About 5 weeks from now, April 20 & 21 to be exact, the Green Dept will be conducting the standard procedure of green aeration. For our new members this process is completed twice a year, April and August with the only difference being the diameter of the holes. In the spring we use 1/2″ tines and 5/8″ ones are used in August. The smaller hole in the spring leads to a quicker healing time. This can be especially beneficial with the normally cooler soil temperatures. The normal recovery time is 10-14 days this time of year. You make want to look into other courses to play if these conditions are unacceptable to you.
If you have questions on green aeration or just want to learn about the process and its benefits
( this applies to home lawns too) please use this link to connect you to a great USGA article on green aeration.
My next blog will discuss the benefits of “deep tine green aeration”.
But opening regulation greens may not be!
This time of year is the most difficult time to decide whether or not to open or close regulation greens!
Here’s the scenario. Right now the soil is frozen under the greens, and any moisture from rain and or melting snow just runs off. When temperatures rise above freezing, the thawing process begins. Excess moisture becomes trapped in the soil since it can’t percolate through the underlying frozen soil. Under these conditions, the potential for turf and soil structure damage is high. Foot traffic under thawing conditions can cause root shearing at the interface between the thawed and frozen soil, causing damage to the root system. Soil structure damage is cumulative depending on amount of play and soil moisture levels. Additionally, minor-to-severe foot rutting can occur, causing short-term and possibly long-term surface-smoothness issues. To me it makes no sense to risk damaging the greens at the beginning of the golf season. Luckily, its only about a two week time frame in which this happens, but keep in mind it’s the weather that dictates this time frame. On a more positive side, we pretty much know what greens will thaw first; full sun greens, ex. 4, 5, 6, 9, 10 etc. And those that take the longest 1, 2, 3, 7, 14 etc, which are shaded.
As in previous years, we will open the regulation greens when they are completely thawed to ensure they are not compromised going into the golf season.
I hope this explains the Green Dept’s March madness with your golf course!
