Compartmentalization Of Decay In Trees (CODIT) |
|
These sections came from a maple tree that was wounded experimentally. A wide variety of decay resulted, but all wounds showed the same type of thick callus ring. Again, callus is associated with the growth rate of the tree, not with the decay process. |

crown reduction (pruning) |
|
When removing a leader, slant the cut gently as shown on the left' a flat cut invited rapid decay development. |

|
On the other hand, a severely slanted cut also encourages the spread of decay upward and downward. |

pruning (general) |
|
Every branch has a thick bark ridge separating it from the main stem. Never cut behind the branch bark ridge. Never leave a stub, as shown here. Always cut as close as possible to the outer edge fo the branch bark ridge, as indicated by the red line. |

pruning (general) |
|
The inner side of the sample shows the hard inner wood of the branch bark ridge. If you cut behind the ridge at the arrow you'll injure the main stem. Cut the branch, not the trunk, by following the red line. |

pruning (general) |
|
Never prune where this saw is poised, behind the bark ridge. Cut in front of the ridge, as indicated by the red line. Never prune when the leaves are forming. As mentioned earlier, don't paint wounds except for cosmetic reasons; then use a thin coat of a commercial dessing, never a house paint |
