Root over Rock

Posted on 23-Feb-2025 by Neil Padbury

I’ve been growing and developing root over rock bonsai for many years and gradually developed some techniques that help me produce reliable results. Check out some of the Shibui Bonsai root over rock trees.

More recently I’ve been working to develop some really good smaller Root over Rock bonsai. Like other styles, shohin ROR are much more difficult to get right. Getting good trunk taper, good bends and branching in a smaller tree is challenging. Adding extra height with the rock makes shohin ROR even more difficult.

Shohin sized trident ROR. The pot is 15cm diameter

Most of the Root over Rock trees I grow are trident maples. That’s because they grow fast and the roots develop quickly so we end up with roots flowing over the rock much quicker than with other species. The same techniques can be used to develop ROR plantings with other species. Here are a couple of Shibui Bonsai pine ROR but I’ve also developed ficus and Chinese elm as root over rock bonsai. I’m still working on developing branch ramification on these pines so the branch pads still look distinctly hairy and unkempt.

I’ve already shown some of the smaller ROR I’m attempting to grow but bigger ROR is also possible. Just allow for the weight of the rock. The following tree does not look very big but weighs around 20 kg so is more difficult to move for pruning, repotting and other maintenance tasks. The assistants who were helping dig trees from the grow beds that year christened this one Root over Boulder as they struggled to lift the tree and rock out of the ground.

You can find this year’s Shibui Bonsai ROR trees available for sale on the ROR catalogue – Root over Rock

Root over Rock pre-bonsai can be costly to ship due to the weight. For those attending the AABC National Bonsai convention in Canberra in May we can bring selected root over rock trees with no delivery cost. Make sure you get your orders in well ahead to avoid disappointment.

I’ve been asked to present a demonstration of Shibui Bonsai methods for developing Root Over Rock bonsai at this year’s Bonsai By the Harbour in Sydney in June. That’s your chance to get all the tips and proven Shibui techniques. We’ll try to bring examples of ROR at all different stages of development to make that session a really practical how to session.

For any NSW growers who fancy skipping the 3-5 years of growing, Shibui Bonsai will have a sales table at Bonsai By the Harbour so you too can order ROR trees from the Root over Rock catalogue and cut out the delivery fees. Don’t let the Convention attendees get the best trees. Make sure you order well in advance. I’m happy to put a reserve on trees and hold them until delivery at BBTH in June.

2025 events

Posted on 19-Feb-2025 by Neil Padbury

Shibui Bonsai will be out and about a bit more than usual this year.

We have secured a trade space at the AABC National Convention in Canberra in May. Space for transporting stock is limited and this year we’ll have a new range of display stands on board. We’ll still try to include a good range of trees but convention delegates are welcome to check out the catalogues and ask to have specific trees included in the stock we bring. Also feel free to talk to Neil if there’s any special species you would like to get hold of.

We have also been invited to present a couple of demonstrations at Bonsai by the Harbour in Sydney in June. This will be our first trip up to the Harbour city so looking forward to meeting local bonsai fanatics there. I’ll be demonstrating Shibui Bonsai techniques to create and develop Root over Rock bonsai in one of the sessions. The other session will focus on techniques for accelerated trunk development: field growing, sacrifice branches and more.

We also have the opportunity to bring Shibui Bonsai stock for sale while we are at Bonsai by the Harbour. We’ll try to take a varied selection of sizes, shapes and species but you are welcome to check out the Shibui Bonsai catalogues and ask us to include specific trees that you’d like to get a closer look at. This is a once only chance to secure quality Shibui Bonsai trees without the delivery costs! Catalogue

Show stands are hard to find and invariably, the wrong size or style so I started making my own. This is the latest attempt at a novel shohin stand.

Turned out just a bit small. Only the smallest bonsai fit in the spaces.

Next step is to stain it a dark colour then seal with some timber coating.

Time to start on a couple more medium single stands while I consider how to overcome some of the problems I found with this construction.

2024-25 Catalogues

Posted on 6-Dec-2024 by Neil Padbury

My apologies for the late listing of new trees. There always seems to be something more pressing than formatting the new catalogues or loading them to the site.

I haven’t fully proof read the new catalogues but, if I keep procrastinating you’ll never see the new stock so I’m crossing fingers that most of the trees are included and that I’ve matched the correct descriptions to the right photos.

Already the prunus catalogue is out of date as someone purchased a large cherry and a Prunus ‘Elvins’ after I’d finished that list. Make sure you ask whether any tree is still available to avoid disappointment.

Please note that the catalogues only list larger and field grown stock. We also have a wide range of smaller starters – way too many to list individually. If smaller, less expensive trees is what you want you can email neil@shibuibonsai.com.au and let me know what species, what size or shape and your price range and I’ll try to find some options that might match your needs.

