After recent discussions I've had with Jow and the resuraction of the thread How to grow good bonsai stock like the Japanese nurseries, Shibui posted that he had some Maple seedlings for sale so I purchased some:
They arrived very healthy in brown paper packages tied up with string
My plan is to grow them all on but eventually only select the best few to keep and pass the rest on to others.
To give them the best start possible, I have followed Koji Hirimatsu's advice that he gave me at the recent Adelaide AABC convention about growing high quality shohin material:
• I worked the roots right from the start to achieve an even, radial spread.
• I've wired all trunks with exaggerated movement starting right from the base, ensuring no straight sections. I've made the bends forwards and backwards as well as side to side.
• I'll now let the trunks and branches grow freely after the wired sections to create the energy to fatten the trunks and branches.
• Any low branches will be encouraged to grow freely and uninhibited to act as sacrifice branches.
During my early days of bonsai my first teacher, Ron Flack taught me his 'Holey Ron' method of using a tourniquet to generate new roots. I couldn't find any washers the right size so I had to get creative
Some of the others I'm going to grow into groups so I used some sheet aluminium instead of washers.
In a weeks time I'll tweak the bends to compress and exaggerate them further. After that it will be full sun and hopefully they will be off to a good start at becoming future bonsai.
and I think I'll be doing the same thing with some of mine! Now to find some "legally aquired" aluminium sheeting...
