The gravel can play an important role in your plant care:
A proper drainage layer is essential for maintaining a healthy and balanced environment in any terrarium. It sits at the bottom of the container and helps excess water flow away from the soil, preventing root rot and over-saturation.
Materials like gravel, LECA, or coarse sand are commonly used to create this layer. Without good drainage, stagnant water can build up, leading to mould, bacteria, and unhealthy plant conditions. Including a drainage layer is a simple but vital step in promoting long-term plant health and stability.
Sphagnum moss plays a helpful role in creating an effective drainage layer in terrariums. It’s often placed above coarse materials like gravel or LECA to act as a barrier that prevents soil from seeping into the drainage layer, keeping the layers visually clean and functionally separate.
Because sphagnum moss is highly absorbent, it also helps regulate moisture by holding excess water and releasing it slowly as needed. This added layer of protection can reduce root rot and improve the overall health of your plants.
