Presidents MessageIMG_3634

I hope everyone enjoyed Mike Pistello’s program last month dealing with the great outdoors and collecting tree material from it.  Especially the equipment necessary you want to load your back pack with and the after care necessary for a good survival rate.  Thanks so much Mike for all your insight you’ve acquired roaming the high mountains for good material, I only hope that one day I’ll take that same challenging opportunity.

Our program for this months meeting will be presented by Jonas Dupuich a former  apprentice from Japan and now starting his own full time bonsai business.  Jonas is a astute craftsman of bonsai, sharing his monthly bonsai knowledge with his well done blog you can follow called (Bonsai Tonight).  Our program Thursday will be centered around pines and their progressive development.  Pines are one of the trickiest of all the bonsai trees we may ever try developing, and Jonas over the years has had much success in propagating them through their many stages of development.  If you have had questions about developing your pine trees and have experienced many hurdles, Jonas is the man to help you get through it!  So I’m really excited for him to share this topic with us Thursday evening.

This passed Tuesday evening a group of us club members at the Quinlan Center got a chance to review and make decisions as to how our show room facility will be divided up for the various areas necessary.  And I must say everything is coming together quite nicely for us. This facility has just about everything we’ll need in order to put on one of the finest shows ever.  Plus parking will not be a premium issue as in passed years, plenty available right out in front of the building.  We are now only two months out from the shows opening, and there’s still much to be organized and things worked out.  Ray Stagner our facilities member will be gathering volunteers this month necessary to form the various work teams.  Time will be a major factor in setting up our show, and efficiency will be necessary to make it all happen by opening time. Don’t worry,  no one is going to be left out,  if you available and physically capable.  Many of us members have accomplished the various tasks we’ll be faced with so there will be plenty of direction and guidance with team leaders.

Larry White and George Shoptaw have completed our flyers and promotional materials as of this week and they will be available this Thursday evening at the meeting.  Now its up to everyone to do their part in circulating them to those we come in contact with threw out  our busy lives.  Be creative and forward when presenting materials, you are going to be surprised how many positive responses you’ll receive!

The biggest priority facing everyone today is making sure that your on track with getting your show trees selected and ready. Juan Cruz in our September first meeting will be helping those in need with how to go about selecting your top soil, mossing, cleaning your pot and a oil you can use for a nice semi-shine.  Juan will cover all aspects of a show ready tree and the materials you’ll need to make it all happen.

As of last meeting we have been disturbing a sign-up sheet for those that will be having trees in our show this year.  There is still plenty of spots available for volunteers, including, Large Backdrop, Row Display, Shohin Display, and, Trees in Training.  I will be making the sign-up sheet available this Thursday evening so don’t leave until you’ve taken care of this opportunity.

Have a Great Month Everyone,

Jack Christiansen

J T’s Tree TipsJT Picture

It has been consistently hot this summer.  Thorough watering in the morning is best for your trees but check them in the afternoon on these ultra hot days.  Its not a good idea to water the foliage after dark as a moist condition on the leaves can lead to mildew in the warm summer evenings and it can damage later flowers and developing fruit.  But, you can still water the soil.  Rotate your trees.  Get them looking good from every direction.  The sun is getting slowly lower in its trajectory through the sky so it can really make a difference.

Our show is coming! our show is coming! October 1st our show is coming!!

We have an expanded venue so we will have more room to show our trees.  We would like to have all our members show a tree in the row display, backdrops or the trees in training.  Bring your trees i and we will help you work on them and get them show ready.  especially at the third Thursday or as time permits on the 1st Thursday.

Pinch, groom and keep working on your show trees so their ready when show time comes.  Any one who has a supply of sun moss, the kind that has a silvery look to it should be saving it for the show.  I have a few clumps of moss that I put in a flat container on top of carpet padding which I keep watered each day as I water my trees.  This really works to keep the moss growing and lush green.  Mine gets morning sun and afternoon shade.   Don’t let the moss dry out!.   Prepare your fine top dressings and start looking for accent plant material.

