In urban environments, trough planters introduce greenery without the need for pavement excavation. Their rectangular silhouette makes them an excellent alternative to traditional fencing, effectively defining boundaries or guiding pedestrian traffic in open spaces. To ensure longevity, select materials like granite that can withstand heavy traffic and harsh weather conditions.

This guide is part of our Trough Planters Guides Resource Hub, alongside other in-depth resources.

Shape Up Your Style

The first step to designing with trough planters is considering the form that best suits your space and desired effect:

Long and Low

The classic silhouette of long and low trough planters excels at defining spaces. Line walkways, create borders, or frame patios with these elongated planter boxes to create a sense of direction and structure. For a modern, sleek look, choose planters with clean lines and minimalist designs. If you prefer adding some rustic charm, opt for rectangular planters in earthen colors or have a washed finish. The length of the trough planters allows you to play with scale and proportion so you can enhance the visual dynamic of your space.

Tall and Slender

Elevate your design with tall, slender planters flanking doorways or accenting corners. These planter boxes add a touch of vertical drama, perfect for showcasing low-growing plants like grasses, ferns, or small shrubs. The height of these planters draws the eye upward, creating a sense of grandeur and elegance. Additionally, they can be used to frame entrances, guide pathways, or create focal points in your landscape.

Tiered Tapestry

Create a dynamic composition by using trough planters of varying sizes in a tiered arrangement. This approach not only adds visual interest but also maximizes vertical space utilization. Arrange different heights and widths to create a layered effect, allowing each planter box to stand out while contributing to a cohesive design. This tiered setup is ideal for small spaces where horizontal space is limited, as it allows you to add depth and dimension without overcrowding the area.

Elevated Planting

Elevated planting involves raising trough planters to waist height using stands, legs, or custom-built frames. This improves accessibility for gardeners with mobility limitations, reduces strain from bending, and can define spaces at seating level. Elevated planters also improve drainage and deter some ground-level pests.

Material and Color

The material and color you choose for your trough planters can have significant impact on the overall aesthetic of the design.

Classic Materials for a Timeless Touch

Embrace a classic aesthetic with concrete trough planters. They add warmth, texture, and a sense of rootedness to your design. Concrete planter boxes are known for their durability and contemporary look, able to withstand the elements while adding a modern touch to your landscape. Their sturdy construction makes them ideal for both indoor and outdoor settings, providing a robust foundation for your plant arrangements.

Fiberglass Trough for a Modern Twist

For a contemporary twist, explore lightweight options like fiberglass. This material offers durability without the added weight, making the planters easy to move and arrange as needed. Fiberglass planter can come in a vibrant spectrum of colors or subdued monochromatic scheme.

Using Mixed Media

Don’t be afraid to combine different materials! Juxtapose a weathered concrete trough with a sleek fiberglass planter box one for a unique look. This mixed media approach adds texture and contrast which creates a visually engaging design. By pairing different materials, you can highlight the distinct qualities of each planter box. Experiment with various combinations to find the perfect balance between rustic and modern, traditional and contemporary.

Material and Finish Considerations

When selecting trough planters, consider how material and finish impact both durability and aesthetics. Fiberglass resists cracking and is lightweight. Concrete and stone offer permanence and thermal mass. Corten steel develops a rustic patina over time. Powder-coated aluminum provides a clean, modern look with minimal maintenance. Matching finishes to your architectural context ensures a cohesive design.

Planting Design

Once you’ve selected your trough planter, it’s time to unleash your creativity with different planting options:

Mass Plantings

Trough planters are ideal for creating mass plantings of flowers, herbs, or low-growing shrubs. Choose plants with similar light and water requirements for a cohesive and thriving display. For instance, combine a variety of flowering annuals like petunias, marigolds, and geraniums for a vibrant, season-long color show. Alternatively, plant a mix of culinary herbs such as basil, thyme, and rosemary to create a functional and fragrant herb garden. The elongated shape of the planter box allows you to plant densely so you can achieve a lush, full appearance.

Succulent Symphony

For a low-maintenance explosion of color and texture, create a succulent symphony in your trough planter. The variety of shapes, sizes, and colours in succulent plants allows for endless design possibilities. Mix and match species like echeveria, sedum, and aloe to create a visually striking arrangement. Succulents’ ability to thrive in shallow soil makes them perfect for planter boxes. Their drought-tolerant nature means less frequent watering. Enhance the design with decorative stones or gravel to complete the look.

Culinary Canvas

Transform your trough planter into a stylish haven for your favourite herbs. This keeps your culinary companions close at hand and adds a touch of vibrant life to your kitchen or patio. Plant herbs such as parsley, cilantro, mint, and chives in your planter box. Arranging them based on their growth habits and light requirements. The convenience of having fresh herbs within reach will inspire your cooking. The variety of textures and scents will enhance your outdoor living space.

Planting Pointers

A few key considerations will ensure your trough plantings thrive:

Drainage Matters

Ensure your trough planters have adequate drainage holes to prevent water-logging and root rot. Proper drainage is essential for the health of your plants, as it prevents excess water from accumulating at the bottom of the planter box. If your planter doesn’t have drainage holes, consider drilling some or using a layer of gravel at the bottom to facilitate water movement.

Focal Flair

Use a tall trough planter to highlight a statement plant or small tree. This creates a focal point that draws the eye and adds a touch of drama to your landscape design. Choose a plant with striking features, such as a Japanese maple, ornamental grass, or a large flowering shrub, to serve as the centrepiece of your planter box. Surround it with complementary plants to enhance the overall composition and create a balanced, harmonious design.

Vertical Gardening

Rectangle trough planters are excellent bases for vertical gardening. By installing trellises, cages, or wire grids into the planter, you can grow climbing plants like jasmine, clematis, or pole beans. This maximizes small footprints and transforms blank walls or fences into lush, green backdrops.

Use of Trough Planters in Commercial and Public Spaces

Planter boxes can add greenery to an urban area without having to dig up pavement and can be good alternatives to fencing. Because of their rectangle shape and ability to create a barrier, trough planters are useful in open spaces to guide pedestrian traffic. Choose trough planters that can withstand damage from traffic and outdoor weather conditions. Planters made from granite are especially durable.

Streetscaping

You can see trough planters used in the streets of Queen’s Quay in Derry City as a barrier for pedestrians. At the same time, the planters allow for planting perennials in a bustling cityscape.  These granite planters are durable enough to withstand some punishment from pedestrians and small trolleys.

Modular Design

The rectangular shape of trough planters lends itself perfectly to modular design. Multiple units can be arranged in grids, staggered rows, or linear sequences to create patterns, winding paths, or expandable garden layouts. This allows designers to scale installations from small residential balconies to large commercial plazas with consistent, repeatable elements.

Uses of Trough Planters in Residential Design

Trough planters can be used to add structure, create division, and decorate residential design. Let’s take a look at some examples on how you can use trough planters in residential design.

Creating Division

Granite trough planters planted with ornamental plants were used as a border at the end of the terrace in Burwood Park in Walton-on-Thames, England. Granite is a durable material so it can withstand harsh weather conditions without sustaining damage. It may get dirty but just a quick polish and it’ll be good as new.

Privacy Screens with Style

Trough planters offer a unique blend of form and function, making them a versatile choice for a variety of outdoor spaces. Their elongated shape and clean lines lend themselves to a contemporary aesthetic, while their depth provides ample room for plant growth. Privacy screens with style can be achieved by using tall, narrow trough planters filled with ornamental grasses, bamboo, or climbing vines on trellises. This creates living walls that define spaces without permanent construction.
