After mowing in
early spring,
apply a fertilizer with pre-emergent weed control following the label directions. Scotts makes Halts Crabgrass
Preventer® or Turfbuilder with
Halts®. Most garden centers will have these
products or similar herbicides. Repeat this application at 1/2 rate in 8 weeks.
In poor soil
conditions or Southern climates a third fertilizer
application, without pre-emergent, may be done in
mid-summer and a fourth application can be applied in
early fall.
Throughout the
summer, Broadleaf
weeds such as dandelions, clover or pigweeds can be controlled after they emerge
using broadleaf weed herbicides without 2-4D or a
granular weed and feed. Products like
Scotts Turfbuilder Plus2® , which contain 2-4D, can be applied when the temperature is below 85
degrees Fahrenheit.