Deciduous tree Alert!!  Watch your wires.  The explosive growth we have had since spring is expanding the branches rapidly and the wires may be cutting in to the bark.  If so, unwrap the wire rather than just cutting it off.  If, in removing the tight wires, you cut into or expose any cambium tissue, dab it with a little tree seal so it won’t dry up and form a weak part of the branch.  When you later wire that branch with the weak part and try to bend it, it can break right there and you’ll be wondering why it happened.

Branches that you are developing from  scratch must be wired down and allowed to run and thicken to develop that first critical movement out from the trunk.  Let it run til the fall when you will cut back to start your next segment of the branch next year.  On your refined trees for the show you will notice that the growth usually slows down around now with the high temperatures.  If you have been pinching throughout the season you probably notice that it is not quite as quick to throw out vigorous new growth about now.  Let the growth elongate a little.  We will be having another growth spurt at the end of the month and cut back before the show and do some show wiring to dial the tree in.

Watch out for signs of insect and fungus damage. Bi-weekly spray a fungicide in the evening like Cleary’s 3336 wp or daconil ultra or Zerotol.   Honeydew, a shiny and sticky substance on leaves, is a sign of sucking insects in the aphid family.  They can’t digest all the sugar they get from the plant and deposit it on the foliage.  Many time ants, which love the honeydew, will cultivate the aphids, whitefly and scales, which produce it.  You also might see a dirty substance called sooty mold, which grows on the honeydew.  This readily washes off but the insects may not, so spray with Malathion® or Diazinon®, an oil like Ultra Fine® or Neep oil, or a systemic insecticide like Orthene® to control these problem insects.  Scales are resistant because of their hard shells, but this time of year we see young ones called crawlers moving out to new locations and, because they haven’t produced their protective shells, are susceptible to these sprays.  Apply any spray in the evening to minimize damage to your trees.

Look for splotchy or speckled foliage that might indicate spider mites.  Hold a piece of white paper under a branch and tap the foliage above it. Rub your finger over what ever is on the paper.  If it smears (Yuk!) you probably have spider mites.  Zap them with Diazinon® or Malathion®.  For chewing insects, the above or Sevin® work well.

Mildew and other fungi thrive in the warm moist crevices of the tree when we mist or over spray the foliage.  Daconil® is a good broad-spectrum fungicide that can be very effective on this problem.

Trees that are growing in the ground really benefit by having full exposure to the Sun.  Those in nursery containers need a little shade especially late in the day and those in bonsai pots need considerably more shade and, especially,  surface protection. I have been using a top layer of shredded sphagnum moss to keep the surface soil moist to promote surface roots and to insulate the root system from the Sun.  Also, try using shade cloth (30 – 40%) overhead to cut the Sun and a piece of shade cloth (65%) or insulating material on the soil surface to keep the roots and pot cooler.  Except for Bougainvillea, crepe myrtle, black pines, olives and peppers and the like, which seem to drink up the Sun, this will help your trees during this stressful time.  This will help them stay green and show their best.


Editor’s Note

Hi Folks,

For this month’s video I know we’ve all seen procumbens junipers before, but maybe not a yamadori procumbens.

 Notice about Set-up & Refreshment Duty

Hello Everyone, it’s Ray Stagner, in charge of facilities. For our club meetings to be successful, it is important our members participate and share in some of the responsibilities. We ask our members to help in the monthly duties of setting up and tearing down for both first and third Thursday meetings. Members who attend meetings regularly, are asked to help. Please arrive 1/2 hour before the meeting starts. I will be there to direct you. It’s very important, if you are unable to help on the days you are assigned to please contact me (408-209-5654). As well as helping with set up, we would like you to bring snacks of your choice to both meetings. If everyone participates, our meetings will start on time so we all can enjoy the activities planned for that evening.
