Whether you’re short on floor space or simply want to bring more greenery indoors, going vertical is a smart, stylish, and budget-friendly solution. Building a DIY plant wall doesn’t require a huge investment, just a bit of planning, the right tools, and of course, a love for houseplants.
Inspired by a creative couple in Berlin, this guide walks you through how to design your own lush green wall at home—perfect for renters, small apartments, or anyone looking to add a bit of jungle magic to their walls.

🌿 Why Build a DIY Plant Wall? (Background & Motivation)
In small apartments, every inch of floor space matters—and for plant lovers, it can quickly run out. That was exactly the case for one Berlin couple living in a modest 53-square-meter flat. Both already had growing indoor jungles, and as their collections expanded, the plants began competing with furniture and daily living space.
The solution? Take advantage of vertical real estate.
Their apartment, typical of Berlin’s charming Altbau architecture, featured high ceilings and bare walls—ideal conditions for creating a vertical garden. Turning an empty wall into a lush plant wall allowed them to reclaim their floor space while showcasing their favorite tropical plants in a visually striking way.
But more than just a design fix, building a DIY plant wall became a deeply rewarding creative project—blending aesthetic design, horticultural know-how, and personal expression into a green masterpiece that transformed their living room into a peaceful indoor retreat.
🌱 Inspiration Behind the Plant Wall Design
Creating a plant wall isn’t just about stacking pots on a shelf—it’s about crafting a living, breathing piece of art. For this Berlin couple, their inspiration came from world-renowned French botanist and architect Patrick Blanc, the pioneer of vertical gardens. His large-scale installations on city buildings sparked the couple’s imagination and gave them the confidence to try it at home.
Of course, their version had to be scaled down for indoor living. So they adapted Blanc’s techniques to suit a small apartment and a DIY budget. The goal was to combine functionality with beauty—designing a plant wall that didn’t just survive but thrived indoors, using the space efficiently while keeping the plants healthy and happy.
This vision set the foundation for their project: a modern DIY plant wall that brought the lushness of a tropical garden indoors, without sacrificing space or style.
🌼 Choosing the Right Plants for Your Plant Wall
The success of a DIY plant wall starts with picking the right plants. For a vertical setup, not all houseplants will thrive. You’ll need to consider their growth habits, light needs, and humidity preferences before placing them on your wall.
This couple focused on tropical varieties that love warmth, moisture, and indirect light—ideal for indoor conditions. Their plant wall featured a stunning mix of:
- Monstera
- Philodendron
- Anthurium
- Alocasia
- Calathea
- Begonia
- Pothos
- Caladium
When building your own plant wall, ask yourself:
- Does the plant prefer high humidity or dry air?
- Is it a climber or a trailing species?
- Will it tolerate being moved to a vertical environment?
- How much light does it need—and will that spot on the wall meet its needs?
Understanding your plants’ natural habitats is key. Some grow in forest canopies, others on the floor. Use this info to group plants with similar needs and give them the right spot on your wall.
💡 Pro tip: Use trial and error. A plant wall is always evolving. Observe how your plants respond and adjust as needed.
🛠️ How to Build a DIY Plant Wall – Tools & Materials
Building a DIY plant wall might sound complicated, but with the right tools and a weekend of work, it’s completely doable—even on a budget. This couple began their build in spring, which gave their plants the best chance to adapt during the growing season.
🧰 Tools You’ll Need:
- Power drill
- Jigsaw
- Staple gun
- Measuring tape
- Level
🪵 Materials List:
- Black builder’s plastic sheet – Acts as a moisture barrier to protect your wall
- Corrugated plastic panels – Lightweight and sturdy, forms the backing structure
- PET felt (100% synthetic recycled) – The growing medium; breathable, durable, and odor-free
- Wood frame – To support the layers and structure
- Screws & mounting hardware – For safe wall attachment
The project began by stretching a waterproof plastic sheet across the wall to prevent moisture damage. Next came the corrugated plastic panels, which provided structure. The felt layer was attached over this—this is where your plants will actually root and grow.
Choosing PET felt is crucial. Unlike natural felt, it doesn’t rot or smell, and it’s made from recycled plastic bottles—eco-friendly and practical.
This base setup becomes your plant wall’s foundation—ready to support healthy plant life without damaging your home.
💧 Creating the Watering and Lighting System
One of the most impressive parts of this DIY plant wall is the self-contained watering system. Rather than hand-watering each plant, the couple built a closed-loop irrigation setup that keeps the wall moist without waste or hassle.
💦 Watering System Overview:
- Water tank – Holds the supply
- Pump – Sends water upward through two pipes
- Drip lines – Located at the top to slowly distribute water down the felt
- Capillary action – Draws moisture down through the PET felt
- Gutter system – Collects excess water and returns it to the tank
This cycle keeps the growing medium evenly moist and reduces the need for daily watering. It’s a game-changer if you’re growing moisture-loving tropical plants on a vertical surface.
💡 Grow Lights:
Since indoor walls don’t always get enough natural sunlight, they also installed DIY grow lights. These were placed strategically to mimic the sun’s natural path, ensuring all plants got their fair share of light—especially the higher and lower zones of the wall.
Together, the watering and lighting systems made the plant wall sustainable and low-maintenance—perfect for busy urban dwellers who still want lush greenery in their lives.
🌿 Adjusting and Thriving – The Living Wall in Progress
A plant wall isn’t a “set it and forget it” project—it’s a living system that changes with time. After installation, the Berlin couple discovered that their wall needed regular observation, fine-tuning, and some trial and error to keep the plants healthy and growing.
What They Learned:
- Light levels needed to be adjusted based on plant position. Some plants needed more exposure, while others preferred shade.
- Watering schedules were tweaked depending on the season and plant response.
- Fertilizing had to be balanced—too little and growth slowed, too much and it risked root burn.
- Plant placement was reshuffled over time to give each one the environment it liked best.
Over seven months, they watched their vertical garden flourish. Some plants outgrew their spots, while others took time to adapt. But through patience and observation, the wall became more than décor—it became a dynamic, evolving indoor ecosystem.
This experience also deepened their connection to their plants and transformed how they interacted with their home. Each morning started with a visual check-in and a cup of coffee surrounded by greenery—a routine rooted in calm and care.
