Pine Bark

What is it?

Pine bark is an organic material made from the bark of pine trees. It is commonly used in substrates to improve structure, aeration and moisture balance.

  • Improves substrate structure

  • Creates air spaces around roots

  • Can retain significant amounts of moisture

  • Can improve drainage when used in larger pieces

  • Helps prevent substrate compaction

  • Slowly decomposes over time

Pine bark behaves very differently depending on its particle size and age.

Small particles - hold more water and keep the substrate moist for longer.

Larger chunks - create more air space and improve drainage.

As pine bark slowly decomposes, its structure changes and it gradually loses some of its original properties.

💡Key point: Particle size and age strongly influence how pine bark behaves in a substrate.
