- I have read several articles on pruning trees, and done some too.
- Some pointers I recall:
-
- 1. Good branches to cut are ones that that rub each other, the house, etc.
- Also broken and diseased branches.
-
- 2. When choosing among branches to take out, remember that narrow
- crotches are weaker, and may someday blow down on your house, etc.
- So if you are choosing between two branches, and one makes a V with the
- trunk, and another a U, cut the V.
-
- 3. "Topping" (trying to limit tree size by cutting off the
- top) is generally aesthetically disasterous.
-
- 4. If a branch is so big you need to saw it, first notch along the
- bottom, then complete the cut on top. This prevents a branch
- from breaking and ripping a long strip of bark with it.
-
- 5. When pruning apple trees, try to open up the center, so the
- sun shines down through it.
-
- 6. Cut as flush as possible, instead of leaving stumps, since it is
- harder for bark to heal over a stump.
-
- 7. "Wound" compounds for spreading on pruned areas are a waste of
- money (but I believe Wyman's says they are good for really big
- wounds--so there is some disagreement on this).
-
- 8. Any pruning is robbing a tree of nutrients and energy. So, if you
- are pruning a small tree in order to shape it, you may want to simple
- cut the tips off unwanted branches, to impede their growth, without
- removing them. The tree will still be shaped, but not all at once.
-
- 9. Despite what most books say, experiments at one university showed that
- you do NOT need to prune transplanted trees back by 1/3.
-
- 10. Don't overdo it.
-
- And be careful. I was trying to prune one tree with a rope saw. This
- is a long rope, with a chain-type saw in the middle, and a bag of shot
- on the end. You throw the bag over the branch and pull the rope back and
- forth to cut the branch. I was aiming for a really high branch, and
- really reared back and threw the bag hard. Unfortunately I was standing
- on the rope, to the bag went about two feet and rebounded right between
- my eyes. That really gets your attention.
