Tips for Terrarium Rock Hardscapes

When creating rock hardscapes in terrariums, pay particular attention to the following:

Overall composition and visual flow

Try to think of the entire design as a whole.

It’s fine to focus on details and specific areas, but remember to frequently step back and see how the entire thing looks.

Creating interest and depth.

Try making overhangs, crevices, cracks, and other unique features to:

  • draw the viewer in to the composition
  • introduce dramatic elements and lighting shifts
  • create planting areas

Realistic textures, patterns, and colors

There’s nothing wrong with being creative, but if your goal is to make a natural-looking design, then pay attention to how things look in nature.

You can emulate nature to some extent, while still making the design your own.

Size Variance

Vary the size of the rocks and sections of rocks. Use some large ones, some medium, and some small, to:

  • create a more natural appearance
  • improve visual flow
  • keep the viewer’s interest
  • provide texture contrast

Pro tip: If the type of rock you are using is relatively soft, you can carefully crush some of it with a hammer to get some tiny pieces and grains (See safety advice at the end of this article.) Then disperse that in between the main rocks and around the base to create a next-level naturalistic design.

Natural strata

In general, try to keep consistent angles across all layers and grains in the rocks, to:

  • Improve the visual flow of the composition
  • Make the hardscape look natural

Forethought about plant and moss placement

As you’re planning the entire hardscape, try to envision the plantings that you’ll make.

With regard to the plants, think about things such as:

  • Type of plants and their cultural requirements
  • Size of the plants
  • Growth habit
  • Texture and color

Important Safety Information

Always wear the proper safety equipment when crushing, breaking, cutting, and carving rocks.

Some recommended equipment:

  • full-face shield
  • dust mask
  • thick work gloves
  • long sleeves and pants

Also use the proper tools, work in an appropriate location, and be extremely careful.
