zoysia greens?
« on: January 04, 2013, 08:13:24 PM »
I know here in the Southeast, ultradwarf bermuda greens have been a hot topic of late.  I think they make good sense in FL, GA, most of SC, but here in NC (at least here in the Triad) I am not sure yet.  We are right on the edge of the transition zone -- it was 28 degrees here last night (and they have to be covered when the temp drops). 

At least a couple courses in our area have recently installed zoysia greens -- I believe diamond zoysia.  How does it play -- I have never seen a zoysia green.  On one of my home courses, we recently had a renovation and put in zoysia fairways that everyone loves, but how does it work on greens?

I have played two Zoysia courses- Pilot Knob and Reynolds Park. RP's were still new when I played them so not much to report on there. I have played PKP many times and have found the greens to be very putt-able but not very speedy until you catch a downhill, down grain putt. They are thatchy and hard to make a ballmark on but hold the ball. Overall I like zoysia. The super at Pilot does a great job maintaining them (as he does the entire course).

Thanks Tom.  Are they slow because of the grass or the maintance at Pilot Knob?

P.S.  We need to meet up -- I am in Greensboro.

When I was at Long Cove (5 years ago?) They were experimenting with a few zoysia greens at Shipyard. Not sure if it gathered legs or not.

 ??? ??? ???

I'm guessing the zoysia experiment will lose steam in due time. It's fairly course, and pernicious . Are they using a hybrid ???

It is a strain "diamond zoysia".  I am probably not fair saying slow at PKP. They are just decidedly faster down grain. The maintainence at Pilot Knob is impeccable. The super there is tremendous.

Zoysia greens play similar to bermuda greens. In fact, to the untrained or semi-trained eye, they will be indistinguishable from bermudagrass. But bermudagrass has the potential to produce a slightly faster and probably smoother surface, so it is the first choice of species in warm-season areas.

This report of putting green performance includes data collected from eight species of grass, including zoysia:

Why use zoysia on greens at all? Zoysia can produce a fine turf with less light than bermuda. Bermudagrass has a higher light requirement. Thus, zoysia can be used in locations where tree, building, or cloud shade restricts the light reaching the grass. That is why there are hundreds of courses in East and Southeast Asia with zoysia greens.

Zoysia is a genus. The species of Zoysia used on golf courses are:

  • Zoysia japonica - japanese lawngrass, more cold tolerant, coarse leaf blade
  • Zoysia matrella - manilagrass, less cold tolerant, very fine to coarse leaf blade
  • Zoysia pacifica - mascarenegrass, tropical, very fine leaf blade

The only species of zoysia used on putting greens are manilagrass or mascarenegrass. The varieties chosen to use on putting greens, such as Diamond (a variety of Zoysia matrella), have fine leaf blades.
