Mid August is the best time to seed a new lawn or
overseed an existing lawn in central Indiana. Now is the time to be making
plans and gathering the needed supplies if improvements are needed.
Refer to AY-13, Lawn

 Green
Flag for Grub Control Applications!!
If you have been anticipating the 'go ahead' for grub
control applications in your lawn, now is the time to 'let 'er fly '.
Keep in mind that this go-ahead is only for the application of 'preventative'
grub control products.
Visit the Japanese
beetle information page for other information about these pests.
To
Mow or Not To Mow? That's a good question
Summer has definitely arrived, and this year's wet
spring is a mere memory. While the main challenge this spring was to mow
often enough to keep up with the flush of growth, now most areas across
the state are drying up and with that, turf growth has slowed also. During
the dry, hot summer days, mowing can be a significant stress on cool season
turf (Kentucky bluegrass, perennial ryegrass, tall fescue ect.).
Sudden
Death of Poa annua, Poa trivialis on Golf Courses
After three weeks of plus 90° temperatures, the
annual decline of Poa annua (annual bluegrass) and Poa trivialis (rough
bluegrass) on golf courses is occurring now. Poa annua greens and fairways
are starting to thin and die in small patches which may coalesce into
large dead areas with occasional live bentgrass or ryegrass plants interspersed
(see photo). The patches of Poa trivialis in fairways are also starting
to brown and go dormant.
