What to do about Crabgrass this year

With the warm temperatures last week and the possibility of an early spring, the question arises  - When do I put my Crabgrass preventer down?  Here is a great video recently posted by the Ohio State Turf Team:

A few things to consider:

• Findlay is about 1 week behind Columbus in terms of phenological events in the spring transition.
• If you apply your Crabgrass preventer too early, the product will lose its efficacy earlier causing more weeds later in the summer (August and September).
• Any crabgrass that happens to germinate in the near future will most likely be killed off by a frost.
• The Crabgrass preventer being sold in our home lawn program has pre and post-emergent activity, providing control on young crabgrass plants.
