NATURAL OREGON VOLCANIC PUMICE

Our pumice is mined in the Southern Cascade Mountains of Oregon. Often called the “rock that floats,” pumice contains tiny gaps and air pockets. Each batch is hand-screened and packed by our nursery.

PACKAGING AND STORAGE

• Hand-packed in bags with reusable ties.

• Reseal the bag for convenient storage after opening.

• If pumice dries before use, lightly moisten it to help prevent dust from forming.

PLEASE NOTE: Dust from rock and potting soil products should not be inhaled and may irritate sensitive lungs. Moisten dry pumice before handling to help limit dust.
