Premium Horticultural Pumice

Horticultural Pumice is a naturally porous, lightweight volcanic amendment engineered to optimize root health, moisture balance, and drainage. Unlike organic additives or softer aggregates, it will not decompose, compact, or break down over time, providing permanent structural aeration to your substrate.

Key Benefits:

• Superior Aeration & Porosity: Increases air-filled porosity (AFP) throughout the root zone, preventing soil compaction and guarding against root rot.
• Internal Moisture Retention: Micro-pores absorb essential water and dissolved nutrients, buffering hydration while allowing surplus moisture to drain freely.
• Long-Lasting Structural Stability: Rigid volcanic matrix resists degradation, making it fully reusable across multiple potting cycles without slumping.
• Neutral & Clean: Chemically inert, screened, and washed to eliminate fine dust that can choke aeration channels.

Recommended Applications:

• Bonsai, Cacti & Succulents: Blend at 20%–50% by volume to create free-draining, gritty mixes.
• Aroids & Orchids: Mix with bark and coir chips to build coarse, open epiphytic blends.
• General Potting Media: Incorporate at 10%–25% to lighten dense container mixes and improve oxygen exchange.
