Mow season
Mid-April through late October
Pre-emergent crabgrass
Mid-March to mid-April — apply when soil temperatures reach 55°F or forsythia bushes start blooming
Aeration window
Early to mid-September — the optimal window when soil temperatures cool and roots resume active growth
Overseeding
Mid-September, immediately after aeration — perennial ryegrass germinates fastest, Kentucky bluegrass takes longer
Dormancy
November through March — turf goes brown and dormant under snow cover, resuming growth as soil temperatures climb above 50°F
Fertilization schedule
- 1.Early April: spring greenup feed, often combined with pre-emergent crabgrass control
- 2.Early June: slow-release nitrogen for steady summer growth
- 3.Early September: recovery feed plus root development before winter
- 4.Late October: winterizer with higher potassium for cold tolerance
Cool-season grasses thrive in spring and fall. Summer heat stress above 85°F requires raising mowing height to 3-4 inches and watering deeply but infrequently. Avoid fertilizing during heat waves.
Lawn Care Considerations in Highland Park
Northern lawns face white grubs in mid-summer (a mid-July preventative is standard) and snow mold in late winter where snow piles linger. Brown patch fungus appears during humid July-August heat spells. Many states including Minnesota, Wisconsin, and Michigan restrict phosphorus in non-establishment fertilizer to protect waterways. Kentucky bluegrass and tall fescue dominate the region because they tolerate cold winters and recover well in the cool spring and fall growing windows.
Mow frequency
Once a week from mid-April through October when grass is actively growing. Slow to bi-weekly during mid-summer heat stress and early spring/late fall.
Mow height
Tall fescue and Kentucky bluegrass: 3 to 4 inches. Raise to the high end (4 inches) during summer heat to shade roots. Lower (2.5 inches) for the final fall cut.
Water needs
1 to 1.5 inches per week during active growth, including rainfall. Deep, infrequent watering (2-3 times per week) beats daily shallow watering. Reduce during winter dormancy.
Irrigation
Irrigation is helpful but not required — natural rainfall typically covers most of the season. Established lawns survive 2-3 weeks of summer drought by going semi-dormant.
