Pumice 1 to 4mm Premium Grade- - - [Bag 20ltr]

1-4mm Premium grade pumice. Pumice is a natural, unprocessed organic product.

The airy vocanic rock is ideal for use with cacti and succulents as well as other plants that require excellent drainage and air circulation. Plus, the porosity of pumice allows microbial life to thrive while maintaining soil structure and doesn’t decompose or compact over time like other soil amendments. Planting with pumice also has the advantage of a neutral pH along with a variety of trace materials.  Also used for propagation and Bonsai soil mixes.

There are many advantages to growing plants in pumice.

• reduces water runoff and fertilisation by increasing soil absorption in sandy soils. 
• absorbs excess moisture so roots don’t rot. 
• keeps clay soils loose over time for continued soil health.
