Product Description

 Perlite

Sterile perlite, a material composed of super-heated volcanic glass, resembles pure white foam pellets. Perlite granules feature small cavities on their surface that trap and hold moisture, which helps retain moisture in an otherwise quick-drying potting mixture. Lightweight perlite also aerates soil because the lightweight pellets prevent the organic ingredients in the soil mix from compacting. Perlite has an alkaline pH between 7.0 and 7.5, which can cause fluoride burn on foliage plants that prefer more acidic conditions.

Vermiculite

Vermiculite comes from super-heated mica. It forms an expanded platelike structure that traps air, moisture and nutrients present in a potting soil mix. Like perlite, vermiculite is naturally sterile, so it won't harbor plant diseases. It comes in a variety of sizes, but the larger particles are commonly used in the garden because they add more aeration to the soil. The more neutral pH of vermiculite, which falls between 6.5 and 7.2, makes it a suitable choice for most plants.

 

Benefits and Disadvantages

Perlite and vermiculite both provide a useful component in homemade or purchased potting soil. Plants that require moist, nutrient-rich soil grow better in vermiculite mixes, while those that prefer dry or quick-draining soil are more likely to thrive in a perlite-based mix. In propagation, for example, seedlings thrive in vermiculite mixtures because the soil remains moist without becoming soggy, while holding onto the nutrients the young plant need to grow. Cuttings perform better in quick-draining perlite because they are less likely to become overly moist and succumb to rot before they root.

 

Horticultural use

Both Perlite and Vermiculite are used in the garden to prevent soil compaction, improve aeration and retain moisture. They’re also used in propagation of new plants and seed cultivations, as well as in indoor container growing, composting and on lawns. However, the way that each material retains water, and how much water is retained, makes each one suitable for different plants. Vermiculite is ideal for plants that prefer lots of water, such as forget-me-nots and some irises. Perlite would dry out too rapidly for water-loving plants. However, the amount of water vermiculite holds is not ideal for plants such as cacti or rhododendrons, which need a well-drained soil. The moisture retained by vermiculite would lead to root rots or plant death.
