  • Scrub trunks of elm, birch, and zelkova with diluted lime sulfur to remove fungus or mold.
  • Protect trees from afternoon sun.

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

15 February 2018 Meeting:
Topics discussed:
Repotting:
  • The top of the tree reflects the base; finer soil equals finer roots, which equals finer branching (or ramification).
  • Goal of good soil is to produce the right mixture of water & air.
  • In our climate, we use the 'Boon' mixture (named after a Master in California): 1/3 Akadama, pumice, & grit.
  • Repot a mature tree about every 5-7 years.
  • Use aluminum wire on deciduous trees.
  • Look at the flare at the base of the tree. Remove or reposition crossing roots.
  • Keep some of the original soil, as it contains very valuable 'Mycorrhizal fungi'.
  • Already fertilizing with 5-5-5 Dr. Earth fertilizer.
  • For deciduous trees, use 1 scoop Bone mix & 1 scoop Akadama. Lay down a thin layer of larger particles first, then use smaller particles above that and around roots.
  • When securing tree, you may need to use a chop-stick to borrow a hole for the wire. Pull, then twist wire when securing.
  • For top-dressing, use grated orchid moss, mixed with water, india ink, and some live yard moss. When dried, sprinkle over the top layer of soil. This top-dressing encourages moisture toward the surface, and encourages fine roots at the top layer.
6 December 2017 Annual Planning Meeting:
We had a very good Annual Planning Meeting this year, and our new 2018 Schedule of Events is now posted, as of 2017-12-09. 2018 should be full of great events, so please plan and look forward to more details as the year progresses.

16 November 2017 Holiday Dinner:
We had a great time at our annual holiday dinner this year! Lots of fun, gifts, food, and fantastic fellowship. Thanks to all of our officers for all your work putting this great event together again this year, and for making it so much fun for all!
  • Members, please don't forget to attend our next annual planning meeting, to help us make next year another exciting success!
19 October 2017 Meeting:
Topics discussed: Fall Colors:
  • We saw some beautiful fall-color specimens this meeting, shown by their owners. Thank you for sharing!
Fertilizing:
  • Use no-nitrogen fertilizers every 4 weeks this time of year.
20 July 2017 Meeting:
Topics discussed:
Fertilizing:
  • Rapeseed balls for Junipers and Firs.
  • Kelp meal - sprinkle on surface.
  • Use doubled up terracotta pots for cuttings.
Soil:
  • An inexpensive substitute for Akadama is 'Spill cleanup' or cheap cat litter.
  • Granite - a little more acidic.
Pots:
  • 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.