Advanced bonsai for sale

Posted on 28-Sep-2024 by Neil Padbury

My back is not getting any younger or stronger so it is becoming increasingly difficult to manage larger bonsai so I am reluctantly offering several older bonsai for sale.

This is an opportunity to obtain well developed, 30-40 year old bonsai.

Trident maple – informal upright, root over rock.

Grown from seed in the late 1980s. This trident maple is one of my early trials with root over rock. You can see that the rock is on the small side and the tree has grown so the roots have almost swallowed the rock. Branches are well ramified and few scars on the trunk. Priced at $2,500.

Ficus rubiginosa – informal upright.

Grown from seed in the early 1990s. This tree started out as 2 seedlings fused together to form a twin trunk bonsai. The trunks fused very well but, as the individual trunks continued to thicken, the fork between them moved higher and higher so it is now an informal upright bonsai with a very thick lower trunk and a large first branch. The cold climate here is not the best for ficus so ramification is not as extensive as the trident above but plenty of primary branches to continue building on. $2,500

Cedrus deodar – informal upright

Cedars grow slowly so it’s not surprising that this is one of my oldest bonsai. Obtained as a pencil thick seedling from Nell Saffin in the early 1980s and developed slowly in pots, this tree is a beautiful example of deodar bonsai. Cedars of this age and quality do not come up often. Priced at $3,500.

If you’d like to see more photos of any of these trees, please ask. I’m happy to take shots of different sides or any particular aspects of the trees that you’d like to see.

I don’t really want to consign trees of this size and quality to the tender care of the postal service so alternative arrangements will need to be made for delivery. Pick up by the buyer is preferred but other options may be available so, if you don’t think personal pick up is possible, please talk to me about other delivery options.

Prunus ‘Elvins’

Posted on 22-Sep-2024 by Neil Padbury

Flowering bonsai can look spectacular. Species that produce a massed flower display can be even more spectacular.

Prunus ‘Elvins’ originated in Victoria in the 1950s. It is believed to be a hybrid with Prunus cerasifera (cherry plum) as one of the parents which means it is quite hardy. Prunus ‘Elvins’ flowers in early Spring and produces spectacular masses of white flowers that turn pink as they age. Flowers are on the previous year’s growth so they stand out well.

I’ve been so impressed with the flowering display from Prunus ‘Elvins’ that I’ve been propagating it as cuttings so Shibui Bonsai has good stocks of both small starters and a few larger field grown trunks as shown in the photo above.

If you fancy having a bonsai with the capability to produce flowers like that you can email neil@shibuibonsai.com.au to discuss price and availability.

Grafting pines

Posted on 15-Sep-2024 by Neil Padbury

This year I have a few extra JBP seedlings so I have the opportunity to graft some Japanese white pine.

White pine seems to be really difficult to source here in Australia as we can’t import seed any more due to strict quarantine, local seed is rare and hard to find and pines are generally difficult to strike as cuttings. That leaves grafting as one of the few methods to propagate Japanese white pine, provided you have a white pine as a source of scions to graft with.

Fortunately I do have a couple of JWP grown from seed I obtained at the Hobart Botanic gardens some years ago.

Some readers may be aware that the bark of white pine is quite different from black pine bark. This means that grafted white pines often stand out with the smoother white pine bark on the trunk and branches but the thick, furrowed, dark bark of JBP on the lower trunk. The only way I know to reduce the visual impact of the different bark is to graft as low as possible so the darker JBP bark is hidden in the roots and nebari.

Here’s my guide to grafting pines

Select a suitable JBP seedling as the root stock. seedlings from around 5-10 mm thick are suitable.

Select a suitable white pine shoot as the scion and remove most of the needles, just leaving a few close to the terminal buds.

Use a very sharp, clean blade to cut a vertical incision into the stock. Note that I’m cutting as low as I can to ensure there will be minimal black pine bark as the tree matures.

Make 2 cuts at the base of the scion to form a wedge. The cut on one side is longer than the other.

Slide the base of the white pine scion into the cut in the stock. The longer cut is against the trunk of the stock. Successful grafts rely on close contact between cambium layers of stock and scion. Cambium is a very thin, actively growing layer between bark and wood. As the size of stock and scion is rarely equal the scion is placed to one side of the cut in the root stock so that bark of both stock and scion are level ON ONE SIDE. This placement should ensure that the cambium layers on that side are close enough to join as they heal.

Wrap the graft union with grafting tape to hold the scion in place, put some pressure on the cuts to keep them in close contact to aid healing. Tape also stop the graft from drying out.

Finally, because pines are evergreen I need to protect the scion from dehydration. There are a number of ways to achieve this but I find ziplock bags really effective and easy to apply. A few drops of water in the bag, slip it over the scion and zip up the seal to make a mini greenhouse over your grafted scion.

