New trash cans

With our core values in mind, especially our environmental responsibility, we purchased new trash/recycling combination units this year. The next time you are out you will see these stations across the course.

These new trash cans are an upgrade in several different ways. First, and most important, we now give our members the option to recycle. Though simple, this is a major improvement. In the past, there was not an option to recycle while on the golf course, so all trash generated was disposed of as trash and not separated as trash or recyclables. Bretton Woods cannot truly maintain an environmentally responsible footprint if we are not offering the opportunity to recycle wherever possible. We will also be using compostable trash bags in both the trash and recycling compartments of the new trash cans to lower our waste.

Also, these new units are much more clean and attractive than the old trash cans made of wood, and now match other units around the Bretton Woods facility. While the wooden trash cans were functional, they did not have a crisp, clean, tidy look. There will also be far less maintenance and upkeep on these new trash cans compared to the wooden versions. There may be some repairs over the years, but the wooden trash cans were getting old. We had to completely rebuild/replace several units a year along with repainting them each winter also. That labor can now be directed to other tasks.

Lastly, the new trash cans are made of recycled material themselves. There is a stamp on the side of each new trash can noting that it was made from approximately 1230 reclaimed milk jugs. Using recycled material was a key factor in our decision to purchase these specific units.

Nothing states our value of being environmentally responsible better than offering the opportunity for our golfers to recycle. Furthermore, purchasing trash cans constructed of recycled material only adds to this commitment. We hope you enjoy and utilize the new units while you are on the course.

Bermuda grass weed spray

This blog post is coming out late because we spent the entire morning making our herbicide application to fairways. We had a small window of opportunity of dry weather and calm or light wind conditions that we seized. Now all the fairways have been sprayed with a chemical to kill the weeds as well as a small amount of fertilizer to help the Bermuda grass get going.

This is one of the hardest tasks we do on the course. The precision and focus required makes it a very difficult application. The chemical we use kills nearly everything except Bermuda grass. It is a very useful and effective tool for killing weeds in the fairways. However, if there is one slip in concentration and the chemical gets in the rough or collars or anything besides Bermuda grass and that spot is dead. In addition, we strive to never close the course for any reason and close 9 holes only for aeration, so this weed killer application must be made ahead of play but be dry before any golfers walk through it. This is also a difficult balancing act that requires a lot of communication between the Grounds department and the Proshop. Finally, once the spray is complete, the last, difficult aspect is cleaning the sprayer thoroughly. Any residue left in the tank could potentially harm the greens or rough next time we spray. This could be catastrophic. So there is a great deal of time spent running a chemical cleaning solution through the tank repeatedly.

Overall, the application went well and we expect to see results very soon. It is also a relief for our department to be done with this particularly big hurdle.

Bermuda grass weed control

As we continue to hone our weed control program for the fairways, there are times when some weeds may be evident. Right now, there are visible weeds in the fairways that stand out in great contrast to the mostly dormant Bermuda grass. We will be eliminating these weeds very soon and we will continue to tighten the defense against any weeds as we move forward.

Our pre-emergent weed control is in place on the Bermuda grass. This ensures that no new weeds will be appearing in the fairways. Now we will turn our focus to removing the existing weeds. The next available dry, calm day we will begin the chemical application. This application is difficult because the product must dry before golfers can walk through it or carts can drive through it, otherwise it will track and kill the grass on the greens or in the rough. This makes the timing difficult because we have to restrict where golfers are while we are applying. When the next acceptable day arrives, we will be closing the front or back 9 for a couple of hours. For example, we will ask all golfers to tee off #1 tee only while we spray the back 9. As the groups make the turn they will be able to play the back 9. Then, another day, we will ask all players to tee off #10 tee only while we spray the front 9. Again, as the groups make the turn they will be allowed to play the front 9. This ensures that at each time we have at least 2 hours without golfers on the 9 holes we are working on and gives the chemical time to dry so we do not have any collateral damage.

The upcoming spray is the final step in our program, but not the only step. How are we defending against weeds in the first place? How does this upcoming application fit into our overall program? While we may never attain a 100% weed free Bermuda grass stand year round, we continue to reach as close to weed-free as possible. We were not able to make our round-up application this winter. Between wet or snowy conditions, the timing was never right. Making the round-up application eliminates any visible weeds that infest the fairways over the winter and is our first shot at heading into spring with fewer weeds. You can read more about the benefit of this round-up application here. Once we clear those plants out, we apply our pre-emergent weed control in the spring, which stops any new weeds from growing. Finally, our last tactic is to make a post-emergence weed control application. This application removes any weeds that germinated after the round-up, but before the pre-emergent control. Once we are finished with this process, the Bermuda grass is free to grow without competition.

Any fairway grass is susceptible to weeds and a weed control program must be in place. However, with the Bermuda grass being brown and dormant, our weeds stick out much more obtrusively. We do have a plan in place and we continue to tweak it each year to eliminate as many weeds as possible. We despise looking at the weeds as much as the golfers and we are determined to continue fighting for perfection.

Annual bluegrass weevil and plant indicators

There are many different pests that attack turf grass and insects can be some of the most damaging pests we face. Because of the predominance of annual bluegrass on our course, the annual bluegrass weevil can be the most damaging of all. This insect attacks annual bluegrass from early April to the end of September and can cause irreparable damage in a short period of time.

