OK, I have come up with what may be an interesting idea.
Let's say you have a beautiful Kru (or Mysore, or whatever) with pseudostem grown to about 8 feet. This one should fruit at about 14 feet, right? Unfortunately, your greenhouse only has 12 feet of height at the ridge. Obviously, you will have a problem growing to full size.
Now, here comes the crazy part: you whack off the pstem to about 4 feet high.
After recovering from your butchery, it starts pushing out new leaves from that level.
Shouldn't it fruit when it gets to about 9 or 10 feet now?
My thinking is, the plant knows how many sets of leaves it has grown, regardless of how many are there NOW, so in theory this could work.
OK, you seasoned experts. Tell me why this wouldn't work.
