After widespread flooding, many question how well turf will survive. Turf injury from flooding depends on water temperature, species, duration of submergence, and depth of submergence. Turfgrasses can withstand submersion for up to 60 days when water temperatures are 50 degrees or less. Injury is increased under stagnant water compared to moving water, and injury […]
Healthy turf areas provide many environmental and recreational benefits. A properly fertilized turf has fewer weeds, is more resistant to insect feeding and is less disease prone than malnourished turf. Furthermore, a dense turf slow and decreases water runoff following storm events which helps reduce flooding in urban environments. Concern over water quality is growing […]
With last year’s brutal summer and early fall, many areas are in need of reseeding. The question comes up about seeding and weed control: should the weeds be controlled first or should the seeding be done first? This seems like a simple question, but it’s fairly complex depending on the turf and weed species present […]
Per the earlier Turf Tip, select preemergence herbicides with as little nitrogen as possible to reduce the growth flush and maximize long-term health of the plant. The problem is finding a product with little or no N. Do not make the mistake of settling for a high N product and then reducing the application rate. […]
We get a ton of calls and email inquiring about low maintenance lawns. Simply put, there are no silver bullet grass species that are low maintenance and will also survive summers and winters in IN. That being said, hiring professionals to mow and maintain your lawn is the best method for reducing your input. Following […]
There are many, many formulations and combinations of preemergence herbicides available for the professional. Following are some suggestions for purchasing and using preemergence herbicides. Control from every preemergence herbicide can vary from year to year, or location to location. Therefore, you can’t judge the performance of a product or a specific rate of that product […]
If a preemergence herbicide is justified on a turf area, the timing of application is important. In theory, applying too early will expose the herbicide to soil microbes and processes in the soil that may break it down, allowing crabgrass to germinate during the latter part of the summer. Conversely, applying too late may miss […]
If a preemergence herbicide is justified on your lawn to control crabgrass now, most of those are available combined with fertilizer and you are forced to apply a fertilizer now. Look for a product with low nitrogen and be sure the majority of the nitrogen is a slow release N. Slow release sources include sulfur- […]

Winterkill in warm-season grasses is highly variable and difficult to study by scientists. Because of this, our understanding of winterkill is based on science as well as practical experience and observation. Since winterkill in warm-season grasses can be affected by genetics, temperature extremes, and management factors, an endless combination of these factors can interact to […]
We are out of the optimum window for seeding turfgrasses in Indiana. However, many are still hoping to seed. Following is a summary of our studies in the early 90’s on seeding at less than optimum times of the year. For optimum establishment, seeding should be done in late August or early September. Waiting as […]
A November application of fertilizer is extremely important to keep your lawn healthy and looking good this fall and next year. Late fall N promotes good root development, enhances storage of energy reserves, and extends color retention this fall. Most of the benefits from late fall N will be seen next spring and summer with […]
The trees are dropping their leaves and it is important to prevent a heavy layer of leaves from building-up on your turf before winter. Heavy layers of tree leaves will shade the grass can smother and kill grass yet this fall. Plus tree leaf cover favors a damaging winter turf disease called snow mold. The […]
Currently advertised on television and in home improvement stores are “winterizer” fertilizers. There’s good and bad about winterizer fertilizers. It’s good that they are emphasizing fall and late fall fertilizer. These fertilizers usually contain the same amount of potassium as nitrogen (nitrogen is the first of the three prominent numbers on the bag while potassium […]
