[apple-crop] Tree height v. row spacing

2011-03-28 Thread Con.Traas
Hello all, What everyone thus far has said is relevant. Jon's rule-of-thumb of 0.9 x distance from row centre to row centre is good, but not a complete answer. To get to the bottom of this very difficult question requires information like light intensity (the more intensity the better the canopy

If you are growing hi-density apples, then tree height should be no greater than between-row width. Slightly less (0.9) is even better. Jon 2011/3/25 Arthur Kelly kellyorcha...@gmail.com: What do you all think about required row spacing for various tree heights?  Should row width be 1.1, 1.3
