Smoke on The Water... and in The Sky

After a very cool and wet spring, the weather decided to go in a completely different direction as we headed into summer. June, July and August ended up being the driest summer on record, as well as one of the hottest. This combined with weeks of continuous widespread smoke made for a very strange and challenging growing season.

The wet spring we experienced this year created a few problems as we prepared the turf for the heat of summer. Constant rains create lazy plants. Soils stay saturated and the grass plant doesn't have to do any work. The root system remains shallow and weak as the plant gets what it needs close to the surface. Ideally the soil is allowed to dry and the grass plant sends roots downwards into the soil as it searches for water. This creates a deep rooting system, with strong summer hardy turf, capable of standing up to the summers stresses such as heat and drought. This year we had no choice but to head into summer with a less than ideal root system in place.

As things got dry and hot quickly in June we had many areas in the fairways begin to show signs of stress. An outbreak in disease (anthracnose) became wide spread into July and seemed to resist everything we threw at it. We applied wetting agent to help improve soil conditions, we applied granular and liquid fertilizers to try and boost turf health, and finally we had to apply a fungicide. This seemed to slow the disease down, but not completely eradicate it. The hot and extremely dry weather just seemed to never end and it was taking it's toll on our fragile turf.

The wet spring also created another issue in our forests. The under brush grew thick and lush as spring rains doused the forest floor with water. As we got into summer, the lush undergrowth began to dry out as things became very dry and very warm quickly. It was just a matter of time before the perfect scenario for wildfires blew up into the worst wildfire season on record. In turn this created a whole other issue later in the summer.

Smoke. Lots of it. For days. Weeks. Not only is there a serious health concern for those spending a great deal of time outside (golf course workers) but it left us with some unusual and unpredictable growing conditions. The smoke seemed to create a "dome effect" where it trapped moisture and reduced sunlight intensity. The result was a very slow evaporation of moisture from the soil and a flush in turf growth. We struggled to dial in our irrigation needs, as the forecast still called for temperatures in excess of 35C but only would get up to 29C or 30C. Each night we turned down the irrigation run times, and each day the course seemed to get wetter and wetter. What was going on? We've never had to deal with weeks of continuous thick smoke like this before. After a few days we just turned the irrigation completely off. In Early August we went 4 nights in a row with out running the irrigation system and 7 nights without irrigating greens. This is pretty unprecedented for August in Kamloops.

August 2nd - Widespread Smoke
The smoke, although potentially hazardous and frustrating to work with, seemed to give us a bit of a silver lining. The disease areas on our fairways began to clear up and areas that we were struggling with seemed to recover. The smoke was actually giving us some reprieve from the hot dry conditions we were experiencing. Was it just from the moisture retention in the soil, or was there something more at work? Some research is being done on the effects of applying ash (burnt wood) to turf. The ash is believed to have anti fungal properties and could possibly have some benefits when applied at certain rates on turfgrass. Could it be that airborne ash from the wildfires was eradicating our turfgrass diseases? It's certainly possible.

August 6th - Moisture Rentention (dew)
August 10th - Flush of Growth (clippings)
We are currently in another spell of days with thick widespread smoke and it seems that we are seeing the same effects as about a month ago. Moisture retention (we haven't irrigated in 2 nights), a flush of growth (we cant keep up with mowing the rough) and reduced disease on our fairways (a nice bonus).

With all these challenges we faced this year we were still able to adapt and provide a golf course that was in good conditions throughout the tough and strange summer. Our limited staff worked tirelessly to keep things looking and playing great right through the hottest, driest and smokey-est summer, and I am proud of what we were able to accomplish. We are truly lucky to have such talented and dedicated staff caring for the golf course. Thanks everyone! 2017 will certainly be a memorable year!