The new grafts then go back outside but sheltered from direct sun so as not to cook the scions in their little greenhouses.

I’ll try to remember to update as these grafts progress.

Spring Flowering Bonsai

Posted on 14-Sep-2024 by Neil Padbury

We can use quite a few flowering species to brighten the spring bonsai benches.

Crab apples are a traditional favourite bonsai as they are hardy and easy to keep as bonsai. It is also relatively easy to get them to flower. I’ve had this ‘floribunda’ cultivar for close on 40 years since one of my early mentors showed me how she grafted flowering shoots onto seedling root stocks to get an almost instant flowering bonsai.

Azaleas are another traditional bonsai species though I read recently that azaleas were only recognised as bonsai in Japan relatively recently. Before that they were regarded as just flowering pot plants. The majority of azaleas in Australia are from the ‘Indica’ hybrids. These flower relatively early in spring. Mine have started opening flowers in mid September. In Japan, ‘Satsuki’ azaleas are more popular. Satsukis flower later in spring and have some spectacularly coloured flowers. Check out Bonsai Art for the best range of Satsuki azalea varieties in Australia – https://bonsaiart.com.au/satsuki-azalea-stock-list/

Azaleas are relatively slow growing so it takes years for an azalea bonsai to develop a thick, impressive trunk. Most of my azalea bonsai have been dug from older gardens when the owners were renovating the garden bends or extending the house. Fortunately azaleas transplant very easily at any time of the year. here are a couple of my azalea bonsai.

The Prunus family is another large group of species which flower in spring and many adapt easily to bonsai.

Plums are hardy and easily sourced from many nurseries. Some plums have become environmental weeds and can be found growing on roadsides and farmland. Most feral plums have straight, vertical trunks but occasionally you can find a really good trunk to collect and convert to bonsai.

Flowering cherries are a traditional favourite too but not quite as easy to maintain – or to keep them flowering well as cherries suffer from a range of pests and diseases. I’ve been transplanting seedling cherries from our garden bends into pots for those who would like to tackle flowering cherry as bonsai.

Prunus mume is much less well known here in Australia. It is sometimes known as flowering Japanese apricot. Flowers open from mid winter and are very fragrant. Generally hard to find but Shibui Bonsai has smaller cutting grown Prunus mume in 11 cm pots from $20

Japanese flowering Quince – AKA Chaenomeles were once popular as hardy garden shrubs that flower in late winter before the leaves emerge. Look for them in older gardens. Flowers in white, red and pinks. Flowering quince are used as bonsai but rarely develop thick tree like trunks but they can put on an impressive flower show in that dreary late winter period. Shibui Bonsai has limited numbers of several different coloured flowering quince as well as the much rarer ‘Chojubai’ dwarf flowering quince with orange flowers.

RED PINE

Posted on 7-Sep-2024 by Neil Padbury

Repotting is almost finished for this spring. Today I looked at a Japanese Red Pine. It didn’t need repotting this year but really needed some shaping so I allocated some time to pruning and shaping. It’s still definitely a work in progress despite being quite old. I’m still not convinced that the smallest trunk is good design but it’s harder to put back than to cut off so it stays until I’ve come to a firm conclusion.

The hour or so I put in only got as far as removing some surplus branches and wiring the right trunk branches. There’s still plenty to do on this one – when I get some more spare time.

Unfortunately I don’t have any JRP for sale at this stage. Seed is extremely hard to get here in Australia. I have managed to strike a few cuttings but they get snapped up as soon as someone finds out I have them. I planted some trees in our paddock with the view to harvesting seed as they mature. They’ve both produced cones for the last 2 years but the few seeds in those cones have all been empty. Frustrating, but that’s sometimes what working with plants can do.

I do have plenty of Japanese Black Pines but only small seedlings and a couple of larger, field grown trees. That’s another hard to get species now, so they tend to sell quicker than I can grow them.

Spring 2024

Posted on 6-Sep-2024 by Neil Padbury

Spring seems to have come to Shibui Bonsai a bit earlier this year. This crab apple took centre stage at a BSV bonsai show in October about 25 or 30 years ago. Now it’s flowering in early September a full month earlier.

Spring provides those of us in cooler Australian climates with a reward after months of cold and bare trees as the deciduous species begin to waken and push new leaves. i find it interesting that the trees don’t all grow at the same time. These trident maples are all growing within a few metres of each other and receive almost identical care but are progressing at quite different rates.

The shohin sized bonsai are also waking. 3 trident maples and a crab apple.

Please note that none of the trees shown here are for sale. Many of them have taken me 30 years or more to develop. I’m happy to sell pre bonsai and starters but I don’t want to spend another 30 years replacing these ones.

For those who do want an advanced bonsai I have a few older trees that I no longer have space or time for. If you want a special tree contact neil@shibuibonsai.com.au
