The Rocky Mountain Bonsai Society



The Rocky Mountain Bonsai Society (RMBS) is a plant society affiliated with the Denver Botanic Gardens. It was founded in 1975 with a lineage to the Denver Bonsai Club founded in 1945.   Please go to the website’s history tab for more information about the society’s unique past.

RMBS monthly meetings are typically on the first Tuesday of each month starting at 7:00 p.m. and held at the Denver Botanic Gardens’ Plant Society Building.  Non-Members are welcome at the monthly meetings.  Nine months of the year, members meet on the third Saturday of the month at various members’ homes / bonsai gardens.  Since 1973, RMBS has held a 3 day bonsai exhibition at the Denver Botanic Gardens to display some of its member’s best bonsai trees for the public’s enjoyment.

 * It is Rocky Mountain Bonsai Society's policy and practice not to collect native trees (Yamadori) without a permit from the U.S. Forest Service, The Bureau of Land Management or permission from a Land Owner.   

Saturday Workshop
Air Layering as a Bonsai Cultivation Technique
David McPeters
Saturday, June 25th, 9:00am - 3:00pm
Denver Botanic Gardens
Bill Hosokawa Bonsai Pavillion
1007 York Street, Denver, CO  80206
A more advanced technique to propagate Bonsai is air-layering.  The Japanese term is called "Toriki". The principal of layering is to force a tree or branch to form new roots at a certain point by interrupting the stream of nutrients from the existing root system. This means you can use air-layering for several purposes; reducing the length of a trunk, growing a better Nebari (root flare or surface roots) or selecting a branch to be grown as a separate tree.  There are two main techniques to air-layer a tree; the tourniquet method and the ring method.  David will walk us through both of them.  Please bring a tree you have been considering to air layer, along with your tools, plastic wrap, ties, knife and "courage to do this....".

The Public is Welcome to Observe this Bonsai Technique
