Learn how to attach moss and plants to terrarium hardscape using terrarium plant glue, with step-by-step tips to avoid common mistakes and keep your scape natural.

Quick answer

Use a cyanoacrylate-based terrarium plant glue to attach moss and plants directly to dry rock or wood. Apply small dots of glue, press the plant material firmly for a few seconds, and keep the area dry until the bond sets.

Why plant glue beats twine for moss and small plants

Twine and wire hold moss in place, but they often look bulky and can trap debris. Plant glue lets you place moss exactly where you want it, including crevices and vertical surfaces, for a cleaner, more natural look. It also works for small rhizome plants and cuttings that would otherwise float away.

When glue is the wrong choice

Glue is not ideal for plants with delicate roots or those that need to be replanted often. It also fails on wet surfaces, so if your terrarium is already misted or humid, dry the attachment point thoroughly before gluing. For large or heavy plants, use glue only as a temporary hold until roots establish.

Step-by-step: gluing moss and plants in a terrarium

Prepare the surface: Clean the rock or wood with a brush and let it dry completely. Glue will not bond to wet or dirty surfaces. Check that the surface is bone dry before applying glue.
Apply glue sparingly: Place small dots or a thin line of glue on the hardscape where you want the plant to sit. Avoid large blobs that can squeeze out and look messy. Less glue is more; excess can whiten and ruin the natural look.
Press and hold the plant: Gently press the moss or plant base onto the glue and hold for 10–20 seconds. Use tweezers for precise placement. Hold firmly but don't crush delicate stems or leaves.
Let it cure before misting: Keep the glued area dry for at least a few hours, following the glue instructions. Misting too soon weakens the bond. Wait until the glue has fully set before adding moisture.
Monitor and adjust: Check the attachment after a day. If any pieces loosen, re-glue with a fresh dot. Avoid over-handling. A second small application is better than a large initial blob.
