Dormant Sand Topdressing. Does it help Creeping Bentgrass Spring Green-up?

A research study was initiated at Purdue University to evaluate two sand topdressing products for their ability to enhance creeping bentgrass spring green-up. Treatments were applied at three application rates in the third week of January 2004 to a ‘Crenshaw’ creeping bentgrass stand being grown on a native soil rootzone. Observations to date indicate that…Read more about Dormant Sand Topdressing. Does it help Creeping Bentgrass Spring Green-up?[Read More]

April 12-13 3b RT Workshop to complete requirements for pesticide licensing

Are you interested in making pesticide applications to your customers’ lawns?

Calculating the pounds of fertilizer to apply

There are literally thousands of fertilizers and fertilizer/pesticide combinations available to homeowners and professionals. Therefore, we can’t recommend how many pounds of fertilizer to apply, but rather we must recommend fertilization rates in pounds of nitrogen per thousand square feet or lbs N/1000ft 2 . Calculating the amount of fertilizer to purchase and apply is…Read more about Calculating the pounds of fertilizer to apply[Read More]

Why we don’t recommend specific fertilizer/herbicide combinations for homeowners

We’ve received a number of emails asking for specific product recommendations for XYZ town in IN or IL, or even as far away as NY. Its very difficult, OK impossible, for us to recommend specific fertilizer/herbicide combinations because there is a large number of brands and an even larger number of fertilizer/herbicide combinations available on…Read more about Why we don’t recommend specific fertilizer/herbicide combinations for homeowners[Read More]

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…Read more about Timing of Preemergence Herbicides[Read More]

New Edition of Re-entry Precautions for Turf Fungicides – March 11, 2004

Spring N: Do-It-Yourselfers vs Professional Recommendations

We recommend waiting until mid-May to fertilize for the vast majority of do-it-yourselfers, while professional lawn care operators often apply fertilizer early in the spring with the preemergence herbicide. These two seem to contradict each other. We know that a very low rate of N applied in the spring will green up the turf quickly…Read more about Spring N: Do-It-Yourselfers vs Professional Recommendations[Read More]

To Fertilize Lawns or not to Fertilize: That is the Question

For the vast majority of homeowners, resist the urge to fertilize now. Fertilizing now can encourage too much growth and could lead to problems later this summer such as poor root growth and disease. Additionally, since spring rains play havoc with mowing schedules, nitrogen fertilization can further complicate your mowing schedule by causing grass plants…Read more about To Fertilize Lawns or not to Fertilize: That is the Question[Read More]
