Aeration, Germination, Hibernation, Foundation

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.
