now, most golf facilities in the Mid-Atlantic region have completed one, if not
multiple, management techniques for the putting surface and/or soil profile. These
include but are not limited to core aeration, deep-tine aeration, vertical mowing
and Poa annua seedhead control.
aeration is beneficial to prepare the turf for the upcoming season. Combining
core aeration with deep-tine aeration will further enhance turf development
especially on soil-based greens. Deep-tine aeration of fine-turf areas to
shatter zones of compaction and create channels for root growth can be performed
as time, weather and resources permit. Small-diameter solid tines, often
referred to as pencil or needle tines, improve turfgrass rooting and water
infiltration while offering minimal disruption to playability.
there is a need, vertical mow putting surfaces as long as favorable weather is
present. Doing so will sever plants growing laterally and lead to more vertical
growth of the turf. Ultimately, vertical growth leads to a denser stand of turf
and creates smoother putting surfaces.
aeration treatments that may be performed are drill-and-fill aeration and sand
injection. Both of these methods allow sand topdressing to be incorporated into
the soil profile which ultimately helps to firm surfaces and improve water
infiltration. Virtually all aeration techniques provide some surface
disruption, but short-term disruption pays off with season-long benefits to
turf performance and playability.
many, it is time to apply preemergent herbicides if they have not been applied
already. Proper timing of preemergent herbicides is largely dependent on soil
temperature. As soil temperatures reach an average of 55°F for 24 to 48 hours,
crabgrass will begin germinating. Preemergent herbicides must be applied and
activated by irrigation or rainfall prior to crabgrass germination for
effective control. Cold spring temperatures have dulled the sense of urgency
for these applications, but time is getting short with warmer temperatures
becoming the norm.
applications to control adult annual bluegrass weevils (ABW) have been
initiated in many parts of the region. Following a very cold winter, timing
applications for ABW may be slightly different from past years, so scouting is
critical. Scout known hot spots for activity. Once your threshold has been
reached, apply an insecticide with curative control of adult ABWs to those
