Zeolite 6-20mm (Cactus/Succulent/Bonsai)

Zeolite 6–20mm is a robust, all-natural soil amendment ideal for gardeners seeking serious aeration and nutrient efficiency in their growing mediums.

This coarse-grade mineral improves long-term soil structure, helps maintain moisture balance, and provides extended nutrient retention thanks to its high cation-exchange capacity.

This size range is especially suitable for larger containers, outdoor beds, or as a drainage-enhancing base layer for deep-rooted bonsai, succulents, or mature cacti. Unlike other organic aerators, zeolite doesn’t degrade, ensuring a stable growing environment for years to come.

Features

• 100% natural and long-lasting mineral amendment

• Coarse 6–20mm particles for enhanced aeration and structural support

• High cation-exchange capacity for nutrient retention and slow release

• Will not compact or break down in soil mixes

• Ideal for bonsai, cactus, succulents, and large plant containers

• Supports microbial life and improves root development

Why You Should Buy

Zeolite 6–20mm is perfect for growers who want a sustainable, powerful way to boost their soil’s aeration while also enhancing nutrient efficiency. Its ability to hold onto minerals and gradually release them to plants and microbes makes it especially effective in low-fertilizer or organic growing systems. The coarse grade ensures better drainage and airflow, minimizing the risk of root rot and compaction over time.

FAQs

What size plants is this best suited for?
This larger 6–20mm grade is ideal for large bonsai trees, established succulents and cacti, or any plant requiring deep root-zone aeration.

Is this safe for organic gardening?
Yes, zeolite is 100% natural and safe for use in organic and no-till gardening systems.

Does zeolite hold water or just improve drainage?
It does both—it retains moisture within its pores while maintaining excellent drainage and oxygen flow.

How much should I use?
Apply between 500g and 2kg per square meter of soil or adjust for your container size to meet aeration goals.

Can it replace perlite or pumice?
Absolutely. Zeolite is a more durable alternative that won’t break down or float to the top like traditional aerators.
