Golf Course Renovation: Week 5

This week began with some very nice sunny weather, and the team was able to mow greens and fairways for the first time since seeding.  Greens were mowed 14 days after seeding and fairways were mowed 21 days after seeding, which is fairly typical of newly seeded bentgrass.  With the unseasonably cold and wet weather this weekend, staff spent yesterday covering greens, and the covers will likely remain on for several days until the chance of frost has diminished.  It appears that we will get a bit of a warm-up later this coming week.  Some warmer temperatures and sunshine will be good for the turf.

Pond bank stabilization in full swing.  Installation of coconut husk logs has been completed on #12 fairway, #12 approach, and #4 has begun.  Staff will continue to work only on installation of logs until later this fall when sod can be laid without requiring large amounts of hand watering.

Mowing #10 Green on Tuesday afternoon.

Most fairways are filling in well.  First application of Velocity to kill Poa is next week.

38 degrees??  Green covers will eliminate chances of frost and encourage continued growth.

Golf Course Renovation Week 4

Week 4 of the golf course renovation project went quickly with the holiday on Monday.  Our primary objective was to sod green perimeters, and each day Tuesday, Wednesday, and Thursday one semi load of sod (9,600 square feet) was laid.  By Wednesday, the golf course had dried down enough to apply fertilizer with the spread truck on fairways.  The fairways are filling in very quickly, largely due to utilizing the correct equipment and correct set-up by our equipment technician.  

The rain on Friday threw a wrench in our weekend plans.  After receiving 1" of precipitation in about twenty minutes, an inspection of the golf course revealed wash-outs on many of our putting surfaces.  Today, the staff spend a good portion of the day repairing and reseeding these areas.

Golf Course Renovation Week 3

Week number three of the golf course renovation was all about the grass.  The fairways, which were seeded last week, have germinated and are growing very well.  On sunny, windy days they require a moderate amount of attention, but not nearly the amount of attention as a sand based green.  All greens were seeded this week, including #1 Green as its reconstruction was completed on Wednesday.  A total of 3200 pounds of bentgrass seed has been planted on schedule.  Although it may seem early, it is likely that staff will begin mowing by the end of next week.

We hope we don't need to use it, but it is best to be prepared.

Golf Course Renovation Week 2

The golf course has taken on a different look this week with the appearance of dead fairways and greens. The construction of #1 Green is nearing completion.  On Monday, Chris Cochran with Nicklaus Design was on site to rework and approve the sub-grade, which gave our construction contractor the remainder of the week to install drainage, gravel and sand mix.  Chris will return on Monday for final inspection and approval of #1 Green, and we anticipate seeding to occur on schedule next week.  

Fairway seeding was completed on Wednesday, and we will expect to see germination some time in the next couple of days.  The warmth, rain, and humid conditions will expedite germination.  However, these conditions have warranted precautionary and preventative treatments for the fungal pathogen Pythium, which thrives in conditions like this and can quickly destroy young, succulent plants.

Golf Course Renovation Week 1

The first week of closure to play has been very productive.  Our primary objective as we begin working on the golf course is to plant seed in the fairways and on the greens because the opening date next year will depend on the maturity of these two surfaces.  With some great weather, we have been able to keep a tight schedule, and to date there have been 4 acres of green prepped and sterilized, 36 acres of fairway/step-cut sprayed with roundup, and all approved tree removals around greens have been completed.  Our construction contractor is on schedule with the reconstruction of #1 green, and Nicklaus Design will be on site tomorrow to approve sub-grade.  We expect #1 green to be ready for seed on August 25 along with the rest of the greens.

Approach Drainage #9

Prior to re-grassing fairways and approaches this fall, staff is utilizing a closed Monday to install drainage throughout problematic areas in #9 approach.  Typically, we aim to install about 500 linear feet of perforated drain tile in problematic areas, and each year we have seen incremental improvements in their drainage as well as a significant reduction in winter kill from ice damage.

Normally, projects that are "in play" are handled in the shoulder seasons when the golf season is not in full swing.  We have elected to perform projects scheduled for late fall throughout the next two weeks due to the fairway renovation that will begin on August 11.  This will allow staff to focus on growth of the new turf without disturbing it and complete the projects that have been scheduled this calendar year.  It will also result in firmer playing conditions in the approach.

Trial Putting Green Update

As part of our bentgrass variety trial on the Putting Green, root mass samples are being taken on a monthly basis.  The depth of the root mass is important to us for a variety of reasons.  Some of the more obvious reasons for desiring a deep root mass relate to playing condition.  Less watering will equals firmer greens, less ball marks, and truer surfaces after being mowed or rolled.

From an agronomic standpoint, the benefits of a deep root mass are far reaching, especially with poor irrigation water quality.  Effluent water is the culprit of a plethora of issues associated with intensely maintained turf.  Excessive algae growth is common on greens, causing turf to thin and leaving voids for Poa annua to invade.  Black Layer, is also a very common cause of turf decline on sand based surfaces that are irrigated with effluent water.  It is caused by a colonization of sulphur reducing bacteria which release toxic gasses and create anaerobic (lack of oxygen) conditions in the soil.  Shade exacerbates each of these issues.

We have estimated that our water usage on the Putting Green has reduced by 85% since being re-grassed to bentgrass, and, due to this substantial reduction, black layer and algae blooms have been eliminated as issues to this point.  This has been made possible by the deep and dense root system of the bentgrass, and the growth of that root system was made possible by proper aeration and proper amounts of sunlight/air movement.

There are a couple of varieties on the Putting Green which have separated themselves from the pack with respect to rooting, which will weigh heavily in our decision making process for the grass type(s) chosen for the greens renovation this fall.  Seeing these thing on the ground and not only on sell sheets provided by seed manufactures is both exciting and impressive.
