Shades of Bermuda

Bermuda is a fantastic turf for golf. It can take all sorts of abuse, drought, traffic, and maintenance practices and bounce back quickly. Recently, we've really put bermuda to the test, with some scalping in new low-cut areas and aerification of the fairways. Below is a good example of recovery from scalping. The green surround on the par-3 9th hole was trimmed down and went brown for a couple weeks. It's now green, heathy and smoother than ever. These new areas are giving our members more shots to consider and helping to eliminate undesired grasses.

Over the past two weeks, Bernardo Heights has installed 62,000 square feet of new bermuda grass. This new turf replaces half an acre on the 18th hole, all the collars, a long strip along the range tee, and many locations in the fairways.










I've had many questions about the project and the new turf, so here are some of the most common:

Will the new collars go dormant?

The collars are Tifgreen 328, a fine leaf, hybrid bermuda. This was chosen for a few reasons. It can be mowed very short, it moves laterally less than other warm season grasses, we can overseed it, and it plays well. Yes, it will go dormant, but not like the paspalum we've been dealing with. Also, we will seed in winter with Poa trivialis, which provides a green cover in the cool months, but transitions quickly and dies when it warms. 

Is the sod OK, it looks a little brown?

Whenever we lay bermuda sod, it is very common or standard that the sod goes off color, sometimes solid brown. This is the turf going into a defense stage. It puts all its effort into sending down roots and the leaf tissue above will turn brown. It will green up soon and already has roots down 4 inches in about 10 days. Please don't going looking for roots like this yourself, you'll have to take my word for it.

Why do some fairways look better than others after aerification?

I've always felt that the fairways that get torn up the most are the ones that need the most work. This past week, we have been solid tining (not pulling a core) the fairways with our big tractor-mounted aerifier. Hybrid bermuda sections show very little damage. This includes most of #5 and #17. It almost looks like we didn't do anything, but there are many, many holes to get oxygen into the soil, improve infiltration of irrigation, and relieve compaction. Where we have common bermuda, most of holes 4, 7, and 10, the turf gets ripped up. Lateral runners of 4-6 inches are severed and pulled up during the process. We drag the fairway with a large mat and then mow off the plants above our cutting height. This is excellent for bermuda. It might turn brown for a few days, but where the bermuda is cut, new growth is stimulated and fresh, healthy leaves replace old tired stems.

 Why did we renovate #18?

This area is shaped like a bowl. Insufficient drainage caused sodium from our irrigation to pile up and turf to thin and die. Instead of continuing to core out and replace patches, we spent some money and did it all the right way. The root zone is deeper and healthier with quality sand blended into the existing topsoil. There is 1000 feet of new drain lines which will prevent the sodium from building up again. Irrigation heads have been moved and added to improve coverage. Finally,  3 to 4 types of bermudagrass is now one uniform variety.


I love the strength and durability of bermudagrass. I appreciate the many shades, and this summer, I'm sure you'll all be seeing more green than ever before. 

New Collars are Coming

Paspalum has been a dirty word around Bernardo Heights for a very long time. The green collars, installed about ten years ago, have never been enjoyed by the membership. This turf is a bit sticky, nicknamed velcro by many players. The winter conditions have been poor, overseeding unsuccessful, and even when it looks good, it doesn't play particularly well.

Over the next few weeks, the collars will be removed and replaced with bermuda 328. This surface will blend nicely with the fairways and green surrounds and new collection/low cut areas. Overseeding will take place in the winter to maintain year-round playability and aesthetics.

The first step in this process is removal of existing sod and a portion of the soil below. USGA sand will be installed, compacted and graded before sod is laid down. While the crew is completing their tasks, we will have temporary greens in place. Speaking with some members today, I apologized for the inconvenience of temporary greens and the response was an emphatic, "do whatever you gotta do!!"

Another project, that actually is well underway, is the renovation of #18 fairway. We've battled this section for years, with many aerifications, topdressings, tons of soil amendments and conditioners. It has improved, but not nearly to the standards we expect for our members. The problem is dense clay soil below the 4 inch sand profile of the fairways. Drainage is not sufficient to drain excess water and salts, we are unable to flush the soil like we do on the greens.

Long time members may remember a similar situation on the 17th fairway. This area was a "salt bath" and plagued by the ill effects of bad water, even though it was potable water at that time. Now, our well water, with three times the sodium we used to battle is finding new areas that need a little help. Just like the front half of 17 fairway, we will install drainage and sand to give new hybrid sod some breathing room. And, just like the front of 17, your closing hole is about to be gorgeous.

To make the most of this project, much of the sod coming off of 18 is quite good and will be relocated in other areas. Our staff installed about 2000 square feet on the range floor yesterday and they are busy prepping locations today to use as much as we can.




The excitement around the club is obvious. The grand opening for the reinvented clubhouse was just weeks ago and now new collars are coming. As a bonus, the 18th hole is getting a facelift. Things have never looked better and we still have a very long ways to go.
