Holey, Holey, Holey!!

Within the past 7 days, our staff have been to the beach and back a couple of times. No we were not on spring break but dealt with tons of sand. actually 71 tons of sand. Last Tuesday we posted the dryject work that was contracted out but our staff loaded the machines with 30 tons of sand. 

Yesterday, we connected our tractor to our Redexim Verti-drain deeptine aerator and put about 144 1/2" wide by 8" deep holes per square foot for a grand total of about 8,736,000 holes in our greens.(Yes I counted them all) The operation last week was about the same spacing so over 17,000,000 aeration holes in our greens the past 6 days. We still have 3 greens to finish, holes 16-18 and we hope to complete those on Wednesday.

Our operation included the following:

• Topdress the green with a heavy layer of sand
• Aerate the green
• Use our pull behind blower and backpack blowers to blow the sand in the holes
• Brush the remaining sand on the green surface to smooth them out.
• Roll the greens to help smoother over the holes

This operation should assist our early season green growth in the following ways:

• Allow moisture to enter surface more readily and assist wetter areas in drying more quickly.
• Increase oxygen into the green profile.
• Improve and increase root growth to combat summer stress
• Extra sand on the surface assists in smoothing the surfaces. Of course initially the surfaces are disrupted from the tugging and pulling of the aeration equipment. 
• Protects the crown area of the plant where roots and leaves begin their life.

It will take about a week of watering and rolling before we will mow the greens. This will allow the sand to settle and the turf to grow up through the sand canopy. The holes should be completely filled in within a couple of weeks. I anticipate the greens to back to normal around opening days for our members.

During the season, we will vent the greens with smaller tines about 3-4 times to assist in plant health. This is completed with a small 5/16" tine which goes into the surface of the green about 4-5 inches. It is usually non-disruptive to putting surfaces and the holes disappear in a couple of days but it is very important to plant health in the summer.

We will also do light and frequent topdressing which helps to smooth the surface and protect the crowns of the plants. It also improves ball roll out after a couple of days. A few videos below of the process as well as a couple of pics.

Holes filled. Might be a stray hole or two not filled but for the most part they are all filled with sand.

Summer's Almost Over and Fall's Coming and A Major Project Change

 Well, we've survived the meteorological summer(June-August) with a little less than 3 weeks before fall. Overall had a pretty good summer. I would have liked the greens to be a bit firmer but humid(wet) and hot conditions do not make it easy to produce that type of playing surfaces. No doubt they will get firmer and roll out will be great here in September/October.

Weather highlights for July/August

4th wettest July on record 9.07"

22 Days over 90 in July, normal is 12.

16th wettest summer(June-August) of all-time 16.49"

26th warmest summer on record.

So what have we been doing on the course the last month or so.

• Sliced, knife aerated the fairways

12 hubs, 16 blades on each hub for a total of 192 blades. Aerator is 6' wide. Blades go in about 2" deep and leave a cut about 3" long in the fairway. Normally in previous years the slits would turn a little brown due to less rainfall/drying on the edges but with our fairways being fairly moist when we did this work, they stayed green. 

• Deep solid tined the approaches and tees

There are 6 tine holders with 3, 1/2" tines and 2,  3/4" tines for a total of 30 holes every 3" as the aerator rolls along. We set the aerator to go about 4-5" in depth. This will assist in root growth and moisture penetration into the tees.

• Sprayed 2 applications of fairway, intermediate and zoysia green surround bermuda eradication chemical products. Fairways are not crispy, just slightly off color from the spray. The club spent $ 250,000 to put the zoysia down in 1995. We are trying to keep the bermuda grass out of the fairways. 

Other work completed included but not limited to the areas below.

• Needle tined greens at end of July

• Trimming fence lines trees, vines etc.

• Topdressing and brushing greens and tees with sand to improve ball roll out and smoothness

This was some of the major work accomplished over the last month or so. Of course there are many hours spent mowing, spraying and daily routine work that takes place as well.

The month of October we had scheduled a tee renovation project for #4/#12 tee complex. The Glen Echo Historical Foundation had raised money for this project through member donations and the Gala. 

