Weed Pressure on Warm Season Grasses
Preparing the field properly prior to planting is
critical in establishing warm season grasses.
Fields can be cut the first year mid-July at 810” to help curb weed competition. Herbicide
research is being conducted to establish
guidelines for grass production.
First year cool season weeds
often shade the warm season
grasses. Grasses are
establishing deep roots.
During the second year
grasses out compete the
weeds.
Switch grass 2nd year
Approximately 50% yield
Third year 100% yield
