Vermiculite 4L is an essential component for every indoor plant lover’s “soil bar.” If you have plants that cannot tolerate drying out—such as ferns, fittonias, or tropical foliage plants—vermiculite is the solution you have been looking for. This natural mineral can absorb a vast amount of water and nutrients, releasing them gradually according to the plant’s needs.
The 4-liter package is the optimal size for the spring repotting season. By adding 25–30% vermiculite to your regular indoor plant soil, you make the substrate resilient and nutrient-rich. This helps prevent nutrients from leaching out during watering and reduces the need for frequent watering while keeping the soil structure airy.
Manual
- Vermiculite must be mixed with the soil in a ratio of 1:1.
- This improves the structure of the growing medium and increases water retention.
Which to choose: Perlite or Vermiculite?
-
Perlite: choose this if you need more air and fast drainage (e.g., cacti).
-
Vermiculite: choose this if you need more moisture and nutrient retention (e.g., seedlings and tropical plants).
