    What's the general rule of thumb on this?

    How longer after it has been laid, what application, etc?

    I've seen where some people fertilize the ground before laying the sod.. I would be careful doing this though it's been known to burn .. I've also worked for company's that throw the fertto it right after it is laid .. I personally wait about a week by doin so it helps prevent shock...c

    Our specifications require contractor to add amendments, including fertilizer, to soil before installing sod. This has always worked well for us.

    I have always found liquid fert foliar applied to be the best for new installs. I like a high P & K for root development. I try and stay away from over application, so I don't burn the new turf.

    Yes. WATCH yuo NITROGEN! Especially with this heat. Go as low as you can, and not at full rate. Actually, if you went with a straight sulphate of potash right now, it wouldn't hurt you, but it would be nice to find a combo with a lower N and a higher K.

    If you really want to know the right answer.....do a soil test before installing the sod.

    Then you will know exactly what to apply.

    Wait until the sod has become established before you start making your fert/weed control applications.

    Try some Milorganite 6-2-0, it is an organic fert with very low burn potential.
    That is what we did when I worked at Camden Yards and it worked for us.

    I go back to the soil test thing again because it is important.

    If you test and find low Phosphorous, then it would be necessary to apply MAP/DAP at the time of installation. Prior would be even better. If your Phosphorous levels are good, then you can wait and apply Nitrogen after the sod has rooted.

    If a soil test cannot be done, the best option is just to apply a starter fert (18-24-12) either prior to or at the time of installation. At 1 lb N/M, burn is not a concern.
  10. yes, do a soil test!

    Whenever buying sod, you need to ask the grower the last time he fert, what he used, what rate/m, what % controlled slow release n.

    When you fert will depend on info from grower, soil test, what nutrients applied in preping the soil, and your particular micro climate
