What is Driving Recent Increases in Fertilizer Prices?
Fertilizer prices are on the upswing again, buoyed by the high prices of agricultural products that have stimulated increased demand. While the general U.S. economy struggles to recover from the financial crisis of 2008, the demand for agricultural products continues in a strong position due to favorable exchange rates, grain usage for biofuels, production concerns […]

Late Drought Causing Problems and Questions for Many
Earlier this fall we made recommendations on how to recuperate lawns after a drought; however, rain has not returned and now we must further adjust our maintenance practices in unirrigated turf areas. The map on the left shows the lack of rainfall in Indiana over the past 90 days. The majority of Indiana has received […]
Late Fall fertilization
Cool-season turfgrass species should be fertilized mainly in the autumn. In addition to a fertilization in September, a fertilization with nitrogen in November will help produce a healthy turf. Lawns damaged during summer months as in 2010 and newly seeded lawns may need this November fertilization to help with recovery and the establishment of new […]
Is it too late to seed? What should we do?
Recently, the question of whether or not it is too late to seed has been posed to me by many. The drought that we have experienced during our optimum seeding window has pushed back seeding dates for many. Now the question is do I seed now, do a dormant seed, or wait and seed in […]
What should I do with all these falling leaves?
There is a myth circulating that returning mulched tree leaves can be detrimental to turfgrass quality. The research shows just the opposite. It is true that heavy layers of tree leaves shading the grass can smother and kill grass. However, our research at Purdue and other universities shows that Tree leaves (both oak and maple) […]
Dealing with Drought
Many turf professionals in central and southern Indiana are trying to figure out how best to cope with the current drought because it is affecting their normal 1) fall seeding, 2) fertilization, 3) herbicide applications and 4) cultivation. Below are some strategies on how to cope with the current situation. The maps below show illustrate […]
Record drought and heat are making seedling establishment a serious challenge
After the extremely stressful summer conditions of 2010 many thin areas in cool-season lawns have been reseeded to restore turf density and improve appearance. Regardless of environmental conditions, establishing a turf from seed is a challenge and the process is as much art as it is science. Seedling establishment requires two steps, germination and development. […]
What to do about deteriorated lawns
This year there were multiple causes for turf decline in home lawns. High temperatures and drought were the primary causes for a decline in turf and an increase in weed incidence. During warm weather (especially temperatures > 87 °F) cool-season grasses like Kentucky bluegrass have trouble making energy while much energy is needed to maintain […]
Fertilizer Recommendations
The amount of nitrogen fertilizer required by turf depends on various management and environmental/management factors (Table 1). A good rule to follow is to never apply more than 1.0 lb N/1000ft2 in any one application. Do not apply fertilizer more frequently than once monthly at a 1.0 lb N/1000ft2 unless you are establishing a new […]
Lawn Cultivation: Is now the time?
Lawns are cultivated (sometimes referred to as aerfication) primarily to relieve soil compaction and manage thatch (organic) layers. Other reasons may be to open the turf canopy and create a seedbed in order to facilitate interseeding or overseeding, or move certain nutrients, composts, pesticides etc. into the rootzone. Common questions regarding lawn cultivation: What are […]

Summer Stress
Part I: Too hot: Why some turfgrass species look poor in summer. There are multiple causes for turf decline in the summer. Cool-season turf areas can decline in the summer because of high temperatures, drought, pest damage (insects, diseases, weeds, others), and due to mismanagement. The general symptoms for many of these causes are usually […]
Wet and Flooded Turf
Wet Lawns Although July has been relatively dry thus far, June brought a great deal of rain and left many lawn soils saturated and wet. Here are a few tips concerning caring for your lawn during wet periods. Flooded Turf Due to the incredible amount of rain Indiana has seen this summer, many homeowners are […]
Rain gardens and turf
There has recently been increased interest in the use of rain gardens to reduce water runoff in Indiana and nationally. A rain garden is a specially constructed area with a berm, planted with various plants, and designed to capture rain water from the roof of a house or building. Rain gardens fill with water after […]
Sharpen Mower Blades
Due to the warm, wet weather we have been experiencing lately, homeowners are having to mow their lawns very frequently. Something to keep in mind throughout the summer is that the more often you mow your lawn, the more dull the mower blades become. Mower blades should be examined a few times throughout the growing […]
May Fertilization
Although it is generally preferable to fertilize home lawns in the fall, a late May fertilizer application can help the turf retain its color and vigor during the summer. If conservative nitrogen rates are used, fertilizer can be applied in late spring without dramatically increasing vertical growth. To aid the turf in keeping its color […]
Managing Seedheads
Kentucky bluegrass, tall fescue and perennial ryegrass all produce seedheads that look unsightly in lawns. These seedheads are easily visible in maintained turfgrass because they grow faster and more unevenly than normal grass blades. Also, since the seedhead stalks are so tough, they do not cut cleanly and leave a light green or white tip […]
Warm Weather and Spring Mowing Woe’s
For those that are managing cool-season lawns like Kentucky bluegrass, the ryegrasses or fescues the unseasonably early warm spring weather has resulted in quite a bit of shoot tissue (leaf clippings) being produced. For many that think they want their lawns to look like a closely cropped and highly manicured golf course, this may have […]
Spring Mowing Tips
Last week’s warm temperatures really made the grass green-up and begin growing which means many people are starting to think about seasonal mowing. Probably one of the biggest mistakes homeowners make is not starting to mow their lawns soon enough. Remember the mowing “rule of thumb”. For optimum turf health “try not to remove more […]
