Answer: Let's start first with some cultural control suggestions. You can dig the crabgrass out. It's labor intensive, but effective, and easy on the environment. If you prefer to use chemical control, just remember that crabgrass germinates January through March, and continues to germinate through the summer. Apply pre-emergents before the end of January and again in late May. You can use the synthetic products you describe, or you might try the organic alternative called WOW. This pre-emergent herbicide, a by-product of corn syrup production, controls controls crabgrass and contains nitrogen fertilizer to nourish your lawn.
