    How much time should a person wait to apply "fall" fertilizer after installing a new lawn? Or should fertilizer even be applied this fall after a newly seeded lawn in the fall? Wait till spring to continue the fertilizer program?

    Cool season grasses use the fall fert to get ready for winter... My last fert app is about 6 weeks b4 expected ground freeze... The 2nd to last app is 4 weeks before the irrigation is shut off, and that is the one I count on most...
    Another dry Oct doesn't do much for the last winterizer app., but the roots should continue to dig deeper, with energy from the previous app... :)

    Fert is fine in the fall just make sure there is no pre emergent in it or you will waste your seed.

    i was always told you want to use less nitrogen and more phosphorus when fertilizing over new seed. that comes from my nursery. dont knwo the truth behind it but it works for me. just did some the other day on my own lawn.

    This is why you use a starter fertilzer when you seed.

    Go ahead with the Fall Fertilizer, don't wait until Spring. Guys have mentioned a "starter" fertilizer but I've had the same results with a starter and a fertilizer I use on a mature lawn. i don't think it makes that big of a difference. Just make sure its got Nitrogen.

    Go with the starter fertilizer if it is new seed or brand new grass. It needs the phos and certainly needs the higher potassium rate. A heavy nitrogen can and will cause a hindrance over the overall health of the oncoming turf. Excess top growth will not only take energy way from the immature seedlings' root establishment, but can also cause fungus of different types due to too much leaf growth going in to the winter months.
