pumice potting mix Propagation Grade Pumice

Our 1/8 - 1/64" pumice is ideal for seed starting mixes, or cutting propagation. Add 15%-30% to a peat/perlite based mix. We hand screen to remove all pumice over 1/8 inch. Includes fines.

If you want a mix with less fines, order our 1/8" - 1/64 inch pumice mix which is double screened to remove over 50% of the fines in this mix. 

If you want a mix with little or no fines, order our 1/8" - 1/64 inch pumice mix which is triple screened to remove over 90% of the fines in this mix. 

We hand-screen to remove rocks over 1/8 inch; this does not mean anything long and skinny cannot get through.

If you are concerned about the size and would like to order samples, you can do so for the cost of shipping. If you decide to order 6 gallons or more, the freight cost of the samples will be reimbursed.

 Our pumice is a natural volcanic product mined in the Southern Cascades Mountains of Oregon.  You get only clean pumice... no rocks, roots or other debris.
     
Known as the "rock that floats", pumice has many tiny gaps or air pockets.
Our pumice is hand packed and bagged with a reusable tie for easy storage after you have used part of the bag.  If your pumice dries before using, moisten it to keep dust from forming. Dust from any rock or potting soil product should not be inhaled and can be irritating for people with sensitive lungs.   

All prices include shipping.
