pacific Northwest and Southeast, where pine and softwood forests are abundant, prices tend to be 10% to 20% lower. In the Northeast and Mountain West, costs can be 15% to 30% higher due to shipping and limited local supply.
Seasonal pricing
Landscape timbers are cheapest in late fall and winter when demand drops. Spring and early summer bring the highest prices as homeowners start outdoor projects. Shopping off-season can save you 10% to 15% on materials.
DIY vs. hiring a professional
Simple landscape timber projects like garden borders and small raised beds are well-suited for DIY. More complex builds like retaining walls over 2 feet tall are better left to professionals due to structural and drainage requirements.
| Approach | Best for | Estimated savings |
|---|---|---|
| DIY | Garden beds, edging, small borders | 40% – 60% vs. hiring a pro |
| Professional installation | Retaining walls, steps, complex grading | Higher cost but proper engineering |
A DIY raised garden bed using pressure-treated timbers might cost $60 to $200 in materials. The same project installed professionally would run $200 to $600. The primary tools needed for a DIY timber project include a circular saw, drill, level, tape measure, and a rubber mallet.
When stacking landscape timbers for a raised bed or low wall, drive 12-inch rebar stakes through pre-drilled holes every 4 feet to anchor each layer to the one below. Stagger the joints between layers like bricks for added stability. Always place the first course of timbers on a level, compacted gravel base.
Buying tips to save money
Smart shopping and project planning can reduce your landscape timber costs by 15% to 40%. Here are practical strategies to stretch your budget further.
- Compare prices across retailers. Prices for the same 8-foot treated timber can vary by $2 to $5 between stores like Home Depot, Lowe's, Menards, and local lumber yards.
- Buy in bulk. Many lumber yards offer 5% to 15% discounts on orders of 20 or more timbers. Some also provide free delivery on large orders.
- Shop off-season. Late fall and winter purchases typically save 10% to 15% compared to spring pricing.
- Inspect before buying. Reject timbers that are warped, cracked, or excessively wet. Choosing straight, dry timbers reduces waste and installation headaches.
- Consider alternatives. For purely decorative borders, smaller 2 x 4-inch timbers at $3 to $6 each may be sufficient instead of the larger 4 x 6-inch sizes.
- Check clearance sections. Retailers often discount timbers with minor cosmetic imperfections by 25% to 50%.
- Skip delivery when possible. Most standard 8-foot timbers fit in a full-size truck bed. Delivery fees of $50 to $150 can equal the cost of several timbers.
Frequently asked questions
How long do landscape timbers last?
Pressure-treated pine landscape timbers typically last 10 to 20 years depending on soil moisture, climate, and ground contact. Cedar lasts 15 to 25 years, and composite timbers can last 25 to 50 years. Applying a wood sealant every 2 to 3 years extends the lifespan of natural wood timbers.
How many landscape timbers do I need?
Divide the total linear footage of your project by the timber length (usually 8 feet). For a simple 32-foot garden border, you'd need 4 timbers per layer. For a 2-layer raised bed measuring 4 x 8 feet with a perimeter of 24 feet, you'd need 6 timbers (3 per layer). Always purchase 10% extra to account for cuts and waste.
Are pressure-treated timbers safe for vegetable gardens?
Modern pressure-treated timbers using ACQ or copper azole preservatives are considered safe for raised vegetable beds by most university extension services. The EPA banned CCA-treated wood for residential use in 2003. For extra peace of mind, line the inside of treated timber beds with heavy-duty plastic sheeting.
What are the alternatives to landscape timbers?
Common alternatives include concrete retaining wall blocks ($3 to $6 each), natural stone ($5 to $15 per square foot), steel or aluminum edging ($2 to $5 per linear foot), and brick ($0.50 to $1.50 per brick). Each option has trade-offs in cost, appearance, durability, and ease of installation.
| Alternative material | Average cost |
|---|---|
| Concrete retaining wall blocks | $3 – $6 each |
| Natural stone | $5 – $15 per sq ft |
| Steel or aluminum edging | $2 – $5 per linear ft |
| Brick | $0.50 – $1.50 per brick |
How do you secure landscape timbers together?
The most common method is driving 12-inch rebar stakes through pre-drilled holes to pin each layer to the one below. You can also use timber screws (8 to 10 inches long), galvanized spikes, or construction adhesive between layers for added strength. For retaining walls, deadman anchors extending back into the hillside provide critical lateral support.
