DryJect Aerification on SVGTC Greens

Yesterday was our first time using DryJect aerification on the Siebel Varsity Golf Training Complex greens.    The DryJect machine utilizes a high pressure water jets to make small holes, then using the Venturi effect, sucks sand in to fill the holes.  It is minimally disruptive, but very effective in opening up the thatch layer with a sand filled channel.  Here is a short video showing the machine in action:

The results are impressive, as shown below in a core sample.  A beautiful sand channel penetrates the surface thatch layer allowing water to easily flow downward into the profile.

Worms are Gone, Moths are Here!

Most of the oak worms on the Coast Live Oaks have now pupated into moths.   Here is a video of the numerous moths buzzing around.  Their role in the life cycle is mating and egg laying.  The moths eat very little, they mostly just lap up dew and moisture.

Fortunately, most damaged oak trees are now showing amazing recovery!  My guess is that within two more weeks, all the trees will be nearly back to normal.  Typically the second generations of worms in the same year are much milder and the damage is far less obvious.  I'm sure hoping that is the case this year!
