Pumice
A porous mineral component that can add drainage, air space and durable structure to specialty media.
Perlite
A lightweight amendment used to increase pore space. Fine and coarse grades suit different applications.
Worm castings
A concentrated organic amendment used in gardens, containers and propagation mixes. It is not normally the primary structural component of a potting mix.
Compost
Adds organic matter and is a major component in many soil blends.
Fertilizer and mineral nutrients
These address plant nutrition rather than physical structure. Always follow current labels and crop requirements.
- Do not add drainage amendments without understanding the existing mix.
- Physical properties and fertility are different problems.
- Custom formulation is often more consistent than modifying every batch by hand.
