Flights and favorite turf photos of 2020

This is usually where I show a map with all my flights, mention that they took me some hundred thousands of kilometers, and then share some of my favorite turf photos from all the places I went.

Radish seedlings on a bentgrass nursery after fumigation

Last November I saw a creeping bentgrass nursery in Japan. The nursery had been fumigated to kill seeds in the soil before the bentgrass seeds were planted. I was surprised to see, scattered across the nursery, plants with big leaves that clearly were not creeping bentgrass.

Winter grass color, zoysia, and soil

I was in Fukuoka last weekend and enjoyed the mid-winter weather and the seasonal colors of the turf. This is what golf courses in Japan look like in the winter.

Flights and favorite turf photos of 2019

At the end of every year, I like to look at my flight map and at some of my favorite turf photos. In 2019 I was on 56 flights over 161,473 km (100,335 miles).

Putting green speed, surface hardness, and clipping volume

Last week I had a couple conversations about green speed. Green speed and surface hardness My column in the June 2018 issue of Golf Course Seminar magazine discusses the relationship between effective mowing height and green speed.

Cleaning cores the easy way

On a recent trip to Japan, I’d wanted to get a new video of a core sweeper in operation. Unfortunately for me, but fortunately for the greenkeeper, who had a laugh about this, the sweepers clean the greens so fast that by the time I arrived there were no more cores to sweep.

Grass on the Kumamoto City Tram lines

I went for a walk in Kumamoto yesterday morning to take a few photos of the grass on the Kumamoto City Tram. This page shows how the grass sections are installed.

Ball bounce on greens after 7 days of rain

I’ve been at Keya Golf Club for the KBC Augusta tournament this week. Yesterday afternoon I watched some shots during the first practice round, and took a few videos of ball reaction on the greens.

Half-aerified greens; sodded fairway stripes; with other interesting and informative matters

Mike Richardson shared an image of aerifying half a green at a time. The purpose of this, the superintendent said, was to always have a good surface for the hole.

Is it temperature or day length?

Andrew McDaniel asked me if day length or temperature has a bigger effect on zoysiagrass going into or coming out of dormancy. I hadn’t really thought about that before. When I did think about it, I realized I pretty much only think of temperature, but I wondered if living in a tropical location where the grass doesn’t go dormant might be blinding me to something that happens where day length varies.
