During the Sonoma County Home & Garden Show, Sonoma Fairgrounds, Santa Rosa, March 15, 16 and 17, 2019, Art Kopecky led a group of volunteer REBS members in setting up and displaying bonsai. Club information brochures and the annual REBS August bonsai show postcards were handed out to promote club membership and attendance at the annual show.
On February 26, 2019, Eric Schrader returned to conduct a demonstration for the REBS meeting. Eric worked on a Monterey Cypress, approximately 12 years old, grown from seed. Eric said he collected the Monterey Cypress seeds from the Presidio of San Francisco. He planted a number of the seeds. The Monterey Cypress (Cupressus macrocarpa) were planted by the US Army in the 1880s.
The Monterey Cypress is a very vigorous grower and quick to develop into a bonsai. The tree experiences year-round growth. The demonstration tree was planted for awhile in the ground to speed its growth.
Eric brought in another Monterey Cypress as a potted bonsai. It was a smaller version of the demonstration tree. In order to maintain its shape and compact foliage, Eric will pinch the terminal tips of any runners.
Eric described the natural growth pattern of the Monterey Cypress branches as growing upward and outwards from the trunk. He demonstrated wiring the branches upward and outward. The ends of the branches were laid out flat to form the usual pads.
Eric identified a front view and marked it with two pieces of chopsticks. The front view was selected based on the movement of the trunk. There was one side of the trunk without branches which did not serve well for the front.
He then proceeded to remove surface soil to reveal some of the flair in the trunk base. Some surface roots were removed as well. Eric started to wire the top branches. He did this versus starting to wire from the bottom as normal because he intended to wire the branches upward and outward.
Eric said the Monterey Cypress is vulnerable to scale and spider mites and so one must keep an eye out for these pests and treat accordingly. He also said the Monterey Cypress does not take heat (100-degree F and above) very well. San Francisco’s weather is normally ideal for the Monterey Cypress. However, the weather can spike upwards in the summer.
Eric cut with a small saw the trunk more than 50%. The length of the trunk was grown to enlarge the trunk base. After growing the size desired for the trunk base, the length was no longer needed. This is referred to eliminating the sacrifice branch or limb.
Eric discussed creating jin and shari (deadwood features) to demonstrate age and mask the cut wounds.
When questioned about the best time to work on Monterey Cypress, Eric replied he prefers July, August and September time frames.
Upon completion of the demonstration, Ivan Lukrich won the Monterey Cypress.
Procumbens Nana Juniper Demonstration by Jay McDonald
On January 22, 2019, Jay McDonald was the guest demonstrator for the monthly REBS meeting. Jay has been interested in bonsai for almost 20 years. He studied under the Sensei Kathy Shaner and various other bonsai masters. Jay’s personal collection of bonsai is remarkable at about 25 bonsai. He brought for show and tell several of his mature bonsai, Ume, Olive and Japanese Larch (see images).
Jay’s demonstration tree was a Procumbens nana juniper, about 30 years old. The juniper was purchased from Bob Shimon of Mendocino Coast Bonsai. The juniper was grown in southern California for bonsai and displayed a lot movement in the trunk. Jay worked on the tree before bringing it to the demonstration. He cleaned up the foliage and removed any large branches that were no in proportion to the tree and trunk. He also did some pre-wiring of the demonstration tree.
Jay emphasized proportion of branches to diameter of the trunk and other branches. You can’t have larger branches near the top with smaller branches below them. The larger branches would be out of proportion and need to be removed by cutting them off or by cutting them short and making jins (deadwood) out of them.
Deadwood on junipers is essential. Jay pointed out some branches he stripped the bark off of and made in to jins. In order to create age and interesting characteristics in junipers, Jay said deadwood features are important.
Wiring the whole tree. Jay said bonsai is wiring. Wiring the whole tree is also important to creating bonsai with age and movement of the branches. Jay made it clear that he desired the wiring of the whole tree, including the small twig like branches. Wiring is controlling the movement and flow of bonsai design. He highlighted the purpose of wiring as creating movement, taper and interest.
Fertilizer. Jay believes in fertilizing his bonsai and starting early around the end of January. He has used an assortment of fertilizer, including organic and chemical. He will used Miracle Gro on his bonsai to give them a boost in growth when trying to build his bonsai. He then will use organic fertilizer when his bonsai are more mature and slower growth is desirable.
In finishing the demonstration bonsai, Jay applied a generous amount of moss to the top soil. Jay said moss is the proper manner in which to display bonsai. The moss can be removed when not displaying the bonsai.
Upon completion of demonstration, a raffle of the Procumbens nana juniper was held and club member Paul Wycoff won the bonsai.
Demonstration by Ivan Lukrich
On November 27, 2018, REBS held their regular meeting and demonstration. Club Sensei Kathy Shaner was scheduled to be the demonstrator; however, Kathy’s plane was delayed in Alabama due to bad weather. Ivan Lukrich at the last moment filled in for Kathy with a demonstration on three Japanese maples (Acer palmatum).
Ivan described the three Japanese maples as grown from seed from the same parent tree, approximately 10 to 12 years old. All three J. maples were planted in a large, plastic nursery container. The leaves were displaying wonderful fall colors. Ivan started the demo by removing all the leaves. He said pruning the J. maples would take place after the leaves drop off or before new bud growth occurs. Bleeding can occur during pruning at times.
Ivan pruned the unwanted branches and deadwood first. He discussed branch development and internodes. It is most desirable to have short internodes for bonsai. Pruning will help in dividing branches for ramification and short internodes. Ivan used cut paste to seal the wounds on the cut branches.
Ivan led a discussion of pinching new growth. Pinching the new leaf growth is necessary to maintain a tight ramification of the branches. Pinching is constant during the growing season for J. maples. After the first leaf pair has unfolded, remove the soft little tip of the shoot between them.
J. maples enjoy full sun. However, summer heat can burn the leaves and so afternoon shade or shade cloth is necessary.
Joanne Lumsden purchased the winning raffle ticket for the demo J. maples.
