The Soil Trusted by Bonsai Professionals
This is the same soil mix used for our most valuable bonsai—and it’s now available to you, ready to use right out of the bag. Our Premium Bonsai Soil is a high-performance, hand-mixed blend crafted with sifted Akadama from Japan, red lava rock, and pumice. Industry insiders refer to it as Boon Mix.

Shipping Non-Tree Items
All non-bonsai items such as bonsai pots and bonsai supplies are shipped within 48 hours of receiving payment. Most orders are shipped either the same day or the next day, depending on the time of day the order is received.
Important Guidelines:
** We cannot ship to a FPO, APO, P.O. Box or to locations in Alaska, Virgin Islands, Puerto Rico, Hawaii or anywhere internationally.
** All Bonsai are shipped direct from the nursery and may ship separately from other items purchased via the Bonsai Outlet.
** If extreme weather is expected, we may delay shipping your Bonsai tree to guarantee a healthy arrival; in such a case we will contact you. We are shipping living trees and must be conscious of the temperature conditions to the delivery address, as well as, while in transit. That said, we reserve the right to hold the tree(s) to guarantee a healthy delivery. We will Hold Your Tree Until It is Safe to Ship.
