ID Activity Read the Module pages 1 - 28. Use the presentations: “Typical Lawn Grasses”, “Creeping Bentgrass”, & “Turf Weeds” to complete the following. Which Plant Family do all grasses belong to? Fill in this chart: Genus Common Name: Genus Botanic Name: Bluegrass Ryegrass Fescue Bentgrass Quackgrass Genus Fill in this chart: Common Name Germination Time (days) Veg. Reproduction Competitive height (mow) Kentucky Bluegrass Perennial Ryegrass Cr. Red Fescue Cr. Bentgrass Annual Bluegrass Quackgrass Kentucky Bluegrass: What gives it the rapid repair and excellent wear tolerance? In what Environmental Conditions does it dominate? What does summer dormancy look like, how do we combat it? What is a nurse crop? Why does KB need a nurse crop? What do we usually use KB for? What is the fertilization rate of KB? _________________ Kg of actual N/100m2/growing month Perennial Ryegrass Why might I use this as a nurse crop? Why might I use this as a quick cover crop in the spring? What is endophyte enhanced seed? Why does it have less thatch development? Why would I not use this as the main percentage of my lawn seed blend? In what kind of situations would I want to use a ryegrass blend? How much fertilizer does it need, relative to KB? Creeping Red Fescue In what environmental conditions does Creeping Red Fescue thrive? Why does it grow slower than other grasses? Why could this species be more prone to thatch than others? What other fescues are commonly found in lawn blends? Why are fescues the “new standard” in low maintenance lawn applications? What kinds of places might Tall Fescue be a great choice for? If it's so great, why don’t we use Tall Fescue all the time? Creeping Bentgrass Why is CB so great for Golf Greens? What problems arise from using CB because of its stoloniferous growth habit? List at least 2 other downsides: What special maintenance practices do we employ to manage CB? As a result of all this extra care needed, where do we most often use CB? Quackgrass What is allelopathy? Why is it that I can go out, pull all the Quackgrass in a bed, and then come back next week and there’s even MORE there than before? When is the best time to spray it, and with what should I spray it? What is the best way to make sure that I don’t get Quackgrass in my new lawn? What is the best way to reduce Quackgrass invasion in planting beds? Annual Bluegrass Why does AB have a circular growth habit? In what conditions is AB very competitive? Why do we consider AB a weed? How can I get rid of AB when it invades a KB stand? What will happen if I allow my grass to grow longer than the recommended competitive height? What kind of turfgrass blend would be a good choice for a daycare (think low maintenance, mixed exposure, children playing on it)?
