REPAIRING WOUNDS BRACING WEAKNESS : Page 95

Crotches forming a wide angle are always stronger than acute-angle or V crotches. Often the latter look strong because they appear to be reinforced by a roll of callus. But that roll was formed, on the outside only, after that crotch was cracked or actually sprung open some time ago by heavy pressure, as of wind or snow, applied to the member aloft. Unlike a metal joint mended by arc welding it is not "stronger than ever" after its healing, but highly prone to refracture in another big blow or snow. It is particularly important to inspect trees near architecture or over driveways for V crotches, callused or otherwise, for they are inherently weak and hazardous. In trees small enough to handle himself, the home owner can reinforce a faulty
