The Beauty and Benefits of Vertical Gardens
Vertical gardens have experienced a surge in popularity in recent years, and for good reason. These space-saving green installations offer numerous benefits and aesthetics that make them an ideal solution for urban dwellers. Some advantages of vertical gardening include:
- Space efficiency: Vertical gardens maximise limited space by growing plants in a compact, vertical arrangement, making them perfect for small balconies, patios, or walls with limited usable space.
- Air purification: Plants in vertical gardens effectively filter the air, removing harmful pollutants and toxins while releasing oxygen to create a cleaner, healthier living environment.
- Thermal regulation: Green walls can help insulate buildings from heat in summer and cold in winter, reducing energy costs and creating a more comfortable living space.
- Aesthetic enhancement: Vertical gardens can transform boring, drab walls into living canvases, adding a burst of colour and life to your personal oasis.
Planning and Designing Your Vertical Garden
The success of your vertical garden depends on careful planning and design. By considering your space, resources, and personal preferences, you can create a functional and beautiful vertical garden. Follow these essential steps:
- Determine your garden's location: Choose a suitable wall or vertical surface in your living area. Be mindful of available sunlight, exposure to environmental factors, and accessibility for maintenance.
- Select a garden structure: Design or select a prefabricated structure that accommodates your plant preferences and available space. This can range from modular planter systems to repurposed pallets or wall-mounted containers.
- Choose a suitable watering system: Vertical gardens may require a tailored irrigation system to efficiently provide moisture. Consider integrating drip irrigation or self-watering containers for consistent watering without wastage.
- Incorporate garden design elements: Choose complementary colours, textures, and foliage types to create a visually appealing garden. Experiment with dynamic plant arrangements and artful compositions to enhance your vertical space.
Choosing a vertical garden system
The structure you choose sets your budget, your watering routine and how much weight the wall has to carry, so decide this before you choose a single plant.
Felt pockets and pouches
The cheapest and lightest option, and the easiest to hang on a rendered or brick wall. Pockets hold very little growing medium, so they dry out fast and suit small, shallow-rooted plants such as herbs, succulents and trailing foliage. Expect to water often in summer unless you add drip irrigation.
Modular panels
Rigid plastic or metal cells that clip together into a grid, usually with a built-in drainage channel and often plumbed for drip lines. They hold more mix than pockets, so plants last longer and look fuller, and you can swap a single failed cell without dismantling the wall. They are heavier and cost more, and a waterproof membrane behind them is essential on any wall you care about.
Trellis and climbing supports
The lowest maintenance approach by a wide margin. A few climbers planted in the ground or in large pots at the base, trained up a trellis or wire frame, will cover the same area as a living wall for a fraction of the cost and with a normal watering routine. Our guide to climbing fig care covers the classic choice for a flat green wall, and the climbers and groundcover range has the alternatives.
Freestanding frames and repurposed pallets
Best for renters and anyone who cannot drill. Plant pillars, ladder shelves and lined pallets carry pots rather than a soil mass, so they are simple to rearrange and simple to take with you. Check the weight-bearing capacity before you load a frame with wet potting mix.
Vertical Garden Plant Selection
Choosing the right plants is crucial to the health and aesthetic appeal of your vertical garden. Consider selecting a blend of plants that satisfy essential factors, such as climate suitability, water needs, and growth habits. Here are some ideas for your vertical garden plant selection:
- Tropical plants: Species like ferns, bromeliads, and philodendrons add lush foliage and exotic flair to vertical gardens while adapting well to dappled shade and humid environments.
- Succulents: With their low-water requirements and diverse forms, succulents such as echeverias, sedums, and crassulas are ideal for vertical gardening in sunny spaces.
- Herbs and edibles: Vertical gardens can be practical and productive too! Grow herbs like basil, parsley, and mint or smaller vegetables like lettuce, spinach, and cherry tomatoes.
- Natives: Australian native plants like kangaroo paw, small grevilleas, and dianellas can offer hardiness and visual interest while fostering a connection to native ecosystems.
Plants for a wall in low light
Most vertical gardens sit against a wall that only gets a few hours of direct sun, and that rules out a lot of the plants people picture. Ferns, philodendrons, peperomias and cast iron plant hold their colour in dim positions and tolerate the uneven watering that living walls tend to get. Our guide to ideal fern environments is worth reading before you fill a shaded wall, and the ferns for shady areas range covers the reliable performers.
Keeping the maintenance realistic
The single biggest cause of a failed living wall is choosing plants with different water needs and putting them on one irrigation line. Group by thirst, not by looks: succulents on the hot, sunny end, ferns and foliage on the shaded end, and nothing in between that needs daily attention. Vigorous growers such as ivy and mint will smother their neighbours within a season, so keep them out or give them their own panel.
Balancing the design
Read the wall as a composition rather than a plant list. Repeat two or three species across the whole panel to give it rhythm, use one bold-leaved plant as a focal point, and let trailing species spill from the top third so the frame disappears. Varying leaf shape and texture does more for a green wall than varying colour.
DIY Vertical Garden Projects
Embrace your creativity and resourcefulness through these engaging DIY projects for your vertical garden:
- Pallet garden: Reclaim and repurpose an old wooden pallet by attaching landscape fabric to the back and installing it vertically. Fill the gaps between the slats with potting mix and insert your plants for an eco-friendly, rustic vertical garden.
- Hanging pocket planters: Create a series of pocket planters using upcycled materials like plastic bottles or canvas shoe organisers. Attach your planters to a wall or fence, filling each pocket with soil and plants for an inexpensive, personalised installation.
- Ladder shelving: Utilise a repurposed ladder as a vertical display for potted plants. Arrange your pots along the ladder steps, maximising the vertical space and adding character to your outdoor area.
Maintenance and Care for Your Vertical Garden
Proper maintenance can ensure the longevity and vitality of your vertical garden. Adopt these fundamental care practices for a thriving green oasis:
- Watering: Vertical garden plants may require more frequent watering due to their shallow root systems and exposed soil. Monitor moisture levels and water plants as needed.
- Nutrient management: Your plants will need regular feeding to maintain their health. Apply liquid fertilisers or slow-release granules suited to your garden's specific plants.
- Pruning and grooming: Regularly trim excessive growth, remove dead leaves, and groom plants as needed, promoting vigorous growth and maintaining a clean, beautiful display.
- Pest and disease control: Keep an eye out for pests and diseases in your vertical garden and treat any issues with environmentally friendly methods.
Troubleshooting common problems
Living walls fail in predictable ways. Almost every problem traces back to light, water distribution or pests.
- Plants thinning at the bottom. Water runs down, so the lower rows are usually wetter and the top rows drier. Adjust emitter spacing, or put your thirstiest plants at the bottom and your toughest at the top.
- Pale, leggy growth. Not enough light. Move the sun-lovers to the brightest end of the panel or add a grow light for an indoor wall.
- Uneven wetting. Blocked emitters are the usual culprit. Run the system and watch it, rather than assuming it is working.
- Mealybug and scale. Dense, sheltered planting is ideal for sap-suckers. Inspect fortnightly and treat early with horticultural oil before it spreads across the panel.
- Staining on the wall behind. A sign the waterproof membrane has failed or was never installed. Fix it before the planting matures, not after.
A rooftop or balcony wall adds wind to the list of problems, which our guides to rooftop garden ideas and small space plants for balconies cover in more detail.
