Why are greens so susceptible to high temperatures?
Greens are the most susceptible to high temperatures because of the low mowing height. With so little biomass the plant cannot sustain the heavy injury that turf at higher mowing heights can withstand. Syringing implies a light application of water to the green surface in its entirety.
Why do golfers use aeration holes?
Aeration holes allow excess moisture to evaporate and promote gas exchange in the soil, result ing in stronger root systems and turf that is better able to tolerate golfer traffic. The addition of sand, both firms and smooths the green surface allowing for consistent roll and speed.
When to aerate turf?
SPRING. “The first thing that comes to mind as far as seasonal maintenance is aeration. Aeration is performed in late spring and early fall. Core aeration involves physically removing small soil cores from the turf.
Do golf courses require chemicals?
Courses require certain chemicals to remain playable. Eric said, “There is a plethora of chemicals and nutrients used on sports turf surfaces. From greens, tees, rough, fairways, to clubhouse lawns, all are treated specifically to their own needs. Soil tests are preformed throughout the year on all surfaces to determine exact nutritional needs and applications are made accordingly. Fungicide and Insecticide applications are based on timings of disease and insect pressures. All chemical applications are posted at the Starter Shack.”
How do I install drainage in golf greens?
To install green drainage, we mainly used the herringbone drainage system, which means there are wings that stretch out into different segments of the green. We dug a trench, usually using a trencher, though sometimes with a mini excavator. The trench needed to be eight inches deep for each section, where we would then place in perforated pipe, filling all around it and back to the surface with gravel. All of these were connected and drained off the green into non-perforated pipe, which runs away off the course. We used the same process for putting drainage in bunkers as well.
How to prepare greens for Overton Park?
Here is a look inside the process to prepare greens at Overton Park. 1. Smoothing things out. Most of the greens at Overton Park were not particularly smooth after sitting out in the elements for a few weeks. There were low spots from rain, bulldozer tracks and windrows over much of the surface.
What is keying in greens?
Keying in greens is Collins’ least favorite part of the entire construction process. The good news is we didn’t have to do this all the way around every green. Keying in a green is done before laying sod around the perimeter, usually in a spot with lots of slope that could force a washout on the green if left alone.

Why is sanding greens important?
The green might get spongy, or develop brown spots, or become vulnerable to scalping during mowing. Sanding helps protect against all that. That’s not all, Kidd says. Sanding also improves drainage and helps level out the green, creating smooth, consistent putting surfaces, and firm, fast conditions year round.
What is golf sand made of?
Golf course sands are different. They are made of round particles “resembling a bucket of balls with large pore spaces between each ball ,” Kidd says. They promote good drainage, and healthy air and water circulation.
What happens if you use wrong sand in a green?
Using the wrong sand, Kidd says, can adversely effect the movement of water and nutrients upwards and downwards through the root zone.
Why do you aerate greens?
Aeration comes in when soils are heavily compacted or the turf is thick with thatch. The greens get punched and sanded, and the sand is worked into each aeration hole to improve air and water flow, giving the roots a better chance to drink and breathe. There is, of course, plenty more to the science of sanding.
Can you chip and pitch on a putting green?
You might not wind up with a patch of grass as pure as a putting green, but you’ll have a pretty sweet place to chip and pitch.

Do golfers have dislodgeable residues?
Although carefully conducted studies have measured dislodgeable residues during some golfing activities, little data exists on the frequency with which golfers actually engage in activities that increase their level of chemical contact during a round.
Do golfers have pesticides?
There is also a lack of data regarding the variability of these behaviors among golfers. Perhaps more importantly, there are few systematic studies of all of the potential golfer behaviors that would increase pesticide exposure during a round of golf.
What irritates golfers more than anything?
What irritates golfers more than anything, of course, is when they show up for their tee time, only to find out then that the greens were recently aerated, or worst yet, don't discover it until they get to the first green. The latter is certainly rare, and the former is becoming less common, too, as courses know this doesn't exactly create good will with their customer base.

That improves drainage and air exchange for the plants. It can take up to a couple of weeks for the greens to recover, but these procedures are critical for the long-term health of the greens.
Do golf courses send out alerts?
As all of us have become more tied to our phones and computers, and facilities have extensive emailing lists, many courses send out alerts to their regular customers, letting them know when greens are going to be aerated. And most courses will inform golfers who reserve a tee time by phone if greens have been recently aerated. (It saves a lot of potential grief for shop personnel later).
Can you play rough greens after aerating?
Golfers looking to save a little money on green fees who don't mind rough greens would be well advised to check out course websites and get on mailing lists. Sometimes, the greens are surprisingly playable following an aggressive aerating, especially if you wait a few days after the procedure when the maintenance crews have had a chance to "whip" the sand off the greens and run the mowers and rollers.

Why do we put covers on greens?
In the Northern regions of the United States, maintaining greens sometimes includes placing covers on them to protect them against harsh winter weather and speed up the greening process during early spring. Covers also stimulate grass growth on newly installed or renovated greens, especially those that are seeded late in the season.
What is green cover?
Green covers are made of a wide range of permeable materials, from geo-textile fabrics to woven and solid polypropylene sheets. Most covers are treated to block ultraviolet light and designed to be rot and mildew resistant. Green covers range in price from several hundred dollars to a few thousand dollars apiece.
Why do superintendents cover greens?
One of the main reasons superintendents in the Midwest cover greens is to prevent wind desiccation, Miner says. “The wind can really howl around here in the winter, and the farther west you go – out to Montana and that area – the drier the air gets.
