Is Poa annua a good grass for your golf course?
“If you have good exposure, good air movement, great internal drainage, bent is going to do just fine, and it’s a good grass. But on old soil-based push-up greens with no internal drainage, poor air movement and lack of sunlight, Poa is going to thrive.” 4 It’s possible to completely eradicate Poa annua from a cool-season golf course.
What happens when Poa takes over Bermuda?
What’s more, Guilfoil says, once poa gets a foothold, it takes over quickly. It outcompetes Bermuda in the cooler months, and then, come summer, when the poa dies, it leaves browned and barren patches in its place.
How do you manage Poa on a golf course?
“To have a very effective Poa management program you’ve got to manage the entire golf course, not just the greens and tees. Poa can be very easily tracked in from the fairways and the rough surrounding the greens.” 6 You can’t maintain Poa in hot, humid weather.
What is the difference between Bermuda and Poa Anna grass?
Bent grass greens are usually smoother, faster and hold their line due to the finer blades of grass. Play more break on the bent greens and expect the greens to roll quicker than Bermuda greens. Poa Anna greens are normally the bumpiest and require the most patience.

Why is there no poa at TPC Harding Park?
Poa is prevalent around the West, all the more so the closer to the coast you get. Eventually, it takes over a golf course, unless a superintendent stands in its way. Many course caretakers try combating poa with herbicides and other applications. Others live with it, or tend lovingly to it. One of Ken Nice’s mentors once told him that more superintendents lose their jobs trying to kill poa than they do by simply trying to manage it. Once poa is in, it’s hard to get out.

During the second round of the 2020 Farmers Insurance Open at Torrey Pines, Tiger Woods four-putted the 1st green.
What makes poa so bumpy?
For starters, it doesn’t have to be. Early in its life, Ken Nice says, “poa is coarse and rank and it puts out a lot of seed heads.” The more seed heads, the less smooth the putting surface. Those seed heads also create a silvery sheen on greens, and there aren’t many people who like that look. Here’s the thing, though. Over time, and under regular maintenance practices such as tight mowing and verti-cutting, poa evolves. It produces fewer seeds. It firms up and smooths out, creating surfaces that can be as pure as any. Oakmont’s fabled greens are poa. At Bandon Dunes, three courses with greens that were originally planted to fescue and bentgrass have since transitioned naturally toward poa without any ill effect. In fact, guests surveys show that golfers prefer them now to how they played before.
Why is my poa grass bumpy?
Because poa grows faster than other types of grass, it can lead to bumpy surfaces late in the day. Because it also demands more water than some other strains, it is prone to getting spongy and pocked with footprints. But again, Ken Nice points out, it doesn’t have to be that way. Maintenance is a major factor.

managing Poa annuagreens. Add to the equation that there is very limited fungicide availability in France and many other areas in Europe, and Poa annuais not a good choice despite the ideal conditions for growth. In the golf course industry, it is safe to say that Poa annuais the plant that we love to hate. However, many suc- cessful U.S. Opens have been played on Poa annuagreens. In mild climates where Poa annuathrives, it can be a very good putting surface, but the problems with heat tolerance, cold tolerance, disease, and uneven growth (just to name a few), can make it a difficult species to grow at certain times of the year. In these areas of the world, if you were to ask golf course superintendents if they had a choice between Poa annuaor creeping bent- grass, most would choose bentgrass. In climates in the transition zone, it is a little more straightforward: Poa annua
How to control Poa annua?
The earliest attempts to control Poa annua was to simply cut it out when it appears. This still works, but it is very labor intensive and only those with the highest budgets can generally follow this procedure. Preemergence herbicides have long been proposed as the solution and they can provide some control. However, the seed for Poa can live for years in soil and plants will emerge every time there is an opportunity for germination, such as in a cleat mark on a sports field. If it were a true winter annual, preemergence herbicides could work, but there are also many perennial biotypes in most areas, and the living plants are not affected by preemergence materials.
How does Poa Annua grow?
This species appears in the botanic literature as a winter annual, which means that it germinates late in the summer and into the fall, lives through the winter as a mature plant, and in the spring it produces a seed crop and simply dies. It is better adapted to low mowing heights than most of our turf species and tends to crowd them out at low mowing heights. It thrives under an intense management system. Lots of fertilizer and water helps it get a foothold, whereas turf that is subjected to moisture stress and lower fertility levels rarely develops a problem. It can produce a quality stand of turf in cool and wet conditions, but the fact that it dies in mid-season can be a real problem for summer sports, such as baseball.
What is the best herbicide for ryegrass?
These postemergence herbicides can also be quite variable in their effect on desirable turf species. One of the most effective postemergence herbicide that I worked with has been Prograss (ethofumesate). This product is very effective at killing most Poa biotypes from perennial ryegrass. The catch is the perennial ryegrass. It easily damages Kentucky bluegrass and other species commonly used in sports turf areas. If your field is perennial ryegrass only, Prograss may be the product that you need, but this is rare.
How long does PoA seed live?
Preemergence herbicides have long been proposed as the solution and they can provide some control. However, the seed for Poa can live for years in soil and plants will emerge every time there is an opportunity for germination, such as in a cleat mark on a sports field.

Much of my career has been spent on trying to kill annual bluegrass, better known as Poa annua in golf course turf. While it does occur in other turf areas, such as lawns, it has always been on the golf course where this species has presented the biggest problem. The very low mowing height and intense management regimes used on golf courses provide an ecological advantage to Poa annua and it easily outcompetes other preferred grass species.
