Red Lava Rock

Regular price $8.99

Lava Rock makes an excellent addition to bonsai soil substrate as it retains water but doesn't allow bonsai tree roots to grow into it. Lava rock is a solidified molten igneous rock that has flowed from volcanic eruptions.

Lava rock also makes an excellent top dressing and can also be used in a humidity tray.

Features of Red Lava Rock:

  • Provides excellent aeration which provides oxygen to the roots of the bonsai tree
  • Has water-retention properties which supplies moisture to your bonsai tree between each watering
  • Allows excess water to drain quickly from the pot which prevents water salt build up and root rot
  • Known to help with strong root regeneration, especially with newly collected trees
  • Substrate granules are approximately 1/4" with some variation

Purchase one bag of lava rock for $8.99 or purchase three bags for $24.99 and save $1 per bag.

Quantity per bag: 1.5 lbs is approximately 4 cups of red lava rock
