Overseeding thin turf areas can be done at this time. However for thin turf, heavy fall fertilization is more effective and will produce better long-term results. If seeding at this time, use a rate of 2.5 pounds per thousand square feet.

This is a good time to begin inspecting plantings for potential pest problems. Make regular inspections at two-week intervals making notes of identified pest problems and suggested solutions. For control of over wintering insects and egg masses, the use of dormant-oils is effective. Horticulture-oils are just as effective, and in sensitive plants, less Phytotoxic. These newer oils are lighter and can be used late into the season. As with any pesticide, read and follow label directions.
