Control
of Broadleaf Weeds in Home Lawns
Zac Reicher and Clark Throssell, Purdue University Turfgrass Specialists
 The
fall represents the best time to control perennial broadleaf weeds
such as dandelion, plantain, and clover. These weeds are storing
energy reserves for the winter in their roots. Thus the herbicide
will enter the plant and travel to the roots with the food reserves,
thereby giving a complete kill of the weed.
The second best time
to apply herbicides is in the late spring or early summer period
after the weeds have flowered. If applying in the late spring, be
extremely cautious with these herbicides near ornamentals, trees,
flowers, and vegetable gardens because these plants can be damaged
by these herbicides through direct application, drift, and/or volatilization.
This is one of the reasons we prefer to apply herbicides in the
fall.

Fertilizing
Established Lawns
Zac Reicher and Clark Throssell, Purdue University Turfgrass Specialists
You may think that you
should fertilize your lawn in the spring, but the Purdue experts
say fall is better. Spring fertilizing can cause excessive leaf
growth and can stimulate disease, weed, and insect activity. Fertilization
in the fall encourages better root development and produces a healthier
lawn year-round. If you haven't fertilized yet this fall, try an
application of quick-release nitrogen from November 1-15 (late fall).