There is a 3' drain pipe that takes the storm water from Glen Echo Park subdivision and sections of the course from #6 to the lake in front of 10 tee. One of our rough mowers ended up rest on top of one of the pipes near the edge of 8 fairway when a cave in occurred. The galvanized pipes running underground are completely compromised, rusted out in the bottom which is creating sink holes in various sections of the pipe. We have completed minor repairs over time but its finally time to repair this situation properly.

The project will be broken up into 4 sections. Three sections average about 100-130 feet and begin and end at large drain chambers where the pipes are encased in concrete. The longest run is from a drain we exposed in the left side of 8 fairway to the cart path in front of 7 tee. We intend to place some additional drainage in 8 fairway and to the right of 8 fairway which stays wet for a long period of time in the spring. We also intend to reshape the bottom of 8 to help direct water into the large basin. 

I'm evaluating a potential timeline and will discuss it in the future. We have not had a Green Committee meeting since this situation occurred so more details will be forthcoming. We intend to wait until at least mid November since we will have a great deal of work on the course to complete over the next couple of months and of course we want to give our members ample opportunity to play the course during the middle of fall.

Sand, Holes, More Sand, More Holes and Project Updates

During this most difficult time, your grounds staff is preparing the course for what we hope will be some normalcy in the future. Our seasonal/summer staff will not be added until our club is back in full operation. We are lucky that our staff on hand including managers has over 175 years experience in working courses with a majority of that being at Glen Echo.

As weather improves, we will be finishing the project that was started last fall which includes zoysia around the back of 5 green and grassing the 6th green complex with zoysia. This funding is provided through the foundation and has already been allocated for this project from 2019. We hope to have the tee open sometime around May 1st if the weather cooperates. I would expect to have the sod completed around the greens by May as well.

We had initially planned to renovate the 4th and 12th tee complex but under the current situation it was determined to postpone this project. We have not determined a new date but it will be no earlier than October 1st since member guest is at the end of September. 

This past Monday, the staff was involved with our contracting company @DryjectofTennessee to aerate our greens. Our spring process involves the Dry-ject system which shoots a stream of water and sand at 3,000 psi into our greens staring from the surface and ending about 5" into the existing sand profile

Out staff’s involvement was to load 5 gallon buckets of dry sand into the aeration machine hopper. We used about 30 tons of sand. That is too many buckets of sand to count over the 10 hour period the operation took to complete. We also brushed the greens once they dried and they were rolled the next day since we ran out of time.

Hopper area where kiln dried sand is dumped. Sand is released through the holes and is then injected down into the green.

Chad Gamble, owner operator. Been a tough season for his business with cancellations beginning to fill his phone from our existing health crisis.

We hope to do a deep tine aeration of our greens early next week. This will consist of the green being covered in sand and then a half inch tine will push through the green surface to about 8” of depth.Our greens do not have modern drainage and must drain through our 4-6" sand profile and through the holes that are filled with sand. Deep tine aeration has been a life savor for our greens assisting in water removal from surfaces. Modern green architecture consists of an elaborate drainage system consisting of 10-12" of sand, gravel and drain tile. Our 9th green is the only one on property with this type of system.

The staff have been replacing damaged heads around our greens. The new system has been in the ground now for 13 seasons. Mowers and equipment going over top of them break the outer top casing which can effect the way the head operates. Our mower can also catch the corner of the head and damage it further.

You can see this head is missing almost 1/2 of the top part of the casing which rests on the soil/sod surface.

Russ working on a head at the corner of 4 green. Jason was involved in this production as well. Hopefully will be finished today.

2 Tee Renovation and a Great Deal of Other Work to Discuss

March 22nd and 23rd we did the rough in of the new tees on #2. Due to the movement of a great deal of soil and wet conditions every 3-4 days, we are at a pause in work on this project.
I would hope if we can get dry in the next week or so we will get the surrounding area of the tee finished graded and prepared for sod. The teeing ground will be tilled and laser leveled by Schaefer-Meyer we hope within the next couple of weeks and then sodded so that the tee will be open for play by mid-May.

From behind the tee complex. Sorry for the poor pictures, just looks like a pile of dirt from this level. Had my drone in the air the other day to take pics and crashed into a tree. Once I finish the repair, I will give you an overhead view.

