When does pre-emergent application typically open in Evansville, IN?

Pre-emergent application typically opens in April to May for Evansville, IN, when 2-inch soil temperature reaches the 50–55°F threshold for several consecutive days. Apply earlier than that and the herbicide degrades before crabgrass germinates; apply later and weeds have already sprouted. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What grass types grow best in Evansville, IN?

Evansville, IN is a transition zone where both cool-season and warm-season grasses are common. Cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue) thrive when 2-inch soil sits in the 50–65°F range and slow down in midsummer heat. Picking a grass family that matches the climate is the single biggest lawn-care decision; transition-zone homeowners often maintain blends and accept that neither family will look perfect year-round. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

When is the first fall frost typically expected in Evansville, IN?

In Evansville, IN, the first fall frost typically arrives around November 10. Soil temperature continues to drop through October and November, which closes the fall fertilizer window for warm-season grasses and opens the dormant-seeding window for cool-season grasses. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

How often is this schedule updated?

Recommendations recompute every 6 hours from the latest reading at Princeton #1, about 64 miles from Evansville. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What soil temperature do cool-season grasses need to germinate?

Cool-season grasses like fescue, Kentucky bluegrass, and perennial ryegrass germinate best when 2-inch soil temperature sits in the 50–65°F range for several consecutive days. Above that, summer heat stresses young seedlings; below that, germination slows or stalls. The re-entry interval (REI) on any post-emergent products you apply during establishment is on the product label; respect it before letting pets or children back on treated areas. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

Where does the soil temperature data for Evansville come from?

Soil temperature for Evansville comes from Princeton #1, a station in the USDA Soil Climate Analysis Network (SCAN) located about 64 miles away. Daily readings at depths from 2 inches down to 40 inches feed the schedule's window-open and window-closing decisions. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.
