How many different times of the year should I be fertilizing my lawn? Some commercial companies recommend 6 times. Is that frequency necessary? I live in Springfield, MO. During which months do you recommend I fertilize my lawn? Thanks.

I'm not a fan of overfertilizing and 6 times a year seems a bit extreme. Turfgrasses need nitrogen, phosphorous and potassium for healthy growth (the 3 numbers on the bag of fertilizer). The standard recommendation is to feed in April, June, September and late November. Most fertilizers are encapsulated (time release) so they will slowly release their nutrients over a 2-3 month perido of time. Since fertilizer is expensive you may be able to skip the September application, but the late November application should be made to help the roots and stems of your turfgrass remain strong over the winter months. So, if you want to put your lawn on the best maintenance schedule, feed in spring, summer, fall and early winter. If you're watching your pennies, feed in spring, summer and early winter. Hope this clarifies things for you!