Being the largest group of maintenance folks on staff at Glen Echo, our crew has been assisting in other areas. We spent about 20 man hours power washing the pool wall both inside and out. Also power washed all the walk ways in the front of the building and a part of Pearson Plaza. The staff power washed some of Limestone window sills that we did not get completed last season. The staff  with some able bodied assistance have also been busy inside the pool area removing some over grown shrubbery and pruning others. We we were in the process of mulching the upper wall bed when our loader broke down earlier in the week. Once it is back up, we will finish the mulching of this area. 

We will also be power washing the swimming area of the pool and installing new drain lids and plastering in new frames for the pool system. We will be managing most of the mechanical start up of the pool this season. I attained my pool operator certification for the pool over the winter.

The staff have also been involved in stringing the patio lights and moving equipment to the patio since warm weather is on its way.

This week the staff have been extremely busy with sod work. Over 450 yards of old sod was removed and replaced with both fescue and zoysia. HATS OFF TO THE CREW THIS WEEK!! Our loader was broke down and we had to load the sod into carts and then unload it from the carts.  Normally we place the sod right in the area of work so double work for the guys this week because of the repairs taking place to our loader.

We first completed the tree removal stump repair and root removal on the old tree near 11 green. This was replaced with fescue.

Area to the right of 11 green. A large amount of roots had to be busted out by hand using axes and shovels.

                                                       The finished area off the front right of 11 green.

We then moved to #5 left bunker area. This area has a number of contributing factors to its look. Small area with a great deal of foot and equipment traffic. Last year we tried to resolve some of it with walk mowing the area. Significant shade and drought is the biggest reason for its decline. A large Pin Oak is growing right in the middle of this area and robs it of sunlight and much needed moisture. We stripped the old sod away, trenched in some new irrigation heads that will hit just in this area. We aerated it and put in a couple of yards of leaf compost. The area was then dragged with a metal drag to break of the dirt turds and move some of the compost into the holes. Sod was then added. Should see some improvement we hope with new sod and the other work we completed. We still have some additional areas to sod around the tree and bunker and will complete this hopefully next week.

Tree on the left is a beautiful specimen set back in the proper area on the hole. Tree on the right is being over shaded and basically is growing on one side. Leaves, acorns, and other material fall into the bunker regularly. The shade and moisture depletion is significant.

This is the trench that is about 15' deep and shows the network of tree roots from this tree.

Small 2-3" long turf roots have no chance in a competition for resources with these trees.

Aeration completed so that we can then add compost to improve the soil.

Compost added to the area.

After the area was dragged with a metal drag. Cores busted and some compost moved into holes.

Staff finishing up the sod work. You can still see the weakened turf around the tree. It will be replaced in a few days.

Complete

The staff worked on the 13th approach today and also did a smaller amount of work on the 18th approach. We removed the bent grass sod, repaired part of the collar on 13 and part of the collar on 16. They removed the rest of the material and then laid zoysia in its place. We also had some bermuda contamination and very weak turf in front of 18 approach which was pulled up and replaced.

Finshed area looks great. Still some weakness in front which we will work on improving with aeration, compost and traffic control from our mowing units.

Same Story Different Week With Course Being Closed and Winter Dormant Zoysia Spray

Well, sorry to be the bearer of bad news but conditions remain  frozen and or thawing here at Glen Echo. Just beginning to thaw today and I only give it a 1/10 of 1% chance of playing on Valentine's Day so I guess some would say there's a chance. Looks like snow and some colder temperatures over the next few days so golf looks like a no go for a bit longer.

