I guess with a fast growing grass and sandy soil, they could be usefull.
Imagine bentgrass on steroids Jon. Bermuda and St. Augustine grow on runners like bentgrass, but those runners are more dense than the stems of any goose grass or crabgrass you have ever seen. Warm season grasses like this can be installed in plugs or strips. Imagine six inch strips on 12 inch centers and having perfect turf in less than 4 months! Bed edging has the same challenges. Where in a climate like yours or even mine, a cultivated edge is cut once a year. Down south, they edge monthly or even more often.
