What Is a Living Wall and Why Build One
A living wall guide for the Philippines covers modular pocket systems that mount directly on walls to create a flat, lush green surface. This is different from a general vertical garden, which includes trellises, hanging planters, and freestanding structures. A living wall specifically refers to plants growing out of felt pockets or plastic modules attached flush against a wall with built-in irrigation.
Living walls are gaining popularity across Metro Manila in restaurants, offices, condo lobbies, and residential homes. They cool surrounding air by up to 5 degrees through evapotranspiration. They absorb noise, filter air pollutants, and transform bare concrete walls into natural art. The modular design lets you start small with a single panel and expand over time as your budget allows.

Option 1: Felt Pocket Panel System
Felt pocket panels are the cheapest and easiest way to build a living wall. They come as pre-sewn fabric sheets with individual planting pockets arranged in rows. Each panel hangs from a rail or screws directly into the wall.
Step-by-Step Installation
- Measure your wall area and plan your layout. Each standard felt panel covers about 50 cm x 100 cm with 12 to 18 pockets.
- Install a waterproof membrane behind where the panels will hang. Use thick plastic sheeting secured with adhesive or staples. This protects the wall from constant moisture.
- Mount a horizontal support rail at the top of each panel position. Use heavy-duty screws and wall plugs rated for the combined weight of wet soil and plants (approximately 15 to 25 kg per panel).
- Hang the felt panel on the support rail. Most panels have built-in grommets or hanging loops at the top.
- Fill each pocket with lightweight growing medium. Use a mix of 60% coco coir, 20% perlite, and 20% compost. Avoid heavy garden soil, as it retains too much water and makes the panel extremely heavy.
- Plant one seedling per pocket. Push roots gently into the growing medium and firm around the base.
- Install drip irrigation tubing along the top of the panel. Poke emitters into the top row of pockets. Water flows down through the felt to lower pockets by gravity.
- Water thoroughly after planting. Check that water reaches the bottom row. Adjust emitter positions if lower pockets stay dry.
Option 2: Modular Plastic System
Modular plastic systems use individual interlocking planter boxes that click together on a wall-mounted frame. They are more durable than felt and allow easy replacement of individual modules. They cost more upfront but last 5 to 10 years.
Step-by-Step Installation
- Install a waterproof backing on the wall surface. For concrete walls, apply waterproof paint or attach plastic sheeting.
- Mount the metal or plastic frame grid on the wall using concrete anchors or heavy-duty screws. Follow the manufacturer spacing for your specific module brand.
- Click or slide individual modules into the frame starting from the bottom row. Work upward one row at a time.
- Fill each module with growing medium. Most plastic modules have built-in water reservoirs at the bottom that hold excess water for the roots to absorb later.
- Plant seedlings into each module. Use 1 to 3 small plants per module depending on the mature size of each variety.
- Connect drip irrigation lines to the top row of modules. Many plastic systems have built-in channels that distribute water from the top down through each row.
- Test the irrigation system before leaving it unattended. Run water for 10 minutes and check every module for even distribution.
Irrigation for Living Walls
Living walls cannot survive without proper irrigation in the Philippine climate. The small pocket volumes dry out within hours during summer heat. Here are your options.
Drip Irrigation (Recommended)
Run 4mm drip tubing along the top of your living wall. Insert drip emitters at 15 to 20 cm intervals. Connect to a tap timer that waters automatically 2 to 3 times daily for 5 to 10 minutes each session. This is the most reliable method and prevents human error.
Recirculating System
For walls without direct tap access, use a recirculating pump system. Place a reservoir tank at the base of the wall. A small submersible pump pushes water up to the top through tubing. Water drains down through the pockets and collects back in the reservoir. Add liquid fertiliser to the reservoir for automatic feeding.
Manual Watering
For small living walls (under 1 square metre), you can water by hand with a watering can. Water from the top and let it trickle down. This works for beginners but becomes impractical as your wall grows. Missed watering sessions kill pocket plants quickly during Philippine summers.
