The
dry spell that started in July continued into August (14mm August rainfall) and
we’ve kept the greens relatively dry. As
always when our greens are dry the pace of the greens picks up and during
August green speeds were generally between 10ft and 11ft, with an average of
10ft 9in and a high of 13ft 4in. 13ft is
the upper limit (some would say beyond!) of playability for our greens, with
very few workable pin positions and the likelihood that balls would blow off greens
if any breeze picks up. It’s worth
noting, that the very high green speeds we’ve seen over the last few weeks are
a side effect of drying out the greens to favour the finer grasses, we haven’t
dried them out to get more speed. Our
routine target for green speed is between 8ft and 10ft but we aim to keep them
above 9ft whenever possible.

Work
programme for September
Our
main aim for the next week or two is to promote recovery from the over-seeding
work and get the greens back to normal as soon as possible. As soon as the top dressing that was applied
this week has integrated into the sward, we’ll do another light top dressing to
smooth out the putting surfaces. The greens
will be a little slower for a while as we increase irrigation to boost
germination of the seed.
We
have delayed the application of Rescue to the approaches as it is unwise to
apply this product during a dry spell.
It selectively kills ryegrass and other coarse grasses in turf but will
kill other grasses if they are under stress.
This work will be carried out over the next two weeks. After treatment the areas will thin out for a
while with some bare patches and a general yellowing of the turf but they
should recover after a few weeks. The
approaches will be over-seeded with a mixture of fine fescue grasses with high
wear and drought tolerance. Bracken
control will continue using Asulox and we’ll be spraying off encroaching scrub
and brambles. We’ve just started a
programme of replacing worn out sprinklers as most of them are now 18 years old
and are becoming unreliable. Work has
started on the 10th hole and we intend to replace the sprinklers on
two or three holes per year.
