When is the best time to put down fertilizer this spring?
What about crabgrass prevention? I believe I can only do one or the other, correct?

Thanks for your question. Here is a quote from one of our other experts:
You may want to consider obtaining a soil test before applying fertilizer to your lawn so the correct amounts of nutrients are used. Information on obtaining soil tests from the University of Minnesota may be found at their website: http://soiltest.cfans.umn.edu/how-to-submit-samples/lawn-garden/. Due to differences in timing requirements and watering needs following either fertilizer or weed control applications, combinations of fertilizer and herbicides (weed and feed) products are generally not recommended. The one exception is applying a crabgrass preventer in the spring where the timing coincides with a spring fertilizer application. Crabgrass control products are usually best applied in early May when soil temperatures are in the 50s.
