8mm in the storm last Saturday afternoon / evening was certainly most welcome.  Despite all the predictions of a wet summer we are still pretty dry at the moment.  As mentioned previously the constant overnight wind has quite an adverse effect on the operation of the sprinklers so a couple of calm nights would be much appreciated.  Some of the roughs, particularly Kikuyu areas have started to grow, and I was asked this week why we don't apply growth regulators to the roughs.  Well on some of the shorter rough we can and do but on the longer rough there is what is known as a ''spray shielding effect'' which is when the length of the grass prevents the spray solution from being able to penetrate through the canopy and make contact with the leaves as required.

The grassing of the edges at 1R green are progressing much slower than anticipated.  There is also the problem of rhizomes of the foreign couchgrass now popping their heads up as can be seen in the photo below.  It appears that we got an excellent kill of all the surface leaf / plant matter but as the rhizomes tunnel under the surface then sprout we weren't able to make contact with them.  The one below is a good 75cm into the green.  We have been painting them to try and control them but time will tell if they get too invasive again.  The ball in the top photo is next to a shoot from a rhizome and the lower photo is a close up, which also shows how much new 328 growth there is which is hard to see from standing so that is encouraging.  It just needs to grow!!

Distance from the edge.
