application of an antiseptic, like Bor- 
deaux mixture, before the wax cover is 
put on, may also be useful to destroy 
fungus spores. Rapid growing deciduous 
species, if girdled or peeled in the earlier

If the tree has been completely girdled, or if it could not

saved by an expert or skilful grafter through the process 
of “bridging,” described as follows.
