Ho Yoku American Pumice – Horticultural & Professional-Grade Bonsai Soil Aggregate

Premium American Pumice – Trusted by Professionals

This is the pumice we use at New England Bonsai Gardens for many of our most valuable trees—including imported Japanese White Pines. Locally mined and professionally sifted, Ho Yoku American Pumice delivers excellent drainage, aeration, and moisture regulation for bonsai, succulents, cacti, and other potted plants.

Why Choose American Pumice?

In recent years, we've transitioned many of our mixes to include more USA-sourced pumice. Why? Not only does it help reduce costs and support domestic production, but our local bonsai professionals actually prefer it for its durability, neutral color, and performance in our climate.

American Pumice vs. Japanese Hyuga Pumice

• American Pumice – Slightly lighter in weight and color. Excellent for everyday mixes, conifers, and white pines. More affordable without sacrificing quality.
• Japanese Hyuga Pumice – Denser and more angular. Excellent for specialty or competition trees. Imported and higher in cost due to rarity.

Both are excellent—your choice depends on your tree’s needs, watering style, and soil budget.
