Bedding Down:
As the growing season closes, now is the time to build your winter betds, bed down your trees for the season, read, update documentation, research new techniques to try next season, and mix soil in preparation for spring repotting. Check on winter-beds for moisture through winter.

A Bonsai Educational Experience for All

The Boise Bonsai Society (BBS) is a group of dedicated bonsai enthusiasts from the greater Boise, Idaho area. Our goal is to educate both our members and the general public in the art form known as 'Bonsai' (pronounced 'bone-sigh'), the ancient Asian art of growing miniature trees in pots. Our club holds bonsai workshops, collecting trips, and annual shows throughout the year. All levels of ability are welcome!
