when is the best time to apply pre-emergence and will future rain wash it too deeply into the soil to be effective?

Corn gluten meal based pre-emergents should be applied in February as the weather begins to warm. Too much rain can wash it away so wait at least a week - there's a rainstorm predicted for Wednesday - and then apply the pre-emergent. Best wishes with your landscape.
