Garry Oaks - a solution?

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.

No more pencils, no more books..

In the books they say that in winter one should spend lots of time studying bonsai. This is because the trees are dormant and therefore we do not work on many of them.

Well now it is spring and I have hit the point where I am ignoring my book studies. Buying soil, ordering seedlings, potting, wiring; and most of all enjoying!

My nicest maple is half leaf right now. The leaves are very odd, when half formed.

Snow After Repotting

My maples and larches have started to break their buds. As per bonsai literature, when this happens we repot the trees. However, Victoria's weather is so mild that the buds break before winter actually ends. Hence the "I've already repotted some things, yet it is time for the last sub-zero cold snap."
It is all about aftercare.
I bring my plants right up against the house, where the radiant temperatures of the house will keep the repotted plant a few degrees warmer then outside is in general. Others put their repotted plants in an unheated garage or shed. Still others have a greenhouse to leave the plants in. One could put their trees into a deep pit, where the ground will insulate them.
The only other solution is to wait until after the early March Victoria cold snap. Most of us know it is coming. And the trees whose buds have broken aren't going to be growing very fast when the temperatures are so low. So if the tree doesn't bud out too early, it is ok to wait.

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.

6 Cold Days

It has been 6 days with tempuratures from 2C to -4C, since I posted the picture of the Elm bud(last entry). The bud is fine! I expected it to be withered and dead, but the cold has done nothing to it, yet.

My List for Spring

I went to my garden and made a list of things I will need to do by the end of April. Of course, many tasks will be added and deleted from this list. But if I have no clear plan I may endanger my plants. I have to:
...make tree growing boxes, benches and tags.
...replant some trees. Some young trees need to be repotted to take advantage of their vigour. The older trees need to be repotted because the soil in the pots has broken down to a level which makes watering difficult.
...dig up some garden growing plants, and pot them.
...dig up some garden growing plants, place a tile under them and re-plant them.
...trim the garden growing plants - no bar branches; trim to promote low branching.
...wire trees!
...clean dead areas on trees - to heal over, or to apply new lime sulphur.
...take cuttings.
...do air layerings when the buds start to swell.
...cultivate mosses.
...purchase soil.

Cactus Bonsai


I transplanted my cactus into a bonsai pot today. I haven't done any bonsai things for a while and I needed to do something. I thought it may be OK to repot because it is not zero degrees inside the house, where the cactus lives, as it is outside.

The cactus is about 4 inches tall. I found it in a nursery and was attracted to its trunks. There are three of them, growing from an underground root. Honestly, the cactus's canopy is sub par. I put it in a square terracotta pot to signify dessert. I think the pot is good, it promotes mood and it has a squat appearance which seems to work with the plant.

I have no idea how to care for a cactus and to develop canopy and ramification, but I will do my best.

Pots and Spiders

It turns out I have more pots then I thought I had. I had to move them from one outdoor shelf to another and it took a long time! It seems I collect pots just as I collect trees for bonsai. The pots sometimes are used for bonsai, other times I just enjoy the empty pot.
Of course, when you have lots of pots outside, one must be careful to tidy them every so often. I found two large spider nests in my pot collection, as well as several spider egg sacks. It is possible the two live spiders were dangerous. The reclusive and widow spiders around here are dangerous. An upside down liter sized garden pot is about the perfect size and shape for these kinds of spiders; and they will also use smaller and larger spaces, like all of your other pots. Heck, just be careful!

Redwoods growing in Dec and Jan

Today my suspicions are confirmed. My giant redwood is growing right now. Some of the twigs have grown 3cm, other buds are very swollen. I know because I pinched everything back 2 weeks ago when I first noticed it. Now the back buds have swollen and the non-pinched areas are the 3cm branches.

