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.
