Q: I have a very large area of mondo grass I planted control erosion. It has not filled in very fast. Is there anything I can do to expedite growth?

A: As with lawn grass, regular fertilization will speed growth. However, don’t use the rates found on turf fertilizer bags. Instead, fertilize now with 8 lb. of Milorganite per 1000 sq. ft. of mondo grass. In April, spread 4 lb. of 10-10-10 per 1000 sq. ft. and repeat every six weeks. That should help the mondo grass pick up the pace.
