Sod Nursery Project

Last Thursday we completed the greens portion of the sod nursery over by the maintenance facility. There are many steps and hard work that go into building a sod nursery. Here are some of the steps we have been working on in the past couple of weeks.

1. Leveled the sub grade with a bulldozer.
2. Removed large rocks.
3. Installed irrigation to the nursery which consisted of 600+ feet of pipe, several sprinklers, electrical wire and fittings to hold everything in place.
4. Added 3-4” of sandy loam mixture over the sub grade to the greens portion of the sod nursery. Presently our greens on the course have 3-4” of sand in the upper portion of its profile, we replicated that scenario on our nursery by adding this mix so that it matches perfectly with the greens on the golf course.
5. We compacted the sand and leveled it smooth.
6. Next we seeded the surface with an improved variety of bentgrass and added a starter fertilizer.
7. After seeding we used our sand pro rake with its knobby tires to make small dimples in the sand. This allows for a good place for the seed to germinate because these little dimples hold water and do not allow the seed to blow away or run off.
8. Over seeded the area again with an improved variety of bentgrass.
9. We covered the surface with our permeable greens covers to incubate the seedbed in cooler weather.
10. We have been watering the nursery light and frequently since seeding and covering the surface.

There is still some work to do before we seed the fairway and rough portion of the nursery. We have to level the surface and in some areas remove some small rock before we seed this portion of the nursery. Once completed we will have 13,000 square feet of greens sod, 7,000 square feet of collar/fairway sod and approximately 3,000 square feet of rough sod.  We hope to see some germination in the next month.

Thanks to all who played in the fall fling and supported this great long term investment!

Stay tuned for updates and pictures of this project.

Course Update 08/29/13

The big story the last couple of weeks has been the heat and humidity.  Overall the golf course has handled the heat very well.  The greens and tees are in very good shape.  The fairways are a little stressed particularly on holes and in areas where large trees are depriving fairway turf of much needed water.  We have been watering a lot however, we have to be careful to avoid disease (which tends to thrive on leaf wetness) and soaking low areas that are not drying out in this humidity.  Once the heat subsides and humidity normalizes the fairways will look much better.

We have been working on some smaller projects and have a couple of updates:

Deep-Needle Tine Update

The greens have healed in nicely from the deep needle-tining that took place on Monday.  The greens are smooth and very few tine holes are visible.   I will update the blog showing the root development within these channels in the upcoming weeks.

 Core aeration of trenches

Tuesday morning we core aerated greens where trenches are located on #4, #9, #12, and #17.  We cored aerated these areas to help level and blend in the sod and plugs.  After we removed the cores we sand topdressed, brushed out the excess sand and over seeded.  These areas are small but we will try to keep the hole locations on these greens far enough away so that it has minimal impact on play.

A couple days after deep-tining and no holes!

Sod nursery

This week we have be working near the maintenance facility on the new sod nursery.  Last week the area was rough shaped and the past few days we have been diligently working on fine shaping the sub grade.   The important thing is to remove as many large rocks as possible and smooth out the surface.  To best achieve this we are using a Harley rake to perfect the sub grade.

Early next week we will be installing the irrigation for the nursery.  And next Thursday and Friday we will be adding 90% sand and 10% soil mix to the top 3” to achieve the same soil structure as what is currently on our putting surfaces.   Once the 90/10 mix is leveled  we will be ready for seeding and growing the nursery.

Cart Path Expansion

Last week we added some crushed asphalt to #5/13 tee area.  This area receives a lot of cart traffic and felt it was a good area to expand.   5/13 cart path and the newly added cart path on #13 green need to be leveled, tamped and then seal coated.  We had some issues with our vibratory tamper and are looking to correct 5/13 tee to make it as presentable as #13 green cart path.

Have a great holiday weekend!  

Deep needle-tine aeration

Today we will be deep needle-tining our putting surfaces.  This process is one that we do several times a season, the last of which was in mid-May. It uses long solid tines to poke small holes into the soil.  This process is not core aeration where lots of soil is removed and picked up.  Deep needle tine aeration is minimally invasive and has very little impact on play when compared with tradition core aeration or standard deep-tining.  Heal in time after core aeration and standard deep-tine aeration is anywhere from 10-14 days whereas deep needle-tining is healed within a couple days.  

As far as playability goes the greens will be a bit slower and may be a little bumpy early in the week.  As the week progresses, the bumpiness will subside although some small holes may still be visible.   