We were out spraying some fairways, tees and approaches with our dormant herbicide spray. The turf must be dormant because we are spraying a non-selective product that injures and or kills green weeds and or grass. We are trying to kill any poa annua that has germinated on these surfaces and it also will kill any knot weed that has germinated. It appears the knot weed is still sleeping from the cold weather. If allowed to grow in the fairways during the spring, poa annua seeds profusely adding the more plants and can get rather clumpy before the fairway units beginning mowing. It also can invade more shaded areas and slow the health and progress of the zoysia Poa becomes active pretty quickly during warmer, sunny weather in the winter to early spring. A few days in a row over 45-50 and it becomes active. The plants will absorb the spray from the warmer weather as it becomes more active. Even if the temperatures turn cold, the chemistry is designed to stick on the leave of the plant and when it becomes active a few days later it will begin to kill the plant. The spray will show up over the next 2-3 weeks by yellowing the plants and will turn orange, brown and then die. Poa annua has a long growing period and reproduces millions of seeds. It loves moisture and shaded areas for the most part but will live in full sun is well so it is very adaptive.

We put a second product in the tank that helps to prevent crab grass and goose grass which germinate into the spring and summer. The product we utilize binds itself to the soil which allows it to be sprayed now and is on the soil surface when needed during April,  throughout the summer. Microbial activity begins to break down the product by the end of the summer but the zoysia is rather tight and keeps the soil surface shaded. Thinner areas of zoysia can develop some weed infestations because the soil is exposed to light and more moisture which can germinate weeds. We try to place enough product on the surfaces that will prevent weeds from germinating through August into September.

We were able to spray holes 1-7 today and the tees associated with those holes.

Below is a video with discussion regarding this spray application.

A Big Blast From the North and the Impending Thaw, How That Effects Golf Green Health

We've had above normal temperatures for the most part during the first 28 days of January with nights being well above normal and day temperatures a couple degrees above. This next blast of cold air the last four days of this month will bring our temperatures closer to average.

I'm sure everyone is anticipating the impending cold that will be followed by a warm up in the forecast below. I believe we have a 1 in 4 chance getting the course open this weekend.

Before we get too excited for a potential course opening this weekend, allow me a moment to discuss the yearly freeze/thaw issue that takes place with our greens.

We are getting to the time of year, probably a month or less before our first mowing of the winter/spring season. With cold temperatures like we will be experiencing over the next few days and no snow cover, the freeze is going to move pretty deep into our sand layer of our greens. The greens need to thaw at least 2-3" and the top of the green surface must be free of significant moisture.

Consequences of Greens Not Being Thawed Deep Enough

As the greens begin to thaw just an inch or two, the thawed part of the green can shift from golfers walking causing the area where the thaw and freeze meet to break or shear the roots off. Our roots this time of year are about 4" deep on average.  

Reducing the length of the roots forces the plant to regenerate new roots in the spring forcing it to catch up with non-damaged plants. Roots not damaged are growing deeper and branching more which  contributes to a healthier plant throughout the spring  and into the summer. The damaged plants see a total surface area of the roots reduced from this damage. The damaged plants must play catch up the rest of the spring and into the summer. If summer conditions arrive early like they did last year, there is less growth potential available for recovering plants and no storage of excess energy. 

The more total area of rooting the plant has, the more energy and moisture they can absorb throughout the spring and into the summer. Usually excess energy is produced and the plants can store some of this excess energy within the plant. The plants store this energy for use during the summer when growth slows and photosynthesis does not produce enough energy to maintain a healthy plant. The longer the plant has energy, the better it can ward off the severe stresses of our 

St. Louis summers. 

Consequences of Water Near the Surface

If the greens have not thawed deep enough to allow the moisture to move through the profile, the greens become spongy and very soft. During late winter play, if we allow play on greens that are very soft and spongy, foot traffic imprints into the surface of the green and may take a couple of weeks for it to come out. This condition can also contribute to large ball marks and damage from just walking on the green. There is also some potential for equipment potentially scalping the surface if this thaw occurs closer to the end of February. We always try to roll our greens in early spring in an effort to reduce the potential for scalping from puffiness and or foot imprinting.

The staff will be monitoring our surfaces and will alert the pro shop when play will be allowed on the golf course including the practice green. For those of you who like odds, I would place our chances of opening at 25%.

The staff has spent the last few days splitting wood, cleaning up tee markers, refurbishing some tables for Golf Pro Mike, cart maintenance, and checking out the internal workings of the ball washers. I've attached a few pictures of their work below.

Sanded and stained but not quite finished.

Shiny and new!

3 Tables in all were refurbished.

Beginning the coating process.

