Spring Dandelion Control Still Not as Effective as Fall Control
The annual bloom of dandelions is already here in southern and central Indiana. This marks the beginning of the second most effective period for controlling broadleaf weeds. The optimum time to control dandelions and other broadleaf weeds is in the fall and the second most effective time is in late spring, at or shortly after […]
Turfgrass Does not Perform Well in the Shade (Period)
We have received a ton of calls in the last week about improving shaded lawns. Following is a summary about shaded lawns: Turf does not perform well in the shade “Shade-adapted“ grass species and cultivars will always perform better in full sun compared to shade (regardless of what the label states) As […]
March 30-31 Workshop to complete requirements for pesticide licensing (3BRT)
Are you interested in making pesticide applications to your customers’ lawns? Indiana law says anyone who wants to apply turf pesticides (and that includes weed killers, weed and feed products, insecticides, and other over-the-counter pesticides) FOR HIRE must be licensed to do so. To obtain a commercial turf pesticide applicator FOR HIRE license, you’ll have […]
Common Chickweed in New Seedlings
Common chickweed is currently dominating any fall- or dormant-seedings (including my lawn). Common chickweed is a winter annual, so it germinated last fall, grew well into December and is starting to spread with the temperatures this weekend (see accompanying photos). In established lawns, I wouldn’t recommend spraying it because it will die with the first […]
Spring Weed Control or Seeding?
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 […]
Herbicide Delays after Seeding
Almost all herbicides will affect turfgrass seedlings and application delays are usually needed following seeding. Following is information gleaned from available labels of most herbicides or herbicide types that would be used in Indiana. This is intended to provide a general idea of the limitations of each active ingredient, but please refer to the actual […]
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 […]
