Assessing a Garden Shrub for Bonsai

dsc_0420

At about this time of the year I usually start lifting material from the garden and assessing how suitable it is for use as future bonsai.  I am fortunate enough to have a reasonably large garden with lots of established and mature shrubs, some over thirty years old.  One or two species have been worth considering and are being developed as future bonsai material.

The photo above shows a variety of cotoneaster that self seeded in the flower bed before my arrival at the property.  I’ve been trimming the top growth each year but nothing else. I’m clearing the bed to make way for bonsai/vegetables so this shrub was being lifted anyway.

The leaves are a bit large but an attractive shape and colour. I thought I would lift it and have a look at the trunk line and any surface roots.dsc_0416dsc_0417dsc_0418

My conclusion? Put it somewhere else in the garden!  The surface roots are one sided and a bit lacking, the lower trunk curves and is then very straight with little taper.  Pretty unappealing and very little worth keeping as a future bonsai.  Still a nice garden shrub though so it went in a gap in a new flower bed out the front.

Mame cotoneaster 3 year progression

1 aug 11 mum cotoneaster

The above seedling was given to me in 2011 by my mother as something that I could put into the garden at some point but at that point I had very little in the way of bonsai material so I decided that I would try and grow it as  a very small tree.  I left it to grow for a couple of years and fed it heavily with chicken manure and a liquid feed.

The autumn of 2013 provided some great red foliage before it dropped and I decided to repot it the following spring.  The next photo shows it in a small mica training pot with free draining soil.  A lot of the extended branches were cut back and one sacrifice branch left to thicken the bottom of the trunk.

The tree grew so well that I repotted and rootpruned the following spring to spread the nebari some more in order to thicken the base further.  The sacrifice branch was removed.  The roots show some promise but I’ am keeping them covered to encourage them to thicken as much as possible.  The same container was used for the tree.

This year, I have continued to feed it but not as heavily as I think the trunk is the right size.  I only pruned once back in spring.  So the time came now to make some decisions about styling.  This is the tree before my work this morning:

I reduced all of the long shoots and then cut back the primary branches as they were too long and straight.  This has created some good taper which I am happy with.  I felt the movement of the tree was to the right was I looked at it but the bottom branch extended the opposite way.  I removed it and tilted the pot to create a better image.  I don’t think I’ll repot next year – just concentrate on developing ramification on the newly tapered primary branches.  I’m hoping for some of that beautiful red colour again in a few months.

At present the tree is only 11cm tall and I intend to keep it at this height.

Cotoneaster ready for styling

Today I got a few snaps showing the attractive berries on this Cotoneaster that I grew from a hardwood cutting a few years ago.  I’ve got a few of this species either growing in pots or the ground but this is the only one that displays red berries and I really like it at this time of the year.  Back in May it had some tiny white flowers so this is a future bonsai that I know I’ll enjoy looking at throughout the year.

I hope to give it a first styling soon, perhaps at a club night with a bit of advice from others.  There’s a couple of options that I can see: a cascade using the drooping branch at the back right, perhaps a slanting shohin using the thicker main trunk, maybe even being drastic and chopping most off to create an upright mame bonsai.  I’m open to suggestions 🙂

P.S. Can anyone confirm is this a Cotoneaster Microphylla?
