Its been a while since I've made a blog post. I'm making daily posts regarding course opening, carts and practice range restrictions or lack thereof on social media. Allow me a few moments to expand upon the work we have completed this fall so far and what there is to come.
We attempted to delay any aeration of main playing sources until we've gotten through most of our calendar of events in September and October. We began the aeration work around our greens using a 1/2" coring tine after slit seeding fescue around the greens to improve our coverage of turf grass. Our process included slit seeding, then aerating, spreading seed with a rotary spreader and then dragging in the material to make good soil contact and mowing. We should get seed germinating in the areas over the next couple of weeks and will then mature in the spring. We plan on using our rough aerator that makes a little bit larger hole a further out on the green surrounds over the next week or two which will improve its overall health as well.
We will begin to use our pull behind rough aerator in our rough soon as time and weather permits. Cores or plugs are pulled and we use a metal drag to break them up. This assists in reducing compaction and helps with stimulating new growth in our rough plants.

Greens aeration will begin on Monday, November 1st. Depending upon conditions for the first day, it might take us a 2nd day or so to finish up the last few greens. We will use our deep tine verti-drain aerator and go about 7-8" deep. The holes will be filled with sand and surfaces brushed to smooth them
out.

Our warm season turf grass zoysia was fertilized with potassium in September to assist it with winter hardiness. It thickens the cell walls and improves water and energy uptake. As zoysia goes into dormancy, it is storing energy which assists it in fighting off excessive cold temperatures.
We applied fertilizer to our cool season rough grass in the past couple weeks which will assist in providing new energy for our turf. As temperatures begin to fall, it utilizes less energy and begins to store energy for the next season. Once cold temperatures arrive in late November and early December it goes into a form of dormancy even though it is fairly green. The stored energy then allows the plant to green up a little earlier than non-fertilized turf.
A couple of weeks ago, I asked our contracted tree expert Tim Gamma to come out on property and assist me in evaluating trees that have been damaged by the gall over the past year or two that should be removed. There are 35-40 trees that were identified for removal in which 21 are Pin Oaks. There are a few Ash, Siberian Elms and Maples in which some were damaged by this summer storms and or have been scheduled for removal over the past year which make up the total number of trees. Some of these trees will be removed completely by our staff but others will require assistance from our contractor. They will top them leaving a stub and we remove the large limbs that can't be chipped and the log. Our budget does not have the funds in it to remove all the trees. GM Tim Grossman and the Board are working through the finances to determine the number of trees we can remove with the available finances.
We made our last mowing early last week on our zoysia tees, approaches and fairways. They might grow slightly over the next week or two and will then go into dormancy as our temperatures get cold enough for frost. We have also made our large patch zoysia fungicide application over the past few weeks to reduce the effects of the disease. The fall application of the fungicide assists in reducing the severity of the disease in the spring but we also must make another application in the spring to keep the disease under complete control.
Thanks again to the Foundation for the recognition of the work accomplished over the years here at Glen Echo by our staff.
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.
Happy Father's Day. My Dad has been gone for 28 years now. A great deal of life has occurred since he went to be with our Lord. Follow the best I can with the lessons he taught me daily on how to live a full life. Sharing your time and treasure to lift up people was one trait he shared regularly. The last day of his life he spent a day in a small town trying to build a new Kiwanis Club that would share in the giving he believed in so much. Its an honor to be your son!
A busy couple of months on the golf course as we barge head first into summer. Allow me a few moments to summarize our work.
Our new zoysia tee and surround areas are trying to establish themselves and mature. Some a little better than others but we moved into some warm weather conditions that will help push it along. Teeing ground turf will be a little slower to respond because of its concentrated wear from teeing it up but we will continue to encourage its maturity. Will begin some sand topdressing to help smooth out the surfaces and help them fill in.
We sprayed the weed contamination on the surround on 5 and 6 where the turf is established. We also sprayed some bermuda encroachment in these areas as well. Speaking of bermuda eradication, we will begin our fairway applications in the next few days as weather allows. Please see the video below for further explanation.
6 Green surround continues to improve. Weed control applied and we've opened the right side bunkers for play.
Fairways and tees were aerated last. We still have a few tees left including the ranges, the approaches and close green surround zoysia areas. We will do this work as weather and time allows over the next week or two.
We also Vented the greens using a very thin 5/16 needle tine. We also double topdressed the greens over a 5 day period last week.
Why vent the greens? You just aerated them at the end of March twice. Venting is a process that is used because it reduces surface disturbance but improves performance of our root growing area in the plants.
It improves gas exchange. Oxygen in and carbon dioxide out which can build up over time in the root zone.
Allows water to penetrate in hard to wet areas and can dry wet areas more quickly with air entering the subsurface.
The surface closes rather quickly but the small channels into the green surface going down 4-5" allow for roots to improve and thrive. Research has shown that these small pathways can be effective up to 3 weeks.
The lack of basic infrastructure in our greens(no drainage systems) places puts us at a disadvantage when it comes to dealing with adverse conditions including high heat and heavy moisture. This regular program allows our greens to combat some of the problems we face.
As you will see in the video below, there are 48 venting tines on the machine. Our greens average about 5,000 sq ft. Thats about 145,000 vents into each green assisting approximately 142,000,000 million bent grass and poa plants to survive. Approximately 1,500 plants per sq foot.
We have not been walking mowing our greens but plan on getting that started this week. We have 3 new staff members for the summer who we will begin to train along with our experienced group to incorporate this into our program for the summer to improve green conditioning.
Thanks for your time and I will try to get back to posting some additional work on the blog in the upcoming weeks ahead.
Not much of a zombie guy but the staff has been getting that sod zombie strut going pretty good the last couple of weeks. They laid another 500 yards on holes 5 left rough to finish the bunker surround area. 7 back right bunker entrance, 2, 11, and 15 approach's and the east side of the practice green area were all sodded. Also a couple of stump holes were covered up and some repair on 4 approach. Pulled up some good bent grass on the approaches and laid it on damaged collars. Normally when we have cut off larger areas for repair, we've used a tractor with a blade and the backhoe as well as a dump truck but its been too soft and the areas are pretty sensitive for large equipment. All these areas were hand picked up. We were able to place the sod nearby this week after our backhoe repaired which kept them from having to load into carts and then unload onto the ground. Staff did a killer job on all of this work!
Left collar on #11 repaired.
Right collar repair 11.

