Golf Rough Other Maintenance Practices
The use of fertilisers or irrigation on the semi-rough would not usually be carried out, except maybe in the most highly manicured and rare situations, however, there should be little need to carry out these activities on any areas of rough.
Drag brushing might be considered in helping to stripe a semi-rough, especially when mowing is not required or suitable, although for some greenkeepers and golfers, but not others, this might be taking manicuring of a course too far.
