PlantPerlite.
A lightweight, heat-expanded volcanic material used in horticultural growing media.
What it means for your plants
Particle size and the proportion used influence the final blend. Moisten dusty material carefully before handling and avoid inhaling dust. Perlite changes physical properties; it is not a complete fertilizer.
IN PRACTICE
Perlite may be useful when you want to adjust a blend without adding much weight to a hanging planter.
Put it into practice
Compare perlite and pumice for indoor plants, including weight, water behavior, particle size, and how to choose an amendment.
