Freezing and Thawing

Freezing and Thawing
The forecast for the next week is calling for freezing over night lows. This will lead to the greens becoming frozen at night and thawing during the day since the weather still reaches the fifties during the day. The constant freezing and thawing we will experience may arouse some questions about course condition. I wanted to write this post to hopefully help answer any questions so you are prepared when you play golf over the next few weeks.

Since the weather is not constantly cold the top few inches of the rootzone will freeze over night. Not only will this begin the hardening process and start to turn the grass off color but it also addes oxygen to the top few inches of the soil.

We all know when the pipes under the house freeze, the water inside expands and the pipe breaks. The same process happens when the water in the soil freezes it expands, enlarging the pores in the soil. How does this affect you? Soft playing conditions.

With the constant freezing and thawing that takes places the greens will become much softer once they thaw. The green will be much more receptive and can feel spongy. This is all collectively the freezing overnight weather. We are not overwatering greens. Actually we have not watered greens for a couple weeks now, even though the temperatures have been elevated and there has been no percipitation.

When you tee it up in the weeks to come and you find the greens are a little soft and spongy, it is because of the freezing and thawing conditions that are upon us.

If you have any questions please feel free to contact me.
