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 a specific fertilizer to apply, but rather we must recommend fertilization rates in pounds of nitrogen per thousand square feet or lbs N/1000ft2. You can use our fertilizer calculator at http://www.agry.purdue.edu/turf/fertcalc/Fertilization%20calc.html or you can use […]
Recent cold temperatures should have little effect on winter survival of Bermuda, zoysiagrass, or cool-season turfgrasses.
The recent cold snap has raised a number of questions about survival of warm-season turfgrasses, especially given the relatively recent popularity of bermudagrass for fairways and athletic fields. Though winterkill is highly variable, all turfgrasses are most susceptible to cold temperatures very early and very late in the winter and thus we wouldn’t expect much […]
It’s not too late to do a lot of good for your lawn
The fundamental principle for effective lawn pest control is to “Cultivate a dense, healthy turf”. One way to promote turf density is to properly feed the plant at a time when it is most capable of utilizing these nutrients for purposes other than leaf growth. For cool-season grasses shoot density naturally increases during the autumn […]
Cold, rainy, windy conditions playing havoc on fall applications
The window for effective broadleaf weed control is closing fast and we normally see good control of difficult-to-control weeds like ground ivy until about the end of October. However, you may still get adequate control of easier-to-control weeds like dandelion through the first week of November or as long as daytime highs are 50F or […]
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 […]
Cool, damp weather hindering fall turf work
The almost constant rain/drizzle/wet conditions coupled with early unseasonably cool temperatures have hindered progress in fall maintenance. All is not lost though because warmer and drier weather is in the forecast. Seeding: It’s too late to seed throughout IN to expect expect germination and enough maturation of the grass to survive winter temperatures. A previous […]
Keep mowing and don’t set the mower down
Many people ask how long to continue mowing into the fall. The answer is to keep mowing as long as the grass continues to grow which is normally into late October or early November. Frequency of mowing can decrease but continue to mow into the fall. Also avoid the urge to set the mower down […]
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 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 […]
Professionals Only: Dry weather hampers broadleaf weed control, fertilization
Though we are now in the window for maximum broadleaf weed control and fall fertilization, the dry weather throughout most of the state is hampering applications. Avoid herbicide and/or fertilizer application to drought stressed or dormant turf to limit turf damage and maximize intended effect of the application. On turf that’s still green (like in […]
Cool temperatures allow a jump on beneficial fall maintenance practices
The recent record or near record low temperatures combine with adequate soil moisture is advantageous for our cool-season turfgrasses, especially compared to the typical August-September heat and drought. Fall fertilization can begin anytime, especially with rain in the forecast to help water in the application. White grub damage will likely be minimal with overall health […]
Drought affects all turf areas differently
We are fielding a number of calls like “Why is my lawn is turning brown while my neighbors isn’t, even though neither of us irrigate?”. On any given turf area or in a neighborhood, we can see a wide variety of responses to the current drought. Following is a list of factors that will affect […]
Now is the Time to Start Improving Your Lawn
Tired of the way your lawn looks? If it hasn’t looked up to par this summer with the relatively good weather, it never will and reseeding your lawn is an option. Mid-August is the best time to seed a new lawn or overseed an existing lawn. If the lawn is just thin and needs a […]
Using clover for lawns?????
Recently I was contacted by a major newspaper reporter who was writing an article about more sustainable lawn systems, or lawns that would required fewer inputs, and was inquiring about the feasibility of using clover as a lawn turf. After a brief head-scratching and a few questions about his intent we had a nice conversation […]
Summer Mowing and Fertilization
By the time you read these words the longest day of the year has approached and the official calendar “Summer” season will have begun. Just as the weather changes as we transition between seasons from late-Spring to Summer the turfgrass plant changes too. First, both air and soil temperatures rise beyond what is optimal for […]
Effects of wet spring on turf
With the well-above average rainfall this spring, questions are starting to arise about the short and long term effects on lawn, golf, and sports turf: Rooting-Though no official records are kept, rooting tends to be shallow and limited on water-logged soils because of a lack of oxygen. Effects of a wet spring like this spring […]
White Clover in Golf Courses, Sports Turf, and Lawns
The small white flowers of white clover are very visible right now and it may appear that clover is taking over, especially under-fertilized turf areas. Clover is a legume and is very competitive under low N conditions, so increasing annual N is best method to help exclude this weed. However, its spreading stolons make it […]
Changing soil pH under turf
Soil testing is important in turf to help determine the soil pH and fertilization needs, especially for potassium and phosphorus. Acceptable soil pH for turf is between 6.0 and 7.5, but often soil tests show pH levels higher or lower than this. pH higher than 7.5: Some firms will recommend applying sulfur to reduce the […]
Responsible fertilization of home lawns
A properly fertilized turf has fewer weeds, is more resistant to insects and disease, and decreases water runoff compared to malnourished turf. Concern over the negative effects of nutrient enrichment on water quality is a growing public concern and has led many to start to question turfgrass fertilization practices. Although both nitrogen and phosphorus may […]
Volunteer tree seedlings in lawns?
I’ve gotten a number of calls asking about volunteer maple and other tree seedlings growing in lawns. These are direct descendents of a neighborhood tree whose seed pods released last spring/summer. You can either stake a couple of these small trees and nurture them over time to become a formidable maples, or you can control […]
Spring Lawn Aerification
Aerification, sometimes called core cultivation is a supplementary lawn cultural practice primarily used to relieve soil compaction and remove thatch (the spongy layer of undecomposed stems at the soil surface). This practices is not necessarily essential to maintaining a lawn, however, it can be very beneficial to most turf areas. In addition, to the aforementioned […]
