Zeolite 1–3mm 25kg

Zeolite 1–3mm is a natural mineral growing media supplied in a convenient 25kg bag. Its angular, porous granules help improve soil structure, increase aeration, retain moisture and nutrients, and provide long-lasting performance in horticultural, agricultural and landscaping applications.

With a high natural cation exchange capacity (CEC), Zeolite captures water and plant nutrients before gradually releasing them back into the root zone as plants require them. Its durable structure remains stable over time, making it a long-lasting soil amendment that does not readily break down or require regular replacement.

Best for

• Improving soil structure and aeration
• Potting mix and growing media blends
• Tree planting and seedling establishment
• Fruit, vegetable and ornamental crop production
• Turf, sports fields and golf courses
• Artificial turf infill
• Composting and vermiculture
• Soil remediation projects

Key features

• Natural mineral: Produced from naturally occurring clinoptilolite and mordenite zeolite.
• Water retention: Holds moisture within the root zone to help reduce watering frequency.
• Nutrient retention: Captures and gradually releases nutrients, helping minimise leaching losses.
• Root aeration: Angular blocky particles create air spaces that support healthy root development.
• Excellent stability: Highly durable mineral that resists weathering and remains effective for years.
• Neutral pH: Virtually no effect on soil pH, making it suitable for a wide range of growing applications.
• High purity: Over 99% crystalline zeolite for consistent performance.
• Environmentally friendly: Helps reduce nutrient run-off and supports beneficial soil microorganisms.
