How to Select a Crabgrass Preventer from the Store – Homeowners
Crabgrass is a summer annual weed that germinates in lawns each spring (click here for crabgrass identification information). Preemergence herbicides prevent emergence of crabgrass plants from the soil. These products must be applied prior to crabgrass germination which could occur as early as April 1 in southern Indiana and three or more weeks later in […]

Seed Early in the Spring for Better Success
Now that the snow has melted, you might be seeing some areas damaged from snow plows or other winter vehicle traffic that need repair. Seed planted now (late March) will begin to germinate in early to mid-April. The earlier in the year that you seed, the more time the turf will have for […]
This Week Felt Too Much Like 2014!
This cold weather reminded me of the cold weather we experienced last winter. While it is too early to tell what effect the weather might have had on the turf, it could have damaged some warm-season turf areas in north central Indiana (like our bermudagrass and zoysiagrass areas at the Daniel Turf Research Center) where […]

Is it Too Late to Apply My Last Nitrogen Fertilization?
Fall is an important time to fertilizer our cool-season turfgrasses. Fall nitrogen promotes good root development, enhances storage of energy reserves, and extends color retention in cool-season lawns. Most of the benefits from late fall nitrogen will be seen next spring and summer with earlier green-up, improved turf density, and improved tolerance to spring diseases […]
Broadleaf Plantain
Broadleaf Plantain Biology: Broadleaf plantain (Plantago major) is a perennial, broadleaf weed that can be found in nutrient-poor soils; however, they prefer nutrient rich-soils that are moist and often high in calcium. Broadleaf plantain is a common weed in turfgrass, nurseries, and landscapes as it can tolerate very low mowing heights. It germinates […]
Words You Might Hear a Turf Nerd Use
A nerd is an intelligent but single-minded person obsessed with a nonsocial hobby or pursuit1. Therefore, a turf nerd is someone single-minded towards turf, obsessed with turf, and a bit nonsocial. I suppose that described me pretty well. To help increase your turf nerd quotient (only nerds use words like quotient), I thought I would […]
Prostrate Spurge
Prostrate Spurge Biology: Prostrate Spurge (Euphorbia humistrata) is a summer annual broadleaf weed that can be found in dry/sandy and/or nutrient-poor soils along with compacted, weakened or disturbed turfgrass and landscape sites. Look for it first in driveways and sidewalks or in potted plants in a landscape or nursery as temperatures […]
Plant Turf Seed or Control Weeds First?
A common question this time of year is whether to plant turf seed now and control weeds later OR to instead control the weeds now and then seed later. Here are my thoughts. Cool-season turf seed mixture. Option 1 for areas with mainly broadleaf weeds and a few annual grasses: Plant now and control weeds […]
Fescue. You mean there’s more than one kind?
Typical conversation about fescues. Bill: What kind of grass do you have? Bob: Fescue. Bill: What kind of fescue? Bob: You mean there’s more than one kind? Bill: Yes. As I travel around the region and give presentations or respond to email and phone questions, it is very common for me to enter into a […]
Start Seeding Cool-Season Turf Now
The best time to seed a cool-season lawn is in the late summer to early fall. Adequate soil moisture, warm soil, and limited weed pressure allow for excellent seedling growth. Normally, we recommend seeding between August 15 and September 15 as the optimum seeding window. However, due to our cool summer and a […]
Watering Newly Seeded Areas
Water is necessary to initiate the germination process in seeds. As the seed imbibes water, enzymatic reactions within the seed trigger the germination process. Enzymes breakdown the energy stored inside the seed endosperm and this energy is used by the seed embryo for growth. The first visible step in the germination process is the emergence […]
2014 Turf and Landscape Field Day a Success
On Tuesday, July 15, 2014 the Purdue Turf Program, the Purdue Green Industry Working Group and the Midwest Regional Turf Foundation successfully hosted the Turf and Landscape Field Day. Jackets were needed at this year’s field day as the high temperature was 69 °F which is the coolest field day on record! The Turf and […]
Birdsfoot Trefoil
Birdsfoot Trefoil Biology: Birdsfoot trefoil (Lotus corniculatus) is a perennial broadleaf weed that is often found on drought-prone and low-fertility soils. It germinates from seed primarily in the spring but sometimes in the fall depending on temperatures. The plant quickly spreads into large colonies by developing stolons and rhizomes during the […]
Weed Management Next to Sidewalks and Driveways
Weed management next to sidewalks is difficult for several reasons outlined below. These “hot spots” for weed invasion become quite evident during summer as weeds encroach and turf quality declines. The below section outlines some of the causes for hot spots and how to best manage weeds in these areas. Soils are shallow in these […]
