Perlite & Soil Aeration

Perlite creates permanent air pockets in soil, coco and potting mixes so roots get oxygen and excess water drains away.

Shop small bags for houseplants and seed starting, plus larger perlite and aeration amendments for beds and big containers.

How to Choose

  • Coarse grades improve drainage in containers.
  • Fine and medium grades fit seed-starting mixes.
  • Use 10-30 percent by volume to lighten heavy mixes.
  • Dampen dry perlite before mixing to reduce dust.

Common Questions

Perlite or vermiculite?

Perlite drains and aerates. Vermiculite holds more water and nutrients.

Does perlite break down?

No. It is inert and stays in the mix as an aeration amendment.
