“Sorry if this is a rubbish question”

This question came some months ago: “I’m just pondering something about MLSN levels for Bent vs Poa and so hopefully you can clear it up. Having seen a bit of research coming out about k levels affecting disease pressure differently for poa and Bent does that not mean there should be two different MLSN’s for… Continue reading “Sorry if this is a rubbish question”

The two green system usually means there are two bentgrass greens per hole

The idea that golf courses in Japan with the two green system have a summer green and a winter green is not quite correct. Nor is the two green system used exclusively with one warm-season grass green and one with cool-season grass. Trevor Dormer and I had a brief discussion about this. that's correct.. Some… Continue reading The two green system usually means there are two bentgrass greens per hole

Preventing nutrient deficiencies

The recording of my webinar on preventing nutrient deficiencies is now available in the videoteca section of the Campus del Césped website. Or watch the English version right here. This was fun. I hope you’ll read the handout too. It is only 4 pages, with lots of white space, and gives a brief overview of… Continue reading Preventing nutrient deficiencies

How to lose 120 million yen with frost delays

I’m bombarded at this time of year with reminders, notices, descriptions, and articles telling me about the importance of frost delays. Apparently, frost delays are essential for the health of the turf. Allow play on frozen or frosted turf, and the leaves will turn brown and start to die. In a worst case scenario, recovery… Continue reading How to lose 120 million yen with frost delays

Fall potassium and winter traffic on a bentgrass green

I just finished reading Winston Mirmow’s thesis on Fall potassium fertilization and winter traffic effects on a creeping bentgrass putting green. I downloaded this in September and read the abstract then, but only read the full thesis now. As I’ve mentioned previously, I like reading theses, because they are the most recent research results presented… Continue reading Fall potassium and winter traffic on a bentgrass green

Applying the grammar of greenkeeping

Over the past two weeks, I’ve had multiple conversations about the way I think of turfgrass management. It all starts with a definition of greenkeeping as managing the growth rate of the grass. I wrote about this in A Short Grammar of Greenkeeping. You can get your copy here. Application of the grammar allows for… Continue reading Applying the grammar of greenkeeping

Another interesting technique to modify fairway conditions

I’ve seen introduction of seashore paspalum to bermudagrass, and manilagrass to bermudagrass, by hand planting the introduced species into slices cut into the exisiting turf. This post shows seashore paspalum planted into a bermudagrass fairway using that technique. I’ve also seen resodding to convert to a different grass, but in a way that doesn’t require… Continue reading Another interesting technique to modify fairway conditions

Every spring when the snow melts …

I look forward to some photos from Doug Soldat. For the past three years, he’s had some fascinating photos to share of snow mold on creeping bentgrass. And each year, there was more snow mold where potassium fertilizer was applied, and less snow mold where potassium wasn’t applied. Spring of 2014 In the spring of… Continue reading Every spring when the snow melts …
