Hydrojecting of greens/collars

(I originally attempted to post this on the day it occurred, Monday 7/20 but the video would not upload for some reason. Google must have a glitch in their system that did not allow some files to load properly. Well, the video will not upload so here is what we did last Monday with our greens)

During the summer months, we utilize an aeration contracting service to perform the hydroject aeration process on our greens. This service is used during the more stressful times of the season as a tool to improve air penetration to our greens and assist water to move through the profile. The last two weeks have been unseasonably cool and has helped tremendously in improving the health of our greens. It appears that summer will be coming back over this next weekend. We have another hydroject aeration tentatively planned for the middle of August.

The links below will give you an idea of how this aeration process works. There were 3 units operating on our course. They began a little after 6:00 a.m. this morning and were off property by about 10:30 a.m. We could have mowed or rolled right after the process but decided to let our greens rest today since we were closed. We chose to leave the machine in an uplifted position which gave us a slightly larger hole and deeper as well. The holes remained slightly open during the week but began to close by Thursday and Friday of this week. Rolling a few balls across the practice green and watching member's ball roll across the greens, it appears that ball roll is not affected. If the weather stays mild through the next few weeks, we will probably not do a second hydrojecting in the middle of August and will stick with our needle-tine operation using our verti-drain and tractor.
