Year after year, I end up with more and more Japanese Quince cuttings that turned out to be seedlings. Originally I was thinking to start a forest planting, but these Quinces have leaves that are too big to look good in a forest planting. Waiting for them to thicken up is not really an alternative either, as I can have much better use of the bench space that these trees take up. I decided to tie them all together to make one big tree. All together I have 9 tree seedlings. You can see that the trees growing in the colanders (left of the picture) have a much finer root system than the one in the pot (right of the picture).
Just wrapping the trees together wouldn’t produce too big of a trunk, since these are all very thin trees. I’ve built a metal brace for them to wrap around.
If I were to do this again, I would wait for even more trees before doing the wrapping, so that I can wrap a bigger brace. I used some raffia to wrap the trees around the brace. I positioned all the roots to radiate out from the center of the trunk, to ensure they’ll eventually form a good nebari. I then proceeded to plant the tree into big colander with a very fine soil mix. Japanese Quinces grow very vigorously, by next year, this colander will be filled with roots.
