When does pre-emergent application typically open in Paducah, KY?

Pre-emergent application typically opens in April to May for Paducah, KY, 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 Paducah, KY?

Paducah, KY 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 Paducah, KY?

In Paducah, KY, the first fall frost typically arrives around October 27. 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 46 miles from Paducah. 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 Paducah come from?

Soil temperature for Paducah comes from Princeton #1, a station in the USDA Soil Climate Analysis Network (SCAN) located about 46 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.

Disease

IN WINDOW

Azoxystrobin or propiconazole fungicide

Large patch fungicide for zoysia, St. Augustine and centipede

Large patch is a fungal disease of zoysia, St. Augustine and centipede that shows as tan or orange rings in fall and spring. The fungus starts its attack as soil cools in autumn, which is when a preventive fungicide goes down. Extension sources put cultural steps first: no fall nitrogen, early-morning watering only when needed, and better drainage.

Read the full guide →

Granules, for a spreader: Scotts DiseaseEx (azoxystrobin)
Liquid, zoysia only; needs pump sprayer: Select Source propiconazole 14.3

Shallow soil temperatures are in the action band at 61°F at the Princeton #1 sensor, 46 miles from your location.

Window: Sep 1 to Dec 31. Window typically open for 2 to 3 weeks.

Why this, why now

Dissent and uncertainty: NC State starts St. Augustine and centipede earlier, as soil falls to 80°F for five days; this window follows the 70°F figure NC State gives for zoysia and Clemson and Arkansas give for all three grasses. UGA (C1088) and Missouri (IPM1029) time the spray by thatch temperature (69.8°F; 70 to 75°F), not soil. The second application comes 3 weeks (Clemson), 4 to 5 weeks (Arkansas) or 4 to 6 weeks (NC State) after the first, while soil stays above 50°F.

Safety details (REI, air-temp ceiling, pre-rain)

Keep pets and children off treated areas for 12 hours after application.

Air temperatures above 90°F can volatilize the product or stress the lawn. Wait for cooler conditions.

Propiconazole fungicide

Spring dead spot fungicide for bermuda

Spring dead spot is a root disease of bermuda that shows as dead circles when the lawn greens up in spring. The fungus infects roots as soil cools in fall, so fall is the season a fungicide works; spring sprays do not. Extension sources put cultural steps first: no nitrogen after late summer, less thatch, and better drainage.

Granules, for a spreader: Andersons Prophesy propiconazole
Liquid, needs a pump sprayer: Select Source propiconazole 14.3

Shallow soil temperatures are in the action band at 61°F at the Princeton #1 sensor, 46 miles from your location.

Window: Sep 1 to Dec 31. Window typically open for 2 to 3 weeks.

Fall soil test

A soil test from your local extension lab measures pH, phosphorus, potassium, and organic matter for around $15-25. Doing it in fall gives you the data to plan winter lime applications and the next season's fertilizer rates without guessing.

Mail-in lab test: MySoil soil test kit

Shallow soil temperatures are in the action band at 61°F at the Princeton #1 sensor, 46 miles from your location.

Window: Sep 1 to Nov 30. Window typically open for 2 to 3 weeks.

Amendment

IN WINDOW

Fall lime application

Lime takes months to break down and adjust soil pH, so a fall application has time to work before next spring's growth. Lime belongs on soil whose test shows pH below the target range, because over-liming alkaline soil locks out nutrients.

Test first: MySoil soil test kit
Only if the test shows low pH: Jonathan Green Mag-I-Cal Plus

Shallow soil temperatures are above the 60°F trigger at 61°F at the Princeton #1 sensor, 46 miles from your location; the season is cooling toward the band, so the work can start now.

Window: Oct 1 to Nov 30. Window typically open for 2 to 3 weeks.

Fertilizer

WATCH

Cool-season fall nitrogen

Fall is the most important feeding of the year for Kentucky bluegrass, tall fescue, and ryegrass. Cooler air slows leaf growth while soil is still warm enough for active root growth, so the nitrogen goes into building deeper roots and denser tillering instead of fast top growth.

Slow-release, low burn risk: Milorganite 6-4-0 (32 lb)
Main fall feeding: Scotts WinterGuard 32-0-10
Spreads either one: Scotts EdgeGuard Mini spreader

Shallow soil temperatures are in the action band, near the upper edge at 61°F at the Princeton #1 sensor, 46 miles from your location.

Window: Sep 1 to Oct 31. Window typically closes within 7 days.

Cultivation

WATCH

Fall core aeration (cool-season)

Fall aeration after a hot summer relieves compacted soil and gives roots access to air, water, and nutrients heading into the cool-season recovery window. Pairing aeration with overseeding drops the new seed into open holes for ideal soil contact.

Small lawns, by hand: Dolibest manual core aerator
Clay or hard-packed soil, by hand: Hollow-tine core aerator for clay soil
Large lawns, pulls behind a lawn tractor: Agri-Fab tow-behind plug aerator

Shallow soil temperatures are in the action band, near the upper edge at 61°F at the Princeton #1 sensor, 46 miles from your location.

Window: Aug 1 to Oct 31. Window typically closes within 7 days.

No active tasks for your location.
