    PH is about a point to a point and a half low. I just overseeded last week. When is it ok to lime?

    It's always okay to lime! It'll never hurt the grass. A lot of people around here lime in mid fall, just before the grass goes dormant.

    I didn't want to go out stomping around on the new grass, should I wait a couple weeks for germination?

    Yeah, you can do that. All I'm saying is lime doesn't matter. I always put it down with the seed. You can wait a few weeks if you want until the lawn is established.

    How do you know when to apply lime? PH test of the soil? are the store testers reliable?

    Generally, without a soul test, one 40 pound bag of pelletized dolomitic lime should be applied to every 1000 sq. ft.

    A reliable soil test, generally the kind you mail to an institution, should, in most cases, provide you with a PH number, and a recommended application rate. If the PH is very low, then you may need up to a few hundred pounds per 1k sq ft.

    And the general rule is, if you have moss, you need lime.

    I had a soil test and was at 5.10, I was recommended to be between 6.0-7.0. I was told to put down 20 pounds per k. You should always get a soil test before any maintenance...it is very useful and cheap!

    Generally, without a soil test, apply nothing. You need to know where you stand. Also dolomitic lime may not be the best choice depending upon the calcium to magnesium ratio. Usually in the east, a high calcium lime is recommended.

    That's true, I may have incorrectly specified dolomite.
