Four Step Fertilizing Program For Lawns

Kirkwood Material Recommended Maintenance Program For Cool Season Grasses.

A good turf maintenance program consists of multiple applications throughout the growing season. For a high quality turf stand, 2-5 lbs. of nitrogen (N) should be applied per year/per 1000 square feet. A soil test in the spring will give you the most accurate fertilization needs of your turf.

Early Spring: March 15

Avoid heavy applications of N in the spring. About 1/3 of the 2-5 lbs of nitrogen for the entire year should be applied in the spring. Once soil temperatures reach 55 degrees for at least 3 consecutive days pre-emergent should be applied, as a general rule this is approximately March 15th, or when the forsythia shrub begins to bloom.

Fall is the most important season for fertilization. It is essential to promote good turf health. Fall is also perfect time for aeration, topdressing and overseeding. All of this can be done in combination with each other. This is the time to apply the other 2/3 of your 2-5 lbs. of nitrogen (N). After aeration it is highly beneficial to top-dress with compost. After topdressing, overseed and rake the seed through the compost. Upon completions apply a starter fertilizer. Feeds roots that have been damaged from the summer heat and drought while adding a broad leaf pre-emergent for those fall weeds.
