3/16” Pumice is a volcanic rock that gets its appearance from the simultaneous rapid cooling and depressurization process after being ejected out of a volcano. 3/16” Pumice contains small vesicles, which is what causes it to be so light in weight. These vesicles help to retain nutrients and moisture when used as a soil amendment. 3/16” Pumice will also help with drainage as it creates great pore space in soil. 3/16” Pumice has a neutral pH and will not decompose. It also does not attract fungi, nematodes, or insects. By adding as little as 10% of 3/16” Pumice to your soil, you will experience these advantages.

- Component of container mixes and soil-less mixes
- Amending soil, mix 10% of 3/16” Pumice with soil to start out with. Percentages vary depending on the type of gardening project (Plants, flowers, cactus, tree, etc.).
- In soil-less potting mixes, some plants respond differently to the same ratio. Try small trial batches to determine what mix is best for your plants.
- For further 3/16” Pumice ratio information on gardening, call your local nursery for assistance.
