This is perhaps the other side of pruning - the results of not pruning. As Michael says, one gets only 50 chances. And I am a very slow learner. I have a number of trees, (of many different cultivars, so it isn't just a cultivar issue), on Ottawa-3 rootstock, (any relationship to my problem?), which I have been endeavouring to train in a central leader fashion. I do appreciate that I failed badly in my early training, and have ended up with my scaffold limbs a lot higher than they should be. But that is not my current problem. The leader on many of the trees persists in bending over into a graceful arc. And, no, this is not induced by the weight of fruit pulling it over - most of the affected trees are not yet bearing.

Herewith an example of what I am talking about: <a href="[www.flickr.com]; title="bent trees 004 by David Maxwell, on Flickr"><img src="[c4.staticflickr.com]; width="2048" height="1829" alt="bent trees 004"></a>

So, two questions: 1) why is this happening? 2) what do I do about it? (Go around and plant tall stakes at each tree to bind the leader vertical?)

Hello David,
Yes, I've seen the same on some of my O-3 trees, but not all. Could have something to do with the root, or at least with the root-scion combination. Some have started a new vertical leader from the bent part.
Now, since we are probably the only 2 in this community to have trees on this rootstock (it is not available in the US as far as I know), we are not likely to get many opinions on this rootstock...
