| 5291092 |
stubs |
|
Given the size of the branch and the amount of foliage present, this is likely to be a giant stub rather than a viable section of the plant. |
| 5291093 |
stubs |
|
Stubs provide not only an entry point for decay organisms but also a food source. Large stubs only serve to feed the fungi decaying the wood |

leaving stubs can provide a route of entry for decay fungi especially on large limbs. Note the orange-yellow fruiting bodies on the underside of the limb. |

weak branch union |
|
You may not be able to convince everyone of the merits of proper pruning. Many people learn too late. |
| 1408048 |
flush cut |
|
Applying dressings to improper cuts, such as the one on this mountain ash, is primarily cosmetic. Research shows that commonly used wound dressings do not stop decay. |
| 1408050 |
flush cut |
|
This same tree had been cut in many places. Harsh flush-cuts and heavy coats of dressing will indeed cause the tree, as well as the people and property around it, some real problems. |
| 1408041 |
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. |
| 1408042 |
decay |
|
Fluids oozing from almost-closed wounds indicated internal problems. This English oak is 4 feet in diameter. The callus collar is very large, as is the internal column of decayed wood. |

flush cut |
|
you will later see an obvious early warning sign of decay -- a dead spot at the base of the cut. |
| 1408039 |
flush cut |
|
Decay spreads rapidly from dead spots. No amount or type of wound dressing will help. |
| 1408040 |
flush cut |
|
The size of the callus is not related to the decay process but depends on how rapidly the tree grows after pruning. All too often, big callus rings belie the presence of decayed wood or hollows inside. |
