Last year, I came up with an ambitions idea of growing a large fused trunk Trident Maple, but I didn’t have the material to do the project, so, I started from scratch. In June 2010, I got the seeds from my bonsai teacher, put them in the fridge for a couple of weeks before sowing them in July. They germinated at the end of August (see the picture below).One lesson I learned from this exercise is not to sow the seeds too densely. You can see from the image above that although the seedlings look quite healthy, they were not as tall as I hoped them to be.
What I did with some of the seedlings this month to kick-start the trunk fusion is self-explanatory from the images below.
