No you are not imagining this. The specks are actually moving. That is because they are actually tiny mites called clover mites. Clover mites can become annoying household pests, especially in and around homes where new lawns have recently been established or where there’s a heavy growth of well-fertilized grass close to foundation walls. They…Read more about Small Moving Specks on the Windowsill?[Read More]
We continue to receive reports of spring-time turfgrass damage caused by raccoons or skunks. These animals are not feeding on the grass but rather are foraging for below ground, high populations of white grubs. As the vertebrates forage, they turn over great clumps of turfgrass resulting in an area that resembles a war zone. Sometimes…Read more about Skunks and Raccoons causing Havoc?[Read More]
Preemergence herbicides prevent emergence of crabgrass plants. These products must be applied prior to crabgrass germination which on an average year could occur as early as April 1 in southern Indiana and three or more weeks later in northern Indiana. It is essential to apply these products early in spring prior to crabgrass germination. Last…Read more about Cooler Than Average Spring Temperatures for Some May Extend the Window for Preemergence Herbicide Applications[Read More]

Kentucky bluegrass (Poa pratensis) is beginning to produce seedheads this time of year which are difficult to mow and can cause a lawn to appear uneven. However, there are other grasses such as annual bluegrass (Poa annua) that also produce similar looking seedheads. Annual bluegrass is a winter annual or weak perennial turfgrass species which…Read more about To whom does this seedhead belong?[Read More]
Fertilizer loading Fill spreaders over a hard surface such as a driveway, sidewalk, or other hard concrete or asphalt surface. This will allow easy clean-up if any material is spilled. Fertilizer spills over turf usually result in turf death to the affected spot. If product is spilled during loading (A), clean-up the material immediately by…Read more about Spilled Fertilizer: Loading and Application[Read More]
Nimblewill (Muhlenbergia schreberi) is a weed that thin patches in lawns. Since nimblewill is a warm-season grass, it will turn brown at the first frost and is very slow to green-up in the spring. The brown patches seen in lawns in the early spring may be nimblewill contamination. This weed spreads from seeds produced and…Read more about What’s that brown spot: Nimblewill in lawns[Read More]
Spring is almost upon us and overwintering white grubs will soon be emerging from the depths to continue feeding for a short time before they pupate. These overwintering grubs typically spend the frigid months of December – February deep in the soil profile (up to 12 inches deep) to avoid freezing. As soil temperatures begin…Read more about Spring Grub Control Not Your Best Bet[Read More]
This turf tip is part of a three part series on spring seeding. Most turfgrass herbicides are intended for use on established grasses. Thus, herbicide use on newly planted grasses should be very conservative. If possible, wait until the grass has gone through several mowings or a full growing season before using chemical weed control….Read more about Part III: Controlling broadleaf weeds in newly seeded areas[Read More]
Melting snows revealed some significant snow mold damage. As you know there are two types of snow mold diseases, gray snow mold (aka Typhula blight) and pink snow mold (Microdochium patch). Although they create similar symptoms (circular patches of tan turf—sometimes with orange/brown margins, Fig. A, C, D) the pathogens are not closely related and…Read more about Snow mold damage – 2011[Read More]
Part II: Preemergence and postemergence herbicides for crabgrass control in newly seeded areas This turf tip is part of a three part series on spring seeding.
