Pumice 1-7mm is a horticultural pumice for plants, soil mixes and potting blends where extra drainage and air space are needed. Its porous, gritty structure helps improve the physical texture of growing media without making the mix overly compact.

This pumice is suited to gardeners, indoor plant growers and hobby growers who want a practical amendment for free-draining potting mixes. It can be blended into soil or growing media to help create a lighter, more open structure for plants that prefer less waterlogged conditions.

Key benefits

• Helps improve drainage in potting mixes and garden blends
• Adds air space to support a more open growing medium
• Useful for custom soil mixes for indoor plants, succulents, cacti and container gardening
• 1-7mm particle size is versatile for mixing through many common potting media
• Mineral-based amendment that does not break down quickly like many organic materials

Best suited to

• Indoor plant potting mixes
• Succulent and cactus blends
• Container gardening where drainage is important
• Custom soil and substrate mixes
• Growers wanting a gritty amendment for improving media structure

How to use it

Mix pumice evenly through your chosen potting mix or growing media before planting. Use more pumice when you want a faster-draining, more open mix, and less when you only need a small improvement in structure.

For established potted plants, pumice can also be worked carefully into the top layer of the medium when refreshing a pot, taking care not to disturb roots more than necessary.

Choosing the right option

This product is a 1-7mm pumice, making it a general-purpose option for many plant and container setups. The finer pieces help blend through potting media, while the larger pieces add grit and air space.

Choose this size when you want a versatile pumice for plants rather than very large decorative stone or very fine powder.

Check before buying

• Check that the 1-7mm particle size suits your intended soil mix or container size.
• This is a soil and media amendment, not a complete potting mix on its own.
• Adjust your blend based on the plant type, pot size and how quickly your growing media dries out.
• If using with specialist plants, follow the mix ratio recommended for that plant group or growing style.

FAQs

What is pumice used for in plant mixes?

Pumice is commonly used to improve drainage, add grit and create more air space in potting mixes and growing media.

Is pumice the same as perlite?

No. Both are used to improve media structure, but pumice is a porous volcanic stone, while perlite is a lightweight expanded volcanic glass. The best choice depends on your mix and plant needs.

Can I use this pumice for succulents and cacti?

Yes, pumice is commonly used in succulent and cactus-style mixes where a more free-draining medium is desired.

Can I use pumice by itself?

Pumice is best treated as an amendment unless you are following a specific plant or hydro-style recipe that calls for it as a standalone medium.

Pumice 1-7mm is a useful choice for building a cleaner, grittier and better-draining plant mix. Use it when you want practical pumice for plants, containers and custom growing media without overcomplicating your setup.