Larva and pupa in the soil

The annual bluegrass weevil is a small insect that can be very difficult to find. The adult is only 1/8” of an inch long and moves mostly at night. The female lays eggs inside the stem of the annual bluegrass plant in the spring; the eggs hatch and spend several days inside the stem, and then eat their way out. Once outside the plant, the larvae, about the size of a small grain of rice, begin to feed on the crown and roots of the plant. This is the most damaging time in the life cycle. Any insect eating the roots and crown of a plant will very quickly kill that plant. Within about 14 days the larvae mature through adolescent stages and become adults. The females lay eggs and the whole cycle starts again.

Larva in the soil

The battle against this pest has become more and more difficult each year. The volume of annual bluegrass weevils has increased, their appetite has adjusted to include bent grass instead of solely annual bluegrass, and the amount of generations per year has slowly changed as well. The generational increase has become the most difficult aspect of managing the weevil. Early on in the management of the annual bluegrass weevil, there were only 2-3 generations per year. The adults that appeared first in spring would lay their eggs and the cycle would repeat 2 more times. We could time our control with these generations and attain good control. However, lately, the first eggs laid in spring mature at different rates. The next wave of adults lay eggs at different times and quickly the generations are no longer in sync. We may see 5-7 generations per year and at any point there may be adults, eggs, larvae and pupae. This is especially troublesome because the insecticides that we use to target this pest specifically, only work against larvae. So at any point, if only ¼ of the total population is in this stage, we are never achieving more than 25% control. Once the population is in this state of imbalance, control is difficult and we are simply trying to manage as best as possible.

The yellow-orange areas are damaged plants

More damage

Half green half gold forsythia

We do have one very important weapon that we use to help us against the weevil. We observe forsythia bushes as plant phenological indicators. This process relies on monitoring forsythia and timing our chemical applications based on where the plant is in its flowering cycle. Since the annual bluegrass weevil and the forsythia rely on warming spring weather to start emerging and blooming, we watch the forsythia because it is much easier to see. When the forsythias are half green and half gold, we make our application. Research has repeatedly shown this is when the most adults are concentrated on the turf grass we want to protect. By striking this initial blow to the population of weevils, we set ourselves up for a much more manageable season. The beauty of using forsythia blooms to our advantage is that it is reliable and site specific. Forsythias are a very hardy plant and we can count on them to perform year after year no matter how strong the winter was. It is also useful to know what is happening here at Bretton Woods. As you travel around the area you may see forsythias in several stages of blooming all at the same time. By watching the forsythias on the property we are in tune with what our temperatures have been doing and how our site is reacting to the spring, which relates very well to how the weevils are reacting to the weather as well.

We have several other tools we use against the annual bluegrass weevil, including soap flushes, pit-traps, and vacuums, but nothing has proven as reliable or as easy as monitoring our plant indicators. Nature has a way of keeping everything in order, we just have to learn the cycle and us it to our advantage.

Spring projects

March 4th!

Spring hasn’t officially started yet but it would be hard to know that based on the weather. The warm temperatures have sent the Grounds department into a flurry of projects. Here is a quick update on all of the things that are currently going on and those that will be starting shortly.

We completed aeration of greens the first week of March and the greens are healing well. We were able to get 1 week of pure healing time ahead of our first seed head suppression chemical application. Here you can read more about how that 1 week can mean a lot to the condition of the greens as spring progresses.

If you have been to the club this week you have seen the excavation of one of the grass areas out behind the clubhouse. This is the site of a new patio that we are having built. While the masonry work is being done by professionals, the Grounds department has been handling all of the excavation work and site preparation. The patio floor will be pavers that are similar to the bench pads on the course and at the DR tee. Also, a stone wall that matches several locations around the club will be built around 2/3 of the patio perimeter. Not only will the new patio be functional and provide an amazing venue, but the design and materials will also match other aspects of the property.

Cutting the cement pad at the DR tee

Another project that will be starting soon is the renovation of the DR tee mat hitting surface. Instead of individual hitting mats, a new, continuous mat will be laid across the entire cement pad. We are again hiring professionals to do the detailed work; however, the Grounds department will be actively involved with this project as well. The cement has already been cut to fit the new mat exactly. Once the excess cement has been removed, we will help in back-filling with soil, and re-sodding a large portion of the back side of the DR tee pad. When finished, the hitting area as well as the surrounding sod will be new.

We are also trying to balance these projects with our duties on the course. We are still working to complete our cleanup from the tree trimming over the winter. Any available labor and time is being directed to stick cleanup. We anticipate this being finished by the end of the week or the start of the next. The weather has also necessitated the start of our pre-emergent weed control program. This consists of protecting the tees, fairways, rough, green surrounds, soccer, and several other select areas around the property from common weeds such as crabgrass. Timing is critical to this process and missing the window can lead to weed-related issues all year.

Bermuda grass emerging on #12 fairway

Bermuda grass emerging on #10 fairway

One final note, in relation to the warm weather, has to do with the fairways. We have seen the first emergence of Bermuda grass already this year. Currently we are about 20 days ahead of last year in terms of accumulated growing degree days as well as visible green-up. This is a great start. We cannot make any rash judgments regarding when full dormancy will break, but starting this early does bode well for spring and beyond.

As a side note, we have purchased new trash/recycling combination units for the golf course this year. They are currently in production and we will put them out as soon as possible. Until then, please bear with us and use the trash cans at the water cooler stations. Thank you
