    I live in NJ and yesterday i aerated, put down seed, and a starter fertilizer. My question 6 weeks (First week in Nov) should i apply a fertilizer again something high in N or just the application of starter fertilizer be good until my Spring app? I have read that applying ferti too late will cause the grass to continue to grow when it should be going dormat and that will cause snow mold. I also heard that it is the best time to give your lawn nutrients to store for the Spring. Thanks for your help.

    For our average seasonal development into winter, I've settled on my own date for final application: 15 Oct... The local Extension Office claims that we should have a Thanksgiving Application for our Winter Dormancy...

    We were given an article last Fall, on this Forum, that begin to analyse the "Happenings" or interactions between the fertilizer, itself and the plants' ability to assimulate it, absorb it, use it and turn that energy into storage for the plant...

    I think the answer is: "What in the World would the plant do with fertilizer during dormancy???"
    ,,, but we all know how "Research" works and how long it takes,,, so it might be a while before "Research" says that plants don't "Metabolize" ferts during periods of dormancy, under winter snows... They do agree that it causes snow mold...

    Put fertilizer for winter on the turf at least a month before the ground is cold and root activity has slowed to a stop...
    Right now our turf is growing rapidly and building reserves for the winter, so this is the time for food and water, but remember,,, too much of either food or water generally causes more problems than anything else...

    The plant takes the N and stores it as a carbohydrate, the roots continue to grow till the ground freezes. I think mowing short after first hard frost is really important, seems that I see more snow mold on grass that isn't cut short.

    Keep in mind that under the NJ Fert Law, homeowners may not apply fertilizer after Nov. 14. The cut off date for professionals is Nov. 30.

    Snow mold is not a very common problem in NJ although it does exist under the right circumstances.