Best Plants for Living Walls in the Philippines
Choose plants that thrive in shallow growing medium and high humidity. Here are the top performers for Philippine living walls.
Ferns
- Bird's nest fern creates dramatic rosettes and loves the consistent moisture of pocket systems.
- Maidenhair fern adds delicate texture but needs consistent moisture. Perfect for shaded walls.
- Boston fern produces trailing fronds that cascade beautifully down the wall surface.
Foliage Plants
- Pothos is nearly indestructible and trails gracefully between pockets. Works in sun or shade.
- Philodendron varieties with compact growth habits fill pockets with lush green leaves.
- Fittonia (nerve plant) adds colourful pink and white patterns in shaded areas. Loves high humidity.
- Aglaonema provides colour with low maintenance needs. Choose compact varieties for pocket systems.
Ground Covers (for Dense Coverage)
- Creeping fig covers the wall surface between pockets for a seamless green look.
- Baby tears fills gaps with a carpet-like texture in moist, shaded positions.
- Peperomia compact varieties stay small and thrive in the limited pocket space.

Care After Building Your Living Wall
- Monitor irrigation daily for the first month. Check that all pockets receive adequate water. Dry pockets kill plants within 1 to 2 days during Philippine summers.
- Fertilise every 2 weeks. Use diluted liquid fertiliser (quarter strength) through the irrigation system or by hand. Living wall pockets hold too little soil to store nutrients for long.
- Trim and shape monthly. Prevent aggressive growers like pothos from smothering slower neighbours. Cut back trailing plants that block light to lower rows.
- Replace dead plants promptly. Bare pockets in a living wall look obvious and the exposed growing medium dries out faster, affecting neighbouring plants.
- Check the waterproof backing every 3 months. Moisture damage to the wall behind your living wall causes expensive repair problems. Look for water stains or damp patches on surrounding surfaces.
- Flush the irrigation system monthly. Mineral buildup from Philippine tap water can clog drip emitters over time. Run clean water through the system and clear any blocked emitters.
- Refresh growing medium annually. Remove plants, replace compacted growing medium, and replant. Old coco coir breaks down and loses its water-holding capacity after 12 to 18 months.
Frequently Asked Questions
What is the difference between a living wall and a vertical garden?
A living wall is a specific type of vertical garden that uses modular pocket systems mounted directly on a wall surface. Plants grow out of felt pockets, plastic modules, or panel systems attached to the wall with a waterproof backing. A vertical garden is a broader term that includes any plants growing upward, such as trellises, hanging baskets, tiered planters, and freestanding structures. Living walls create a flat, lush green surface that looks like a natural tapestry. They require built-in irrigation systems because the pockets hold very little soil.
How much does a living wall cost in the Philippines?
A DIY felt pocket living wall costs P1,500 to P4,000 for a 1-square-metre section, including panels, plants, soil, and basic drip irrigation. Modular plastic systems cost more at P3,000 to P8,000 per square metre because the plastic modules are imported. Professional installation by a landscaping company runs P8,000 to P20,000 per square metre, including plants, irrigation, waterproofing, and maintenance setup. The ongoing cost is mainly water and monthly fertiliser, which adds about P200 to P500 per month for a small residential wall.
Can a living wall survive Philippine typhoons?
Living walls mounted on protected interior walls or covered outdoor areas survive typhoons with no damage. Exterior living walls on exposed building faces can sustain wind damage during strong typhoons (Signal 3 and above). The wind can rip felt pockets, dislodge plants, and tear lightweight panels from their mountings. To typhoon-proof your living wall, use heavy-duty mounting hardware rated for wind loads, choose rigid plastic modules over felt for exposed locations, and install a windbreak screen during typhoon season. Placing your living wall on a wall sheltered from prevailing winds reduces risk significantly.
