This year I de-budded half of my garry oaks, in December. By de-budding, I refer to the practice of removing the terminal bud from the branches of the tree.
Why? The horse chestnut has a very dominant apical bud. So much so that the horse chestnut will grow as a single branch for many years - with no branching at all. The solution to causing the tree to branch is to remove the apical but before or while the but is swelling. The secondary buds then burst forth bringing many branches in many direction, each of which with their own apical dominance.
The garry oak seeding is a slow growing, stringy tree. Removing the buds could promote branching, and more branches also means the tree puts on wight faster.
My de-budded garry oaks are developing about 5 to 7 branches per twig, up from 1 to 3. I think the technique will help.

Maples and Steer Manure
The manager of The Hillside Cannor Nurser told me that maples top dressed with steer manure are less likely to develop several maple blights. The most frequent maple blight averted is whatever causes twigs to blacken and die back.
I was thinking of screening some dried steer manure and replacing a portion of the bark in my soil mix with this. It may not be worth it, if I take proper care of my bonsai.
However, my garden stock could benefit from this - and it certainly wouldn't hurt them.

Maple Seedlings!
I usually pick up a handfull of seeds from a japanese maple I know that seeds regularly in fall, and I throw them into a 'soiled' flat to come up in springtime.
I happened to find that many seedlings come up under the tree the next spring. I collected many of these in a ziplock bag, with a wet paper towel in it, and transported these new trees home.
Well, it is ziplock bag time for the next month! I saw the first crop of seedlings break their shell on Feb 25.
I will wait another week for my first harvest.
1) I had better have time to pot them up fast!
2) I have to have soil too - something I am low on right now.
3) if I wait to long, the seedlings will lose growing time this year.
Let me elaborate on point 3. Seedlings (in general) grow only from the energy they have stored within them. They do not need any nutrients or anything from the environment. After the first quick burst the plants begin to utilize their environment to generate more energy and structures. If the seedling is disturbed during the first flush of growth, it will quickly recover and re-establish itself.
So damaging the maple seedlings roots by pulling it out of the ground, and then storing the plant in a plastic bag with 200 of its brethren for a couple hours while I finish my errands; won't harm the seedlings a bit - if I do it to the seedlings first couple of weeks of their life.

5 degrees or 15?
Some bonsai literature claims that tree roots don't grow when a tree is dormant. Trees go dormant when temperatures get below 15 degrees. Other bonsai literature claims tree roots grow until the temperature lowers to 5 degrees, and resumes at the same temperature in the spring.
Someone in the bonsai club suggested that it probably depends on the species. Therefore, this year I am keeping a list of which tree's roots are active at repotting time, and which are not.
On a related note, bonsai literature tends to assume that new root tips are sensitive to breakage, freezing, and chemical burn from fertilizers. But some other literature suggests that new roots, new root tips and roots in general are as hardy as they need to be. Hence cuttings, seedlings and newly repotted trees can all be fertilized normally.
Who Knows?

Last Years Willow Cuttings
I repotted last years willow cuttings today. The primary reason I did it was because I like to play with my trees. Next it was: one year old willow cutting have got to be as hard to kill as fresh willow cuttings - which are very hard to kill - so these ought to be tough and can take a February transplant.
The yearlings had plenty of roots. I chose the lowest, most radial roots and chopped the rest. I planted them in cut-down gallon pots; and put them close to the house so they don't catch any sudden frosts.
I would not do this with a bonsai-ed willow. Willows drop branches when stressed. Don't ask what stresses a willow, the list is too long. Dropping branches is, of course, very bad for a bonsai. Take the utmost care to baby willows.
But the yearling trees have no branches - so either the "one branch" will die, or nothing bad will happen because there are no branches. I have stated why I don't think the one branch theory will happen.

Learning Bonsai
Oddly, there is no specific "beginning" when learning bonsai. I learned about bonsai with wild collected trees, meaning I had to learn to shape the tops of trees first; I had a trunk already and knew how to keep it alive. Others start from seed, so they must learn about trunk growing first. Still others purchase ready made bonsai and need to learn pruning techniques before anything else.
Workshops ($50-$80) start participants off with a tree, so they do not teach selection principles. They cover identifying the bonsai within the raw material, and how to make the tree like that. They do not cover how to care for the tree horticulturally. Nor do they teach how to refine a tree with the passage of time.
Bonsai is learned gradually; through trial and error; reading books; conversing with people of experience; and looking at bonsai trees. The Joshua Roth New Talent Competition considers "new talent" those with less then 10 years experience.

Grow a bonsai from seed kit
Grow your own bonsai from seed kits are ridiculous. This is because they give the impression that you can actually obtain a bonsai from seed quickly. The book which comes with the kit is very vague, an introduction to bonsai only. Seedlings don't need to be repotted, trimmed or wired.
What one needs to know about growing bonsai from seed is how to a) care for a seedling and b) develop good stock.
a) seedlings in crummy peat pellets are prone to drying out, or being drowned. This is because of the peat - it is either bone dry, or saturated. It doesn't spend much time slightly moist, what plants like. I suggest potting soil because people know how to keep plants alive in potting soil, or sand/gravel because the is what the seedling would want.
b) nebari and trunk girth are what is important about stock. The seedling has to be root trained by planting it on top of a flat surface, so its roots spread. Good nebari results in a greater trunk girth then a tree with poor nebari. But trunk girth is also obtained by unrestricted growth. This is why a bonsai from seed is a long term project.
Small bonsai from seed - 5 yrs
normal sized bonsai from seed - 12 yrs
large bonsai from seed - 18 yrs
