Creating Moss Walls & Planting Vertical Surfaces with Peat'Clay
Hands-on techniques for building habitats, hardscape structures, moss walls, water features, and living environments. Each guide focuses on practical methods, materials, and workshop-tested processes.
Peat'Clay is a moldable growing medium designed for attaching mosses and small plants onto surfaces that would otherwise be difficult to plant.
Instead of relying on fishing line, glue or deep substrate pockets, Peat'Clay allows you to create planting zones directly on walls, driftwood and hardscape.
Once prepared, it can be used to create moss walls, green steep slopes, attach moss to wood and establish plants in areas where traditional substrate simply cannot stay.

Preparing Peat'Clay
Place the Peat'Clay into a mixing container and gradually add water.
Mix until it forms a soft dough.
The clay should be moist enough to shape but firm enough to remain attached to a vertical surface.
If the mixture becomes overly wet, squeeze out excess water before use.
For best results, prepare only what you intend to use during the current build session.
Creating Vertical Moss Walls
One of the most common uses for Peat'Clay is creating a living moss wall.
Apply the clay directly onto the glass or background surface before attaching moss.
Break larger moss clumps into smaller sections and press them firmly into the clay using tweezers.
For larger walls, lay the terrarium on its back so the planting surface faces upward.
This prevents the moss from slipping while you work.
Once the wall is completed, leave the terrarium lying flat overnight before standing it upright again.
This simple step dramatically improves the success rate of larger moss wall installations.
Attaching Moss to Driftwood
Fishing line and thread have long been used to secure moss onto driftwood.
Peat'Clay offers another option.
Apply small patches directly onto the wood before pressing moss into place.
The clay acts as a planting medium while keeping the moss in position during establishment.
This technique works especially well on:
-
Tree trunks
-
Branches
-
Root systems
-
Fallen logs
As the moss grows, the clay gradually disappears beneath the vegetation.
Greening Steep Slopes
Steep terrain often presents a challenge because loose substrate gradually slides downward.
Peat'Clay allows planting zones to be created directly on these difficult surfaces.
Apply small amounts of clay to the slope and press moss or small creeping plants into place.
This works particularly well for:
-
Hillsides
-
Elevated terrain
-
Ravines
-
Mountain scenes
The result is vegetation that appears naturally established on the landscape rather than sitting on top of it.
Creating Vegetated Cliff Faces
Large rock walls can sometimes appear bare and artificial.
By applying small pockets of Peat'Clay into ledges, cracks and crevices, moss can be introduced selectively across the surface.
The objective is not to cover the entire wall.
Instead, focus on creating small planting zones where vegetation would naturally collect.
A few carefully placed patches often look more realistic than full coverage.
Building Moss Canopies
Peat'Clay can also be used above ground level.
Small amounts can be hidden among branching driftwood before attaching moss.
Over time, these moss patches develop into miniature canopies and tree crowns.
This technique is frequently used when creating rainforest-inspired terrariums or forest dioramas.
The moss appears suspended within the structure rather than growing only at ground level.
Planting Difficult Areas
Some locations simply cannot hold traditional substrate.
Examples include:
-
Vertical roots
-
Rock overhangs
-
Cliff edges
-
Deep cracks
-
Elevated planting points
Peat'Clay creates a stable planting zone in these otherwise inaccessible locations.
Once established, the plants often appear to emerge directly from the hardscape itself.
Common Mistakes
Adding Too Much Water
Excess water softens the clay and makes it more likely to slide from vertical surfaces.
Mix gradually and remove excess moisture when necessary.
Standing a Moss Wall Upright Too Early
For large moss walls, allow the installation to settle overnight before moving the terrarium.
Covering Every Surface
Leaving portions of wood, bark and rock exposed often creates a more natural appearance than covering every available area.
Workshop Tip
The most successful Peat'Clay applications are usually the ones you cannot see.
Use only enough clay to support the plant. As the moss grows, the clay gradually disappears beneath the vegetation, creating a more natural result over time.
Material Used: Peat'Clay
Peat'Clay is the planting medium used throughout this workshop to attach moss and small plants onto glass, driftwood, cliff faces and steep surfaces.
Mix with water until it forms a wet, workable paste. Apply a thin layer onto the desired surface and press moss directly into it.
