The severed branches (4 per tree, 10 trees per species per year) were 25 to 35 mm in diameter. Depending on species, {\textquoteleft}Shigo{\textquoteright}-cut wounds were 4 to 6 percent wider than the diameter of the branch; conventional-cut wounds were 32 to 51 percent wider. Wound calluses around conventional cuts grew much faster than calluses around {\textquoteleft}Shigo{\textquoteright} cuts (14.8 vs. 8.1 mm the first year, 17.8 vs. 12.6 mm the second year). After one growing season the amount of wood exposed on conventional and {\textquoteleft}Shigo{\textquoteright} branch wounds was approximately equal even though the conventional cuts were originally much larger. After the second growing season, more conventional cuts than {\textquoteleft}Shigo{\textquoteright} cuts were fully closed.}, issn = {1935-5297}, URL = {https://auf.isa-arbor.com/content/14/11/261}, eprint = {https://auf.isa-arbor.com/content/14/11/261.full.pdf}, journal = {Arboriculture \& Urban Forestry (AUF)} }
