Sol Amendments (2Qt) Pumice
Vendor: SOL SOILS
Item #82840036
Pumice (filtered 3/8" to 1/4" size) is
relatively lightweight volcanic rock used as
an amendment in all types of soil. Its porous
composition allows it to retain moisture
and nutrients during watering, and release
them slowly over time as the root system
requires. Think of these components as little
batteries for your plants!