The walk on area from the pro shop to the practice green was renovated
this past fall. We prepared a little taller stake to attach our nylon rope which will
 allow us to rotate the entrance and exit area from the practice green. Proper
 water, soil structure, aeration, rotating the wear pattern and removing the large sweet
gum should  help improve this area tremendously.

Guts pulled out of the ball washers and being cleaned. Washers were professionally
repainted 4 years ago and look like new  to this day.

Frost, Turf Renovation and More

We experienced our first frost of the season today and it was heavy enough to create a slight delay. Be aware that this will occur more frequently as evening temperatures dip into the 30's and soil temperatures begin to cool. Excellent article on Frost Delays from the USGA and a video below. I'll give the Glen Echo Grounds Department's view on frost in the next week or two with another blog post.

Not good when your first hole is at a low point on the course

#10 as well

We have a number of turf renovations projects completed and taking place as I type these words. Over the years we have been replacing the false front approaches on the greens that are bent grass. We replaced #12 last week. It will sit dormant over the winter and will begin to grow in during spring. We intend to replace a number of other approaches next spring including 7, 10, 13 and 15. 

Guys finishing a corner of the intermediate near 12 green.

Single lap collar on #12. Saves club time in mowing, water since zoysia requires less water than bent grass and chemical applications.

Replacement of collar on practice green walk on.

Same area.

 As most of you have seen and can see from the pictures above, the practice green walk on area is not in great shape. We tore it out this morning and began the process of restoring this area.

• First thing we did was strip the existing sod to Doctor Ott's clock.
• Next we rented a large walk behind tiller and tilled the area as deep as it would go, 6-8 inches.
• Bought 2 yards of compost and tilled it in. Also added some bagged compost that we had stored.
• The next thing we will do over the next few days is to get some small irrigation heads installed that will only apply water to this area.
• Once that is completed we will purchase some new fescue sod and let it rest over winter
• We will install some human traffic control measures to spread the wear and tear. Provide proper cultural practices including multiple aeration over the season. Fertilizer and chemical controls will also be need to improve the overall health of this area as well.Pictures and video discussion of the work we are doing at this site.

  

  Working in the darkness of morning. Frost on the turf so we had this work to do.

  
  

  

  This is after sod was stripped. We do have mats for you to walk across the dirt area. After tilling below, the dirt is very soft and we don't want you tracking the dirt on your greens and into the pro shop.

Spraying Collars with Bermuda Contamination As Well As Some Fairways

Last week, Tom sprayed the collars that had bermuda contamination in various stages. We still must backpack spray areas that have zoysia next to them because the chemical is harmful to zoysia so we will do it very carefully with our small sprayer where bermuda has contaminated the collars next to zoysia.

This week the bermuda has turned white if you have been out to the course the past few days. The chemical used (Pylex) disturbs the cartenoid biosynthesis. Carotenoids serve two key roles in plants. They absorb light energy for use in photosynthesis, and they protect chlorophyll from photo damage. By turning white, the chemical is disrupting chlorophyll production in the plant. We are applying this product at 1/2 ounce per acre because it is being applied over the top of bentgrass. It can damage the bent so we are going with lower rates to offset injury to the bent. Standard use rates on more tolerant species are only 1 to 1.5 ounces per acre so as you can see a highly effective product at low dose rates. We must do 3 consecutive applications over about 1 1/2 months to kill the bermuda. Of course, you must then go after the bermuda that is outside the collar so it is an on going process.

Collar on 10 turning colors from green to white. Part of the plant is still green. Successive sprays should for the most part kill it.

This is a section a few feet away in the approach that was not sprayed.

I also sprayed 3 fairways with our fairway eradication product last week. You are beginning to see some changes in fairways 1-3 and a little on 18. The bermuda in these areas will turn a little reddish as the chemical works its way into the plant. I'll have pictures of this over the next few days as the chemical begins to do some damage to the bermuda. I need to spray other fairways but rain and high heat have gotten in the way. I'll probably spray them right before Echofest so it does not disrupt the color until after the event is over. We also must get these sprays completed before the zoyia grass goes dormant which could effect its ability coming out of dormancy next spring.
