CDGA Scouting Report - April 20, 2012

April 20, 2012 Scouting Report

Nice Temps, Needed Rain Arrives, 1st Crabgrass Seedlings, 1st Sod Webworm Injury, Poa annua Seedheads, Microdochium Patch, and Tim says Embark

Chicago/Northern Illinois Update: Derek Settle - DSettle@cdga.org/Weather Blog

As April's go, things feel pretty normal. Did I say that? Daytime temperatures felt comfortable with 60-70° highs and most nights felt chilly - as they should. Our lows were 30 something and most days, a light jacket would do. A more normal pace of temperature accumulation calmed us. Only once out of a span of seven days did we record frost in the north suburbs. Meanwhile, south suburbs saw not one. Nevertheless, new pests did arrive and reminded us that they do have early life this season. 1. Like our first crabgrass seedlings to appear (preemergents are needed earlier in 2012!). 2. Like sod webworm moths and their larvae which spelled the letter V on Sunshine's greens this week (v for victory?). 3. Like pink snow mold's reappearance which for obvious reasons has been renamed Microdochium patch (it's April and it isn't snowing!). 4. Like Poa annua, now shining flower-wise on most courses (Poa seedheads!). 5. Like a disease look-a-like or frost induced reddish creeping bentgrass (not leaf spot of bentgrass!).

Overall in the landscape, I noticed deciduous trees seemed to be leafing out all at once and a couple eye-poping woody ornamentals were done - lilac and crabapple flower gone. Otherwise, most things look really healthy as progression to 'all green' continues. Soon Mother Nature will say "Ta da!"

Have a nice weekend as we continue to enjoy cooler/normal temps.

Week in Review - April 20

This past week the greens continued to heal from aerification.  After aerification we raise the height of cut to help protect the mowers from the sand and gradually bring the height back down.  Today we have reached our normal height of cut but with the cooler weather the greens will take a bit longer to finish healing.

Frost - is it spring or fall?

Since Monday we have had a hard frost each morning.  The lows were:

April 9-12:
       Monday - 33.2
       Tuesday - 24.8
       Wednesday - 22.2
       Thursday - 23.7

Not exactly what we would like to see just after greens aerification.  The predicted rains and higher night temps over the weekend will help the recover process.  The frosts have been hard on the trees, shrubs and perennials that started to grow.  How much damage will be done, is hard to know at this time. Click pictures to enlarge.  All were taken today (Thur AM - April 12).

Spring Aerification

Today we were able to complete aerification and filling of the holes with sand on all 18 greens.  The putting green will be completed on Tuesday (when more sand arrives from Ohio).  We used ~50 tons of sand for the 18 greens.  We began aerification of the tees today and will finish them on Tuesday as well.  The high winds (nearing 30MPH) have been drying things out a bit faster than we would like, along with bringing many small branches and maple seeds down.  Tuesday we will topdress the greens one more time, drag and roll again.  Water will be used to help settle the sand and by the end of the week we hope to resume cutting the greens.  The forecast calls for frosts this week which may slow the recovery which normally takes about 2 weeks.


After the holes are filled with sand the greens are rolled to help smooth the surface.

April 6, 2012 Scouting Report

30s at Night. A Hard Frost, Issues Slow Down, Dollar Spot, Rhizoctonia sp., Crabapples and Lilacs Bloom, and Tim's Tall Fescue ABC's

Chicago/Northern Illinois Update: Derek Settle - DSettle@cdga.org/Weather Blog

More normal temperatures? Yes, is the answer to that question this week. Since March 26th we've had low temperatures dipping down into the 30s and 40s in Chicago. We didn't complain as it represented a return to normal spring weather - we have written records of these temps! It did mean that sooner or later a hard frost would happen and it did. I would find that out in an email today. This morning news from Sunshine Course came - with a request. It said, "There is frost on the course this morning, please refrain from going out on the course until 10 a.m. this morning." The early activity of emails and phone calls with which I had been involved, especially early this season, went away. The communications dropped off as quickly as our nighttime low temperatures had. Instead, in a week, I was happy to watch lilacs and flowering crabapples begin their bloom. The two combined expanded our color palate beyond the early woodie ornamental display of yellows and whites. As far as applications go, some superintendents would be making their second timed-application to prevent Poa annua seedhead development on golf playing surfaces. On little Sunshine Course in Lemont, as well as others, our first fungicide would be necessary to suppress dollar spot which perhaps enjoyed its earliest development in a given season. What a string of 80s can do for you in March! Next up? Easter!

Have a great weekend and Happy Easter!

April 2 - More Normal Temperatures

It feels a bit cooler, but we now seeing more normal temperatures for this time of year.  Turf growth is slowing a bit with the cooler temps.  Next Monday we will be aerify the greens with the smaller tines and filling the holes with sand.  Don't forget, flower orders are due in a few weeks!

In preparation for aerification, greens and tees are fertilized to help them heal quickly.

Each spring the brick work around the property is checked and repaired as needed.


We are quickly catching up on the "To Do" list.  Bunker work is complete and edging of cart paths has begun.

Daffodils are in full bloom!

CDGA Weekly Update - March 30

March 30, 2012 Scouting Report

Back to Normal? 30s at Night, Dollar spot, Dandelions, Henbit, Chickweed, Ground Ivy, Creeping Speedwell and Tim's Poa annua encroachment data

Chicago/Northern Illinois Update: Derek Settle - DSettle@cdga.org/Weather Blog

Another week for us to reflect on this season. Here goes. We've returned to more normal temperatures and we caught some needed rainfall. The redbuds continue to flower nicely along with the Korean Spice viburnum. Crabapples have just begun and today I saw my first lilac begin its bloom as well. Another first report of dollar spot, this time a far north suburb. Our March was unlike that of any other spring. - such a rapid warmup so early. So, I have been fielding calls from golf course superintendents as to when to begin applications for you name it - seedhead suppression, prevention of fungal diseases and preemergent applications to prevent annual weeds like crabgrass. The next question is what to do. Same usual interval, or should we try to stretch it and hope normal/cooler weather to smooth out the rest? I usually respond, "Ummm". It turns out, we are all dumbfounded by 2012. How do I know? Most often I have these conversations with the best and brightest who, by their very nature, are most experienced. That says something of superintendents - that a gifted and experienced plantsmen would have no memory of a spring like this ever happening. And that's 147 years worth - weather chroniclers and our landscape continues to see new data (green up and flowering dates). Our pencils need sharpening - already.

Have a nice weekend and enjoy a more normal spring.
