Fruit of our Labor

We are seeing results of our aerification and slit seeding along with signs that more needs to be done.

Pictured below are the rows of new rye grass that have germinated on 9 fairway. We have completed 7 fairways to date and plan on doing 3 more at a minimum. Unfortunately the weather forecast for seed germination is not promising!  Rye grass seed needs temperatures between 68 and 86 to germinate so lets keep our fingers crossed that “normal” fall weather prevails.

While mowing greens over the weekend, I noticed how green the aeration holes on the right side of 15 green have become. These holes were made last month when we aerated collars ( the slope of the collar is to severe for the aerator so we have to aerate part of the green in that section) This is a great  indicator for additional aerification.  Air entering the aerification holes stimulates new growth of leaves and roots. Very beneficial after the long stretch of wet, humid weather we have recently encountered.

The plan is to aerate #2, 15 & 16 greens again using the small 1/4″ diameter tines before November’s drill and fill aeration. These 3 greens have responded nicely from the August aerification but are not fully healed. We are going to add the back of 3 green and 7 green to the list  as the late season weather has caused them to thin. I also noticed wear from mowing the clean up pass on the circumference of most greens, which is normal especially giving the weather. Aerification will relieve these areas of stress.

Looking at the weather forecast for the rest of the week, tomorrow looks to be the best day to perform this. We’ll do our best to keep disruption to a minimum. The clean up process is quicker with small cores. We will need to be careful with the topdressing procedure as aggressive brushing can cause damage to the putting surface.

As a reminder, greens drill n fill is scheduled for Wednesday November 7 and Thursday November 8. This process makes the greens unplayable for most of the day. Please keep this mind if you plan on playing either of those days.

Sunny Days Ahead.

The forecast for the next four days looks promising for some long overdue aerification and over seeding. Of course we’ll take Thursday off for the McQuiston Open, but we’ll utilize most of the daylight hours on the other days to get as much new seed into the ground as possible as the window for germination is quickly closing in on us.

We will be focusing on fairways , approaches and some tees. The fairways will be slit seeded using the equipment pictured below. Its not as disruptive as aerification but it will bring soil to the surface that will need to dry out before we can drag it along with the seed into the grooves.

The 6th tees will be aerated as the sod that was installed in June is creating a barrier for water to infiltrate the tees. We’ll be using a smaller tine than usual, between 1/2″ to open up the sod and allow topdressing, seed and fertilizer in. We are doing the lower tee today and then the upper tee on Wednesday.

The Green Committee approved removing the Bermudagrass that has encroached into the approaches through select spot spraying.

We are also eradicating clover and other weeds from the approaches. But the troublesome Bermudagrass covers much more area on # 10 & 12 approaches than the clover.

Both the Bermuda and clover may require multiple herbicide applications, even into the spring of next year to remove them from the approaches. Aeration, seeding and topdressing will be completed in conjunction with the herbicide treatments to provide a seamless transformation between the weeds and turf.

One last note on aeration, drill n fill on greens is scheduled for November 7 & 8. Most of the greens are unplayable through out the process so please plan accordingly. I’ll be sending out reminders in the upcoming weeks.