It is important to understand that there are many types of aeration and that all of them are critically important for having healthy turf on golf courses.   We utilize all types of aeration at Ridgeway but use deep needle-tining as our preferred method on greens.  The reason we chose this method more often than others is because we are able to do it 5-7 times a season without impacting the playability of our putting surfaces.  Since going to deep needle-tining we have seen our roots double in length and increase in mass.  This has translated in healthier more robust turf for the long term.

If you have any questions about aeration or any questions about the course in general feel free to email me anytime. Cheers!

It’s been awhile!

My lack of posting the past few weeks is not for a lack of activity on the golf course, quite the opposite, as we have been very busy nickel and diming little projects on the course.  Here is an update on some of the items we have tackled in the past few weeks:

• We added drainage to the wet area behind #13 green.  So far after a couple of storms the area drains perfectly.
• Added cart park area near the new drainage on #13, enhancing the overall function and aesthetics of the cart path.
• Added sod to numerous bare areas i.e. Area near #12 ladies tee.
• Removed stone and under brush near the parking lot landscaping and added mulch.
• Added copper sulfate and biological controls to lessen the amount of algae in the pond on #5.
• Removed pesky weeds in #13 native area.
• Removed suckers and low hanging branches on the course which includes the two large suckers near the pond on #13.
• Aerated newly sodded areas and raised the height of cut.  We did not fill in the holes with sand to allow for less scalping in these areas.

In the upcoming weeks we will be busy with a number of other items:

• Pruning dead and hanging wood from trees on the course. Also pruning overhanging branches on holes like #4, #11 and #18.
• Fill in soil around the new septic mound and planting native grasses which will hide the electrical boxes and other components.
• Fix a few of the faulty irrigation heads on the course.
• Prune areas around cart paths i.e. #14 green to #15 tee box.
• Core aerate, topdress and seed trench areas on August 26^th. Because these areas are small they should have little effect on play.
• Deep-needle tine and topdress all putting surfaces on August 26^th.
• Paint the trellis by the range tee.
• Work on the new sod nursery by the maintenance facility.

Must see TV!

This short segment was aired on the golf channel last week.  It is a great piece about conservation by using less water and increasing the amount natural areas on golf courses.  In the 21st century, with an excess of golf courses and fewer golfers this proactive approach can have a great impact on golf course finances going forward.  The combination of environmental stewardship and fiscal responsibility is something we can all get behind.

Wind damage

Last night a powerful storm littered the course with small sticks and large branches.  We will be diligently working to get the course cleaned up today.  It will be noisy on the course with the sound of blowers and chainsaws.  Please be patient while we cleanup the course. Thanks!

Bunker Sand & Verticutting

Bunker Sand

This past week we added some sand to many of our bunkers.  A number of bunkers have become much to hard and sand was needed to make them more playable.  Sand exits bunkers many different ways from players hitting shots, through drain tiles located underneath bunkers and from wind blowing sand out of bunkers.  We added sand to the chipping bunker, #1, #6, #7, #8, #11, and #17.  Earlier in the season we added sand to #2 greenside bunkers and the front bunkers on #13.

Keep in mind that this new sand will be soft until it ages. Sand gets a firmer once we have a few rain storms to settle and pack the sand into place. Expect a few plugged lies in the meantime.

Verticutting

Verticutting is essentially de-thatching or vertical mowing.  This week we verticut tees and greens in two directions.  Because our greens are now predominately bentgrass we will have to verticut more often in order to make the putting surfaces smoother.  Bentgrass has a prostrate growing habit which can influence leaf resistance causing the greens to putt slower.  By verticutting we remove excess tissue and stand the bentgrass up to make a smoother putting surface.

Here are some benefits of verticutting:

• Removal of thatch.
• Increase green speed
• Encourage grass to stand up straighter, making for a smoother putting surface.
• Improve effectiveness of  sand topdressing
• Increase sunlight exposure to roots

The first picture is of a green after being verticut 2x, mowed and then rolled.  As you can see it has no evidence that anything was done.  This is because there is very little thatch in our greens.  This process on greens was done to improve ball roll and smoothness. The plant will look more upright and many of the long strands of grass will be cut resulting in better putting surfaces.

The second picture is of a tee that was verticut 2x, mowed and topdressed.   You will notice some browning and thinning of the overall turf stand.  Our tees unlike greens have too much thatch and we removed a good amount this week, hence the browning/thinning.  Thatch is detrimental to turf because it harbors disease, insects, impedes root development, restricts air movement within the soil and bridges rain water/ irrigation from reaching the soil causing localized try spots. 

When playing the next couple of days you will NOT notice the greens putting any differently in fact they might putt better.  Tees however will look brown and thin in some spots because we thinned out excess thatch in some areas.  This is not a bad thing but a very good thing. Thanks.
