Spring Greens Aeration 'DryJect'



Our spring greens aeration was completed today using a process called DryJect. We contracted with DryJect Tennessee who brought two machines to Glen Echo to do the work. The following process was used for all 19 greens at Glen Echo. Our staff did an excellent job in getting this operation completed today!
  • Greens were mowed to create a smooth surface since we will not be mowing for the next few days to allow the sand to settle into the canopy.
  • 5 gallon buckets of sand were placed in the hopper as it crossed the green and were continuously added as it crossed back and forth across the green until the green was completely aerated.
  • The machine uses a bead of water shot at 3,000 psi into the surface of the green. Simultaneously sand is injected into the water. The sand fills the space created in the green subsurface to a depth of 4-5".
  • Once the sand dried on the green surface, the greens were brushed and holes were changed.
  • Tomorrow, we will rolling the greens to help smooth out any imperfections.
We expect the greens to heal over the next 10-14 days. The holes are completely covered and should not create a great deal of disruption in ball roll out.

This process improves water infiltration/drying of wet areas, root growth, thatch control, gas exchange, smooths the surface of the greens with the excess sand that was brushed around the surface, and helps to protect the crown of the plant which is the area where the roots grown down and leaves grow up.

Weather I'm Right or Whether I'm Wrong

Well, it appears the end might be in sight but I'm skeptical for this weekend. Course still has some snow cover and all greens are covered and frozen. I could not get a spike down past 1/2" in the surface on the greens. Predictions of 7/10" of rain and 60 degrees could give us the final push of snow going away as well as thawed greens.  We will alert you once the thaw has happened.

And by the way, Welcome Back Party in the clubhouse tonight so plenty of activity at the club even if it does not include knocking the little white ball around.


In the meantime, think ah yes

Weather Stats for February

Thought the weather of February was worse than it was but the first 
week of March has already made me forget about February. Just kind of
an average month of temperatures, a little below normal temperatures
and rain slightly above and snow slightly below. 18 degrees below
normal for the month of March so far. Heading up the scale to more normal 
in a few days, at least we hope.
