Timing of Preemergence Herbicides
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 […]
Choose Preemergence herbicides with as Little N as Possible
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- […]
Rain Gauge Volunteers Needed for CoCoRaHS
What is CoCoRaHS? CoCoRaHS, the Community Collaborative Rain, Hail and Snow network, is a unique, non-profit, community-based, high density network of volunteers of all ages and backgrounds, who take daily measurements of rain and snow in their yards, athletic fields, or golf courses. And now, thanks to a partnership between the Indiana State Climate Office […]

November Fertilization is Money in the Bank
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 […]
Now is the Time to Control Dandelions
Those dandelions, clover, and other broadleaf weeds that were a problem all summer should be controlled this fall. The period from late September through October is the ideal time to control broadleaf weeds in turfgrass because broadleaf weeds are most susceptible to herbicides at this time. The turf and weeds must be green and actively […]
Winterizer Fertilizers
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 […]
Keep Mowing to Mulch Those Tree Leaves!
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 that 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 […]
Turf 101: Why does a November application of fertilizer work?
Nitrogen stimulates increased photosynthesis and the extra energy derived from this goes directly into growth, respiration to maintain the plant (similar to humans), or into storage. In early November, the temperature is still adequate for photosynthesis, but cool enough to minimize respiration demands and too cold for significant growth. Therefore, most of the extra energy […]
Turf 101: Why are broadleaf herbicides more effective in the fall than spring?
Late September through October is the best time to control weeds like dandelion, clover, and chickweed with an application of a broadleaf weed herbicide. Broadleaf weed herbicides are systemic and move through the plant in the phloem, which also transports photosynthate. The more areas of the plant that the herbicide translocates to, the more effective […]
Hot August and September = Poor Rooting = Bad Footing for Sports Fields
For anyone who watched major college football in the Midwest this fall, you’ve noticed that the fields are tearing up with divots and blow outs. Some major universities have even resodded their fields after the opening few games in hopes of improving traction. In a nutshell, this is why fields are tearing up: Root […]
Randy Brehmer Receives Agronomic Award of Distinction from Purdue University
At this weekend’s Homecoming activities, Randy Brehmer will receive the Agronomic Award of Distinction from Purdue’s Department of Agronomy. This award is reserved for those who have gone above and beyond the call of duty to help the Department of Agronomy and Randy is especially deserving of this award for all he has done to […]
How late can you seed?
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 […]
Tough Year for Turf in Indiana
The summer’s heat and humidity have taken an unusually high toll on turf in lawns, athletic fields, and golf courses. Most of the decline can be attributed to poor root growth weakening cool-season grasses and starting an avalanche of secondary factors leading to further decline. Root growth of cool-season grasses reaches a peak in mid-spring […]
No Rush on Broadleaf Weed Applications
After the rains have returned, broadleaf weed herbicides should become effective. However, don’t be in too much of a rush to apply because our data suggests that better control is obtained with October applications in than in September. We found that herbicides applied from October 1 through November 1 improved long-term ground ivy control compared […]
September is a Crucial for Fertilizing All Cool-Season Turfs
With the returning rains in the state, now is the most important time to fertilize cool-season turfgrasses like creeping bentgrass, Kentucky bluegrass, perennial ryegrass, and tall or fine fescue. September fertilization is crucial on all turf areas regardless if it is a lawn, athletic field, or golf course green, tee or fairway. Fertilization in mid-September […]
Time is Running Out to Seed Your Lawn
It now almost too late to seed this fall to expect the seedlings to form a good stand before winter, especially with the dry conditions that remain in the forecast. The optimum time to seed cool-season turfgrasses is between Aug. 15 and Sept. 15 in central IN, a week earlier in northern IN, and a […]
