Winter Maintenance For Irrigation System

Once again it is that time of year to make sure last years water is out of the irrigation system in preparation for the long cold months ahead. The actual pump station has been shut down and winterized since the middle of November. This operation is completed by a contractor mechanic who specializes in maintaining the pump station.
However, the irrigation lines on the golf course and the valves that control the water flow thru these lines are winterized by the maintenance staff. We do this by pressurizing the system with high pressured air supplied by a compressor. Below are a couple of pictures explaining this process.



This is the compressor that is rented for the day to perform the blowout of residual water in the irrigation lines. All valves are opened so that air can freely flow throughout the lines pressurizing the system with air instead of water, so that irrigation heads can be activated to release the water within the lines.

The compressor's air hose is connected into a hose adapting port that is used for the retrieval of water during the season, but used to pump air into the lines this time of year during the blowout operation. When the lines are fully pressurized with air, the irrigation heads are manually turned on one hole at a time until water stops appearing from each individual head on each particular hole. This operation usually takes 8 hours to perform, by starting with the practice area, and then going #1 thru #18 with the activation of irrigation heads.

This is a picture i snapped this morning on December 13th, showing the scene at the clubhouse and practice green. This is just a reminder that winter is here, but hopefully this scene will not appear as many times as it did last year!

"Winter Work"

With Leave cleanup at a minimum now, and cold winter temperatures arriving early in December, our focus has turned to improving conditions for the 2011 season. Underbrushing of tree lines, limbing the lower branches on larger trees, and the removal of dead trees are on going. We have started with hole #11, because of where this operation concluded on #10 the previous winter. We will continue this for holes #12 thru #18 as mother nature and time permits. The pictures below show this work, as well as some detail cleanup we have completed with ornamental beds throughout the property.

The ornamental beds around the clubhouse area have been cleaned of leaves and debris, producing a clean appearance when arriving. The ornamental beds on the golf course are in the process of being completed as well.

All trees along the right side and behind #11 green have been limbed, producing a higher canopy so that air can move freely across the surface of the green.

We have started the underbrushing and limbing operations beginning with the right side of #11. Our goal is to improve the air movement for the turf in the fairway, as well as improve the overall aesthetics of the hole.

New Cart Path Exit Regulations

Our goal is to provide an easy reference point for golfers to know to exit the fairway and improve safety by eliminating many ropes on the course. This system is more visual; however, we must rely on all golfers to follow these regulations to insure peak playability.

Ropes on the ground have been added to mark the exit point for golf carts on the fairway. Exit signs can be found on either side of the fairway too.

Please do not drive beyond, through, or around white stakes. Carts approaching the stakes should exit the fairway at that point.

Follow the rope and signs to the fairway exit point. Then drive around stake nearest the path.

Spring Improvements and Enhancements

The finished look here on hole #12 shows what the new sand does for the contrast of color between turf and sand. It definitely has changed the overall appearance of the green complex.

New bunker sand has been added to greenside bunkers on the back nine. Playability will be an issue at first, but the sand will compact with time and weather.

Three newly planted trees to the left of the blue/white tee on #16 will give the tee shot from the back tee more character and separation from surrounding holes.

Trees were planted to the left of 13 tee to develop a tree line that will separate holes #13 and #16 in the years to come. The trees that separate the holes now are continuing to age, become diseased, and die. When those trees are removed in the coming years, the newly planted trees will become the new tree line.

Aerification, Top Dressing, and Fertilization

Due to Mother Nature's unwillingness to cooperate, the greens aerification scheduled for Monday March 29 has been pushed back to either Wednesday or Thursday the 31st of March and 1st of April. When the conditions of the greens dry down enough this is the process of what we will be doing.







We will be using a .4 inch diameter tine to punch the holes in the greens this time around. We are relieving the thatch layer of organic matter that has built up during the fall and winter months. These holes also allow the release of harmful CO2 gases that are trapped beneath the thatch layer, and allows oxygen into the soil to promote new root growth for the spring.

Using this diameter size of hole will allow for less interruption in the putting surface. With a good combination of sun, rain, and warmer temps the surface should be back to satisfactory conditions within 10 to 14 days.

After the cleanup of cores on the green from the aerifier, we will apply a topdressing of sand to fill the holes with new growing media for the plant and roots. This application of sand also helps smooth out any discrepancies in the surface for better putting conditions after the green has healed.

We also apply calcium, phosphorous, and potassium amendments while the surface of the green is open, so that these nutrients can enter into the root zone and be used by the plant to help produce a new and healthy root system. The sand and amendments are brushed into the holes. (A picture of the brushing procedure will follow up with this post in the coming days)

Goodbye "Old Man" Winter!

Spring time is upon us, it wont be long til trees and flowers on the course will be in full bloom. The slow melt of 40 plus inches during the months of February and March will play a huge role in the color of the turf u will see this spring. Natural Nitrogen levels in the soil are higer than normal due to large amounts of snow.

New Bridge Constructed On Hole #17

Construction of the bridge was completed on Wednesday March 10th, with the exception of a small amount of paving to the cart path on both sides. The paving will be completed next week. The bridge is passable at this time and was opened for play on Thursday March 11th. Below are pictures of the structure:
