Support monarchs and our mission: plant milkweed and wildflowers
A well-crafted border is the backbone of any raised garden bed. It not only defines your planting space with clean, attractive lines but also offers a unique opportunity to support and invite local wildlife into your garden. The right border can provide cozy hideaways and essential resources for beneficial critters.
Using reclaimed, untreated wood (such as cedar or redwood) is a popular, natural choice. Avoid pressure-treated lumber to prevent chemicals from leaching into your garden.
Provides crevices and rough surfaces for insects and small critters
Natural wood can decay slowly over time, offering microhabitats in the process
Readily available and often cost-effective
Warm, natural look that blends well with gardens
Easy to cut and shape for custom designs
Requires periodic maintenance or replacement
Wood may rot over time if not properly cared for
Stone or natural rock borders offer a durable, timeless design.
Crevices and gaps between stones provide shelter for reptiles, amphibians, and insects
Stones retain moisture and can moderate soil temperature, benefitting nearby plants
Provide sunning spots for butterflies, reptiles, and other animals
Extremely durable and low-maintenance
Adds a rustic charm that can enhance garden aesthetics
Non-toxic and environmentally friendly
Can be more labor-intensive and costly to install
Limited flexibility in design once set in place
Using whole or split logs creates a rustic, natural border that integrates seamlessly with garden ecosystems.
Logs offer hiding spots for insects, small mammals, and beneficial fungi
Slowly decomposing logs enrich the soil and provide nesting material for some species
Unique, natural appearance with minimal processing
Durable and can last for many years
Enhances soil fertility as logs decay
May be challenging to source from sustainable, local providers. ChipDrop may be a good option if you are in their service area.
Irregular shapes can make a uniform border design more challenging
Instead of—or in combination with—a physical barrier, consider planting a border of native shrubs, perennials, or even ground covers to define your raised bed.
Offers nectar, pollen, and shelter for bees, butterflies, and birds
Encourages beneficial insects and provides cover for small wildlife
Creates a dynamic, ever-changing border with seasonal blooms
Enhances overall garden biodiversity
Can be integrated with edible or medicinal plants for multipurpose use
May require more initial planning and ongoing maintenance
Plants need time to establish before they fully serve as an effective border
Recycled or composite materials designed for outdoor use can mimic natural textures while offering durability.
Some composites are designed with textured surfaces that can provide microhabitats
Often designed to be inert, reducing chemical exposure to the environment
Long-lasting and resistant to rot
Often low-maintenance
Can be molded into a variety of shapes and designs
May not offer as many natural hiding spots as wood or stone
Look and feel might be less “natural” compared to other options