15 complete
We had completed part of the practice green area near the pro shop and looked at the Pearson Lane side and had to clean it up as well. Aerified it heavily and then put a couple yards of compost in place to help soil structure a little.
Guys laying the sod on practice area.
Its been mentioned could we place some zoysia around so you can practice approach bump and runs so we did a decent sized strip on the east side of the practice green. Not really a place to be chunking out areas of sod but should be able to practice and few bump and runs. We might have to close sections of this during the season when play has worn it down a bit.
We also put some entrance and exit areas on the pro shop side to try to spread the walk on and off area. We hope the soil modification, irrigation and aerating we will be doing will help keep this area looking good as well.
From the pro shop walk way. Did a larger cut out of zoysia neared Doc Ott's clock area.
Finished the area between the bunkers. Still have to repair the sod trench line from new irrigation.
Another look on 5.

The mowing of greens are becoming more regular along with rolling. The first mowing of rough, tees, tee surrounds, fairways occurred this week and bunkers were trimmed up. Finishing up on our pre-emergent applications and we do have a great deal of broad leaf weed control that will take place over the next couple of weeks. Dandelions, clover and some cool season weed control.
We did some finish grading around the new 2 tee complex. Trying to get our laser leveling contractor in over the next week. We are going to have to dig out part of the back tee. The soil is soft and pumping so we will dig it out this morning and put some good hard Glen Echo clay in its place. Little video below showing the smoothed out area.
Update on the repair to the back of the tee. Dug out a 10' x 12' section of the back of the tee this morning and back filled with some Glen Echo clay. The soil that was originally used was excessively wet and plastic like not allow the surface to firm and ultimately would have settled. The new soil should improve the situation.
Skip dug out about 2' of fill that ended up being too plastic/rubbery.
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.
View from the front of the tee complex. Tees are now set up as 2 separate tee boxes.
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.
