The Melt

For northern golf courses the biggest winter concern is ice. Both ice that comes in December and suffocates the grasses slowly over time and ice that forms in February and March and causes crown hydration.  Crown hydration occurs when the sun shines on ice on greens, tees and fairways and acts like a magnifying glass melting the lower layer of ice. This melting forms a thin layer of water on the surface of the grass and as the turf starts to wake up from dormancy it fills its cells with water.

Crown hydration is the main cause of winter damage in our area. The danger comes when the sun sets and the layer of water under the ice re-freezes as does the ice in the cell plants. Each time this happens more cells in the plants die until the plant can no longer recover.

To make a long story short snow is good for grass but ice is bad and we want to get rid of it as fast as we can especially in mid to late March when the sun is getting higher and has more power. We have a few methods to help speed up the "ice melt" when we see a warm spell coming. Without human help mother nature can takes days or weeks to melt the ice and snow off the greens. We cannot control mother nature but we can help her out. 

First thing is to remove the snow from the greens to allow the warm sun to melt the ice without melting snow adding to the ice problem. This is normally done with our snow blower but we had so much ice and the right weather this year we were able to use the dump truck and plow to clear the greens.

Plowing the 4th green to remove snow to hasten ice melt. Removing
the snow also reduces the chance of more ice building up from the
melting snow. 

The putting green looks like a skating rink.


Once we are down to the ice we used a combination of mother nature, shoveling the swales where the ice was thickest and darkening the ice to increase melting. We darken the ice buy using green dye and black sunflower seeds.

This area with dense woods to the left (south) is one of the limiting
factors to opening the golf course. The rest of the course is 95% clear
but holes 5, 6, 7, 12, 14, 15, 16 and 23 are covered in snow near the woods. 
To go back 10 days ago the first step to prepare for a warm spell and the resulting melt was James went out on the course and snow-blew paths so we could get around and to allow the water to flow. At the same time he found and cleared culverts and drain basins to ensure the water could go into the drainage system when the melt started.

We mark many of the key drains in fall so they are easy to find in the winter. This year James actually had to use a ice auger to go through the 12 to 18 inches of ice and snow to get down to the drain. It is through this preparation for the melt that we reduce our susceptibility to flooding and damage from water running where it isn't supposed to.

The seeds surround with a quarter for size relevance after the snow melt.
What the birds and squirrels don't eat we will blow off the green.
Sometimes hand work is needed to bust up the ice and hasten the melt. 
This will be my 34th spring on a golf course and the only thing consistent about them is they are inconsistent. This was the fastest I have seen a property go from snow-covered to ice covered to 95% clear in 48 hours. This winter may not be over but so far we are happy with our progress and how the golf course looks for this time of year.
