Pumice – Lightweight Volcanic Soil Amendment for Healthy Plants

Lightweight Pumice – Volcanic Soil Amendment for Superior Drainage & Moisture Retention

Pumice (filtered to 3/8″–1/4″) is a lightweight volcanic rock prized for its porous structure. When added to potting mixes or used as a top dressing, it enhances aeration, regulates moisture, and supports healthier root systems—perfect for cacti, succulents, bonsai, and all your favorite houseplants.

Key Features & Benefits

• Moisture Retention: Absorbs water and nutrients, then releases them gradually like tiny batteries, nourishing roots over time.
• Improved Drainage: Prevents waterlogging by allowing excess moisture to flow away quickly.
• Enhanced Aeration: Creates air pockets in soil for optimal oxygen flow and vigorous root development.
• Lightweight & Durable: Easy to handle, won’t compact or break down over time.
• Sustainable & Clean: Pre‑dried for convenience—no damp, dusty mess—and 100% natural, chemical‑free volcanic rock.

Why Use Pumice in Your Indoor Garden?

• Healthier Roots: Reduces risk of root rot with superior airflow and consistent moisture balance.
• Consistent Growth: Balances hydration levels to prevent stress from over‑ or under‑watering.
• Versatile Applications: Ideal for mixing into potting soil, top dressing, propagation medium, or bonsai substrates.

How to Incorporate Pumice

• Soil Amendment: Blend 10–30% pumice into your potting mix to improve structure and drainage.
• Top Dressing: Sprinkle 1–2 cm over soil surface to enhance evaporation control and deter pests.
• Propagation Medium: Use alone or combine with other substrates for rooting cuttings and seed starting.
