Depending on the species, environmental conditions and the time of year, re-affixing displaced bark (bark or
patch grafting) can be successful if it is done within hours of removal and the tissues, both intact and
displaced, have not dried out. If successful, callus production can be very rapid and growing over can occur
within months. If the tissues dry or cannot be replaced other interventions such as bridge or approach grafting
may be contemplated, but they can affect the aesthetic value of the specimen
