How many fertilizer applications should be made each year for cool season turfgrasses and at what time during the growing season? Briefly explain the benefits associated with each fertilizer application
What will be an ideal response?
For cool season turfgrasses, fertilizer applications should be made four times per year.
The first application should be made in early spring to break dormancy, heal injuries,
and prevent the invasion of summer and annual weeds. The second application should
be made in the spring to help turf survive heat encountered later in the season. The
third application should be in late summer to stimulate new tillers and rhizomes for
the following year and also to help maintain a vigorous and green turf until the fall.
The fourth application should be made in the late fall to promote root growth until the
ground freezes and to aid in early spring greening.
