Scoria – The Earthy Powerhouse for Perfect Drainage
Unleash the benefits of scoria, a naturally occurring volcanic rock known for its strength, structure, and superior drainage properties. Locally sourced and sustainably processed, our scoria is ready to mix into your growing medium or use on its own.
Why Choose Scoria?
Scoria is a rugged, porous rock that keeps your potting mix free-draining and well-aerated. Its rough surface and irregular shape create air pockets in the soil, helping oxygen reach plant roots while allowing excess water to flow through with ease - perfect for reducing the risk of waterlogging and root rot.
Though slightly heavier than pumice, scoria’s solid structure ensures it won’t break down or float to the surface during watering. It’s long-lasting, reusable, and an ideal choice for gardeners and plant enthusists a like wanting a no-fuss, premium soil/potting mix amendment that delivers results time after time.
Key Benefits
Improves Drainage & Aeration – Prevents soil/mix compaction, ensuring roots get the air they need.
Thermal Regulation – Naturally helps stabilise soil temperatures, especially during seasonal shifts.
Stays Put – Unlike perlite, scoria won’t float, ensuring consistent structure in every pot.
Long-Lasting & Reusable – Doesn’t decompose or break down, making it a sustainable and economical choice.
Fungal Resistance – Reduces the risk of root rot and mould thanks to its excellent drainage profile.
How Much Scoria Should You Use?
Tailor your soil/potting mix depending on your plant’s specific needs:
Indoor Plants: Add 10–20% scoria to your standard potting mix to improve drainage and structure.
Succulents & Cacti: Mix 40–60% scoria with your soil to mimic arid natural conditions.
Bonsai Use: Use scoria as part of a well-draining bonsai mix—typically 30–60% scoria blended with other components like akadama, pumice, or bark. Scoria provides strong structural support for delicate bonsai roots and enhances oxygen flow for fine root development.
Outdoor Use: Use as mulch or in raised beds to prevent compaction and maintain soil health.
Note: Scoria doesn’t contain nutrients, so remember to fertilise or pair with a quality nutrient blend like Grow.it. Plant Fuel or Optimiser Fuel.
Experience the volcanic magic of scoria—strong, sustainable, and essential for thriving roots.
