  • Scrub trunks of elm, birch, and zelkova with diluted lime sulfur to remove fungus or mold.

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!

Meeting Murmurings

20 July 2017 Meeting:
Topics discussed:
  • Rapeseed balls for Junipers and Firs.
  • Kelp meal - sprinkle on surface.
  • Use doubled up terracotta pots for cuttings.
  • An inexpensive substitute for Akadama is 'Spill cleanup' or cheap cat litter.
  • Granite - a little more acidic.
  • Large, plastic pot alternatives can be found at Fred Meyer - they include one large drainage hole.
Wood Hardeners:
  • Can obtain from WoodCraft; use matt finish.
  • Bondo has a product that repairs dry rot.
Cut Wounds:
  • Vasoline can be used for cut-wound sealing, or petroleum jelly. Easy to put on the end of a chop-stick.

16 March 2017 Meeting:
Topics discussed: Fertilizing: Other topics discussed:
  • Best to wire in Summer and Fall; not in Spring.
  • Best time to repot evergreens is in June/July, after foliage is very strong; evergreen strength is in the foliage.
  • When pruning Maples, always seal wounds. Maple wounds dry out and die back very easily; they also allow for infection.
  • Demonstration on cleaning pots to prepare for display.
  • 'Bar Keepers Friend' cleaning product can help clean stubborn hard-water stains from pots, etc. - Walmart Bar Keepers Friend.
