Lawn mowing in Janesville averages $35–$75 per visit for a standard residential lot, depending on lot size and terrain. Full-season mowing contracts (weekly or bi-weekly from May through October) are often discounted compared to per-visit pricing. Lawn fertilization programs run $200–$500 per year depending on the number of applications. Aeration and overseeding averages $100–$250 for a typical Janesville yard.

In Janesville, lawn care typically begins in mid-April to early May when soil temperatures reach 50°F and the grass resumes active growth. First-of-season tasks include raking out winter debris and dead grass, applying pre-emergent herbicide for crabgrass (timing is critical — before soil hits 55°F), and the first fertilization of the year. The first mow is usually needed by late April or early May depending on the year's weather.

A complete lawn care program from a Janesville lawn care company typically includes five to seven fertilizer applications timed through the season, pre-emergent and post-emergent weed control, grub prevention, fall overseeding (often paired with aeration), and winter lawn prep. Some companies bundle mowing and maintenance with their fertilization programs. Premium programs may include pest control, mosquito treatments, and irrigation winterization.

Yes — but in Wisconsin, anyone applying pesticides or herbicides commercially must hold a state-issued pesticide applicator license through the WDATCP. Ask any lawn care company in Rock County to confirm their applicators are licensed before agreeing to chemical treatments. Licensed companies follow label directions and understand local environmental rules around buffer zones near water, application timing, and product selection appropriate for Wisconsin lawns.

Janesville's climate (USDA Zone 5b) is best suited to cool-season grasses that thrive in Wisconsin's spring and fall but go semi-dormant in summer heat. Kentucky bluegrass, perennial ryegrass, and tall fescue are the most common choices for Rock County lawns. Kentucky bluegrass produces a dense, attractive turf but needs consistent water. Tall fescue is more drought-tolerant. Many Janesville lawns are a blend of all three for resilience. Avoid warm-season grasses — they will not survive Wisconsin winters.

Lawn aeration is highly recommended for most Janesville yards, especially those with compacted clay soil or heavy thatch. Fall aeration (late August through October) is the optimal time for Rock County lawns — it is paired with overseeding to thicken thin areas before winter dormancy. Spring aeration is also done, though fall is generally preferred for cool-season grasses. Core aeration (plugging) is far more effective than spike aeration and should be used for compacted soils.
