Garden centers often advertise applying gypsum to your lawn to “decompact” the soil by improving the structure of clay soil. This only works in soils common in the arid western US where there is much more sodium than calcium in the soil. This does not work in Indiana because the parent material for most of […]
Rotary spreaders are widely used by homeowners and professionals for most applying fertilizers and pesticides. So to test your knowledge, here’s a question that I constantly ask of professionals and do-it-yourselfers when spreading fertilizer back and forth on a turf area: A. Your current pass should spread product so it just touches the edge of the […]
I’ve gotten a number of calls on winter damage on lawns and other high mowed turf areas. Thankfully this is fairly rare in most winters throughout Indiana. Winterkill can be fairly complex resulting from desiccation with drying winds, freezing of the plant crown with quickly dropping temperatures after spring green up, and/or from direct cell […]
Though lawns in southern Indiana may have already been mowed a couple of times, mowing is just starting from Indianapolis north. Mowing is the most expensive and laborious maintenance practice on turf, but it also has the largest effect on long-term performance: It is better to mow too early rather than too late in the […]
Many different strategies exist on spring fertilization, but the one fact agreed upon by all turf specialists is to avoid applying heavy nitrogen (N) rates in March or April. Heavy rates would be anything greater than 0.75 lbs of quickly available N/1000 ft2, which causes excessive shoot growth and results in frequent mowing. Furthermore, excess […]
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/1000 sq ft. You can use our fertilizer calculator at www.agry.purdue.edu/turf/fertcalc/Fertilization%20calc.html […]
All cool-season turfgrasses benefit from fall nitrogen (N) fertilization, regardless if it is a lawn, athletic field, or golf course green, tee or fairway. Normally fertilization should begin in mid-September and continue one or two more times until about mid-November. Starting the fertilization program in September will take advantage of favorable growing weather and encourage […]
During spring green-up, home lawns may reveal many variations in color, growth rate, and leaf width. This variation can be due to some of the following reasons: Species and cultivars: Perennial ryegrass is always the first of the desired cool-season grasses to green-up, followed by tall fescue and eventually Kentucky bluegrass. Within a species, different […]
As lawns are greening up, many calls are coming in about damage left over from last summer or perhaps even winter damage. Unfortunately, spring seeding is difficult at best because of pending hot weather and/or weed and disease pressure. Late summer (August) is easily the best time to seed cool-season grasses, but sometimes turf must […]
With the fairly wet weather last fall, football and soccer fields have taken a beating. The fields that were aggressively aerified, fertilized, and dormant-seeded last fall should improve dramatically by mid-May. Though improvement won’t be as efficient done now compared to the fall, there is still time to help a field if you missed out […]
Most turfgrasses have leaves that only live for 30-60 days and thus constant growth is require to maintain ground cover, especially with any pets, children, or other traffic. The Holy Grail of “no-mow” turf is unlikely because the turf stand will thin allowing lots of weeds to encroach. That being said, any grass can be […]
After widespread flooding, many question how well turf will survive. Turf injury from flooding depends on water temperature, species, duration of submergence, and depth of submergence. Turfgrasses can withstand submersion for up to 60 days when water temperatures are 50 degrees or less. Injury is increased under stagnant water compared to moving water, and injury […]
Healthy turf areas provide many environmental and recreational benefits. A properly fertilized turf has fewer weeds, is more resistant to insect feeding and is less disease prone than malnourished turf. Furthermore, a dense turf slow and decreases water runoff following storm events which helps reduce flooding in urban environments. Concern over water quality is growing […]
We get a ton of calls and email inquiring about low maintenance lawns. Simply put, there are no silver bullet grass species that are low maintenance and will also survive summers and winters in IN. That being said, hiring professionals to mow and maintain your lawn is the best method for reducing your input. Following […]
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 […]
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 […]
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 […]
Now that cooler temperatures and at least a little rain is back, it’s critical to help turf recover. Though we’re out of the optimum seeding window in the northern 2/3rds of Indiana, most effective recovery will be through fertilizing with 0.75-1.0 lbs N/1000 every three to four weeks until the grass stops growing in early […]
I have received a number of email questioning the wait for seeding after glyphosate applications. Glyphosate has no soil activity and will therefore not affect seedlings when seeded even the same day of application. However, for maximum control of tough-to-control weeds with stolons or rhizomes, a 7 day delay is recommended before raking or aerification […]
Though much research over the years has shown that when fertilizer is applied properly to turf, it does not leach or runoff. The key to this is proper application as careless applications can cause problems. Following is a quick list of precautions when applying fertilizer (or pesticides) to your lawn. ·Apply the right rate and […]
