Menards Landscape Timbers
Menards landscape timbers are AC2® pressure treated pine timbers designed for outdoor landscaping applications. Unlike structural lumber, landscape timbers are used for garden borders, raised garden beds, retaining walls, and pathway edging.
Menards carries landscape timbers in two standard treated wood lengths:
- 4 ft treated landscape timber — ideal for small garden borders, raised beds, and tight corners
- 8 ft treated landscape timber — the most popular size for long garden beds, retaining walls, and edging
These timbers are typically 3.5″ × 5.5″ in cross-section (rough cut) and treated to Ground Contact (UC4A) level so they can be partially buried in soil without rotting. They stack easily and can be secured with rebar or landscape spikes for retaining walls up to 3 courses high.
Menards also carries an AC2® 5×5×8 rough sawn timber — a heavier option for load-bearing retaining walls or raised garden beds that need extra strength. At roughly $12–$18 per 8 ft timber, it is an affordable alternative to railroad ties or concrete edging.
Menards Landscape Timber Size & Price Guide
| Product | Size | Length | Treatment | Best For | Approx. Price |
|---|---|---|---|---|---|
| Treated Landscape Timber | 3.5″ × 5.5″ | 4 ft | Ground Contact | Small borders, raised beds | $4–$7 |
| Treated Landscape Timber | 3.5″ × 5.5″ | 8 ft | Ground Contact | Retaining walls, long edging | $8–$12 |
| AC2® Rough Sawn Timber | 5″ × 5″ | 8 ft | Ground Contact | Heavy retaining walls | $12–$18 |
| Black Plastic Timber | Varies | 8 ft | N/A (recycled plastic) | Permanent borders, no rot | $10–$15 |
Installation tip: For retaining walls, pre-drill holes and drive 18-inch rebar through the timbers into the ground every 4 feet to prevent shifting. Overlap corners like brickwork for stability. For raised beds, a single course of 8 ft timbers on each side handles most vegetables.
If you want a maintenance-free option, Menards also stocks black plastic landscape timbers made from 98% recycled materials — these never rot, crack, or splinter, ideal for permanent garden edging where wood deterioration is a concern.
