Most of the trident maples now have tiny pink buds where new leaves are emerging to show that spring has arrived at Shibui Bonsai.
I’ve repotted most of the deciduous trees that need doing this year so it is time to move on to the evergreens. Some growers now repot pines in autumn but I’m still doing most of mine at the traditional spring repot time.
Today it was time to get a few pines into their first bonsai pots.
This twin trunk Japanese Black Pine has been developing slowly over the past 15 years or so. It has an impressive nebari and some well placed branches and now it is time to start developing better ramification. I think the restricted space in the smaller pot should help control the new growth and help the process.
Black pine after root pruning
Among the roots lies a clue to the origins of this tree.
This is one of the pines mentioned in the previous post. Seedlings were threaded through a hole in stainless steel disks to see if pines could be developed in a similar way to the maples as outlined in previous posts. Pines do not root quite as well as maples and only 2 out of 5 survived the process but the experiment did prove that it can be done.
In this case I put 2 seedlings through the same hole. In the process of growing new roots they have fused into a single twin trunk tree.
the steel disc
I’ve selected a round drum pot which has adequate size for a developing tree but still a reasonable match to the tree.
Now we wait until December for the first round of candle pruning to start the process of developing branches with full ramification.
Here’s one way of starting a good lateral root system. It works particularly well with trident maples but I have also used it on Japanese maples successfully and it should work well with any species that layers easily. Continue reading
Spreading basal roots, known by the Japanese term ‘nebari’ is considered very important for maple bonsai. Surface roots are prominent features of old maples, pines and elms so these features are also valued in bonsai of these species.
Nebari should, ideally, spread evenly all around the base of the tree, showing enough to give the tree the air of age and stability. Continue reading
It is winter at Shibui Bonsai and time to dig the trees in the grow beds.
I’m now digging most deciduous trees every year. This will slightly reduce trunk thickening but that should be more than made up for in better nebari and better nebari seems to produce vastly improved basal flare, particularly on trident maples. Continue reading
The autumn colours are gone and winter is usually pretty drab in the bonsai garden unless you have flowering Japanese Quince. Also known as Chaenomeles, most of the garden varieties flower later in winter, before the leaves sprout but this variety, called ‘Chojubai’ has occasional flowers all year round and a more concentrated display right through winter.
The brilliant orange flowers are small which is an advantage for bonsai.
The trident maples in the garden at Shibui Bonsai produce huge quantities of seed each year. This results in lots of seedlings growing in the garden beds. We usually leave a few hundred to grow on for use as bonsai.
You can germinate your own seedlings under controlled conditions but I find it far easier to let nature do that for me and I just harvest the seedlings I need from our garden beds.
Today I used some to put a trident group together. It will take a few year for this group to develop into show quality bonsai but groups are one of the quickest ways to get good results from immature material. Continue reading
Leaf drop has been slow and erratic at Shibui Bonsai this year. Some of the maples still have leaves but many of the tridents are now bare. that gives the perfect opportunity to review ramification and make alterations. Continue reading
I was fortunate to get a place with Tony Tickel at this year’s Bonsai week workshops. Thanks to the National Bonsai and Penjing Collection of Australia for making these bonsai activities possible. I think everyone who attended took home a lot of new information and ideas.
I finally decided to take an old black pine. I’ve had a couple of these trees since they were small seedlings but because I did not understand pine maintenance techniques properly they both gradually grew long, bare branches with foliage only at the tips. The trunks are thick and have mature bark which is highly desirable in pines. This one also has a large, spreading root mass so I thought it was worth taking some time and effort to try to resurrect it for bonsai.
I have spent the last 7 years forcing the foliage closer to the trunk to make the trees more compact. Pruning stimulated a few back buds on bare wood which were then nurtured until strong enough to remove the longer branches. I also resorted to grafting and inarching to get growth on other branches that had refused to bud.
Here is the tree before the workshop.
Black pine before
You can see that there was plenty of branches and foliage to choose from. The tree was well fed and healthy to cope with a major restyle.
black pine nebari
After checking several options we decided to try to keep the current front because the nebari on this side is far better than the other side.
There were several options for trunk lines and we have used a fairly standard informal upright trunk line with some jin and shari.
The first branch had a really nice shape but was far too heavy for the remainder of the tree so it was removed leaving a short jin.
The apex of the tree leaned too far forward and was an awkward shape so it was also jinned. Because the old main trunk was so strong it had thickened the trunk in that area giving a slight reverse taper to the new trunk so a small area of shari surrounds the jin to reduce the visual weight and maintain better visual taper.
After the worshop
Spring should see this pine grow strongly. I’ll begin my pine maintenance schedule with this one now to try to maintain density and promote inner buds – Early summer candle pruning and needle plucking followed by autumn thinning and more needle plucking should produce more even energy distribution and promote shorter growth and smaller needles.
‘Shari’ is the Japanese term for dead wood along the trunk of a bonsai. Dead tips of branches are referred to as ‘jin’. Continue reading
The shimpaku junipers I dug from the grow beds last winter have finally decided they are going to survive the trauma and have plenty of new roots and good growth on top. Continue reading