Hardwood Cuttings

I took about 60 japanese maple cuttings. I bought a rather large Shojo maple, with red bark and leaves. The trunk is grafted, but it is very close to the soil line, and it has barked up so the green base color is masked. The root spread is marvellous and there is a good movement and taper to the trunk. However, I cut about 6 feet off the top. I cut the branches into 6 to 8 inch (15-20cm) sticks, keeping care to know which tip was the growing tip and which was the rooting tip. I soaked these in a bucket of water over lunch, about an hour. I coated the growing tips with rooting gel, which I allowed to dry on, sealing the cuts. Then I planted the cuttings in a bundle in a pail of lava rock, on about a 30 degree angle to facilitate drainage and bury the cuttings deeper.
1) Take cuttings now. In the dormant season the plant barely lives or dies. It will spend the cold season trying to survive the cuts made. The cuttings will undergo the same process, healing. If the cutting succeeds in healing its base cut by the warm season, then it will quickly throw out roots and survive to grow. If the hardwood cutting is taken in spring, the plant will heal through the spring growth and have trouble putting out enough roots to survive summer.
2) Though the species is grafted, I think the non-grafted cuttings will be healthy and vigorous. Grafting provides increased growth and improved hardiness. In Victoria, hardiness is not necessary. The increased growth primarily helps nurseries which sell product based on size. Speedy growth means more profit. The small amount of decreased vitality makes no difference to the bonsai artist. Also, it is not too serious a decrease.

A Way of Obtaining Bonsai

Today I found and collected a tree. Above ground it measures 2ft by 2ft.
You are right - now is not the time to replant. It will stress the tree unnecessarily.
But I didn't just repot the plant. I ripped it out of the ground and stuffed it in a plastic bag. Then I jammed it in my vehicle, and went to MacDonald's. After dinner, I knocked most of the soil off the root ball. Now I am going to leave it unpotted overnight, and do the dirty work tomorrow when it is light. Did I mention the tree has been mostly uprooted for almost three weeks prior, and was sitting in dry soil anyway? (I gave in and saved the poor sapling.)

I think the tree will be all right.
1) The tree is a boxwood. Boxwoods are quite hardy. Quite.
2) I am soaking the tree in water and B vitamins. The vitamin is supposed to increase water uptake, meaning the plant can rehydrate faster.
3) I will care for the plant. I will ensure it has proper food and watering. I will shelter it from the wind, yet give it sunlight. I will plant it in a soil which will nourish the roots.
4) I will not style it until it is healthy.
5) It is winter. In winter the tree is not very active. A dormant tree doesn't need much water, so the dry soil it was in wasn't a problem, nor is taking a long time to pot the plant.

Individual Bonsai Histories

Today I showed a friend the bonsai tree I have been working on for her. This is always a great experience. My friend and her family gushed about how lovely it was and how special they felt. I think the most exciting part was not the nice shape of the tree or the fabulous naturally sharied trunk. The most exciting part is the tree's history. I rescued this plant, species unknown, from the garden in front of my friend's workplace. It was planted on one side of a walkway but its partner on the other side had died. I plunked it in my garden as a plant-plant, but when I dug it up it clearly had a bonsai trunk. The plant budded back well, as well. My friend had since done wonderful things at that workplace and informed me that the plant and her started at that company at the same time - in the beginning, 12 years ago. I have had the plant for 5 years. I have been training it for 3 years and I have known I was going to give it to my friend for 2 years now. Today is the first time my friend saw it but she has known about it for about 6 months.
By the way, she gave me Christmas cookies.

Animals attack bonsai

There is some kind of animal. It comes into my yard at night and throws my small boxwood off the table to the ground. This has happened three times now.
The boxwood has not been potted from its old nursery soil to bonsai soil. What this means is that the roots of my boxwood are more or less fine because the nursery soil is compacted and holds the roots in place. If the plant were in bonsai soil, most of the soil would fall off the roots if the tree fell off the table. Then one would have the problem of replanting stress to deal with, in addition to the stress of being dropped. (breakage, moss loss, bending out of shape)
What am I going to do about it? I secured the plant to the pot more firmly with wire looped through the bottom holes and twisted tightly at the top, to aid the safekeeping of the roots. I hope the animal doesn't come back.

growing bonsai stock

I made some decisions today to wire or trim certain things. In particular, I need to pay more attention to the branching of my young larches, the branches are easy to see now the needles are all gone. There are too many branches on these trees. I need to think ahead to how big I want these trees to be. Then I need to thin out the branches to a final few branches which will be part of the complete bonsai. Those, and a sacrifice branch or three to thicken the tree trunk up faster.
